The promise and challenge of environmental epigenomics in a rapidly changing world
Published: 2026-04-22
Subjects: Animal Sciences, Biology, Environmental Studies, Genetics and Genomics, Life Sciences, Research Methods in Life Sciences
There has been a fast-paced research effort on the role of epigenetic mechanisms in facilitating organisms’ capacity to cope with rapid environmental change, highlighted by several recent reviews and special issues on this topic. What is important, along with this momentum, is to pause and reflect on both the promises and challenges of linking detailed molecular mechanisms to broad patterns of [...]
Reliable inference: benefits of open raw data may be universal in meta-analysis
Published: 2026-04-22
Subjects: Ecology and Evolutionary Biology, Life Sciences
While the benefits of open data are often discussed, they are rarely quantified. Here, we provide the first evidence of the potential gains from using raw data for evidence synthesis and introduce a tool that helps researchers determine when this approach is most beneficial. Classical meta-analysis (CMA) relies on published results, making it vulnerable to publication bias and p-hacking. We [...]
TOCing with birds: Touchscreen-equipped operant chambers as flexible tools for avian behavioral experiments
Published: 2026-04-22
Subjects: Life Sciences
1. Understanding how animals respond to visual stimuli is a key goal of behavioral and evolutionary ecology. Experiments documenting the behavioral responses of receivers to different stimuli are an essential explanatory tool, yet presenting stimuli that engage in complex but controlled animal behaviors – such as naturalistic movement – to biologically relevant receivers remains a significant [...]
Plastic shifts in thermal preference and thermoregulation strategy across ontogeny in an invasive fly
Published: 2026-04-21
Subjects: Animal Sciences, Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Entomology, Life Sciences, Other Ecology and Evolutionary Biology, Zoology
Behavioural thermoregulation allows ectotherms to escape extreme or seek optimal temperatures. Its precision can impact survival and fitness under changing conditions and its plasticity can be an adaptive strategy when the plasticity of thermal limits is insufficient to buffer against warming. We explore the developmental and intergenerational plasticity of behavioural thermoregulation strategies [...]
Rethinking terrestrial wildlife telemetry through instrumentation without capture and handling
Published: 2026-04-21
Subjects: Life Sciences
Telemetry using animal‑borne biologgers is central to wildlife research. Capturing and instrumenting wild animals, however, remains the most invasive, logistically challenging, and costly component of telemetry studies. This has contributed to current practice, which favors long tracking durations on few individuals, prioritizing longevity over temporal detail. While this model has yielded [...]
Autonomous biodiversity credits on the horizon?
Published: 2026-04-21
Subjects: Biodiversity, Life Sciences, Population Biology
Biodiversity credits are being pushed as a means to fund nature conservation. Much of the debate around credits has concerned additionality, leakage, and permanence, and the extent to which biodiversity can be captured in an individual unit. As AI models continue to develop, however, technology could create a new kind of loss-of-control problem for biodiversity credits. In this Perspective, we [...]
Sociality beyond helpers at the nest: the number of strong associations predict reproductive trade-offs in a cooperative breeder
Published: 2026-04-21
Subjects: Life Sciences
Individual social relationships can shape fitness across taxa, but in studies on cooperatively breeding species, the social environment relevant to reproduction is typically reduced to the number of helpers. We tested whether breeder sociality beyond helper number predicts reproductive performance in a colonial cooperative bird, the sociable weaver (Philetairus socius). Using long-term data and [...]
First record of Poa cf. annua on Fildes Peninsula (King George Island), a major human-access node in Antarctica
Published: 2026-04-17
Subjects: Biodiversity, Ecology and Evolutionary Biology
Antarctic terrestrial ecosystems are highly species-poor and particularly vulnerable to biological invasions. Poa annua L. is the only non-native flowering plant known to have established a persistent, self-sustaining population in Antarctica, with confirmed occurrences on King George Island near the H. Arctowski Polish Antarctic Station and the Ecology Glacier forefield. Here we report a new [...]
Ecosystem condition assessments: A context-specific workflow to integrate local expert knowledge and remote sensing
Published: 2026-04-17
Subjects: Life Sciences
Despite decades of conservation science, we still struggle with a deceptively simple question: how do we know if an ecosystem is in good or poor condition? We present a reproducible, six-step workflow for assessing ecosystem condition using remote sensing, ecological knowledge, and expert validation. The approach is designed to be applied consistently across diverse biomes, while remaining [...]
Evolutionary arms race between transposable elements and human genes: telomere-to-telomere genome comprehensive analysis identifies young L1 clusters in the interferon-alpha domain
Published: 2026-04-17
Subjects: Life Sciences
Transposable elements (TEs) have played a central role in major evolutionary transitions across the human lineage, from eukaryogenesis to the emergence of the eutherian placenta, and are currently reactivated in cancer and autoimmune diseases. The availability of the complete telomere-to-telomere (T2T) human genome assembly enables comprehensive investigation of TE contributions to gene [...]
Resource abundance can buffer trophic mismatch in a caterpillar-passerine food-chain
Published: 2026-04-17
Subjects: Life Sciences
Phenological mismatch occurs where variation in the magnitude of the response to environmental cues among species disrupts previously synchronised interspecific interactions, posing a risk to ecosystems as the climate changes. Understanding how ecological and environmental factors modulate the fitness effects of mismatch is essential for forecasting its impacts. Here, we analyse trophic mismatch [...]
Aliens Are Likely to Be Smart But Not “Intelligent”: What Evolution of Cognition on Earth Tells Us about Extraterrestrial Intelligence
Published: 2026-04-17
Subjects: Life Sciences
How likely is it that we will find aliens like the ones in so many science fiction stories–people who possess self-awareness and cognitive ability comparable to ours, but who arose from an independent evolutionary origin? Here I make the argument that if life has evolved on other planets, it may well eventually acquire complexity equivalent to that found on Earth. The resulting lifeforms may be [...]
FGMLab: An open-source software for teaching biological evolution through Fisher's geometric model
Published: 2026-04-16
Subjects: Education
The process of biological evolution is typically taught through the lens of population genetics, where students are presented with models and diagrams of how alleles (genetic variants) change in frequency over time. While this convention depicts the underlying genetic basis of biological evolution, it fails to quantitatively illustrate how traits, on which natural selection actually acts, evolve. [...]
Nature-based Solutions for Climate and Disaster Risk Mitigation in SIPLAS: A Framework for Policy Integration and Innovative Financing
Published: 2026-04-16
Subjects: Environmental Studies, Public Affairs, Public Policy and Public Administration, Social and Behavioral Sciences, Urban Studies and Planning
Small island protected areas face compounding pressures from rapid urbanization, constrained land use, biodiversity loss, and intensifying climate and disaster risk, yet scholarship on how to finance and mainstream Nature-based Solutions (NbS) in governance-complex, nationally protected island systems remains limited. This study addresses that gap by examining the integration of NbS into climate [...]
Human Homosexuality, Transsexuality and Evolution: A Critical Appraisal
Published: 2026-04-16
Subjects: Life Sciences
Homosexual behavior occurs naturally in many species of mammals. Among primates, homosexuality is an evolutionary innovation originating when the anthropoid lineage split from the prosimian linage, becoming prominent in socially complex old world primates. Many species possess multiple genders: multiple morphs within each sex. Homosexual behavior and transgender expression occur across all [...]
