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 [...]
An Interpretation, Survey, and Outlook of Microbial Macroecology
Published: 2026-01-28
Subjects: Life Sciences
The construction of a predictive theory of the dynamics and structure of microbial communities requires the consideration of repeatable, robust empirical patterns. The investigation of such patterns in ecology has historically been the domain of the subdiscipline of macroecology. However, the application of macroecology to microorganisms is not straightforward, as there is not a unified view of [...]
SPECIES OF PASSIONATE INTEREST: Practicing Biocultural Conservation and Eco-social Transformation Together
Published: 2026-01-27
Subjects: Life Sciences, Social and Behavioral Sciences
Species of Passionate Interest expands on the concept of the "cultural keystone species," reviewing its intellectual history and proposing future applications in the field of biodiversity conservation. The paper critiques the classic view of the "keystone" species in Western conservation science, emphasizing the need to consider the dynamic cultural context and the diversity of emotional [...]
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 [...]
An open occurrence dataset for European subterranean spiders
Published: 2026-01-27
Subjects: Life Sciences
Spiders are remarkably diverse in caves and other subterranean habitats, where they play key ecological roles as generalist predators and strongly influence local food webs. They have been instrumental as model organisms for testing various eco-evolutionary hypotheses. Furthermore, strictly subterranean species exhibiting narrow ranges and high endemism are particularly significant for [...]
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 [...]
Functional redundancy shapes spatial patterns of vulnerability to climate-driven shifts in plant community composition across Australia
Published: 2026-01-23
Subjects: Life Sciences
Climate change threatens plant communities worldwide with substantial species losses, yet the consequences of reduced diversity for ecosystem functioning remain uncertain. Functional redundancy, where multiple species fulfil similar ecological roles, may provide functional insurance by buffering ecosystem processes against species loss. Here, we combined plant composition data from 646 TERN [...]
Genetic estimates of relatedness: Established practices and new opportunities through low coverage whole genome sequencing
Published: 2026-01-23
Subjects: Life Sciences
Identifying close relatives in wild animal populations is fundamental across many research fields. Genetic estimates of relatedness have expanded rapidly in recent decades, based on various types of genetic data. Here, we review their use and outline opportunities for future studies by combining two complementary approaches. First, we systematically reviewed 2,861 articles to assess how genetic [...]
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 [...]
Body size shapes average behaviour, social impact, and social responsiveness in agonistic interactions
Published: 2026-01-23
Subjects: Life Sciences
Social interactions shape behavioural phenotypes and fitness, and therefore represent major drivers of evolution. Increasingly, it is recognised that plasticity in response to social partners (“social plasticity”) operates through two causal pathways: an individual’s impact on and responsiveness to partner phenotypes. Functional links among an individual’s average behaviour, social impact, and [...]
A framework for predicting the dynamics of plant-mycorrhizal interactions
Published: 2026-01-23
Subjects: Life Sciences
Interactions between plants and mycorrhizal fungi shape nutrient cycling and ecosystem function on a global scale, but the dynamics of these interactions remain poorly understood. Due to their below-ground nature, directly observing key dynamical features such as Allee effects and oscillations is often not possible, hampering further progress in this area. Here we present a mechanistic model of [...]
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 [...]
Laboratory Evidence of the effect of Water Availability on Aedes Mosquito Population Dynamics: A Scoping Review
Published: 2026-01-21
Subjects: Life Sciences
The increasing geographical spread, abundance and activity of invasive Aedes mosquitoes are cause of concern for public health at local and global scales. These species transmit diseases such as dengue, Chikungunya, Yellow Fever, and Zika, which can cause outbreaks in endemic and non-endemic settings. Unlike temperature, whose impact on key entomological traits has been extensively studied, the [...]
