Taxonomic revisions, strategic decisions research and management priorities for the threatened greater glider complex
Published: 2025-11-11
Subjects: Animal Sciences, Biology, Ecology and Evolutionary Biology, Life Sciences, Zoology
Collating and synthesising ecological information is critical for guiding effective conservation policy and management plans. This is especially pertinent for species of conservation concern. This task may be further complicated when taxonomic revisions of species and species complexes occur. Species previously managed as a single taxon may be reclassified into multiple species, and hence [...]
Another brick in the wall of European subterranean spider knowledge: adding Macaronesian species and their traits to the picture
Published: 2025-11-11
Subjects: Ecology and Evolutionary Biology, Life Sciences
Caves and other subterranean ecosystems impose highly selective environmental filters, driving the evolution of convergent and specialized traits in subterranean organisms. Here, we present the first comprehensive checklist and trait database for subterranean spiders of Macaronesia, thereby filling a significant knowledge gap relative to continental Europe. We compiled data through direct [...]
The ecology of resting behaviour in terrestrial vertebrates, and potential effects of anthropization
Published: 2025-11-10
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Inactive behaviours are a major component of animals’ lives, generally representing important proportions of time budgets. The conditions in which they occur are thus likely to have key effects on individual fitness. Yet, relatively little research has focused on the determinants and ecological consequences of inactive behaviours, likely in part because of the inherent difficulties associated [...]
Climate change increases the distribution of reservoirs of the Raccoon Rabies Virus in Quebec
Published: 2025-11-07
Subjects: Ecology and Evolutionary Biology
Zoonoses often emerge in environments where human-animal interactions intensify. In Québec, climate change and land use alterations are suspected drivers in the shifts of the potential distribution of urban-adapted hosts such as raccoons (Procyon lotor) and striped skunks (Mephitis mephitis), which serve as reservoirs for Raccoon Rabies Virus (RRV; a variant of Lyssavirus rabies). We used species [...]
How much monitoring is needed to reliably track progress towards genetic diversity targets?
Published: 2025-11-07
Subjects: Biodiversity, Ecology and Evolutionary Biology, Genetics, Population Biology
Achieving global biodiversity targets hinges on indicators of biodiversity change that convert raw data into reliable numbers that can shape policy, conservation, management, and, ultimately, the future of biodiversity worldwide. Indicators can only be used confidently if they detect and summarise biodiversity trends as intended, given the available data worldwide. Knowing whether indicators can [...]
Emerging Applications of Large Language Models in Ecology and Conservation Science
Published: 2025-11-06
Subjects: Biodiversity, Ecology and Evolutionary Biology
The emergence of large language models (LLMs) marks a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep-learning architectures, these models can support a wide range of tasks, from analysing unstructured texts to enhancing biodiversity monitoring and generating policy-relevant insights. This [...]
The statistical fragility of animal cognition findings: a meta-meta-analytic reappraisal
Published: 2025-11-06
Subjects: Comparative and Evolutionary Physiology, Comparative Psychology, Ecology and Evolutionary Biology, Psychology
How reliable is the evidence in animal cognition research? Concerns are mounting over the statistical robustness of this and other fields. Many primary studies rely on small samples and rarely report null results, while meta-analyses sometimes overlook publication bias, all of which may contribute to unreliable conclusions. We conducted a second-order meta-analysis across 28 published [...]
Multilevel Selection Shaping Adaptive Social Networks
Published: 2025-11-05
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Human Ecology, Zoology
Understanding how human and non-human animal social networks evolve through emergent properties and feedback mechanisms is essential for explaining their adaptability and persistence. Collective social niche construction refers to the process where individuals, through their interactions, actively shape the social environment, resulting in network structures that influence individual behaviours [...]
Penguin diet from space: Links between sea ice, Antarctic food webs, and population change
Published: 2025-11-04
Subjects: Ecology and Evolutionary Biology
Rapid environmental change poses a threat to Antarctic ecosystems. However, the spatial scale of Antarctica and its extreme environment have precluded a synoptic understanding of the links between environmental change and ecological responses. Combining tools from imaging spectroscopy, stable isotope analysis, and hierarchical statistical modeling, we developed a novel method to quantify Adélie [...]
The Thermodynamic Imperative: Evolution as Entropic Resistance through Mergers and Persistence
Published: 2025-11-04
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
This paper presents a unified theory of persistence, presenting the argument that evolution should be reframed as an explanation of entropic resistance rather than reproductive fitness. Through theoretical exposition and case studies across the biological spectrum, I demonstrate that persistence emerges from the capacity to merge through complementarity, integrate functionally, and form [...]
Beneath the Pavement: Understanding mycorrhizal fungi in urban ecosystems and the path forward
Published: 2025-11-03
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Environmental Microbiology and Microbial Ecology Life Sciences, Environmental Studies, Human Ecology, Life Sciences, Microbiology, Social and Behavioral Sciences, Urban Studies and Planning
Urban expansion is reshaping ecosystems worldwide, yet the responses of mycorrhizal fungi—key mediators of plant–soil interactions—remain poorly understood. In this review, we synthesize current knowledge on the environmental and ecological factors shaping mycorrhizal fungal diversity, distribution, and function in cities. We highlight how greenspace and landscape features—including plant [...]
Environmental drivers of structural colour in bees (Hymenoptera: Anthophila)
Published: 2025-11-03
Subjects: Ecology and Evolutionary Biology
Aim: Environmental drivers frequently predict global patterns of colour diversity, but whether such patterns depend on the underlying colour mechanisms – pigments or microscopic structures – has scarcely been considered. Structural colour may have different functional properties that result in different associations with environmental variables. Here we test whether the presence of structural [...]
European beech reproduction is resilient to drought, including the 2003, 2018, and 2022 extremes
Published: 2025-10-30
Subjects: Ecology and Evolutionary Biology, Life Sciences
Climate change is intensifying drought stress in temperate forests, but its effects on tree reproduction, central to forest regeneration and migration capability, remain poorly understood. In mast-seeding species such as European beech (\textit{Fagus sylvatica}), reproduction is regulated by temperature cues rather than current-year resource availability, raising questions about drought [...]
Why do birds use green nest material? A systematic review and meta-analysis of experiments
Published: 2025-10-30
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Other Ecology and Evolutionary Biology
Many animals construct nests. Nests are often considered extended phenotypes that shape survival and reproduction beyond the builder’s body. Birds are key examples of nest builders, and many add fresh green plant material to their nests. Yet, the adaptive value of this behaviour remains debated. Non-mutually exclusive hypotheses propose roles in courtship signalling, parasite defence, or direct [...]
Microplastic interference influences Pseudomonas fluorescens in denitrification efficiency of wastewater treatment
Published: 2025-10-28
Subjects: Ecology and Evolutionary Biology, Microbiology, Pharmacology, Toxicology and Environmental Health
Wastewater treatment plants (WWTP) play an essential role in pathogen and contaminant removal in wastewater. While developed countries treat approximately 70% of industrial wastewater prior to discharge, only about 8% is treated in developing countries. WWTP solutions can reduce the solids load, including microplastics, by up to 98.4%. Still, it is estimated that about 65 million microplastics [...]
