ENCORE (Exploring Natural Capital Opportunities, Risks and Exposure) has established itself as a key reference for business and financial institution assessment of exposure to risk stemming from nature degradation. It has over 18,000 users, has been used in over 15 [...]
Assessing habitat associations of critically endangered big-headed turtles to support grassroots river conservation
Published: 2026-09-05
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Modern wildlife conservation relies primarily on state-run protected areas and hunting regulations, whereas grassroots initiatives to protect ecosystems from various threats such as large-scale infrastructure development are underrecognized and receive limited scientific support. We studied critically endangered big-headed turtles (Platysternon megacephalum) to support a grassroots river [...]
From population trends to biodiversity changes: synthesizing multi-species signals of collapse
Published: 2026-09-05
Subjects: Biodiversity, Ecology and Evolutionary Biology
Taking the pulse of biodiversity is no small feat, and abundance time series are some of the most valuable data we have to measure change. Biodiversity changes are often complex, with some species declining while others grow, leading to a reorganisation of the network of interactions between species. The infamous decline of Atlantic cod in the Newfoundland shelf groundfish community between 1981 [...]
Socioeconomic policy and large mature trees are vital for moor macaque (Macaca maura) conservation in anthropogenically-modified landscapes
Published: 2026-09-01
Subjects: Biodiversity, Energy Policy, Environmental Law, Environmental Policy, Policy Design, Analysis, and Evaluation, Population Biology, Zoology
Despite conservation efforts, intensifying anthropogenic pressure is transforming tropical forests into anthropogenically-dominated landscapes. We investigated how current anthropogenic pressure and socioeconomic-climate policies influence tropical forest ecology, using the Endangered moor macaque (Macaca maura) in southwestern Sulawesi, Indonesia, as an example species. Deploying camera traps [...]
What goes up, must come down: air–soil microbiome connectivity and its implications for ecosystem functioning
Published: 2026-08-28
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences, Microbiology
Soils harbor Earth's largest reservoir of microbial diversity, yet enormous numbers of microorganisms are continuously aerosolized, transported through the atmosphere, and redeposited across landscapes. Although soil and the atmosphere have largely been studied separately, here, we propose a conceptual framework that views soils and the atmosphere as a coupled microbiome linked by bidirectional [...]
FROM CLIMATE AWARENESS TO CLIMATE-INFORMED PLANNING IN EXISTING MARINE PROTECTED AREAS
Published: 2026-08-26
Subjects: Biodiversity, Environmental Health and Protection, Environmental Indicators and Impact Assessment, Environmental Monitoring, Environmental Studies, Other Environmental Sciences, Physical and Environmental Geography, Social and Cultural Anthropology, Sustainability
Marine protected areas underpin global biodiversity commitments, but climate change challenges management systems built around historical conditions. Existing guidance defines climate adaptive practice, yet many plans contain resilience-supporting provisions without linking them explicitly to climate decisions. We present CliMPA, a human-centred framework that connects management needs, actor [...]
iPhone Lidar Can Accurately Capture Fine-Scale Understorey Vegetation Structure
Published: 2026-08-21
Subjects: Biodiversity, Ecology and Evolutionary Biology, Other Plant Sciences, Terrestrial and Aquatic Ecology
Complex vegetation structure increases ecosystem resilience, but fine-scale understorey vegetation is often overlooked in monitoring protocols despite subtle variation impacting overall diversity. iPhone lidar has placed cost effective and portable remote sensing technology in the pockets of researchers, farmers, practitioners, and citizens worldwide to conduct continuous monitoring and improve [...]
Linking movement to mortality: a framework for predicting anthropogenic mortality hotspots in wide-ranging animals
Published: 2026-08-21
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Human activities and their impacts are a major source of mortality for wide-ranging animals, yet conservation efforts often remain reactive because it is difficult to predict where mortality is most likely to occur. Approaches to understand and reduce wildlife mortality typically rely on coarse-scale associations between mortality events and landscape features, limiting their ability to identify [...]
Robust and realistic power analysis for cost-effective monitoring of occupancy trends
Published: 2026-08-21
Subjects: Biodiversity, Life Sciences
Structured monitoring programs play a key role in identifying whether a population is declining, stable, or increasing, and power analyses allow program planners to determine the number of sampling units required to reliably estimate a specified trend (e.g., 1% annual decline) with a specified error rate (e.g., α=0.20, or 80% power). Increasingly, monitoring programs track trends in site [...]
IUCN Red List Threatened Bird Classification from Citizen-Science Images using Fine-Tuned CNN Features and a Hierarchical Lightweight Classifier
Published: 2026-08-18
Subjects: Artificial Intelligence and Robotics, Biodiversity, Ecology and Evolutionary Biology, Ornithology
To prevent bird strikes at wind farms, an approaching protected bird must be identified so that the turbine can be halted before a collision. We present a bird-species classification module intended for that real-time, low-power edge setting: a hierarchical system assigning IUCN Red List categories to in-the-wild citizen-science bird images, combining a ResNet50 feature extractor fine-tuned on a [...]
The knowledge landscape of jaguar science: rapid growth, thematic structure, and regional inequalities
Published: 2026-08-17
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences
Understanding how scientific effort is distributed is essential for evaluating the evidence available to guide species conservation. We assessed the temporal, thematic, methodological, and spatial organization of jaguar (Panthera onca) research across the species’ range. Using 1,028 bibliographic records, we applied a metadata-based scope filter, defining a primary analytical corpus of 857 [...]
Beyond participation: Indigenous researchers leading biodiversity monitoring and territorial governance in the Amazon
Published: 2026-08-14
Subjects: Biodiversity, Integrative Biology
Indigenous Territories harbor some of the world’s best-preserved ecosystems and are central to biodiversity conservation. Paradoxically, the knowledge of the people who have historically maintained these ecosystems remains underrepresented in conservation science. Here we present a collaborative program for monitoring biodiversity and water quality of the Nãnsêpôtiti (Iriri) River in the Panará [...]
Using large language models to identify reporting challenges for Target 6 implementation: a short validation against human assessment
Published: 2026-08-14
Subjects: Artificial Intelligence and Robotics, Biodiversity, Research Methods in Life Sciences
National reports and related biodiversity policy documents contain important information on implementation barriers, but extracting comparable evidence across many countries is timeconsuming. We tested whether large language models (LLMs) could provide a reliable firstpass synthesis of reported challenges relevant to Target 6 of the Kunming–Montreal Global Biodiversity Framework. Human assessor [...]
Reproduction is more sensitive to warming than adult lifespan across invertebrates
Published: 2026-08-11
Subjects: Animal Sciences, Biodiversity, Entomology, Life Sciences, Population Biology, Terrestrial and Aquatic Ecology
Studies estimating the effect of temperature on wild animal populations typically focus on survival as a proxy for population health. However, high and low temperatures can also negatively influence animal reproduction, and recent work suggests that the thermal sensitivity of reproduction is more important for population persistence that the thermal sensitivity of survival in some species groups. [...]
How (not) to study insect microbiota in the age of high-throughput sequencing
