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
Published: 2025-09-16
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology, Zoology
1. Understanding the basic ecology of endangered species is essential for effective conservation, yet this remains challenging for elusive species inhabiting tropical forests. For the endangered Bornean white-bearded gibbon (Hylobates albibarbis), basic ecological information remains limited. Most research on the species is restricted to peat swamp forests, while little is known from other forest [...]
Dietary preferences and behaviour of the Southern Lesser Bushbaby Galago moholi (Loriformes: Galagidae) foraging at an entomological light trap
Published: 2025-09-14
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Entomology, Life Sciences
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 [...]
Ecosystem dynamics in dry heathlands: spatial and temporal effects of environmental drivers on the vegetation

Natural developmental temperatures of ectotherms: A systematic map and comparative analysis
Published: 2025-09-10
Subjects: Ecology and Evolutionary Biology, Life Sciences
In ectothermic animals, physiological processes are highly sensitive to environmental temperatures. Developmental temperatures, in particular, have large and long-lasting impacts on ectotherm phenotypes. However, most phenotypic responses are studied in the laboratory, and may not accurately reflect ecological impacts in natural environments. In this study, we provide the first synthesis of [...]
