Article
Full-text available
Understanding pathways to environmental sustainability in tropical regions is a priority for conservation and development policies. Because drivers of environmental degradation often occur simultaneously, a holistic approach is needed. We analyzed environmental degradation on demarcated indigenous lands in Guyana, using a spatially explicit, agent-...
Article
Full-text available
Sea-level rise (SLR) will greatly alter littoral ecosystems, causing habitat change and loss for coastal species. Habitat loss is widely used as a measurement of the risk of extinction, but because many coastal species are migratory, the impact of habitat loss will depend not only on its extent, but also on where it occurs. Here, we develop a novel...
Article
Full-text available
Research in systematic conservation planning has focused heavily on biological considerations, even though a growing number of studies demonstrate that integrating economic costs into the planning process markedly increases the efficiency of resulting plans. At the global scale, the availability of biodiversity maps is increasing, but analogous map...
Article
Full-text available
Despite important implications for human health, distribution, abundance and behaviour of most medically‐relevant snakes remain poorly understood. Such data deficiencies hamper efforts to characterise the causal pathways of snakebite envenoming and to prioritise management options in the areas at greatest risk. We estimated the spatial patterns of...
Preprint
Full-text available
Snakebite is the only WHO-listed, not infectious neglected tropical disease (NTD), although its eco-epidemiology is similar to that of zoonotic infections: envenoming occurs after a vertebrate host contacts a human. Accordingly, snakebite risk represents the interaction between snake and human factors, but their quantification has been limited by d...
Article
Dryland agriculture has extensive impacts on surrounding ecosystems through its unintentional provision of food and water resources to local wildlife. We analyzed the response of a predator community of jackals, wolves and foxes to land-management choices, and how that response in turn affects native gazelles and Acacia vegetation in the Arava Vall...
Article
Full-text available
Background Snakebite incidence shows both spatial and temporal variation. However, no study has evaluated spatiotemporal patterns of snakebites across a country or region in detail. We used a nationally representative population sample to evaluate spatiotemporal patterns of snakebite in Sri Lanka. Methodology We conducted a community-based cross-s...
Article
Full-text available
Snakebite envenoming is a set of intoxication diseases that disproportionately affect people of poor socioeconomic backgrounds in tropical countries. As it is highly dependent on the environment its burden is expected to shift spatially with global anthropogenic environmental (climate, land use) and demographic change. The mechanisms underlying the...
Article
Full-text available
The rapid pace of current global warming lead to the advancement of spring migration in the majority of long-distance migratory bird species. While data on arrival timing to breeding grounds in Europe is plentiful, information from the African departure sites are scarce. Here we analysed changes in arrival timing at a stopover site in Israel and an...
Article
Full-text available
Snakebite causes more than 1.8 million envenoming cases annually and is a major cause of death in the tropics especially for poor farmers. While both social and ecological factors influence the chance encounter between snakes and people, the spatio-temporal processes underlying snakebites remain poorly explored. Previous research has heavily focuse...
Article
Full-text available
Vector-borne diseases remain a major contributor to the global burden of disease, while climate change is expected to exacerbate their risk. Characterising vector development rate and its spatio-temporal variation under climate change is central to assessing the changing basis of human disease risk. We develop a mechanistic phenology model and appl...
Article
Full-text available
While anthropogenic land‐use changes threaten wildlife globally, some species take advantage of such changes and disperse into urban areas. The wildlife in urban areas often promotes conflicts with humans, notably when the animals are associated with the spread of zoonotic diseases. In Israel, current urban invasion of rock hyraxes (Procavia capens...
Article
Full-text available
Background Health outcomes and causality are usually assessed with individual level sociodemographic variables. Studies that consider only individual-level variables can suffer from residual confounding. This can result in individual variables that are unrelated to risk behaving as proxies for uncaptured information. There is a scarcity of literatu...
Article
Full-text available
Migratory species can travel tens of thousands of kilometers each year, spending different parts of their annual cycle in geographically distinct locations. Understanding the drivers of population change is vital for conserving migratory species, yet the challenge of collecting data over entire geographic ranges has hindered attempts to identify th...
Article
Full-text available
Terrestrial, freshwater, and marine ecosystems are connected via multiple biophysical and ecological processes. Identifying and quantifying links among ecosystems is necessary for the uptake of integrated conservation actions across realms. Such actions are particularly important for species using habitats in more than one realm during their daily...
Article
Species and ecosystems worldwide continue to decline and disappear in spite of decades of investment in conservation efforts. Systematic conservation planning (SCP) is a field of study designed to improve conservation programs by identifying land configurations that, if protected, would most efficiently sustain biodiversity. Despite contributing to...

National conservation conferences provide benefits not currently served by meetings at other levels
Article
Historically, protected areas were often designated using criteria other than biodiversity conservation as the primary objective. With the emergence of the science of systematic conservation planning, the designation of new protected areas is increasingly made with explicit conservation objectives in mind. However, assessments of the performance of...
Article
Implementation of adaptation actions to protect biodiversity is limited by uncertainty about the future. One reason for this is the fear of making the wrong decisions caused by the myriad future scenarios presented to decision-makers. We propose an adaptive management (AM) method for optimally managing a population under uncertain and changing habi...
Article
Accurate estimations of carbon stocks across large tracts of tropical forests are key for participation in programs promoting avoided deforestation and carbon sequestration, such as the UN REDD+ framework. Trained local technicians can provide such data, and this, combined with satellite imagery, allows robust carbon stock estimation across vegetat...
Conference Paper
Background/Question/Methods Citizen science has the capacity to enable the collection of ecological data at large temporal and spatial scales that could otherwise be unrealistic if only experts were used. This has the potential to contribute effectively to large-scale monitoring, reporting and verification (MRV) programmes such as REDD+, critical...
Article
Every year, millions of migratory shorebirds fly through the East Asian-Australasian Flyway between their arctic breeding grounds and Australasia. This flyway includes numerous coastal wetlands in Asia and the Pacific that are used as stopover sites where birds rest and feed. Loss of a few important stopover sites through sea-level rise (SLR) could...
Article
Full-text available
Governments have agreed to expand the global protected area network from 13% to 17% of the world's land surface by 2020 (Aichi target 11) and to prevent the further loss of known threatened species (Aichi target 12). These targets are interdependent, as protected areas can stem biodiversity loss when strategically located and effectively managed. H...
Article
Full-text available
Identification of spatial gradients in ecosystem vulnerability to global climate change and local stressors is an important step in the formulation and implementation of appropriate countermeasures. Here we build on recent work to map ecoregional exposure to future climate, using an envelope-based gauge of future climate stability—defined as a meas...
Conference Paper
Full-text available
The best practice method for managing ecological systems under uncertainty is adaptive management (AM), an iterative process of reducing uncertainty while simultaneously optimizing a management objective. Existing solution methods used for AM problems assume that the system dynamics are stationary, i.e., described by one of a set of pre-defined mod...
Article
Full-text available
The behaviour of traders in a stock market is influenced by their attitude toward the risk of the security. In this research the internal model of the risk-averse and the risk-loving trader is proposed in the context of the artificial market. This model is based on the ideas of the expected utility hypothesis. It is important to model the differenc...
Article
Full-text available
Climate change is impacting species and ecosystems globally. Many existing templates to identify the most important areas to conserve terrestrial biodiversity at the global scale neglect the future impacts of climate change. Unstable climatic conditions are predicted to undermine conservation investments in the future. This paper presents an approa...

April, p. 222) proposed a systematic plan for acquir-ing new protected areas in Madagascar, using extensive new species richness data, but their analy-sis did not consider the costs of acting in different regions. Costs vary substantially; omitting this important facet of conservation planning can lead to poor biodiversity outcomes. Conservation ag...
Article
Full-text available
Initiatives to reduce carbon emissions from deforestation and degradation (REDD) are providing increasing incentives for forest protection. The collateral benefits for biodiversity depend on the extent to which emissions reductions and biodiversity conservation can be achieved in the same places. Globally, we demonstrate spatial trade-offs in alloc...
