Research Ideas and Outcome

The sixth mass extinction and the ongoing biodiversity and climate crises demand urgent action from ecologists and environmental scientists (EESs). Despite their critical role in addressing these challenges, EESs face unclear professional responsibilities towards society, local communities and ecosystems. The 2024 ANdiNA workshop was held in Conguillío National Park in Chile, within Wallmapu the ancestral land of the Mapuche people. It gathered global EESs to explore the roles, obligations and accountability of professionals in this field. The discussions focused on the evolving responsibilities of EESs amidst the environmental crises, as well as the need for clearer frameworks to guide their actions. Key questions included the scope of EESs' professional activities, how their obligations should adapt during times of crisis and whether they should be held accountable for scientific mistakes that lead to negative societal outcomes. The workshop explored the potential for creating a codified framework, such as an oath or manifesto, to clarify EESs' professional responsibilities. Participants highlighted the importance of integrating financial, intellectual, ethical and institutional dimensions in defining these roles, particularly in how EESs engage with local communities and society. Emerging themes included the need for a shared framework to align EESs' actions, exemplified by the Conguillío Statement , which encourages collaboration, inclusivity and ethical engagement with communities, especially Indigenous ones. The workshop also emphasised the importance of solution-orientated, transformative research and advocacy, calling for a shift in how EESs approach their roles as agents of change. By critically reflecting on their responsibilities, the workshop provided a foundation for re-imagining the role of EESs in the face of global environmental crises, urging systemic, collaborative approaches to safeguarding both nature and humanity.

Herbal food supplements produced from medicinal and aromatic plants (MAPs) are becoming increasingly popular to complement synthetic pharmaceuticals. This category of products is regulated under more lenient food product regulations rather than the stringent rules applicable to medicines. The effectiveness and safety of these products rely on various factors, including the varying phytochemical composition of the original plant material, potential adulteration, substitution and contamination from biological and chemical sources. The SAFEMAPS scientific research project aims to provide integrated analytical solutions that enhance the compliance and quality of food supplements derived from aromatic and medicinal plants. This project seeks to improve the safe use of these products by consumers, while promoting the sustainable exploitation of plant biodiversity. Within this project, an experimental model will be developed to assess the identity, authenticity, traceability and quality of herbal food supplements. This model includes analytical solutions that integrate phytochemical and molecular genetic analyses. The proposed solutions will prioritise the needs of the food supplements industry, particularly regarding the quality and compliance of herbal products sold in Romania and across the European single market. These solutions will also tackle various aspects of the supply chain, including growers or collectors of medicinal and aromatic plants, processors, importers and final consumers.

State geological surveys create and steward valuable long-term earth and environmental science datasets and often serve as physical archives for material samples. Often funded directly through state legislatures, these agencies face varying degrees of support, nuanced regulations and public-serving missions that direct their research and day-to-day operations. Scientists at state geological surveys produce a range of outputs: datasets that may be stored internally, through an institutional repository or disseminated to broader community repositories and publications that may include both grey and peer-reviewed literature. This paper discusses a workshop held at the Kentucky Geological Survey to introduce researchers to data management, sharing and stewardship practices and to better understand obstacles to implementing such practices.

Electronic monitoring (EM) using video cameras is valuable for documenting fisheries catch and bycatch, but it remains challenging to implement in small-scale fisheries. Current barriers include high costs, technical installation needs and limited power supply on small vessels. In addition, as most EM systems on the market are difficult to quickly move between vessels, they do not allow for random data collection, which may be required to obtain reliable estimates of bycatch across a fleet. Basic EM systems available, designed for use in small-scale fisheries, are image-based, have low frame rates and are not always capable of recording in high enough video quality to identify species with high precision. The Swedish small-scale fishery consists of over 700 boats (under 12 m length), with key target species including cod, herring, sprat and flatfish. To meet monitoring requirements and to gather sufficient data for machine-learning applications, we created the HafsAuga MobileEM: a low-cost mobile multi-camera, GPS and remote data offload system for recording data on fisheries catch, bycatch and effort. It records video (up to 60 fps), is compact (~ 2 kg) and deployable in under 30 minutes. Designed to be simple to operate and install, it is modifiable and allows users to connect to a vessel's 12v power or to an internal battery to record high-quality video footage continuously for over a week. This system is ideal for use in small-scale fisheries and also well-suited to situations where fleets need to be randomly sampled by quickly moving EM systems between vessels. Here, we describe the HafsAuga MobileEM system and outline its use in Sweden, where it has been in use since 2020. To date, twenty Swedish vessels have had mobile systems mounted on them and over 1000 fishing days have been successfully recorded. The HafsAuga MobileEM provides an innovative new EM tool with potential applications in fisheries in other regions.

Wild fauna and flora are facing variable and challenging environmental disturbances. One of the animal groups that is most impacted by this, concerns pollinators. Pollinators face multiple threats, but the spread of anthropogenic chemicals (i.e. pesticides) form a major potential driver of these threats. WildPosh is a multi-actor, transdisciplinary project whose overarching mission and ambition are to significantly improve the evaluation of risk to pesticide exposure of wild pollinators, and enhance the sustainable health of pollinators and pollination services in Europe. As chemical exposure varies geographically, across cropping systems, inside the crop system and among pollinators, we will characterise exposure by doing fieldwork in 4 countries representing the four main climatic European regions, Mediterranean, Atlantic, Continental and Boreal climate in Germany, England, Estonia and Spain. We will also develop experiments in controlled conditions on different species of bees, syrphid flies, moths and butterflies, and collect in silico data on their traits and on toxicity of pesticides. With WildPosh, we aim to achieve the following objectives: 1. Determining the real-world agrochemical exposure profile of wild pollinators at landscape level, within and among sites; 2. Using integrated and controlled laboratory and semi-field experiments to characterise causal relationships between pesticides and pollinator health; 3. Building an open database on pollinator traits/distribution and chemicals to define exposure and toxicity scenarios by developing databases on ecological traits and the spatial distribution of pollinators in relation to their potential exposure to pesticide; 4. Proposing integrated systems-based risk assessment tools for risk assessment for wild pollinators; and 5. Driving policy and practice through interactive innovation, meeting the need for monitoring tools, novel and innovative screening protocols for practice and policymaker use.

In this contribution of the Hypothesis Description series, we provide an overview of one of the longest-standing hypotheses in invasion science: Darwin's naturalisation hypothesis. We present a brief summary of past definitions and propose the revised definition “high phylogenetic distance between non-native species and the recipient community increases invasion success”. This formulation follows the basic form ‘subject – relationship – object’, enabling clarity for future research and computational applications in invasion biology. We also provide formalised definitions for previous formulations of the hypothesis and identify both related and opposite hypotheses to Darwin’s naturalisation hypothesis.

The European Research Infrastructure DiSSCo (Distributed System of Scientific Collections) aims to digitally unify all European natural science assets, to ensure that collection data are easily findable, accessible, interoperable and reusable (FAIR). 170 institutions across more than 23 countries are involved in this ambitious objective of transforming a fragmented landscape of collections into an integrated knowledge base, enabling researchers to use and interconnect different collections. Research Infrastructure (hereinafter referred as to RI) cost calculation can be multifaceted and complex. DiSSCo is both a central team and a coordinated network responsible for supplying the infrastructure’s services. The RI linked costs are spread all over Europe and connect thousands of people. As the extended DiSSCo perimeter encompasses a wide range of services - from physical access, to digitisation on demand and consulting services - distributed amongst a great number of partners, cost information is spread across centralised and decentralised areas. The following article outlines the first “centralised” cost calculation exercise for DiSSCo and concludes that the DiSSCo Central Hub office would need a minimum annual budget of 1.4 million euros to be operational. This would not change between the construction and the operation phases. Furthermore, the DiSSCo Central Hub IT team would need a budget of 2.2 million euros to finalise all IT systems under the construction phase (if the construction phase lasts two years, it would cost around 1.1 million euros per year) in order to develop the digital services that will facilitate access to NSC data. The annual cost to operate these services would be around 1.2 million euros per year. This budget will evolve according to funding opportunities, the enlargement of the membership and the implementation of a business model open to new sources of income. As is often the case, research infrastructures grow over time and the more DiSSCo becomes known and recognised, the more it will attract users and the more its budget will increase. In order to calculate the RI linked costs, which are spread all over Europe, we developed a cost calculation methodology that has been distributed amongst all the 170 DiSSCo partner institutions. Twenty-seven institutions responded to the exercise. This allows for a first shared understanding on how to calculate DiSSCo related costs. It also provides the first figures on a cost-per-hour or a cost-per-service basis and it opens the door for the pricing of DiSSCo services. Finally, such a methodology also aims at guaranteeing a fair service pricing, based on the same principles and variables.

The InsectAI COST action will support insect monitoring and conservation at the national and continental scale in order to understand and counteract widespread insect declines. The Action will bring together a critical mass of researchers and stakeholders in image-based insect AI technologies to direct and drive the research agenda, build research capacity across Europe and support innovation and application. There is mounting evidence that populations of insects around the world are in sharp decline. Understanding trends in species and their drivers is key to knowing the size of the challenge, its causes and how to address it. To identify solutions that lead to sustainable biodiversity alongside economic prosperity, insect monitoring should be efficient and provide standardised and frequently updated status indicators to guide conservation actions. The EU Biodiversity Strategy 2030 identifies the critical challenge of delivering standardised information about the state of nature and image-based insect AI can contribute to this. Specifically, the EU Nature Restoration Law will likely set binding targets for the high resolution data that cameras can provide. Thus, outputs of the Action will contribute directly to EU policies implementation, where biodiversity monitoring is considered a key component. The InsectAI COST Action will organise workshops, conferences, short-term scientific missions, hackathons, design-sprints and much more, across four Working Groups. These groups will address how image-based insect AI technologies can best address Societal Needs, support innovation in Image Collection hardware, create standardised approaches for Image Processing and develop novel Data Analysis and Integration methods for turning data into actionable insights.

The European Spallation Source ERIC relies on in-kind contributions from its Members, including technical components, R&D and services, which are vital to its construction and operation. The complex nature and delivery of in-kind contributions have posed significant accounting challenges. Following a comprehensive review in collaboration with external advisors, the European Spallation Source ERIC has adopted a harmonised approach that aligns the treatment of in-kind contributions with cash contributions, enhancing transparency towards stakeholders, compliance with accounting principles and the robustness of financial reporting. The experience of the European Spallation Source ERIC in addressing these complexities offers valuable insights for other ERICs and organisations with similar scopes, promoting effective and transparent management of in-kind contributions. This commentary aims to contribute to the broader understanding of managing in-kind contributions by sharing the European Spallation Source ERIC's experience and lessons learned.

Participatory science and "amateur" participation in scientific data collection and work has been common for hundreds of years, but has become a more formalised field of practice in recent decades. The inclusion and reliance on informally trained members of the public in scientific endeavours has especially helped connect natural history collections to the general public. In recent decades, the term used to describe these participants — citizen scientists — was intended to unite formal and informal scientists as global citizens working towards a common goal. However, the term 'citizen' today has negative connotations for many members of the public and can have a polarising effect on certain individuals. Given that the nature of participatory science is to be inclusive and inviting, it is time to change this terminology. The term 'community' science has been suggested as an alternative by some practitioners and programmes. This self-awareness within the scientific community is important, but lacks impact without input from the community members potentially participating in these programmes. We addressed this knowledge gap by posing the question of term preference to groups of volunteers who have attended participatory science activities from the Field Museum of Natural History (Chicago, Illinois, USA) and the Natural History Museum of Los Angeles County (Los Angeles, California, USA) from 2019 to 2023. A majority of respondents showed a clear preference for the term 'community' over 'citizen' science. This was especially true for younger individuals and those who belong to ethnic groups other than White. This information can impact which terms are used for specific programme populations and supports community involvement in selecting terminology and in project design. We advise stopping use of the term 'citizen' in all participatory science programmes and adopting terminology that is most appropriate depending on region, research, audience and activity. Moreover, participant populations should be solicited to hear their voices.

Animal-transmitted diseases such as rabies represent a barrier to successful rewilding and threaten continued human-wildlife co-existence. In North America, population growth and human settlement expansion lead to encounters with wild mammals which have the potential to transmit rabies to domestic dogs and humans. The recent development of gene drives mediated by CRISPR-Cas9 allows for ecosystem engineering at unprecedented scales given the potential to spread new traits through wild populations with biased inheritance exceeding the pattern of classical Mendelian dominant genes. This study of a possible red fox rabies immunity gene drive project contributes a novel proposal to the existing academic conversation about suitable applications of gene drive technology in wild animal populations, such as projects to fight malaria and Lyme disease. Noting the unique characteristics of rabies, such as the dire mortality rate in humans once symptoms arise, as well as the tendency for rabid wild animals to lose their fear of humans, it appears to be a suitable target for eventual eradication via gene drive to spread immunity through wild mammal reservoir populations. Introducing heritable rabies immunity into North American red fox populations through gene drive represents a strategy to both battle rabies and adjust the ecology of (sub)urban environments. Given this review of the project's possible implementation and expected outcomes, providing inherited rabies immunity to wild red fox populations in North America via gene drive appears both feasible and sensible. Similar projects may be used to eradicate comparable infectious diseases from other wild animal populations, with likely benefits to human patients, wildlife and ecosystems.

Much of the work developed on biodiversity dynamics due to climate change focuses on large scales. Yet, we know that small scale is critical to fully understand biodiversity change, particularly for plants and small or less mobile organisms which might seek refuge in sites that keep specific microclimatic and biotic conditions dampening the effects of large-scale changes. The project BASS - Biodiversity Assessment at Small Scales - aims to explore the intricate relationships between small-scale environmental variations in space and time and biodiversity patterns. Central to our study is researching how microclimatic conditions, such as potential solar radiation, influence species occurrence, abundance, community composition and biotic interactions within a Mediterranean context. Our objectives include gaining a deeper understanding of the effects of localised environmental conditions and their change in time on biodiversity, providing critical data for an under-researched Mediterranean Biodiversity Hotspot region, and examining the dynamics of small-sized species, particularly plants and invertebrates. We have established a network of 16 fixed sampling points across the Lisbon University field station - Herdade da Ribeira Abaixo (HRA), Grândola (South Portugal): eight with high and eight with low potential solar radiation. Each of these plots will serve as a 'mesocosm' for detailed ecological studies in the next decades. This framework will support a variety of research projects each focusing on different taxa and questions, including Masters' theses, PhD dissertations and independent studies, thereby fostering a collaborative research environment. By integrating previously collected data during the last three decades with new findings, we aim to offer valuable insights into the processes underlying ecosystem functioning and change at small spatial scales. This project not only addresses fundamental ecological questions, but also contributes to sustainable landscape management and biodiversity conservation efforts.

The island of Guam’s only gymnosperm and historically one of the island’s most abundant trees, Cycas micronesica, has been devastated by high mortality due primarily to the armoured scale Aulacaspis yasumatsui. This cycad-specific scale pest invaded Guam in 2003 and, in only a few years, this pest caused over 90% mortality to maturing trees and 100% mortality to seedlings. In 2015, C. micronesica was listed under the United States Endangered Species Act. Continuous surveillance of tree mortality throughout the island showed extreme decline in health until recent surveys have demonstrated that there has been improved tree health with little evidence of leaf herbivory on some remaining trees. Suggested explanations for this observed reduction in scale herbivory include some form of resistance in the surviving trees or a biocontrol agent (or several agents) that previously existed or has been introduced unintentionally and is controlling the scale to a greater degree. A combination of resistance and biocontrol are possibly both involved. We discuss in depth these possibilities and then propose experimental approaches that will help resolve this question.

DNA collections are a valuable type of Natural Science collection, enabling the validation of past research, serving as a source for new genomic studies and supporting ex situ conservation. The DiSSCo Flanders DNA collection working group, aiming to advance and "unlock" their DNA collections, identified the need for: 1) actively sharing best practices regarding the management of DNA collections; and 2) providing guidance on how to bring theory into practice. By combining best practice examples from within the working group with available literature and brainstorming ideas, the working group co-created two outputs, referred to as: the "Challenges" and the "Key". The Challenges are a list of obstacles to DNA collection management, which shape the structure of the linked Key and can also be used to spark discussion amongst stakeholders. The Key is a tool that guides users through the maturation process of their DNA collection in a standardised way. It stimulates holistic growth, breaks down the needed work into manageable steps and helps to decide priorities during the process. Furthermore, the Key facilitates communication with both internal stakeholders and external DNA collection managers. The Key distinguishes itself from other self-assessment tools in several ways: it includes (re)investigation of the collection’s purpose and context; it is specialised for DNA collections; it delivers concrete goals linked to relevant information and shared experience; and it is inclusive, targeting all Natural Science DNA collections, regardless of their context or size.

Defined as the benefits derived from nature to humans, the Ecosystem Services (ES) concept clarifies how ecosystems contribute to human well-being. Despite its relevance, integrating this concept into decision-making processes remains a challenge. Participatory approaches have proven crucial in developing mechanisms for managing, conserving, sustainably using and valuing ES. This work aimed to analyse the perceptions of Portuguese Biosphere Reserves’ (BR) managers regarding the ES provided by these territories through a participatory workshop. During the workshop, each participant specified the most relevant ES provided by the BR. The study identified three key ES: "Cultivated terrestrial plants (including fungi, algae) grown for nutritional purposes", "Characteristics of living systems that enable scientific investigation or the creation of traditional ecological knowledge" and "Characteristics of living systems that enable education and training". Additionally, participants discussed perceived threats, opportunities and potential solutions to enhance the value of these key ES in these areas. "Climate change" and "Pollution" were identified as the most significant threats, while "Climate adaptation", "Quality of life" and "Sustainable agriculture" emerged as the main opportunities. Solutions to address threats and maximise opportunities include the establishment of a closer, systematic and articulated relationship within BR to promote sustainability and resilience. Overall, the workshop was positively evaluated and deemed productive. It was also considered a powerful tool to foster collaboration towards a more holistic promotion of BR' sustainable governance, benefitting the environment, communities and the economy.

The BioDT project, funded by the European Union Horizon Europe Programme, seeks to investigate and push the boundaries of methodological, intellectual, data, technical and relevance aspects of the digital twin (DT) approach for understanding and predicting biodiversity patterns and processes. In this special issue, we present the reasoning and goals of the project and the overall advancements made towards the development of ten prototype Digital Twins (pDTs). Based on models of ecosystems, species and biological processes, digital twins integrate diverse data sources with advanced modelling and simulation techniques to provide a comprehensive, dynamic and data-driven understanding of biodiversity. Leveraging the EuroHPC LUMI infrastructure and data and expertise from GBIF, eLTER, DiSSCo and LifeWatch ERIC research infrastructures, the project aims to develop hybrid models combining the strengths of statistical and process-based models for improved predictive capabilities. While there are specific challenges and limitations to biodiversity DTs, the pDTs of BioDT lay the foundation for model-data fusions that will offer potential benefits to a wide range of end-users, from researchers and conservation organisations to policy-makers, land managers, educators and private sector companies. By fostering global interoperability in biodiversity data and research, BioDT paves the way for future collaborative efforts in biodiversity conservation and management.

Environmental DNA (eDNA) analysis has transformed our understanding of aquatic ecosystems, but traditional methods often lack insights into organismal health. The emerging field of environmental protein (eProtein) analysis offers a novel approach to monitoring the physiological status of aquatic organisms. Recent advancements in proteomic technologies have enabled the detection and characterization of stress-responsive proteins in water samples, providing valuable insights into organismal health and environmental stressors. This perspective paper explores the potential of eProtein analysis for monitoring aquatic organism health, disease dynamics and reproductive cycles. Methodological advancements in protein extraction and mass spectrometry have enhanced the sensitivity and specificity of eProtein analysis, facilitating comprehensive molecular profiling and biomarker identification. By integrating eProtein analysis into aquaculture management and environmental monitoring, researchers can proactively manage fish health, mitigate disease outbreaks and safeguard aquatic ecosystems. Future research directions include refining extraction methods, establishing standardized protocols and leveraging interdisciplinary collaborations to maximize the potential of eProtein analysis for aquatic research and conservation.

The DSAIL-GeJuSTA Data Science Education Workshop was a joint initiative by the Centre for Data Science and Artificial Intelligence (DSAIL) and Gender Justice in STEM Research in Africa (GeJUSTA). GeJUSTA is a programme funded by the International Development Research Centre (IDRC) that is working towards increasing the representation of women in STEM. The workshop was held on 9 November 2023, during the 7th DeKUT International Conference on Science, Technology, Innovation and Entrepreneurship (STI&E) at Dedan Kimathi University of Technology (DeKUT). The conference ran from 8-10 November 2023. The event successfully convened 31 participants. The composition of the attendees was diverse, ranging from data-science educators, industry participants using data science, researchers who use data science and students in a myriad of courses, including engineering and pharmacy. The primary focus of the workshop was to have a discussion with the attendees and share practices around designing data-science curriculum, strategies for achieving gender equity in data-science education, addressing new technological challenges in education and fostering multidisciplinary approaches to data-science education. This report encapsulates the collective vision of the workshop participants, whose contributions have set the stage for progressive strides in data-science education.

Over the last decade, access to global data has become increasingly critical for research, allowing insights into diverse biological, environmental and societal questions at a macro scale. Digitisation has greatly enhanced the use of herbarium data in the analysis of species distributions and ecological niche modelling. Yet, sources on modelling and mapping methodology using open-source software is greatly lacking for beginners. We have created a replicable and thorough tutorial to visualise species occurrence data and exploratory analysis that was developed by undergraduates with broad backgrounds and levels of experience. This tutorial integrates the open-source programmes QGIS, MaxEnt and R to develop distribution maps, using bryophytes as a case study, to promote the accessibility of open-source software and remote access learning. This tutorial has already set the foundation for further research into distribution modelling of rare Illinois bryophytes to better understand the potential impact of climate change.

Brazil's National Forest Inventory (IFN), coordinated by the Brazilian Forest Service (SFB), provides essential data on the country's forest resources. The availability of IFN data, collected over more than a decade, through the National Forest Information System (SNIF), promotes transparency and facilitates access to comprehensive information about Brazilian forests. This detailed survey covers biophysical, botanical and socio-environmental aspects, as well as interviews about the use of forest resources.

Diverse actors within and outside the academic system increasingly call upon scientists to engage with the public through science communication as part of their academic work. This raises the question of how these actors' demands can and should be met in practice. At the conference on “Perspectives on science communication”, which took place on 27 May 2024, at the Museum für Naturkunde in Berlin, interested scientists and communicators from the Leibniz Association came together to reflect on the strategic development of the field of science communication. The focus was on the exchange of realistic goals, important actions and the actors responsible for the further development of the field and practice of science communication. These three topics were discussed in the context of a keynote speech and a panel discussion, as well as with regard to specific forms of interaction between science and society, including informative, dialogic and participatory formats of science communication. The discussions reveal a diversity of goals scientists can aim for, but also a multitude of action areas that need to be addressed by a number of actors to achieve these goals. Goals particularly hinted at an increasing, yet-to-be-defined quantity of communication, including contents related to informing about facts in societal debates, engaging in democratic dialogue and encouraging participation of citizens in research to increase innovation in science, but also process-related goals such as building partnerships, communicating transparently or providing support for scientists. Action areas to achieve these goals are diverse and regard strengthening recognition and reputation, supporting and protecting scientists, providing temporal and financial resources for science communication and changing researcher’s attitudes. In terms of actors, conference participants hinted at the diverse roles of different actors, focusing the discussion on actors in academia, politics and administration, civil society as well as boundary organisations such as the media as key actors to further advance the topic of science communication. This conference report elaborates the results related to these three topics and, thus, creates the basis for an in-depth discussion of the results in Germany and internationally.

The National Council for Scientific and Technological Development (CNPq) and Confap announced the launch of the 5th edition of the Protax programme aimed at supporting the advancement of human resources in biological taxonomy. The funding for the programme has been increased from R$6 million (equivalent to 1,1 million US dollars) to R$14 million ($2,5 million), making grants of up to R$400,000 ($73 thousand) per project available. However, it is important to note that the programme primarily emphasises human resources, overlooking the crucial need for funding fieldwork, which plays a vital role in taxonomic research in diverse ecosystems like the Amazon. To ensure the success of Protax, a comprehensive approach including dedicated funds for expeditions and biological collections is essential.

A network of European organisations is coordinating a workshop in New York (USA) on September 26, 2024, as part of the Science Summit 2024 at the 79th Session of the UN General Assembly (UNGA79). This network represents active communities from the fields of biodiversity, ecology, and engineering. It aims to strengthen science, technology, and innovation efforts to achieve the UN Sustainable Development Goals (SDGs). These communities, through European initiatives like the European Research Infrastructures, the European Open Science Cloud (EOSC), and Digital Twin projects, have selected the Kunming-Montreal Global Biodiversity Framework (K-M GBF) as a testbed for contributing to the SDGs. Their collective focus is on the network shared impact rather than individual projects. By examining a common approach to the K-M GBF, they aim to enhance their contributions to the framework's strategic goals, particularly its 2030 and 2050 targets. In this direction, the network: Recognises the contribution and rights of indigenous peoples and local communities as custodians of biodiversity and holders of traditional knowledge for the conservation, restoration, and sustainable use of ecosystems. By adhering to the Open Science principles of “Findable Accessible Interoperable Reusable” (FAIR) and “Collective Benefit, Authority to Control, Responsibility, Ethics” (CARE), and by being consistent with the practices adopted by the scientific community, the members of the network promote traceability of their work and of the materials they use, including those provided by indigenous peoples. Implements a variety of approaches to improve biodiversity monitoring, management, and protection. It promotes multi- and cross-disciplinary, integrative approaches to enhance its contribution to many of the Framework objectives. Its members support research on biodiversity at all levels of the biological organisation, from single-celled organisms, through collections and specimen data and up to the scale of ecosystems, as well as on how biodiversity responds to climate change. A key role in this process is already being played by the biodiversity Research Infrastructures, both in the EU and globally, through bi- and multi-directional linking and an increased interoperability of their data holdings, the provision of advanced access to semantically structured FAIR data, the provision of single points of access to federated data discovery from different data domains, thus supporting multi-disciplinary research addressing questions of high complexity and importance to society. All organisations in the network are committed to the three principal objectives of the Convention on the Biological Diversity, namely conservation, sustainable use, and fair sharing of benefits derived from the utilisation of natural resources. They contribute significantly to the three above principal objectives of the CBD, by: (a) making biodiversity information readily available and developing systems to support decision making and conservation efforts that directly contribute to our ability to live sustainably with nature, as concerns the first of the principal objectives above; (b) identifying priorities and targets and raising awareness of the need to streamline efforts among scientific and societal actors, are critical elements towards the second objective; (c) developing technologies to enable the sharing of data, services and other products related to genetic resources, which are used in combination with any other type of resource or product (e.g. taxonomic, literature, environmental, etc.), are included among the activities to achieve the third principal objective. Contributes to the achievement of the K-M GBF objectives through science, technology and innovation, based on scientific evidence, traditional knowledge, and innovative practices. This support is translated into activities such as: (a) providing solutions for research, data sharing and management, and scientific computing solutions to researchers, learners, policy makers, public administrations and businesses; (b) developing standard operating procedures, implementing standards, and promoting open science principles to enhance research integrity, accuracy and accountability in science; (c) providing federated research services, resources, and other research products to promote multidisciplinary knowledge and innovation; (d) creating models (e.g. of climate and human activity related land-use changes in biodiversity dynamics and ecosystem services), automated data flows (from sensors to data systems) and integration (e.g. biodiversity data flows combined with environmental and human activity variables; (e) building digital twins for informed decision making, such as the European Digital Twin of the Ocean (European DTO), with assured connectivity to newly collected high quality environmental and biodiversity data; (f) providing training and capacity building services for innovative tools. Supports the consideration of the ecosystem approach principle in the implementation of the K-M GBF, with a number of activities being developed by the network: (a) providing virtual representations of the ocean and land, integrating observations, modelling, and digital infrastructures, and creating digital twins that allow the scientific community to simulate and study “what if” scenarios; (b) developing and implementing technologies that enable a cross-domain, multidisciplinary approach to the study of biodiversity and ecosystems; (c) promoting ecosystem-based approaches to biodiversity management and habitat conservation in innovative publications venues (e.g. Nature Conservation, Biodiversity Data Journal, One Ecosystem, etc.). Promotes collaboration and synergies between the Convention on Biological Diversity and its Protocols, as well as with other biodiversity-related conventions, relevant multilateral agreements and international organisations and processes, as this will facilitate the implementation of the K-M GBF. The network is developing a variety of work, including: (a) collaborating with bodies and organisations responsible for the implementation of the CBD and its Protocols (e.g. IUCN, IPBES, European Commission) to co-design and co-develop research resources and products to support their mandates; (b) establishing strong links with policy actors such as the European Commission and the European Parliament, the JRC and others. Participate in social, scientific and technical initiatives in the European arena, such as the European Green Deal, the EU Knowledge Centre for Biodiversity and its Science Service for Biodiversity, the Biodiversity Knowledge Hub, the EU Pollinators Initiative and the EOSC. Developing links with the private sector through the Science/Business initiative, cooperation with the European Environmental Bureau (EEB), and the EOSC Digital Innovation Hub (EOSC DIH); (c) integrating and sharing of computational resources and expertise will not only advance the frontiers of scientific knowledge, but also ensure that data-driven research initiatives around the world are well supported. Contributes to the understanding and researching of the links between biodiversity and health. Particular emphasis will be placed on the following activities: (a) participating in initiatives and projects such as the EOSC Health Cluster, a platform for interdisciplinary research, EC projects such as B4Life, B-Cubed and BioAgora by publishing research that investigates how biodiversity affects human health; (b) using data from multiple sources to numerically demonstrate the links between human and environmental health, in the context of the One Health concept; (c) using digital twins to create Virtual Research Environments (VREs) that generate knowledge on how biodiversity patterns derived from taxa and habitats interact with patterns derived from data and information on their health; (d) publishing the results of the research, such as studies on zoonotic diseases, biodiversity and mental health, and the benefits of ecosystem services for public health. During the workshop, the participants will present their collective contribution to the implementation of the K-M GBF and invite international and regional stakeholders to present their expectations on the above topic. Based on stakeholder input, the network will publish a white paper outlining its approach. Finally, these communities will issue an open call to forge an international alliance to further integrate biodiversity conservation into the priorities of the UN Summit of the Future agenda priorities and the post-SDG agenda.

Lentic waters are biogeochemical reactors, producing and receiving carbon (C) originally fixed by the terrestrial and aquatic biosphere, which is then buried in sediments or respired back to the atmosphere in the forms of carbon dioxide (CO2) and one of the more potent greenhouse gas (GHG) methane (CH4). Additionally, lakes serve as archives of terrestrial and aquatic carbon processes within their sediments, enabling the reconstruction of historical changes spanning thousands of years. These changes encompass alterations in land cover, indicated by pollen records, soil carbon erosion and shifts in lake productivity resulting from changes in land use and climate. Both the burial of C in lakes and the emissions of GHGs are recognised as important components of Earth's climate system, yet they remain poorly understood and constrained due to inadequate quantities and qualities of observations. In the case of GHG emissions from lakes, observations are often sporadic, failing to capture the significant spatial and temporal variations in emissions across diverse lentic systems. To address this challenge, process-based models that incorporate the interconnected biogeochemical processes occurring within lakes and their watersheds would arguably be the best tool to extrapolate from site-level observations to regional and finally global scales, to quantify the anthropogenic impact on these fluxes and to reconstruct long-term shifts in emissions and burial due to changes in land cover and climate. However, the development and evaluation of such models is hampered by the lack of observations in sufficient quality. In this project, we bring together a unique consortium of specialists in aquatic ecology, biogeochemistry, palynology, sedimentology and modelling of terrestrial and aquatic biogeochemistry. This project will put forth a national programme of systematic, long-term observations of lake GHG and C cycling processes of unmet detail, consistency and quality. First, at 40 pilot sites spanning typological and environmental gradients, there will be a comprehensive data acquisition endeavour to evaluate biological processes and mesological factors influencing the sequestration or recycling of organic carbon. This effort will be complemented with a synthesis of existing data (WP1). Second, based on well-dated sediment records, which include both newly-acquired and synthesised existing data, variability of lake C burial and their climate and land-use controls will be reconstructed over the past 150 years (WP2). For 15 of these pilot sites, reconstruction will go back until the mid-Holocene (5,000 years BP), allowing us to shed light on the anthropogenic perturbation of the C cycle in this earlier part of human history, which is commonly excluded from this type of research due to lack of information. The activities of these first two WPs will result in an open-source national database, guaranteeing valorisation of our research far beyond this project. In WP3, we will use the land surface model (LSM) ORCHIDEE C-lateral to assess C cycling in the terrestrial biosphere and the mobilisation of biospheric C into lakes, which is possible due to an explicit representation of soil C leaching and erosion processes and a downscaling scheme permitting us to assess C exports from watersheds at sub-grid scale. While LSMs are used to assess evolution of biospheric C budgets from the beginning of the Industrial Period, we will use it to hindcast the evolution since the mid-Holocene, using lake sediment records for model validation. Moreover, we will develop a new process-based lake C model supported by the database established in WPs 1 and 2, which we will couple to ORCHIDEE C-lateral to simulate lake C burial and GHG emissions in response to climate and processes in the lake watershed. This model set-up will first be used to better constrain contemporary large-scale lake GHG emissions and to disentangle the anthropogenic perturbation of these fluxes from the natural background flux. These estimates will be revolutionary, as they will allow attributing part of lake GHG emissions to anthropogenic emissions for national GHG budget reporting. Then, these models will be emulated to reconstruct evolution of lake GHG budgets and C budgets of the whole lake watershed since the mid-Holocene. While simulations will first be performed at the scales of France and Europe, the development of international partnerships to implement observations from other biomes (WP4) will finally support simulations at the global scale.

Extreme climate events such as floods and droughts are becoming increasingly frequent and intense across the world. Future climate scenarios predict both an increase in individual extreme events, as well as chronic changes in climatic seasonality. Yet, the combined and relative effects of these pressures on ecosystems remain unknown. Concurrently, human-induced ecological disruption is accelerating species extinction rates, which are estimated to be 100 to 1000 times greater than pre-human levels. This is alarming as greater biological diversity is thought to buffer ecosystem functioning against extreme climate events, thereby safeguarding the provisioning of essential ecological services that contribute to human well-being. However, how and to what extent biodiversity buffers ecosystems against climate variability remains unclear. We recently constructed experimental grassland communities in a mesocosm-based field design representing a realistic gradient of plant diversity. Both extreme events (drought and flood) and a change in seasonality of precipitation are manipulated in a full factorial design to quantify the effects of future seasonal shifts and extremes in precipitation. We will: 1) determine to what extent higher biological diversity ensures that grasslands can continue to provide multiple ecosystem services even in the context of climate change and 2) unravel the fundamental mechanisms by which this is achieved including species asynchrony and positive species interactions. Results of our experimental approach will advance our understanding of the buffering potential of plant diversity and contribute to the development of strategies for sustainable service provisioning of our ecosystems in the face of climate change.
