Global biodiversity measurement to meet scale-dependent needs and opportunities
Published: 2025-10-02
Subjects: Biodiversity, Business, Ecology and Evolutionary Biology, Environmental Studies, Life Sciences, Social and Behavioral Sciences
In the face of rapid ecological decline, biodiversity information is essential for safeguarding life on Earth. Although this information is increasingly valued by governments, businesses, and other stakeholders, it remains insufficiently accessible and usable. Because the rarity and functions of biodiversity vary greatly across land- and seascapes, the global and local ecological and social [...]
Native bee genus diversity within bee-friendly urban gardens varies little along an urbanization gradient
Published: 2025-09-30
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology
Urban bee populations are threatened by ongoing habitat loss and fragmentation. Bee-friendly gardens with abundant forage and nesting resources may help offset these pressures, but attributes of the broader urban landscape could also play an important role. We explored bee diversity within 32 bee-friendly gardens distributed throughout the city of Kelowna, British Columbia. Our objectives were to [...]
CartograPlant: Bridging genomic, phenotypic, and environmental data to advance plant resilience and eco-evolutionary insight
Published: 2025-09-30
Subjects: Agriculture, Biodiversity, Bioinformatics, Ecology and Evolutionary Biology, Genetics and Genomics, Integrative Biology, Life Sciences, Plant Biology, Plant Breeding and Genetics Life Sciences, Plant Pathology, Systems Biology
Climate change is threatening plant health and productivity at all spatial scales, and these impacts are further compounded by the rising incidence of invasive pests and pathogens. Effectively addressing these challenges requires a comprehensive understanding of plant demography as well as the mechanisms and drivers of adaptation. Achieving this understanding requires the integration of [...]
Born this way: individuality is seeded before birth and robust to environmental stress
Published: 2025-09-29
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology
Behavioral individuality, or consistent individual differences in behavior, are pervasive across the animal world and have major ecological and evolutionary consequences. Nevertheless, we still have a limited understanding of what drives individuality and how it emerges during ontogeny. Here, we subjected clonal individuals to a ubiquitous yet critical environmental challenge—the threat of [...]
Species Invasion in a Two-Dimensional Space with Irregularly Shaped Patches
Published: 2025-09-24
Subjects: Ecology and Evolutionary Biology, Population Biology
Accounting for spatial heterogeneity in the evolution of a species population in a given space is of much importance in population ecology, epidemiology and related fields in biosciences. Past literature has presented such analysis in the presence of regions with distinct diffusion/growth properties, often referred to as patches. However, most of the past work is limited to one-dimensional space, [...]
Spatial networks of habitats, populations, and communities: connecting approaches to keep cutting edges
Published: 2025-09-23
Subjects: Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology, Population Biology, Terrestrial and Aquatic Ecology
Purpose of review: Spatial networks are extensively used in ecology to represent exchanges among landscape features (e.g., habitat patches, river segments) or biological entities (e.g., individuals, populations, communities). I reviewed the literature produced in the past 25 years using these networks. Distinct types of spatial networks have emerged in several subfields of ecology. I aimed to [...]
A high-resolution physiological timeseries uncovers strong but variable seasonal acclimation of thermal limits in a copepod community
Published: 2025-09-23
Subjects: Comparative and Evolutionary Physiology, Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
How a community responds to warming depends on both intra-specific variation in thermal limits and variation in acclimation capacity across community members. These factors, however, are often overlooked, leading to uncertainties about how climate change affects biodiversity. In temperate regions, communities are exposed to large seasonal temperature fluctuations, providing an opportunity to [...]
Movement-informed projections of Bristol Bay red king crab seasonal distribution to support spatial management decisions
Published: 2025-09-22
Subjects: Aquaculture and Fisheries Life Sciences, Ecology and Evolutionary Biology, Marine Biology
Understanding seasonal shifts in the spatial distribution of Bristol Bay red king crab (BBRKC) is essential to developing adaptive management strategies that promote sustainable harvest. Although fishery harvests suggest a substantial shift in the distribution of male crab between late spring (when fishery-independent bottom trawl surveys occur) and autumn (during the directed fishery), the [...]
A Unified and Predictive Measure of Functional Diversity
Published: 2025-09-19
Subjects: Biodiversity, Ecology and Evolutionary Biology
Despite the critical role of functional diversity (FD) in understanding ecological systems and processes, its robust quantification remains a significant challenge. A long-held view in the field is that it is not possible to capture its three facets---functional richness, functional divergence, and functional evenness---in a single index. This perspective has prompted recent proposals for FD [...]
What defines an urban butterfly? Life history traits and habitat associations of butterflies in urban environments
Published: 2025-09-19
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Forest Sciences, Life Sciences
Urban areas are encroaching onto semi-natural areas the world over, driving species assemblages into homogenisation. A better understanding of the life history and habitat association traits can help support management efforts to improve urban biodiversity. Urban areas present an ecological filter, limiting the number of species present compared to the wider countryside. What characteristics help [...]
Trophic Reorganization and Energy Deficit: A Multispecies Size-Spectrum Model of the Grand Banks
Published: 2025-09-16
Subjects: Ecology and Evolutionary Biology, Marine Biology
Marine ecosystems face unprecedented pressures from fishing and climate change, with both bottom-up energy transfer and top-down predation influencing ecosystem control, though their relative importance varies across space and time. The Grand Banks of Newfoundland provides a compelling case study, where capelin (Mallotus villosus) biomass collapsed by 99% in 1990–1991, followed by the collapse of [...]
Trends of ungulate species in Europe: not all stories are equal
Published: 2025-09-16
Subjects: Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology, Population Biology, Zoology
Wild ungulates have deep impacts on socio-ecological systems, and analyzing large-scale population trends in a multispecies set can identify their environmental and socio-economic drivers. We collected annual hunting bags (n = 11,046, period 1975-2018) of 7 wild ungulates of high management interest across 25 European countries. We identified different temporal trends in hunting bags and for roe [...]
Passive acoustic monitoring and deep learning reveal spatiotemporal patterns in gibbon calling behaviour associated with habitat and climate variables

The Southern Lesser Bushbaby Galago moholi is a small, nocturnal, strepsirrhine primate, native to Sub-Saharan Africa. Previously considered a strict dietary specialist on tree exudates and insects, recent observations have revealed hitherto unappreciated plasticity in its feeding behaviour, encompassing fruits and even small vertebrates. While arthropods are an important seasonal component of [...]
Mitochondrial genome evolution: the influence of partitioning, calibration, and gene heterogeneity on pleurodontan substitution rates
Published: 2025-09-14
Subjects: Ecology and Evolutionary Biology, Genetics and Genomics, Molecular Genetics
Substitution rate estimates are a key source of information in modern evolutionary biology, underpinning divergence time inference and other evolutionary analyses. Mitochondrial DNA nucleotide substitution rates, in particular, are commonly used for these purposes. However, these rates are typically derived from a small set of genes, closely related species, or from a limited number of model [...]
