Psilocybin and the Evolutionary Significance of Altered Neural States: Interaction-Based Perspectives Beyond Deterrence Models
Published: 2026-01-28
Subjects: Behavioral Neurobiology, Ecology and Evolutionary Biology, Evolution, Life Sciences, Neuroscience and Neurobiology, Other Ecology and Evolutionary Biology
Psilocybin is a psychoactive tryptamine produced by a phylogenetically discontinuous yet ecologically diverse subset of fungi. Despite decades of chemical, pharmacological, and ethnobiological research, the evolutionary forces driving the emergence and persistence of this compound remain insufficiently explained. Recent hypotheses proposing that psilocybin evolved primarily as a deterrent against [...]
Reversing the gaze on nature in an era of technological innovation
Published: 2026-01-27
Subjects: Ecology and Evolutionary Biology, Geography, Social and Behavioral Sciences
How nature is understood and ‘seen’ by governing institutions influences how it is managed. The rise of new digital and remote sensing technologies has reinforced a global gaze ‘from above’ that separates the seer from the people and places seen. This gaze has generated critical data on global climate and biodiversity trends and informed ambitious environmental targets. Yet it also obscures a [...]
Diversity in viral resistance emerges from host genotype and infection order effects
Published: 2026-01-27
Subjects: Ecology and Evolutionary Biology, Life Sciences, Plant Pathology, Virology
• While viruses are predicted to be the most diverse group of parasites wild plant hosts encounter, the extent and mechanisms maintaining viral resistance diversity remains poorly understood. Here, we test the hypothesis that allocation trade-offs maintain genetic variation in viral resistance and assess whether phenotypic resistance variation may may arise from altered expression under multiple [...]
Is within-host viral community assembly shaped by local adaptation?
Published: 2026-01-27
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences, Virology
Host-parasite coevolution describes the continuous reciprocal selection driving host defense and parasite infectivity, with direct consequences for disease dynamics. While abundant evidence exists for coevolution shaping host-parasite dynamics within the ‘one host-one parasite’ framework, hosts are typically infected by multiple parasites and the extent to which coevolutionary processes shape [...]
Shared acoustic manifolds for exploratory comparison of passerine vocalizations
Published: 2026-01-23
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Research Methods in Life Sciences
This study presents a fixed-parameter pipeline designed to support reproducible embedding of frame-level representations of multiple passerine vocalizations within shared low-dimensional spaces. Three passerine species are considered: Eurasian Wren, Tree Pipit and Common Chaffinch, with a selection of four individuals for each species group. Vocalization frames from each species group are mapped [...]
Emergent functions in the chemodiversity landscape
Published: 2026-01-23
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
Nature produces countless metabolites that regulate organismal performance and the functioning of ecosystems. Specialised metabolites are particularly diverse and mediate ecological interactions across all geographic scales and levels of biological organisation. While chemodiversity, i.e., the richness, relative abundance and disparity of specialised metabolites within a blend of metabolites, has [...]
Inspiring systematic inclusion of individual animal states to enhance the quality of research
Published: 2026-01-23
Subjects: Animal Sciences, Behavior and Ethology, Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Other Animal Sciences, Other Ecology and Evolutionary Biology, Population Biology
Studies on animals continue to attract criticism over data quality, reproducibility and generality of findings, yet one source of variation remains rarely addressed: differences in individuals’ affective states. In this paper, we suggest that evaluating affect should be considered standard good practice in ecological and behavioural research with wild animals, alongside familiar variables such as [...]
Seasonal camouflage as a model to understand the scope for rapid adaptation in a changing world
Published: 2026-01-23
Subjects: Biodiversity, Ecology and Evolutionary Biology, Molecular Biology
Human-driven environmental change is reshaping ecosystems and challenging species’ ability to adapt. Understanding how genetic variation enables adaptation is crucial for conservation and requires exemplary systems to test hypotheses and make predictions. One particularly suitable model for studying climate-driven adaptation is seasonal color change (SCC), a phenological trait in which [...]
Volcanic deposits select for woodiness on islands
Published: 2026-01-23
Subjects: Ecology and Evolutionary Biology, Life Sciences
Oceanic islands’ unique biodiversity often arises from woody plant radiations derived from non-woody continental ancestors. Since Darwin, various theories have tried to explain the evolution of woodiness on islands (insular woodiness). Recently, frequent volcanic activity and burial of vegetation by volcanic ash (tephra) depositions were linked to the abundance of woody species on islands. In a [...]
Supporting wildlife movement amid the rise of border infrastructure
Published: 2026-01-21
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Law, Environmental Studies, Forest Management, Nature and Society Relations, Zoology
Transboundary areas of conservation importance affected by border infrastructure and militarization urgently need connectivity conservation solutions. Where human conflicts are ongoing and peace initiatives may be unviable, smaller-scale approaches can still be implemented. We propose a multi-faceted approach to support animal movement and minimize impacts of multiple border barriers on medium to [...]
Scaling from Metawebs to Realised Webs: A Hierarchical Approach to Network Ecology
Published: 2026-01-21
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Ecological networks provide a critical framework for understanding the architecture of biodiversity and predicting ecosystem responses to environmental change. However, the application of network ecology is often hindered by a lack of clarity regarding the assumptions inherent in different network representations. Here, we present a hierarchical framework that distinguishes between ‘metawebs’ [...]
The missing branches of the bee Tree of Life: addressing global Darwinian shortfalls and their drivers
Published: 2026-01-21
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Understanding the Darwinian shortfall (i.e., the lack of knowledge about phylogenetic relationships) can help us to guide future biodiversity research and conservation efforts. Overcoming this shortfall is essential to develop robust strategies to preserve the Tree of Life while facing the ongoing biodiversity crisis. Here, we present the first global assessment of Darwinian shortfalls and their [...]

Yet expectations for credible [...]
Developmental density shapes adult mate guarding strategies in an invertebrate
Published: 2026-01-19
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Entomology, Evolution, Life Sciences
Post-copulatory mate guarding is a widespread reproductive strategy that reduces sperm competition but can generate sexual conflict when male and female optima diverge. While mate guarding is known to respond plastically to immediate social conditions, the extent to which early-life social environments of both sexes shape adult guarding behaviour remains poorly understood. We experimentally [...]
