A framework for understanding how and why animals die
Published: 2026-01-19
Subjects: Biology
Mortality is a fundamental demographic process that shapes both populations and ecological communities. Yet, how and why animals die is just as important as the simple fact of whether or not they do. A richer understanding about drivers of death across taxa is needed to advance ecological theory and to improve conservation practice. Both require identifying the causal pathways that lead to death; [...]
Phylogenetic Perspectives on Heavy Metal Hyperaccumulation in Fungal Lineages
Published: 2026-01-19
Subjects: Biology, Environmental Microbiology and Microbial Ecology Life Sciences, Forest Sciences, Life Sciences, Other Microbiology, Other Pharmacology, Toxicology and Environmental Health
Across the fungal kingdom, the ability to hyperaccumulate and sequester toxic heavy metals from the environment appears to have evolved multiple times. Although in plants, animals, and bacteria the evolution of heavy metal hyperaccumulation is well studied, and despite potential applications of hyperaccumulation in mycoremediation, fungi are under-investigated. Here, we compile a novel dataset [...]
The interplay between epigenetic mechanisms and deleterious mutations: implications for fitness, evolution and conservation
Published: 2026-01-13
Subjects: Biology, Ecology and Evolutionary Biology, Genetics, Genetics and Genomics, Genomics, Life Sciences, Molecular Genetics
Understanding the causal effects of genetic mutations is essential for explaining fitness variation, forecasting evolutionary trajectories and assessing extinction risk, yet remains a fundamental challenge, particularly in natural populations. While amino acid substitutions can alter protein structure and function, mutations affecting gene regulation can also have significant fitness [...]
Bridging Science and Policy: A Global Review of Socio-ecological Indicators Guiding Biodiversity Action
Published: 2026-01-13
Subjects: Biology, Community-based Research, Environmental Monitoring, Human Ecology, Life Sciences, Natural Resources and Conservation, Nature and Society Relations, Other Political Science, Remote Sensing, Spatial Science, Sustainability
1. Biodiversity continues to decline despite a proliferation of indicators intended to inform conservation policy. We asked which socio-ecological indicators are actually reaching decision-makers, how they are used, and where critical gaps persist. 2. Following a scoping-review protocol and PRISMA workflow, we screened 906 documents in Web of Science and Scopus and analyzed 43 studies that [...]
Neuroethology of Corpse-Directed Behaviors in Bees
Published: 2026-01-02
Subjects: Biology, Life Sciences
Across taxa, social animals inevitably encounter dying or dead conspecifics and respond in patterned ways, yet the mechanisms underlying these behaviors remain understudied. Bees offer a powerful comparative system for exploring the neuroethology of corpse-directed behaviors. Across the bee phylogeny, sociality has been gained and lost multiple times, resulting in species that range from solitary [...]
Evaluating the vulnerability of critical early life stages in plants during heat extremes
Published: 2025-12-31
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Plant Sciences
Plants, their seeds, and their gametes show remarkable resilience and responsiveness to environmental conditions. However, worsening climate change with more severe and frequent extreme climatic events, like heatwaves and hot droughts, will likely push beyond physiological limits of many species. If such events occur during important points of development and reproduction – rather than mature [...]
An analysis of passerine egg traits across the city mosaic: Urbanisation does not affect egg size and pigmentation patterns
Published: 2025-12-24
Subjects: Animal Sciences, Biology, Life Sciences, Zoology
1. Rapid urbanisation provides remarkable opportunities to study how sudden, extreme changes impact wildlife. Compared to natural areas, cities are characterised by factors affecting both abiotic (e.g. climate, pollution, habitat fragmentation) and biotic (e.g. Normalized Difference Vegetation Index (NDVI), species composition, phenology) components of the ecosystem, ultimately changing the [...]
Interactive effects between drought and warming in field manipulative experiments across grasslands globally: a systematic review and meta-analysis
Published: 2025-12-23
Subjects: Biology
Aim Interactions between temperature and moisture are possible whereby increases in temperature can result in decreases in soil moisture, exacerbating drought conditions. Both uptake by and emission of carbon from grassland ecosystems are, in large part, governed by temperature and moisture. It is unclear how grasslands will respond to concurrent warming and drought conditions in the future [...]
Social structure in northern bottlenose whales: Stable relationships without stable groups
Published: 2025-12-23
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Marine Biology
Uncovering the drivers and function(s) of social relationships across a wide range of species is key to understanding the ecology and evolution of social behaviour. Northern bottlenose whales have been identified as a particularly important case study for social evolution. Unlike other large, toothed whale species which live in kin-based social units, northern bottlenose whales appear to form [...]
Coevolution of social network structure and life history in toothed whales
Published: 2025-12-18
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Evolution, Marine Biology
Toothed whales offer a 34 million year-long natural experiment for the evolution of complex mammalian societies. However, quantitative comparative analyses of social structure in these species are lacking. Here, we draw on existing social network analyses to compare social structure across toothed whales. We consider published measures of two social network traits across all toothed whales: [...]
Moving Target(s): One Health at changing human-livestock-wildlife interfaces in tropical ecosystems
Published: 2025-12-18
Subjects: Animal Sciences, Biodiversity, Biology, Ecology and Evolutionary Biology, Food Science, Life Sciences, Systems Biology
One Health approaches currently conceptualized for Western landscapes require fundamental rethinking for tropics, where human-livestock-wildlife interfaces exist as variegated mosaics rather than discrete zones. This overview examines why tropical ecosystems involve (i) Human mobility patterns shifting continuously through rural-urban migration and globalization (ii) Livestock health [...]
Behavioural repertoire and the onset of precocious sexual behaviours in juvenile ruffs (Calidris pugnax)
Published: 2025-12-10
Subjects: Animal Studies, Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Life Sciences
Adult phenotypes are shaped by developmental processes during early life. This also applies to reproduction and dominance-related behaviours before maturation, called precocious sexual behaviours. However, beyond largely anecdotal reports, the onset of such behaviours is rarely studied. Here we document the development of precocious sexual behaviours in the ruff Calidris pugnax, a lekking [...]
Tagged for life? Retention rates and effects on growth and condition of tagging - a long-term field study on PIT- and Carlin tagging in European eel
Published: 2025-11-28
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Different types of tags and markers are commonly used for various fish monitoring and tracking purposes. Effects of tags and markers on fish and the retention rates can affect the interpretation of mark-recapture data on both the individual (e.g. growth and body condition) and population level (e.g. survival and pro-duction estimates), making studies of this issue important. In this study, we [...]
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 [...]
