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 [...]
Amphibian communities are structured by local habitat quality in garden ponds and spatial factors in urban ponds
Published: 2026-04-15
Subjects: Life Sciences
Amphibians are among the most threatened vertebrates, and urbanisation contributes to their decline through habitat loss, fragmentation, pollution, and the spread of invasive species. At the same time, urban freshwater habitats, such as ponds, can serve as important refuges within highly modified landscapes. While the role of urban ponds in supporting freshwater biodiversity is increasingly [...]
Heterogeneity in Statistics: A Conceptual and Methodological Review
Published: 2026-04-14
Subjects: Physical Sciences and Mathematics
Heterogeneity—the presence of meaningful variation across observations, in models, and in inferences—is a foundational concept in statistics that has many meanings. This review synthesizes the evolution of the meanings, methodologies, and interpretations of the four dominant and interconnected types of heterogeneity: (1) heteroscedasticity (non-constant variance), historically treated as a [...]
Sample size shapes metabarcoding-driven biodiversity assessments across body sizes in soil
Published: 2026-04-14
Subjects: Biodiversity, Bioinformatics, Life Sciences
Understanding how sample size influences biodiversity detection across taxonomic groups differing in body size is critical for designing robust and cost-efficient metabarcoding studies of soil eukaryotes. Using a soil mass gradient (0.25-32 g) combined with a universal 18S rRNA metabarcoding approach, we quantified how sample mass shapes diversity estimates across eukaryotic taxa. Diversity [...]
