Transposable elements as drivers of reproductive isolation: A framework for testing hybridization-induced escalation of genetic conflicts
Published: 2026-02-26
Subjects: Evolution, Genetics, Genomics, Other Ecology and Evolutionary Biology
Contrary to long-held views, the exchange of genetic diversity between species by hybridization is now recognized as an important process contributing to the evolution of biodiversity. However, hybridization has molecular consequences beyond the exchange of genetic variation. The clash of divergent genomes upon hybridization can escalate genetic conflicts previously resolved in parental species – [...]
The Individualised Niche in Motion; quantifying individualised niches with movement data
Published: 2026-02-26
Subjects: Aquaculture and Fisheries Life Sciences, Behavior and Ethology, Evolution, Ornithology, Other Animal Sciences, Other Ecology and Evolutionary Biology, Population Biology, Terrestrial and Aquatic Ecology, Zoology
Individuals of the same species often differ consistently in their use of resources, their responses to environmental gradients, and their movement decisions. Between-individual variation across niche axes has been shown to have important ecological consequences. Yet practical frameworks that translate modern tracking data into operational, comparable measures of niche individual specialisation [...]
Beyond Observed Diversity: A Completeness-Based Invasion Theory
Published: 2026-02-26
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology, Terrestrial and Aquatic Ecology
Charles Elton proposed that species-rich communities resist invasion better, but support is mainly from local studies, possibly because studies use observed richness alone, ignoring the dark diversity. I propose Completeness-Based Invasion Theory, linking invasibility inversely to community completeness, an index linking observed and dark diversity, enabling unified insights across scales.
Influence of fire history on reproductive traits in a congeneric obligate seeder and facultative resprouter tree species
Published: 2026-02-20
Subjects: Other Ecology and Evolutionary Biology, Plant Sciences
In fire-prone regions globally, evolution of plant traits that confer resilience to historical fire regimes is widespread. However, many common plant species are currently declining due to a mismatch between historical and contemporary fire regimes. These changes threaten long term community trajectories of plants and the animal species relying on them for food or habitat. Understanding plant [...]
Composite virulence: useful metric or conceptual trap?
Published: 2026-02-20
Subjects: Animal Diseases, Animal Experimentation and Research, Animal Sciences, Biodiversity, Biology, Ecology and Evolutionary Biology, Evolution, Immunity, Immunology and Infectious Disease, Immunology of Infectious Disease, Immunopathology, Life Sciences, Medical Microbiology, Microbiology, Other Ecology and Evolutionary Biology, Other Immunology and Infectious Disease, Parasitic Diseases, Parasitology, Pathogenic Microbiology, Plant Pathology, Research Methods in Life Sciences, Zoology
Virulence, the harm an infection causes to its host, is a cornerstone concept in ecology and evolution, yet it remains difficult to quantify because infection impact is multidimensional, dynamic, and context-dependent. Infections can reduce host performance through multiple, partially redundant routes (including mortality, fecundity loss, behavioural impairment, and physiological disruption), [...]
Maximum performance, repeatability, and intraindividual variability of sprinting in common wall lizards (Podarcis muralis)
Published: 2026-02-17
Subjects: Animal Sciences, Comparative and Evolutionary Physiology, Integrative Biology, Other Ecology and Evolutionary Biology, Zoology
The repeatability of functional traits like physiological maxima (maximum performance) measures the reliability of underlying measurements. However, best practices for analyzing maximal performance while accounting for within-individual variation are lacking. Here, we quantify the coefficient of variation and repeatability of maximum sprinting speed in common wall lizards (Podarcis muralis) from [...]
Social organisation predicts lifespan in mammals
Published: 2026-02-17
Subjects: Ecology and Evolutionary Biology, Evolution, Other Ecology and Evolutionary Biology, Population Biology
1. Recent comparative analyses have identified positive associations between social organisation and longevity in mammals, but independent replication with larger datasets is needed to establish the robustness of this pattern. 2. Here, we analysed maximum recorded lifespan, body mass, and social organisation data for 1,436 mammal species using Bayesian phylogenetic comparative methods, confirming [...]
Should hunters fear the wolf? Effects of wolf recolonization on ungulate harvests in a multi-species European landscape
Published: 2026-02-10
Subjects: Biodiversity, Other Ecology and Evolutionary Biology, Population Biology, Zoology
1. The recolonization of European landscapes by the gray wolf Canis lupus raises questions about the ecological effects of predators and their impact on human interests such as large-game hunting bags, leaving room for alarmism among hunters. 2. We investigated the impact of wolf on recreational hunting by using long-term (2006-2023) and high-resolution (234 hunting districts) hunting bag data on [...]
The overlooked small terrestrial mammal taxa (Rodentia, Eulipotyphla, and Lagomorpha) in the evolution of coronaviruses
Published: 2026-01-28
Subjects: Ecology and Evolutionary Biology, Evolution, Genetics and Genomics, Life Sciences, Molecular Genetics, Other Ecology and Evolutionary Biology
Coronaviruses have been extensively detected in bats over the past few decades. However, increasing evidence suggests that other taxa, such as Rodentia, Eulipotyphla, and Lagomorpha, may have played a significant role in the ecology and evolution of some coronaviruses. Here, we compile recent contributions illuminating these mammals' enigmatic role in coronavirus evolution. We highlight how [...]
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 [...]
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 [...]
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’ [...]
Comparing mean species abundance and the biodiversity intactness index to guide robust biodiversity investment decisions
Published: 2025-12-16
Subjects: Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology
1. Mean species abundance (MSA) and the biodiversity intactness index (BII) are two leading biodiversity metrics used to quantify how species composition differs between a control site and an impacted site. Both are proposed for global biodiversity monitoring, are used by companies to create corporate biodiversity impact accounts, and are being considered by financial institutions seeking to [...]
Ant mutualists as a biotic interaction filter of flowering plant colonization on islands
Published: 2025-12-15
Subjects: Other Ecology and Evolutionary Biology
Aim: Oceanic island floras are well-known for their disharmonic assemblages, with certain taxa and functional groups being over- or underrepresented compared to their source pools, due to effects of dispersal, environmental filtering, and biotic interactions. However, the role of biotic interactions in generating this disharmony remains poorly explored. Location: Global islands. Time Period: [...]
