Bats in Habitats, Bats as Habitats: An integrative ecological framework for understanding synergistic interactions across levels of community organization
Published: 2025-02-03
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Integrative Biology, Systems Biology
Global biodiversity and ecosystem function are the result of complex networks of interactions and feedbacks between animals and their environments, which in turn are affected by the interactions and feedbacks between animals and the organisms they host. Understanding these complex networks, including the main drivers of and responses to ecological and environmental changes and their global [...]
Borealization of plant communities in the Arctic is driven by boreal-tundra species
Published: 2025-02-03
Subjects: Ecology and Evolutionary Biology
Following rapid climate change, tundra plant communities are experiencing extensive compositional shifts. A conservation concern is the potential encroachment of boreal species into the tundra (‘borealization’). Tundra borealization has been sporadically reported, but not systematically quantified. Here, we synthesized data from across 32 study areas, spanning 1,137 plots and 287 vascular plant [...]
Promoting the use of phylogenetic multinomial generalised mixed-effects model to understand the evolution of discrete traits
Published: 2025-01-30
Subjects: Ecology and Evolutionary Biology, Evolution
Phylogenetic comparative methods (PCMs) are fundamental tools for understanding trait evolution across species. While linear models are widely used for continuous traits in ecology and evolution, their application to discrete traits - particularly ordinal and nominal traits - remains limited. Researchers sometimes recategorise such traits into binary traits (0 or 1 data) to make them more [...]
Cognitive evolution in major vertebrate clades: the Lack of Attentional Control hypothesis and the Cognition-Opportunities-Needs framework
Published: 2025-01-29
Subjects: Animal Sciences, Animal Studies, Biology, Ecology and Evolutionary Biology, Neuroscience and Neurobiology
The observed difference in relative brain size between endotherms and ectotherms raises questions about potential resulting disparities in brain function between these two groups. Until recently, no clear cognitive advantage was found in endotherms, with ectotherms occasionally even outperforming them in seemingly complex tasks. However, recent research on working memory—a core executive [...]
Powerful yet challenging: Mechanistic Niche Models for predicting invasive species potential distribution under climate change
Published: 2025-01-29
Subjects: Biodiversity, Bioinformatics, Ecology and Evolutionary Biology
Risk assessments of invasive species are among the most challenging applications of species distribution models (SDMs). This challenge arises from the disequilibrium in invasive distributions, where recorded occurrences do not fully represent the species' potential range. The spatiotemporal dynamics of invasive populations are shaped by intraspecific variability, human-mediated introductions, [...]
Challenges and solutions for ecologists adopting AI
Published: 2025-01-29
Subjects: Computer Sciences, Ecology and Evolutionary Biology
Artificial Intelligence (AI) can rapidly process large ecological datasets, uncover patterns, and inform conservation decisions. However, its adoption by ecologists is often hindered by steep learning curves, overwhelming model options with varying transparency, and uneven access to data, code, and technical skills. We led a workshop, EcoViz+AI: Visualization and AI for Ecology, that brought [...]
Incorporating responses of functional traits to changing climates into species distribution models: A path forward
Published: 2025-01-29
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Conventional species distribution models (SDMs) typically consider only abiotic factors, thus overlooking critical biotic dimensions, including functional traits that play an important role determining species’ distributions in changing environments. Process-based models explicitly incorporate functional traits and have been applied to SDMs. However, their parameterization can be complex and [...]
Bridging data silos to holistically model plant macrophenology
Published: 2025-01-29
Subjects: Ecology and Evolutionary Biology, Life Sciences, Plant Sciences
Phenological response to global climate change can impact ecosystem functions. There are various data sources from which spatiotemporal and taxonomic phenological data may be obtained: mobilized herbaria, community science initiatives, observatory networks, and remote sensing. However, analyses conducted to date have generally relied on single sources of these data. Siloed treatment of data in [...]
Extreme events drive rapid and dynamic range fluctuations
Published: 2025-01-26
Subjects: Ecology and Evolutionary Biology
Climate change is altering species’ distributions globally. Increasing frequency of extreme weather and climate events (EWCEs) is one of the hallmarks of climate change. Despite species redistribution being widely studied in response to longer-term climate trends, the contribution of EWCEs to range shifts is not well understood. We outline how EWCEs can trigger rapid and unexpected range boundary [...]
Weather and catchment morphology drive thermal regime variation among sub-Arctic ponds, and possible effects on resident Arctic charr
Published: 2025-01-21
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Thermal stratification, which is a common feature of lentic freshwater systems, has extensive effects on ecological interactions and ecosystem function, including processes that may determine which ponds can support fish populations and affect growth, phenology, and metabolism where populations exist. Because these habitats are important for Northern freshwater fishes, improvement of our ability [...]
Bottom-up interactions in age-structured stock assessment and state-space mass-balance modelling
Published: 2025-01-20
Subjects: Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Population Biology
Age-structured stock assessment models are used worldwide to predict the likely impact of changing harvest on future fisheries yield. However, age-structured models ignore the impacts of predator consumption on prey survival (top-down impacts) and prey availability on predator growth (bottom-up impacts), whereas multispecies statistical catch-at-age models often incorporate top-down but not [...]
From Policy to Practice: Progress towards Data- and Code-Sharing in Ecology and Evolution
Published: 2025-01-20
Subjects: Ecology and Evolutionary Biology, Life Sciences
High quality research data and analytical code are essential for ensuring the credibility of scientific results, are key research outputs, and are crucial elements to facilitate reproducibility. However, in ecology and evolution (E&E) in particular, it is currently unknown how many journals have policies on data- and code-sharing for peer review purposes, or upon manuscript acceptance. [...]
Using seed germination as a proxy of restoration success
Published: 2025-01-16
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Ecological restoration of post-mining landscapes is critical to mitigating the environmental impacts of extraction activities. This study compares the effectiveness of geomorphic restoration (GR) versus conventional restoration (CR) techniques in improving soil water availability and seed germination dynamics in the Fortuna quarry, a Mediterranean post-mining site in Spain. Soil water content [...]
Reproductive consequences of mate retention and divorce in a short-lived migratory passerine
Published: 2025-01-16
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
In socially monogamous birds, pair bond duration varies widely across species, from single-breeding associations to long-lasting, multi-year bonds. Studies on mate retention and divorce have predominantly focused on long-lived species, while research in short-lived and migratory species is limited. Consequently, the fitness consequences of divorce or remating in these species remain unclear. [...]
Population structure plays a key role in community stability
Published: 2025-01-09
Subjects: Applied Mathematics, Ecology and Evolutionary Biology, Life Sciences, Physical Sciences and Mathematics
The relationship between ecosystem complexity and stability remains unresolved and a mechanistic explanation for the stunning levels of biodiversity observed in communities and ecosystems is still lacking. Recent work has shown that differences in the foraging capacity and predation risk of juveniles versus adults within populations result in larger, more complex communities than predicted by [...]
