Investigating Wildlife Disease as a Social Problem
Abstract
Social dimensions define whether wildlife disease is considered a problem, society’s response to wildlife disease, and the available solution space for wildlife health problems. Wildlife disease can have interacting environmental, human health, economic and sociocultural impacts on society, but the way in which society constructs wildlife disease as a problem is shaped by a much broader sociocultural landscape. The sociological imagination, with lines of historical, cultural, structural, and critical inquiry, provides a framework for investigating the social dimensions of wildlife health. The investigation of wildlife disease as a social problem requires wildlife health professionals to work in transdisciplinary teams that include social scientists and to meaningfully engage community stakeholders in a process of cooperative inquiry. The development of effective, real-world solutions to a wildlife health problem demands comprehensive knowledge of the social dimensions of that problem, drawing on diverse social science disciplines, and the implementation of a translational approach to the research endeavor.KeywordsWildlife health sociologySocial dimensionsSocial determinantsSociological imaginationTranslational scienceHarm reduction modelCooperative inquiryCommunity-basedParticipatory

The development of democratic systems is a crucial task as confirmed by its selection as one of the Millennium Sustainable Development Goals by the United Nations. In this article, we report on the progress of a project that aims to address barriers, one of which is information overload, to achieving effective direct citizen participation in democratic decision-making processes. The main objectives are to explore if the application of Natural Language Processing ( NLP ) and machine learning can improve citizens’ experience of digital citizen participation platforms. Taking as a case study the “Decide Madrid” Consul platform, which enables citizens to post proposals for policies they would like to see adopted by the city council, we used NLP and machine learning to provide new ways to (a) suggest to citizens proposals they might wish to support; (b) group citizens by interests so that they can more easily interact with each other; (c) summarise comments posted in response to proposals; and (d) assist citizens in aggregating and developing proposals. Evaluation of the results confirms that NLP and machine learning have a role to play in addressing some of the barriers users of platforms such as Consul currently experience.

Dust produced from mining has the potential to reduce plant cover, alter plant communities, and increase metal concentrations in vegetation—changes that may affect the amount, type, and quality of forage for barren‐ground caribou (Rangifer tarandus groenlandicus). We quantified dust deposition from Diavik Diamond Mine (Northwest Territories, Canada) and investigated the changes on forage quality, type, and quantity for caribou. From 2002 to 2016, dust deposition was measured, and vegetation cover and richness were assessed in permanent plots established adjacent to the mine and in reference areas 1–6 km from the mine. Lichen was collected from areas up to 100 km from the mine to determine metal concentrations. Dust deposition rapidly decreased within 4 km of the mine. Plant communities adjacent to the mine (within 500 m) had disproportionately increased cover of vascular plants and decreased bryophyte and lichen cover. Lichen sampled within 4 km from the mine had greater metal concentrations than those sampled farther afield. Concentrations of Al in lichen collected within 40 km of the mine exceeded safe exposure limits for consumption, assuming lichen comprised 100% of caribou diet. We conclude that dust deposition from mining is altering adjacent vegetation communities but that such changes to forage are unlikely to cause negative effects to caribou due to reduced lichen intake in summer and autumn, their migratory nature, and avoidance of mine‐influenced areas. However, minimization and reclamation of mine‐related disturbances will be important for maintaining sufficient quality forage and available habitat or space in caribou ranges.
Objective To review misinformation related to coronavirus disease 2019 (COVID-19) on social media during the first phase of the pandemic and to discuss ways of countering misinformation.
Methods We s e a r c h e d P u b M e d ® , S c o p u s , E m b a s e ® , P s y c I n f o a n d G o o g l e S c h o l a r d a t a b a s e s o n 5 May 2020 and 1 June 2020 for publications related to COVID-19 and social media which dealt with misinformation and which were primary empirical studies. We followed the preferred reporting items for systematic reviews and meta-analyses and the guidelines for using a measurement tool to assess systematic reviews. Evidence quality and the risk of bias of included studies were classified using the grading of recommendations assessment, development and evaluation approach. The review is registered in the international prospective register of systematic reviews (PROSPERO; CRD42020182154).
Findings We identified 22 studies for inclusion in the qualitative synthesis. The proportion of COVID-19 misinformation on social media ranged from 0.2% (413/212 846) to 28.8% (194/673) of posts. Of the 22 studies, 11 did not categorize the type of COVID-19-related misinformation, nine described specific misinformation myths and two reported sarcasm or humour related to COVID-19. Only four studies addressed the possible consequences of COVID-19-related misinformation: all reported that it led to fear or panic.
Conclusion Social media play an increasingly important role in spreading both accurate information and misinformation. The findings of this review may help health-care organizations prepare their responses to subsequent phases in the COVID–19 infodemic and to future infodemics in general.
Modern zoos are increasingly taking a leading role in emergency management and wildlife recovery. In the face of climate change and the predicted increase in frequency and magnitude of catastrophic events, zoos provide specialised expertise to assist wildlife welfare and endangered species recovery. In the 2019–2020 Australian bushfire season, now called Australia’s Black Summer, a state government-directed response was developed, assembling specialised individuals and organisations from government, non-government organisations, research institutions, and others. Here, we detail the role of Zoos Victoria staff in wildlife triage and welfare, threatened species evacuation and recovery, media and communications, and fundraising during and after the fires. We share strategies for future resilience, readiness, and the ability to mobilise quickly in catastrophic events. The development of triage protocols, emergency response kits, emergency enclosures, and expanded and new captive breeding programs is underway, as are programs for care of staff mental health and nature-based community healing for people directly affected by the fires. We hope this account of our response to one of the greatest recent threats to Australia’s biodiversity, and steps to prepare for the future will assist other zoos and wildlife organisations around the world in preparations to help wildlife before, during, and after catastrophic events.
The number of people dying in urban India due to deteriorating air quality is rising every year and very little is being done to deal with pollution in Indian cities. Pollution is a noun derived from transitive verb 'pollute', which according to Random House Dictionary of English Language means: to foul, to pollute the air, etc. An important component of air pollution which is assuming importance is the Pollution from Noise. Noise is an inescapable by product of industrial environment, which is increasing very fast with the advancement in industrialization. The Industries located in the residential areas such as the printing press, agro based industries, automobiles repairing, grinding mills, etc. are the main sources of community noise affecting public continuously living in the vicinity. In this short communication, nuisance, adverse impacts and some remedial measures of noise pollution are delineated concisely.
This article analyses the conceptual framework of brokerage at the science–policy interface as an important boundary function to support trusted and transparent government decision-making. Policymaking involves a broad range of considerations, but science advice and evidence is critical to help inform decisions. However, mechanisms for requesting and receiving advice from the scientific community are not straightforward, considering that the knowledge needed generally spans multiple disciplines of the natural and social sciences. Once evidence has been appropriately synthesized, there remains the need to ensure an effective and unbiased translation to the policy and political community. The concept of knowledge brokerage revolves around an understanding of the ontologies, cultures and languages of both the policy community and the science community, in order to effectively link the two bidirectionally. In practical terms, this means ensuring that the information needs of the former are understood, and that the type and form of information offered by the latter aligns with those needs. Ideally, knowledge brokers act at the interface between researchers/experts and decision-makers to present evidence in a way that informs policy options but does not determine policy development. Conceptually, negotiating this interface involves acknowledging that values are embedded in the scientific process and evidentiary synthesis, and in particular, in considering the inferential risks inherent in making evidence claims. Brokers are faced with navigating complex policy dynamics and balancing information asymmetries between research providers and users. Building on the conceptual analysis and examination of the nuances of brokerage observed in practice, we propose a set of guidelines to translate the concepts of brokerage to practical application.
The conservation field is experiencing a rapid increase in the amount, variety, and quality of spatial data that can help us understand species movement and landscape connectivity patterns. As interest grows in more dynamic representations of movement potential, modelers are often limited by the capacity of their analytic tools to handle these datasets. Technology developments in software and high-performance computing are rapidly emerging in many fields, but uptake within conservation may lag, as our tools or our choice of computing language can constrain our ability to keep pace. We recently updated Circuitscape, a widely used connectivity analysis tool developed by Brad McRae and Viral Shah, by implementing it in Julia, a high-performance computing language. In this initial re-code (Circuitscape 5.0) and later updates, we improved computational efficiency and parallelism, achieving major speed improvements, and enabling assessments across larger extents or with higher resolution data. Here, we reflect on the benefits to conservation of strengthening collaborations with computer scientists, and extract examples from a collection of 572 Circuitscape applications to illustrate how through a decade of repeated investment in the software, applications have been many, varied, and increasingly dynamic. Beyond empowering continued innovations in dynamic connectivity, we expect that faster run times will play an important role in facilitating co-production of connectivity assessments with stakeholders, increasing the likelihood that connectivity science will be incorporated in land use decisions.
Abstract Negative interactions between humans and wildlife create one of the greatest threats to biodiversity conservation. When wild animals damage the crops in agricultural fields, subsistence farmers suffer food insecurity and economic instability. Animals can be killed or injured during these interactions, and communities may develop negative feelings about conservation. To address conservation concerns, projects should look at both sides of these interactions. A Participatory Action Research approach allows researchers and community members to work collaboratively to investigate and take action in response to this issue. Our team developed a community project to determine residents' perceptions of the benefits and costs of living around Kibale National Park, Uganda, and to implement changes to mitigate those costs. During our initial survey in 2015, we found that over 80% of our 114 respondents were subsistence farmers with no other source of income. All respondents felt that crop damage by wild animals was the biggest problem with living near the park, and they had negative feelings about the park and animals. Thus, we worked with project participants to establish the following land‐use changes throughout 2016 and 2017: (a) planting garlic as a cash crop, (b) planting tea as a buffer crop, (c) building beehive fences, and (d) maintaining a trench around the boundary of the park. Through monthly surveys, we assessed the success of these changes on reducing crop damage and improving conservation initiatives. Compliance with land‐use changes was significantly associated with a reduction in the events of crop damage, which has implications for economic stability and an individual's attitude about conservation. This project provides guidelines for using Participatory Action Research methods to develop sustainable interventions to improve human‐wildlife interactions.
The COVID-19 pandemic is a wake-up call for leaders of the North American veterinary profession. Veterinary professionals constitute an invaluable workforce capable of delivering public services essential to weathering the current pandemic and preventing future pandemics. Yet North American veterinary professionals are often underutilized in efforts that could maximize their contributions to public health and research. Misguided public perception about the utility of the profession might hinder One Health partnerships between veterinary professionals and diverse collaborators. Society in general demands that leadership across several levels of the profession expand and diversify efforts aimed at greater public service while preserving societal benefits stemming from companion animal care. The pandemic's most deeply rooted effects could lie in its potential degradation of global food security, which can be better preserved if more veterinarians embrace their public health foundations. The pandemic is an opportunity and obligation for change. Failing to seize this moment could undermine public health and global security for generations.
Lyme disease, the most prevalent vector-borne disease in North America, is increasing in incidence and geographic distribution as the tick vector, Ixodes scapularis , spreads to new regions. We re-construct the spatial-temporal invasion of the tick and human disease in the Midwestern US, a major focus of Lyme disease transmission, from 1967 to 2018, to analyse the influence of spatial factors on the geographic spread. A regression model indicates that three spatial factors—proximity to a previously invaded county, forest cover and adjacency to a river—collectively predict tick occurrence. Validation of the predictive capability of this model correctly predicts counties invaded or uninvaded with 90.6% and 98.5% accuracy, respectively. Reported incidence increases in counties after the first report of the tick; based on this modelled relationship, we identify 31 counties where we suspect I. scapularis already occurs yet remains undetected. Finally, we apply the model to forecast tick establishment by 2021 and predict 42 additional counties where I. scapularis will probably be detected based upon historical drivers of geographic spread. Our findings leverage resources dedicated to tick and human disease reporting and provide the opportunity to take proactive steps (e.g. educational efforts) to prevent and limit transmission in areas of future geographic spread.
In their recent paper, Lavers et al. 2019 measured blood chemistry parameters in fledgling seabirds, finding a link between ingested plastic and growth, calcium, uric acid, and cholesterol. The manuscript suggests varied toxicological interpretations and concluded that superficially healthy animals may still experience negative health consequences of ingesting plastic debris: an influential message with dire consequences for wildlife globally. While well intended, we posit that the interpretations reveal confounding and confirmation bias and highlight a growing trend within the field of plastic pollution
and wildlife impacts. By evaluating recent publications, we provide a framework for assessing confounding and biases in plastic and wildlife research, and we reinterpret Lavers et al.’s results to suggest a nutrition explanation
Because it is only possible to test chemicals for effects on a restricted range of species and exposure scenarios, ecotoxicologists are faced with a significant challenge of how to translate the measurements in model species into predictions of impacts for the wider range of species in ecosystems. Because of this challenge, within ecotoxicology there is no more fundamental aspect than to understand the nature of the traits that determine sensitivity. To account for the uncertainties of species extrapolations in risk assessment, “safety factors” or species sensitivity distributions are commonly used. While valuable as pragmatic tools, these approaches have no mechanistic grounding. Here we highlight how mechanistic information that is increasingly available for a range of traits can be used to understand and potentially predict species sensitivity to chemicals. We review current knowledge on how toxicokinetic, toxicodynamic, physiological, and ecological traits contribute to differences in sensitivity. We go on to discuss how this information is being used to make predictions of sensitivity using correlative and trait-based approaches, including comparisons of target receptor orthologs. Finally, we discuss how the emerging knowledge and associated tools can be used to enhance theoretical and applied ecotoxicological research through improvements in mechanistic modeling, predictive ecotoxicology, species sensitivity distribution development, mixture toxicity assessment, chemical design, biotechnology application and mechanistically informed monitoring.
The Rocky Mountain ridged mussel ( Gonidea angulata ) is a bivalve species whose Canadian range is limited to the Okanagan Valley, British Columbia. In 2019, conflicts between habitat protection for the mussel and potential habitat alteration to control the invasive Eurasian watermilfoil ( Myriophyllum spicatum ) (milfoil), led to a decision to maintain the status of the mussels as Special Concern under Canada’s Species at Risk Act (SARA) rather than classify it as Endangered. Milfoil control can cause direct mortality and/or burial of the mussels, but there had been no systematic study of the impacts of milfoil control on mussel beds. The purpose of this study was to address knowledge gaps by delineating known mussel beds and potential overlap with milfoil to provide information for management decisions that balance the needs of native species protection and invasive species control. Rocky Mountain ridged mussels in three reference locations were enumerated using snorkel surveys. The presence and distribution of milfoil was documented in relation to five sites within these three locations. Milfoil was encroaching on one site, causing some changes to the substrate. At other sites, the differences in the depth and distribution of the mussel and the milfoil could allow milfoil control without damaging the mussel beds. It is recommended that, before milfoil removal near known mussel beds be undertaken, a detailed site evaluation be conducted to determine potential impacts. This study suggests presumed impediments to co-managing the mussels and controlling an invasive species should not preclude classifying the mussels as Endangered and affording protections under SARA.
Wildlife health is of emerging relevance for conservation, human health, and domestic animal health. Increased research on wildlife health problems has not been accompanied by a relative increase in effective solutions. Translational research was developed in human health to overcome blocks impeding the development of solutions out of basic research, and a translational research framework is proposed to overcome the same barriers in wildlife health. This framework has four translational phases: problem definition, potential solution development, efficacious solution development, and effective solution development. Implementation of translational research will require a restructuring of the wildlife health research enterprise with a shift, supported by funding sources and journals, to solutions-focused research including later translational phases, the creation of more deeply integrated multidisciplinary and interdisciplinary teams incorporating better representation from human social sciences, and the inclusion of end user and stakeholder participation in all phases of research.
Eco-anxiety and climate anxiety are widely discussed in contemporary media and are subjects of growing research interest. However, there is a lack of research about the definitions and variations of these phenomena. This article analyzes various views of eco-anxiety from a wide range of disciplines. Insights from various anxiety theories are used to discuss empirical studies about forms of eco-anxiety. The article points out that uncertainty, unpredictability, and uncontrollability seem to be important factors in eco-anxiety. Most forms of eco-anxiety appear to be non-clinical, but cases of "pathological" eco-anxiety are also discussed. Other relevant terms and phenomena are scrutinized, such as ecological grief, solastalgia, and ecological trauma. The relationship between studies on eco-anxiety and research about ecological emotions and affect is probed. Eco-anxiety is found to be closely connected to fear and worry, but several disciplines include discussion of its character as existential anxiety. Psychosocial and sociological perspectives point out that social dynamics shape forms of eco-anxiety in profound ways. While paralyzing forms of eco-anxiety emerge as a problem, it is noted that eco-anxiety manifests itself also as "practical anxiety", which leads to gathering of new information and reassessment of behavior options. This variety of forms of eco-anxiety should be taken into account in healthcare and public discussion.
Human‐wildlife interactions, including human‐wildlife conflict, are increasingly common as expanding urbanization worldwide creates more opportunities for people to encounter wildlife. Wildlife‐vehicle collisions, zoonotic disease transmission, property damage, and physical attacks to people or their pets have negative consequences for both people and wildlife, underscoring the need for comprehensive strategies that mitigate and prevent conflict altogether. Management techniques often aim to deter, relocate, or remove individual organisms, all of which may present a significant selective force in both urban and non‐urban systems. Management‐induced selection may significantly affect the adaptive or non‐adaptive evolutionary processes of urban populations, yet few studies explicate the links among conflict, wildlife management, and urban evolution. Moreover, the intensity of conflict management can vary considerably by taxon, public perception, policy, religious and cultural beliefs, and geographic region, which underscores the complexity of developing flexible tools to reduce conflict. Here, we present a cross‐disciplinary perspective that integrates human‐wildlife conflict, wildlife management, and urban evolution to address how social‐ecological processes drive wildlife adaptation in cities. We emphasize that variance in implemented management actions shape the strength and rate of phenotypic and evolutionary change. We also consider how specific management strategies either promote genetic or plastic changes, and how leveraging those biological inferences could help optimize management actions while minimizing conflict. Investigating human‐wildlife conflict as an evolutionary phenomenon may provide insights into how conflict arises and how management plays a critical role in shaping urban wildlife phenotypes.
Health impacts of climate change are now inevitable. The objective of this study was to see if animal health climate change adaptation was a subject of scholarly inquiry, advice, or discussion and if there was an evidence base from which to make adaptation recommendations. A scoping review of English-language literature over the past 10 years was undertaken and the top findings related to animal health adaptation and climate change were inventoried on Google. Documents found in the search focussed predominantly on hypothesizing what hazards might occur with climate change, describing their spread or proposing possible impacts. Scant evidence was found of scholarship related to sustainable animal health climate change adaptation planning or action. Investment and attention to adaptation planning and research are needed to increase confidence in climate change recommendations in the face of continuing uncertainty about the breadth of effects on animal health and the best actions to take in preparing and responding to them.
Background: Failed attempts to improve the delivery of healthcare to communities show distinct flaws that have a higher impact during a major incident or disaster (MID). This study evaluates the concept of surge capacity, which intends to achieve a balance between the needs and resources in affected areas by providing staff, stuff, structure, and system.
Methods: A systematic literature review was performed according to the PRISMA statement and by using PubMed, Scopus, and Google Scholar, and related keywords.
Results: There were limited publications about flexible surge capacity (FSC). However, the sum of data obtained indicated the need for flexibility in expanding major incidents or disasters, demanding new resources, which may neither be available on time nor reachable due to infrastructural damage.
Conclusion: FSC is a novel concept based on international guidelines. It refers to the extra and adjustable human and material resources that can be mobilized by activating nonprofessional but educated staff and different but accepted facilities in a fast, smooth, and productive way. Public health and public education play an essential role in obtaining such flexibility.
We review the economic channels by which the COVID-19 pandemic and subsequent policy responses may affect wildlife and biodiversity. The pandemic is put in the context of more than 5,000 disease outbreaks, natural disasters, recessions and armed conflicts in a sample of 21 high biodiversity countries. The most salient feature of the pandemic is its creation of multiple income shocks to rural and coastal households in biodiverse countries, correlated across sectors of activities and spatially. Various research and policy opportunities and challenges are explored .
Urbanization has a tremendous impact on the environment from landscape features to distribution of food resources. Such drastic environmental changes can result in community, population, and individual differences between urban and non-urban animals. Urbanization has been associated with differential mortality and reproduction and therefore, differences in age structure may also be expected across urban gradients. Additionally, many traits studied along urban gradients, such as morphology, can also differ across age classes, and as such, age is an important factor to consider. Despite this, differences in age structure along urbanization gradients have only rarely been examined. Here, we use black-capped chickadee (Poecile atricapillus) age, morphological, and feeder visitation data to address whether age structure, morphology, and age-related winter survival differ across a gradient of urban land use in and around Ottawa, ON. We test the hypothesis that urbanization is associated with higher proportions of juveniles, because of an increased exploratory tendency by juveniles against the hypothesis that urbanization favors higher proportions of adults because of a slower pace of life. We further hypothesize that urban chickadees will be smaller than non-urban ones, because anthropogenic environments will attract both younger and worse quality individuals. We found that urban environments were associated with significantly higher proportions of first year individuals and these proportions remained stable from late fall through all of winter. We did not, however, find evidence that age related differences explained variation in morphology. Instead variation in morphology was small and inconsistently associated with both urbanization and age. The results stand in contrast to results for two species of European birds. The present study calls for using broadly available but under-exploited data to better understand urbanization-related differences in age structure and its implications for population-level processes such as disease transmission and information flow.
Purpose: On April 26, 1986 reactor 4 at the Chernobyl power plant underwent a catastrophic failure leading to core explosions and open-air fires. On March 11, 2011, a combination of earthquake and tsunami led to a similar disaster at the Fukushima Daiichi power plant. In both cases radioactive isotopes were released and contaminated the air, soil and water in a substantial area around the power plants. Humans were evacuated from the immediate regions but the wildlife stayed and continued to be affected by the ongoing high radiation exposure initially and later decayed amounts of fallout dusts with time. In this review, we will examine the significant effects of the increased radiation on vegetation, insects, fish, birds and mammals.
Conclusions: The initial intense radiation in these areas has gradually begun to decrease but still remains high. Adaptation to radiation is evident and the ecosystems have dynamically changed from the periods immediately after the accidents to the present day. Understanding the molecular mechanisms that allow the adaptation and recovery of wildlife to chronic radiation challenges would aid in future attempts at ecosystem remediation in the wake of such incidents.
The Covid-19 pandemic presents the profoundest public health and economic crisis of our times. The seemingly impossible has happened: borders have closed, nations have locked down, and individuals have socially isolated for the collective good. We find ourselves involved in an unprecedented social experiment. This living laboratory is ripe for sociological analysis. In this introductory article, we provide a broad sociology of Covid-19, paying attention to the production of pandemics and the creation of vulnerabilities. We acknowledge the dystopian elements of the pandemic: it will provide opportunities for ‘disaster capitalists’ to profit, it will enhance certain forms of surveillance, and it will impact some constituencies far more negatively than others (here we pay particular attention to the pandemic’s gendered consequences). Yet there are also resources for hope. We are witnessing altruistic acts the world over, as mutual aid groups form to render assistance where needed. Notions of welfare reform, progressive taxation, nationalisation and universal basic income now seem more politically palatable. Some even predict the imminent demise of neoliberalism. While this may be too hopeful, reactions to the pandemic thus far do at least demonstrate that other ways of living are within our grasp. As Arundhati Roy has said: the virus is a portal, a gateway between one world and the next.
The SARS-CoV-2 virus and COVID-19 illness are driving a global crisis. Governments have responded by restricting human movement, which has reduced economic activity. These changes may benefit biodiversity conservation in some ways, but in Africa, we contend that the net conservation impacts of COVID-19 will be strongly negative. Here, we describe how the crisis creates a perfect storm of reduced funding, restrictions on the operations of conservation agencies, and elevated human threats to nature. We identify the immediate steps necessary to address these challenges and support ongoing conservation efforts. We then highlight systemic flaws in contemporary conservation and identify opportunities to restructure for greater resilience. Finally, we emphasise the critical importance of conserving habitat and regulating unsafe wildlife trade practices to reduce the risk of future pandemics.
There is a growing interest in One Health, reflected by the rising number of publications relating to One Health literature, but also through zoonotic disease outbreaks becoming more frequent, such as Ebola, Zika virus and COVID-19.
This paper uses bibliometric analysis to explore the state of One Health in academic literature, to visualise the characteristics and trends within the field through a network analysis of citation patterns and bibliographic links. The analysis focuses on publication trends, co-citation network of scientific journals, co-citation network of authors, and co-occurrence of keywords.
The bibliometric analysis showed an increasing interest for One Health in academic research. However, it revealed some thematic and disciplinary shortcomings, in particular with respect to the inclusion of environmental themes and social science insights pertaining to the implementation of One Health policies. The analysis indicated that there is a need for more applicable approaches to strengthen intersectoral collaboration and knowledge sharing. Silos between the disciplines of human medicine, veterinary medicine and environment still persist. Engaging researchers with different expertise and disciplinary backgrounds will facilitate a more comprehensive perspective where the human-animal-environment interface is not researched as separate entities but as a coherent whole. Further, journals dedicated to One Health or interdisciplinary research provide scholars the possibility to publish multifaceted research. These journals are uniquely positioned to bridge between fields, strengthen interdisciplinary research and create room for social science approaches alongside of medical and natural sciences.
The COVID-19 pandemic represents a massive global health crisis. Because the crisis requires large-scale behaviour change and places significant psychological burdens on individuals, insights from the social and behavioural sciences can be used to help align human behaviour with the recommendations of epidemiologists and public health experts. Here we discuss evidence from a selection of research topics relevant to pandemics, including work on navigating threats, social and cultural influences on behaviour, science communication, moral decision-making, leadership, and stress and coping. In each section, we note the nature and quality of prior research, including uncertainty and unsettled issues. We identify several insights for effective response to the COVID-19 pandemic and highlight important gaps researchers should move quickly to fill in the coming weeks and months.
Amazonian biodiversity is increasingly threatened due to the weakening of policies for combating deforestation, especially in Brazil. Loss of animal and plant species, many not yet known to science, is just one among many negative consequences of Amazon deforestation. Deforestation affects indigenous communities, riverside as well as urban populations, and even planetary health. Amazonia has a prominent role in regulating the Earth's climate, with forest loss contributing to rising regional and global temperatures and intensification of extreme weather events. These climatic conditions are important drivers of emerging infectious diseases, and activities associated with deforestation contribute to the spread of disease vectors. This review presents the main impacts of Amazon deforestation on infectious-disease dynamics and public health from a One Health perspective. Because Brazil holds the largest area of Amazon rainforest, emphasis is given to the Brazilian scenario. Finally, potential solutions to mitigate deforestation and emerging infectious diseases are presented from the perspectives of researchers in different fields.
As a consequence of increasing human-wildlife encounters, the associated potential for human-wildlife conflict rises. The dependency of conservation management actions on the acceptance or even the participation of people requires modern conservation strategies that take the human dimension of wildlife management into account. First of all, conservationists therefore need to understand how people perceive wildlife. In the present study we examined how wildlife perception varies with people’s socio-demographic backgrounds in terms of age, gender and education as well as the settlement structure of people’s living environment and their general life satisfaction, using the red fox (Vulpes vulpes) as a model species. We used an interview-based survey of 2,646 participants, representative for the German population, for investigating their knowledge about, risk perception of, and attitude toward red foxes. We found a negative correlation between age and the risks perceived regarding foxes. Moreover, men held a more positive attitude and perceived less risk than women. Higher education was also associated with lower risk perception and a more positive attitude. The results further indicated that people who live in rural areas perceived higher risks regarding foxes and showed a less positive attitude than people in urban or suburban areas. Finally, people who perceived higher risks and held a less positive attitude supported lethal population management actions more often. However, we also found that perceived risks decreased with participants’ general life satisfaction. Hence, wildlife perception is affected by various factors. Understanding the factors affecting wildlife perception is crucial for environmental communication and for fostering acceptance of conservation measures to improve conservation strategies.
Today, it is increasingly recognized that air pollution hurts human health. Consequently, efficient mitigation strategies need to be implemented for substantial environmental and health co-benefits. A valid approach to reducing the air pollution effects on the environment and human health is proposed. Specific guidelines have been elucidated by differentiating them on the base of the final stakeholders (citizens, enterprises, and public authorities), of the emission sources (transport, household energy, industry, and energy generation sector, agriculture, and shipping area), and of the field of implementation (urban and extra-urban context). This paper can provide useful information for governments for the implementation of a strategic plan focused on emphasizing multi-pollutant emission reductions and overall air pollution-related risk.
Microbial communities in the gastrointestinal tract influence many aspects of host health, including metabolism and susceptibility to pathogen colonization. These relationships and the environmental and individual factors that drive them are relatively unexplored for free-living wildlife. We quantified the relationships between urban habitat use, diet, and age with microbiome composition and diversity for 82 American white ibises (Eudocimus albus) captured along an urban gradient in south Florida and tested whether gut microbial diversity was associated with Salmonella enterica prevalence. Shifts in community composition were significantly associated with urban land cover and, to a lesser extent, diets higher in provisioned food. The diversity of genera was negatively associated with community composition associated with urban land cover, positively associated with age class, and negatively associated with Salmonella shedding. Our results suggest that shifts in both habitat use and diet for urban birds significantly alter gut microbial composition and diversity in ways that may influence health and pathogen susceptibility as species adapt to urban habitats.
Globally, protected areas are being established to protect biodiversity and to promote ecosystem resilience. The typical spatial conservation planning process leading to the creation of these protected areas focuses on representation and replication of ecological features, often using decision support tools such as Marxan. Yet, despite the important role ecological connectivity has in metapopulation persistence and resilience, Marxan currently requires manual input or specialized scripts to explicitly consider connectivity.
‘Marxan Connect’ is a new open source, open access Graphical User Interface (GUI) tool designed to assist conservation planners with the appropriate use of data on ecological connectivity in protected area network planning.
Marxan Connect can facilitate the use of estimates of demographic connectivity (e.g. derived from animal tracking data, dispersal models, or genetic tools) or structural landscape connectivity (e.g. isolation by resistance). This is accomplished by calculating metapopulation‐relevant connectivity metrics (e.g. eigenvector centrality) and treating those as conservation features or by including the connectivity data as a spatial dependency amongst sites in the prioritization process.
Marxan Connect allows a wide group of users to incorporate directional ecological connectivity into conservation planning with Marxan. The solutions provided by Marxan Connect, combined with ecologically relevant post‐hoc testing, are more likely to support persistent and resilient metapopulations (e.g. fish stocks) and provide better protection for biodiversity.
Growing evidence suggests that multiple wildlife species can be infected with peste des petits ruminants virus (PPRV), with important consequences for the potential maintenance of PPRV in communities of susceptible hosts, and the threat that PPRV may pose to the conservation of wildlife populations and resilience of ecosystems. Significant knowledge gaps in the epidemiology of PPRV across the ruminant community (wildlife and domestic), and the understanding of infection in wildlife and other atypical host species groups (e.g., camelidae, suidae, and bovinae) hinder our ability to apply necessary integrated disease control and management interventions at the wildlife-livestock interface. Similarly, knowledge gaps limit the inclusion of wildlife in the FAO/OIE Global Strategy for the Control and Eradication of PPR, and the framework of activities in the PPR Global Eradication Programme that lays the foundation for eradicating PPR through national and regional efforts. This article reports on the first international meeting on, “Controlling PPR at the livestock-wildlife interface,” held in Rome, Italy, March 27–29, 2019. A large group representing national and international institutions discussed recent advances in our understanding of PPRV in wildlife, identified knowledge gaps and research priorities, and formulated recommendations. The need for a better understanding of PPRV epidemiology at the wildlife-livestock interface to support the integration of wildlife into PPR eradication efforts was highlighted by meeting participants along with the reminder that PPR eradication and wildlife conservation need not be viewed as competing priorities, but instead constitute two requisites of healthy socio-ecological systems.
Society has become increasingly reliant on plastics since commercial production began in about 1950. Their versatility, stability, light weight, and low production costs have fueled global demand. Most plastics are initially used and discarded on land. Nonetheless, the amount of microplastics in some oceanic compartments is predicted to double by 2030. To solve this global problem, we must understand plastic composition, physical forms, uses, transport, and fragmentation into microplastics (and nanoplastics). Plastic debris/microplastics arise from land disposal, wastewater treatment, tire wear, paint failure, textile washing, and at‐sea losses. Riverine and atmospheric transport, storm water, and disasters facilitate releases. In surface waters plastics/microplastics weather, biofoul, aggregate, and sink, are ingested by organisms and redistributed by currents. Ocean sediments are likely the ultimate destination. Plastics release additives, concentrate environmental contaminants, and serve as substrates for biofilms, including exotic and pathogenic species. Microplastic abundance increases as fragment size decreases, as does the proportion of organisms capable of ingesting them. Particles <20 μm may penetrate cell membranes, exacerbating risks. Exposure can compromise feeding, metabolic processes, reproduction, and behavior. But more investigation is required to draw definitive conclusions. Human ingestion of contaminated seafood and water is a concern. Microplastics indoors present yet uncharacterized risks, magnified by the time we spend inside (>90%) and the abundance of polymeric products therein. Scientific challenges include improving microplastic sampling and characterization approaches, understanding long‐term behavior, additive bioavailability, and organismal and ecosystem health risks. Solutions include improving globally based pollution prevention, developing degradable polymers and additives, and reducing consumption/expanding plastic reuse.
In recent decades, a striking number of countries have suffered from consecutive disasters: events whose impacts overlap both spatially and temporally, while recovery is still under way. The risk of consecutive disasters will increase due to growing exposure, the interconnectedness of human society and the increased frequency and intensity of non‐tectonic hazard. This paper provides an overview of the different types of consecutive disasters, their causes and impacts. The impacts can be distinctly different from disasters occurring in isolation (both spatially and temporally) from other disasters, noting that full isolation never occurs. We use existing empirical disaster databases to show the global probabilistic occurrence for selected hazard types. Current state‐of‐the art risk assessment models and their outputs do not allow for a thorough representation and analysis of consecutive disasters. This is mainly due to the many challenges that are introduced by addressing and combining hazards of different nature, and accounting for their interactions and dynamics. Disaster risk management needs to be more holistic and co‐designed between researchers, policy makers, first responders, and companies.
Advocates for a One Health approach recognize that global health challenges require multidisciplinary collaborative efforts. While past publications have looked at interdisciplinary competency training for collaboration, few have identified the factors and conditions that enable operational One Health. Through a scoping review of the literature, a multidisciplinary team of researchers analyzed peer-reviewed publications describing multisectoral collaborations around infectious disease-related health events. The review identified 12 factors that support successful One Health collaborations and a coordinated response to health events across three levels: two individual factors (education & training and prior experience & existing relationships), four organizational factors (organizational structures, culture, human resources and, communication), and six network factors (network structures, relationships, leadership, management, available & accessible resources, political environment). The researchers also identified the stage of collaboration during which these factors were most critical, further organizing into starting condition or process-based factors. The research found that publications on multisectoral collaboration for health events do not uniformly report on successes or challenges of collaboration and rarely identify outputs or outcomes of the collaborative process. This paper proposes a common language and framework to enable more uniform reporting, implementation, and evaluation of future One Health collaborations.
Background
The governments of Guinea, Liberia, and Sierra Leone have acknowledged that weak health systems and poor coordination of efforts hampered effectiveness of the 2014–2016 Ebola outbreak response. The bitter experience of the Ebola outbreak response served as an important catalyst for increased efforts to comply with World Health Organization (WHO) International Health Regulations (IHR 2005), Performance of Veterinary Services (PVS) Pathway capacities, and Global Health Security Agenda (GHSA) goals. In November 2016, an interministerial meeting held in Dakar, Senegal, resulted in formalized commitments from the three nations to strengthen resilience to health threats by establishing a Regional Strategic Roadmap to institutionalize the One Health approach. Since then, each country has made significant progress towards establishing National One Health Platforms to coordinate health security interventions, in collaboration with international partners. This paper outlines the methodology and results of these efforts for the period June 2016–January 2019, with a specific focus on activities supported by the US Agency for International Development (USAID)-funded Preparedness & Response (P&R) project.
Objectives
In support of the West African Health Organization’s November 2016 Regional Strategic Roadmap for institutionalization of the One Health approach, the Preparedness & Response (P&R) project worked in coordination with national partners in Guinea, Liberia, and Sierra Leone to establish multisectoral, One Health coordinating mechanisms.
Methodology
The global USAID-funded P&R project was launched in 2014 to support the achievement of this objective, and began coordinating with partners in Guinea, Liberia, and Sierra Leone in 2016 to tailor its multi-step conceptual framework to fit the priorities and operating constraints of national stakeholders. Organized in phases of Collaboration (building key relationships), Formalization (defining and establishing a coordination structure), and Implementation (using newfound coordination to produce better health security outcomes), the framework features steps such as One Health sensitizations for multisectoral national stakeholders, development of One Health platform terms of reference and other operating guidelines, and application of these tools to coordination of technical assistance during outbreaks.
Results
In Guinea, Liberia, and Sierra Leone, in less than 3 yrs there has been a marked improvement in cross-sectoral coordination on health security actions. All three countries have passed legislation establishing permanent multisectoral coordination mechanisms referred to in this document as National One Health Platforms, or simply Platforms; instituted an annual mechanism for assessing capacity and performance of these platforms to lead health security actions; and have undertaken key steps towards developing and updating National Preparedness & Response Plans which truly reflect the multisectoral nature of emerging disease threats. However, multisectoral coordination is a work in progress: government stakeholders and their international partners continue to work together to further strengthen national ownership and investment in the newly established Platforms.
Conclusion and next steps
Newly established Platforms in Guinea, Liberia, and Sierra Leone offer a long-term structure for coordinating health security actions. However, given the short period of time since their formalization, they depend on continued national, regional, and international resources to build from recent progress and further improve capacity and performance. Regional programs such as the World Bank Regional Disease Surveillance Systems Enhancement (REDISSE) project are of critical importance in keeping the momentum going. The highlighted progress and outputs to date provide reasons and motivation for continued, longer-term investment in the Platforms.
Climate change due to increasing greenhouse gas (GHG) emissions is one of the most pressing issues facing society on a global scale. The growth of GHG emissions between 2000 and 2010 was higher than in each of the previous three decades, and each of the past four decades has been successively warmer than any preceding decades since 1850. Continued GHG emissions will cause further warming and changes in the climate system. Climate change affects livestock production in multiple ways, both directly and indirectly. Many of the impacts on the livestock sector result from increasing frequency and magnitude of weather and climate extremes such as droughts, flash floods, untimely rains, frost, hail and severe storms. This article describes some of the most vulnerable disaster communities in Asia, Africa, Australia, Europe and South America. It then describes the importance of meteorological information provided by national Meteorological and Hydrological Services to help Veterinary Services support sustainable management of livestock in vulnerable pastoral communities.
Forest fires and deforestation are the main threats to the Amazon forest. Extreme drought events exacerbate the impact of forest fire in the Amazon, and these drought events are predicted to become more frequent due to climate change. Fire escapes into the forest from agriculture and pasture areas. We assessed the potential drivers of deforestation and forest fires in the central Brazilian Amazon and show that over a period of 31 years (1985–2015) forest fires occurred only in years of extreme drought induced by El Niño (1997, 2009 and 2015). The association of forest fires with strong El Niños shows the vulnerability of forest to climate change. The areas deforested were closely associated with navigable rivers: 62% of the total deforestation from 2000 to 2018 was located within the 2 km of rivers. There was a notable increase in deforestation and forest fire during the 2015 El Niño in comparison to previous years. Only a small part of the forest that burned was deforested in the years following the wildfires: 7% (1997), 3% (2009) and 1.5% (2015). Forest close to roads, rivers and established deforestation is susceptible to deforestation and fire since these areas are attractive for agriculture and pasture. Indigenous land was shown to be important in protecting the forest, while rural settlement projects attracted both forest fire and deforestation. Of the total area in settlement projects, 40% was affected by forest fires and 17% was deforested. Rivers are particularly important for deforestation in this part of Amazonia, and efforts to protect forest along the rivers are therefore necessary. The ability to predict where deforestation and fires are most likely to occur is important for designing policies for preventative actions.
Ocean warming has severe impacts on coral reef ecosystems with frequent incidences of coral bleaching. In addition, eutrophication poses an increasing threat to coral reef environments and has been found to increase the vulnerability of corals to thermal bleaching. Eutrophication has accelerated in recent years with coastal nutrient loads expected to continue to increase under global change. However, the mechanisms by which nutrient pollution affects corals and coral reefs are still under debate, in particular with regard to nitrogen. The main objective of this paper is to review mechanisms by which nitrogen pollution affects coral health and corresponding strategies to reduce the impact of nitrogen pollution. Different coral species possess varying tolerance thresholds for nitrogen enrichment and corals show differential responses to enrichment with nitrate and ammonium. Nitrate assimilation increases oxidative stress in corals, promotes growth of the phototrophic symbionts in corals, and induces phosphate starvation in these symbionts, which further impairs the symbiosis. In contrast, a moderate supply of ammonium is mostly beneficial for coral development. In addition, combined nitrogen and phosphorous enrichment can indirectly compromise coral health by enhancing macroalgae growth and increasing the incidence of coral diseases caused by predation on corals. It must be realized that both levels of nutrient pollution and the stoichiometric ratios of C: N: P: Fe availabilities determine the ultimate effect of nutrients on coral health. We confirm the strategy to conserve coral reefs via coral-targeted water quality management, in particular by including a reduction of the nitrate influx and by proper management of fish stocks to facilitate healthy reef ecology.
Public health organizations have always used messaging to educate the public in an attempt to control the spread of epidemic diseases. Early efforts that relied on word-of-mouth communication and poster campaigns transitioned to radio and television as those technologies emerged, yet these forms of communication likely have become less effective in a crowded, noisy, and confrontational online environment. Over the past decade, emerging digital platforms have become sophisticated, targeted, and responsive in reaching and influencing the public.
Major perturbations in soil and water quality are factors that can negatively impact human health. In soil environments of urban areas, changes in antibiotic-resistance profiles may represent an increased risk of exposure to antibiotic-resistant bacteria via oral, dermal, or inhalation routes. We studied the perturbation of antibiotic-resistance profiles and microbial communities in soils following a major flooding event in Houston, Texas, caused by Hurricane Harvey. The main objective of this study was to examine the presence of targeted antibiotic-resistance genes and changes in the diversity of microbial communities in soils a short time (3–5 months) and a long time (18 months) after the catastrophic flooding event. Using polymerase chain reaction, we surveyed fourteen antibiotic-resistance elements: intI1, intI2, sul1, sul2, tet(A) to (E), tet(M), tet(O), tet(W), tet(X), and blaCMY-2. The number of antibiotic-resistance genes detected were higher in short-time samples compared to samples taken a long time after flooding. From all the genes surveyed, only tet(E), blaCMY-2, and intI1 were prevalent in short-time samples but not observed in long-time samples; thus, we propose these genes as indicators of exogenous antibiotic resistance in the soils. Sequencing of the V3-V4 region of the bacterial 16S rRNA gene was used to find that flooding may have affected bacterial community diversity, enhanced differences among bacterial lineages profiles, and affected the relative abundance of Actinobacteria, Verrucomicrobia, and Gemmatimonadetes. A major conclusion of this study is that antibiotic resistance profiles of soil bacteria are impacted by urban flooding events such that they may pose an enhanced risk of exposure for up to three to five months following the hurricane. The occurrence of targeted antibiotic-resistance elements decreased eighteen months after the hurricane indicating a reduction of the risk of exposure long time after Harvey.
Planetary urbanization exacerbates the spread of infectious disease and the emergence of pandemics. As COVID-19 cases continue to swell in cities around the world, the pandemic has visibilized urban health inequities. In the Global North, emerging trends show that lower income residents are often at greater risk for infection and death due to COVID-19, due in part to inequitable living, working and environmental conditions. We explore the underlying causes and potential long-term implications of the health inequities exemplified by outbreaks of COVID-19 in the context of evolving patterns of urban development, drawing from theories of urban environmental justice and gentrification.
The lockdown response to coronavirus disease 2019 (COVID-19) has caused an unprecedented reduction in global economic and transport activity. We test the hypothesis that this has reduced tropospheric and ground-level air pollution concentrations, using satellite data and a network of >10,000 air quality stations. After accounting for the effects of meteorological variability, we find declines in the population-weighted concentration of ground-level nitrogen dioxide (NO 2 : 60% with 95% CI 48 to 72%), and fine particulate matter (PM 2.5 : 31%; 95% CI: 17 to 45%), with marginal increases in ozone (O 3 : 4%; 95% CI: −2 to 10%) in 34 countries during lockdown dates up until 15 May. Except for ozone, satellite measurements of the troposphere indicate much smaller reductions, highlighting the spatial variability of pollutant anomalies attributable to complex NO x chemistry and long-distance transport of fine particulate matter with a diameter less than 2.5 µm (PM 2.5 ). By leveraging Google and Apple mobility data, we find empirical evidence for a link between global vehicle transportation declines and the reduction of ambient NO 2 exposure. While the state of global lockdown is not sustainable, these findings allude to the potential for mitigating public health risk by reducing “business as usual” air pollutant emissions from economic activities.

Imposex is a condition in which females of dioecious marine snails develop rudimentary male characteristics. It is caused by tributyltin (TBT) used as an antifoulant in vessel paints since the late 1960s. Following the 2008 international ban on TBT, a decreasing rate of imposex has been observed worldwide. In Western Australia, imposex surveys of the whelk Thais orbita up to 2011 in the Perth metropolitan area suggested a decreasing trend but a significant recovery has not been confirmed. Collection of T. orbita from 11 sites in 2019 demonstrated a virtually complete recovery from imposex. Although it is generally accepted that male snails are not affected by TBT, the historical data set allowed confirmation that the male penis is of similar size in T. orbita collected at heavily affected sites and at relatively unaffected sites. Similarly, imposexed female snails had similar shell lengths to female snails at non-impacted sites.
Climate change poses a significant threat to humanity by intensifying multiple hazards. South Pacific Island countries (SPICs) are affected and face a dire challenge to survival. Sea level rise is reducing the already limited land for human and animal habitation. Tropical cyclones and droughts are having devastating effects on the lives of humans and animals. Tropical cyclone Winston, for example, destroyed infrastructure for humans and animals in some parts of Fiji, and infectious diseases are spreading to regions where they are not commonly seen following cyclones and floods. Likewise, climate change is making droughts worse. Droughts are destroying crops and pasturelands and making freshwater unavailable for human and animal populations in the Solomon Islands and Tuvalu. There is an urgent need to ascertain the best approaches to tackle the events, which are already happening. Short-term changes can be managed at local levels through public awareness campaigns, understanding the weather patterns to prepare for disasters, reclaiming land, improving livestock breeds, introducing zoos and wildlife sanctuaries and inventing economically feasible technologies to harvest water. Long-term solutions depend on the implementation of international agreements, international aid and collective effort.
