The spatial dynamics of nutrient limitation in communities of generalist predators of crop pests
Published: 2026-10-30
Subjects: Agriculture, Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences, Nutrition, Zoology
Generalist arthropod predators vitally control crop pests, but their ability to perform this role relies on them obtaining sufficient nutrients within simplified crop environments. Field margins are thought to provide habitat and resources for predators, such as ground beetles, but how far into fields this provision extends is poorly understood. Since arthropod nutrient contents can vary [...]
A targeted metacollection of Nordic gardens reveals horticultural endemism of threatened woody plants
Published: 2026-10-30
Subjects: Biodiversity, Botany
There is huge potential for bringing together international networks of Botanic Gardens and Arboreta and pooling their resources for coordinated action to conserve threatened species. Realising this potential requires effectively managing complex, largely independently acquired data for tens of thousands of species and many more individual plants with different wild or cultivated origins. Here we [...]
Genomic costs without functional consequences in short-range endemics trapped in evolutionary refugia
Published: 2026-10-30
Subjects: Biodiversity, Bioinformatics, Evolution, Genomics, Life Sciences, Molecular Genetics
Species with small geographic ranges are often concentrated in evolutionary refugia, landscapes that support viable populations through significant climate oscillations. Under long-term stable environments and with small population size, species are predicted to evolve narrow climatic tolerances, lose genetic diversity and accumulate harmful mutations. Together, these predictions suggest that [...]
Mapping actor diversity is essential for advancing global seagrass conservation
Published: 2026-10-30
Subjects: Biodiversity, Human Geography, Marine Biology, Natural Resources and Conservation, Natural Resources Management and Policy
Seagrass conservation is increasingly organised around global agendas for protection, restoration, climate mitigation, biodiversity recovery and nature-positive finance. The actor systems that determine whether these agendas succeed remain poorly described, if at all. We developed a heuristic actor-centred framework for seagrass social-ecological systems, combining a literature scan with [...]
Discrepancies between climate velocity and dispersal capacity threaten subalpine forests in Northern Italy
Published: 2026-10-29
Subjects: Biodiversity, Forest Biology, Forest Management, Forest Sciences, Plant Sciences
The acceleration of anthropogenic warming is fundamentally altering the climatic space available to foundational conifer species in European alpine environments. This study evaluates the potential impacts of future climate scenarios on the spatial distribution and elevational displacement of four key taxa (Abies alba, Larix decidua, Picea abies, and Pinus sylvestris) in the Italian Alps. We [...]
How Much of the Forest Do Citizen Scientists Actually Record? A Decade of iNaturalist Sampling in the Hyrcanian Forests
Published: 2026-10-29
Subjects: Biodiversity, Forest Sciences
Citizen-science records increasingly inform biodiversity research and conservation planning, yet how much of a large forest they actually cover is rarely measured. We analyzed 1,700 research-grade iNaturalist records from the Hyrcanian Forest, northern Iran (2015–2025), on a 10 × 10 km grid, comparing observed coverage with null models. Annual records rose from 48 to 386, but occupied only 43.7% [...]
Noise as a global change driver: a meta-analysis of its fitness consequences for birds
Published: 2026-10-29
Subjects: Behavior and Ethology, Biodiversity, Biology, Ecology and Evolutionary Biology, Evolution, Life Sciences, Pharmacology, Toxicology and Environmental Health
Anthropogenic noise is a widespread yet underappreciated global pollutant. Despite mounting evidence that noise may affect the physiology and behaviour of birds, its consequences for fitness, and thus its capacity to impact population and evolutionary processes, remain unclear. Here, we conduct a pre-registered systematic review and meta-analysis of the causal effects of anthropogenic noise on [...]
Spatial crime scripting and meso-level analyses of illegal pangolin trade
Published: 2026-10-28
Subjects: Biodiversity, Life Sciences
Human-related threats such as poaching and illegal trade remain the dominant risk to pangolin conservation. Using crime science focused on illegal pangolin hunting, we compare expert vs. community member’s spatio-temporal knowledge about the different stages of pangolin poaching and trade process at a national scale; explore spatial trajectories between stages; and explore spatial predictors of [...]
Oak gall wasps lack conserved microbial symbionts
Published: 2026-10-23
Subjects: Biodiversity, Bioinformatics, Ecology and Evolutionary Biology, Entomology, Life Sciences
Herbivorous insects frequently rely on microbial partners to exploit their host plants, yet for gall-inducing insect taxa, there were few attempts to comprehensively resolve their microbial associations. To address this gap, we characterised microbial abundance, composition and specificity in three Polish populations of cherry oak gall wasps (Cynips quercusfolii), a highly specialized [...]
From Temperate to Boreal -- Untangling the Importance of Environment, Space, and Species Co-distributions in Forest Plant Distributions
Published: 2026-10-23
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology
Aim Quantify how environmental conditions, spatial autocorrelation, and species co-distributions shape forest plant community at regional scale. Location Southern Québec, Canada, between the 45th and 53rd parallels. Period From 1986 to 2000. Major taxa studied Vascular plants, mosses, and lichens. Methods We analyzed the presence-absence of 224 plant species across 28,210 ecological observation [...]
Beyond static species distribution models: temporally dynamic, spatially nested models reduce extrapolation for future projections
Published: 2026-10-23
Subjects: Biodiversity, Entomology
Species distribution models are widely used to project biodiversity responses to climate change, but geographically restricted training data can truncate species’ climatic niches, increasing reliance on extrapolation. Spatially nested models can reduce this truncation by incorporating climatic information from species’ wider distributions. However, how accounting for interannual environmental [...]
As open as possible, as protected as necessary: Proportionate governance for environmental DNA under the BBNJ Agreement
Published: 2026-10-23
Subjects: Biodiversity, Biology, Environmental Law, Marine Biology, Molecular Genetics
The Agreement on the Conservation and Sustainable Use of Marine Biological Diversity of Areas Beyond National Jurisdiction (BBNJ Agreement) establishes new arrangements for activities involving marine genetic resources and the sharing of resulting benefits. Direct pathways to resource utilisation are most apparent in conventional genetic workflows where whole organisms or tissues are collected [...]
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 [...]
