Gaps and biases in the ecological evidence underlying global biodiversity impact assessments
Published: 2026-10-22
Subjects: Biodiversity, Life Sciences
1. Halting global biodiversity loss requires methods that link biodiversity impacts to both their direct drivers and the human activities that generate them. Biodiversity footprint assessment has emerged as a key framework for establishing these connections, resulting in the rapid development of diverse methods and applications. Central to these approaches are characterisation factors (CFs), [...]
Vert-NSM: neural shape models for shape completion, classification, and landmark-free morphometrics of vertebrate specimens
Published: 2026-10-22
Subjects: Biodiversity
Natural history museums are building digital 3D archives at a scale that enables geometric morphometric analysis across thousands of specimens. Landmark-based analyses depend on anatomical priors and often exclude unidentified and incomplete specimens, which are abundant in collections and the fossil record. Continuous shape representations offer a landmark-free alternative that can be combined [...]
Genetic diversity must underpin area-based conservation and restoration targets
Published: 2026-10-22
Subjects: Biodiversity, Environmental Policy, Genetics and Genomics, Life Sciences
The mid-term review of the Kunming-Montreal Global Biodiversity Framework reveals highly uneven progress in halting biodiversity loss, especially for genetic diversity (Target 4) which underpins ecosystem function and species’ adaptive potential in a changing environment (Des Roches et al., 2018). Over 70% of the Parties have set national targets to conserve and restore genetic diversity, yet, so [...]
Synergistic phenology and range shifts in boreal butterflies are controlled by species' overall response capacity
Published: 2026-10-21
Subjects: Biodiversity, Population Biology
Species track climate warming through shifts in both phenology and geographic distributions, but the strength of association between these responses remains poorly understood. Although recent research points to a tendency of species to shift across either the temporal or spatial gradient, there is no comprehensive understanding of how generalizable these phenology and range shifts are and whether [...]
The role of long-distance dispersal for community dynamics of fungi
Published: 2026-10-21
Subjects: Biodiversity, Population Biology
Realized dispersal ability of wind-dispersing fungi in natural conditions remains poorly understood. Here, we study how climate, habitat type and long-distance dispersal jointly structure fungal communities and how their effects vary between species that have different morphological and life history traits. We integrate global fungal (spores and other organismal material) occurrence data [...]
The Doñana Digital Twin: integrating heterogeneous data into iterative, mechanistically grounded forecasts of biodiversity change
Published: 2026-10-20
Subjects: Biodiversity, Biology, Integrative Biology, Population Biology, Terrestrial and Aquatic Ecology
Natural ecosystems are increasingly impacted by multiple global-change drivers, and these impacts propagate non-linearly from individuals to populations and to communities. To anticipate ecological change under such complexities and mitigate negative impacts, we require integrated, mechanistically-grounded approaches to prediction. For mitigation strategies to be adaptive, predictions must also [...]
Shelterbelts: A Python library for characterising farmland tree groups and their influence on nearby pasture and cropland
Published: 2026-10-15
Subjects: Agricultural Science, Biodiversity, Other Ecology and Evolutionary Biology, Other Forestry and Forest Sciences
Shelterbelts is an open source Python library for mapping and categorising groups of trees in agricultural landscapes, and the corresponding shelter provided to nearby pixels based on the wind direction or density of tree cover. Starting from a binary tree raster, pixels are labelled into ecologically meaningful categories based on their structure and location including: scattered trees, forest [...]
Understanding the Global Report on Collective Progress in the Implementation of the Kunming-Montreal Global Biodiversity Framework: Purpose, Content, and Science-Policy Engagement
Published: 2026-10-14
Subjects: Biodiversity, Life Sciences
The Kunming-Montreal Global Biodiversity Framework (KMGBF), adopted under the Convention on Biological Diversity (CBD), establishes four long-term 2050 goals, 23 action-oriented 2030 targets, and a standardized monitoring framework to track collective progress. The 2026 global review marks the first operational test of the Party-led planning, monitoring, reporting, and review (PMRR) mechanism, [...]
Estimated Time to Act: A Global Assessment of Biodiversity Exposure to Human Modification
Published: 2026-10-13
Subjects: Biodiversity, Other Ecology and Evolutionary Biology, Spatial Science
Biodiversity loss is accelerating under compounding human pressures, yet most conservation tools quantify the pressure species already face, rather than when it will push them beyond the levels they have experienced. This temporal blind spot limits proactive planning, particularly under the Kunming-Montreal Global Biodiversity Framework (GBF), which sets action-oriented targets for 2030 and [...]
Spatial variation in keystone predation on foundation species drives local and landscape- scale diversity patterns
Published: 2026-10-13
Subjects: Biodiversity, Marine Biology, Other Ecology and Evolutionary Biology
The proposition that keystone predators increase biodiversity has been criticized for failing to consider the species facilitated by, rather than outcompeted by, dominant prey. Here, we revisit the relationship between the original keystone species, Pisaster ochraceus, and the diversity of rocky intertidal communities inclusive of competitively dominant prey, competitively subordinate [...]
Large Language Models for Marine Protected Area Design and Management Planning
Published: 2026-10-12
Subjects: Artificial Intelligence and Robotics, Biodiversity, Bioinformatics, Natural Resources and Conservation
Achieving biodiversity targets requires advances in marine conservation planning and action. We make three arguments about large language models (LLMs): they add more value when embedded within decision-support systems; they integrate fragmented expertise, data, and tools; they can increase capacity in under-resourced settings through co-design. We illustrate these arguments with a conceptual [...]
Spatially explicit sampling of AM fungal biomass reveals links to community characteristics and landscape context
Published: 2026-10-09
Subjects: Agriculture, Biochemistry, Biodiversity, Ecology and Evolutionary Biology, Environmental Microbiology and Microbial Ecology Life Sciences, Life Sciences, Other Ecology and Evolutionary Biology
Arbuscular mycorrhizal (AM) fungi are important contributors to soil functioning, yet their biomass and diversity may respond differently to environmental characteristics and historical legacies. Understanding these relationships is necessary for evaluating AM fungi as indicators of soil health. We investigated relationships among AM fungal biomass, community properties and natural habitat [...]
Amphibians and reptiles in bird nests and bird-excavated cavities: a mini review
Published: 2026-10-07
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Bird nests and bird-excavated cavities provide suitable environments for egg incubation and nestling development. However, bird-created structures are also exploited by a wide range of organisms, including taxa that are phylogenetically distant from the avian constructors. While birds, mammals, and invertebrates are well documented as secondary users of nests and cavities, the occurrence of [...]
Areas of high conservation priority for threatened terrestrial vertebrates are governed by novel ecological conditions
Published: 2026-10-07
Subjects: Biodiversity, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
Over half of the terrestrial biosphere is exposed to highly novel conditions that differ from the historical state, resulting from anthropogenic pressures such as climate change, floristic disruption, and defaunation. Highly novel conditions result in unpredictable biodiversity outcomes, impacting the effectiveness of conservation and restoration actions and the ability for threatened species to [...]
