Bryophyte community responses to long-term warming manipulations vary greatly between contrasting tundra habitats
Published: 2026-08-19
Subjects: Life Sciences
Bryophytes are a diverse group of plants, both taxonomically and functionally. Although they are a major vegetation component in many tundra habitats and affect ecosystem function in various ways, they have not received full attention in studies on responses of tundra plant communities to climate warming. Here we compared bryophyte community structure, taxonomic composition, diversity and [...]
Sleep elasticity: accessory, useful and vital components of a single state
Published: 2026-08-19
Subjects: Biology, Ecology and Evolutionary Biology, Evolution, Neuroscience and Neurobiology, Systems Biology
Sleep is universal, homeostatically defended and apparently costly, and for half a century this combination has been read as evidence of a vital, conserved function still awaiting identification. The search has not converged. Instead, it has accumulated a dozen candidate functions, each defensible but none commanding assent. I argue that the difficulty lies with the question rather than with the [...]
Non-native plants homogenize global urban flora
Published: 2026-08-19
Subjects: Ecology and Evolutionary Biology
Urban areas serve as hubs for non-native plant introductions, but the extent to which these introductions have homogenized city floras globally remains unexplored. We analyzed species inventories from 553 cities across six continents and show that non-native plants increase mean pairwise floristic similarity by ~50%, from a Jaccard index of 0.11 for native species alone to 0.16 when non-natives [...]
Wolf–Deer Camera-trap Detections Across Wisconsin’s Statewide Wolf Range (2018–2025): A Temporary Increase in Wolves Following Deer After the 2021 Wolf Harvest, Displacement Effects by Habitat Zone, and Avoidance of People Across Co-occurring Species
Published: 2026-08-19
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Two prior analyses of wolf-enriched extracts of the Snapshot Wisconsin camera network — one county, then five northwestern counties — showed that gray wolves (Canis lupus) tended to arrive at cameras shortly after white-tailed deer (Odocoileus virginianus), that they arrived after antlered bucks more often than the bucks’ numbers would predict, and that deer returned to a site more slowly after a [...]
Protecting confidential data when using AI coding assistants: A practical guide
Published: 2026-08-18
Subjects: Life Sciences
Generative artificial intelligence (AI) coding assistants can substantially accelerate research workflows in ecology, fisheries science, and related quantitative disciplines, but they also create new pathways for accidental or adversarial disclosure of confidential information. Researchers in these fields routinely work with legally protected and commercially sensitive records (e.g., [...]
IUCN Red List Threatened Bird Classification from Citizen-Science Images using Fine-Tuned CNN Features and a Hierarchical Lightweight Classifier
Published: 2026-08-18
Subjects: Artificial Intelligence and Robotics, Biodiversity, Ecology and Evolutionary Biology, Ornithology
To prevent bird strikes at wind farms, an approaching protected bird must be identified so that the turbine can be halted before a collision. We present a bird-species classification module intended for that real-time, low-power edge setting: a hierarchical system assigning IUCN Red List categories to in-the-wild citizen-science bird images, combining a ResNet50 feature extractor fine-tuned on a [...]
Connecting Habitats: Wildlife Occupancy Across the Satpura-Pench Corridor
Published: 2026-08-18
Subjects: Life Sciences
The Satpura–Pench Corridor (SPC) is one of the most important wildlife linkages in Central India, connecting the Satpura and Pench Tiger Reserves, and facilitating the movement and persistence of tigers and other large mammal meta-populations across the Central Indian landscape. However, habitat fragmentation, infrastructure development, mining, agricultural expansion, and other anthropogenic [...]
Toward a standardized workflow for pre-processing large vegetation-plot databases
Published: 2026-08-17
Subjects: Bioinformatics, Botany, Ecology and Evolutionary Biology, Forest Sciences
Large vegetation-plot databases have opened unprecedented opportunities for investigating vegetation patterns and processes across large spatial and temporal scales. However, such databases are typically created by combining pre-existing smaller databases or datasets that often used different standards and protocols, leading to data inconsistencies (e.g., different taxonomy and nomenclature) and [...]
The knowledge landscape of jaguar science: rapid growth, thematic structure, and regional inequalities
Published: 2026-08-17
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences
Understanding how scientific effort is distributed is essential for evaluating the evidence available to guide species conservation. We assessed the temporal, thematic, methodological, and spatial organization of jaguar (Panthera onca) research across the species’ range. Using 1,028 bibliographic records, we applied a metadata-based scope filter, defining a primary analytical corpus of 857 [...]
Marine holobionts: a model arena for host–microbe biology, from ecosystem function to biotechnology
Published: 2026-08-14
Subjects: Life Sciences
Microbial symbioses are the operating system of marine biology. Nearly every macroscopic organism in the ocean exists as a holobiont, the consortium composed of a eukaryotic host and its bacterial, archaeal, microeukaryotic and viral partners. Marine holobionts span a broader range of the metazoan tree of life than likely any other ecological setting on the planet. This breadth makes the marine [...]
Density dependence buffers natural populations against multiple stressors
Published: 2026-08-14
Subjects: Ecology and Evolutionary Biology, Life Sciences
Predicting population persistence under global change requires understanding how populations buffer against interacting stresses. Gradual stresses, such as droughts, suppress individual performance, whereas abrupt stresses, such as harvesting, remove individuals from populations. Because these stresses interact through density-dependent responses of growth, reproduction and survival, predicting [...]
How ecology can trap evolution under climate change
Published: 2026-08-14
Subjects: Life Sciences
Ecological responses to climate change, including plasticity, behaviour, demography, and interactions, can actively trap evolutionary trajectories, not simply facilitate or impede adaptation. Despite growing interest in eco-evolutionary dynamics under climate change, we lack a framework for predicting when ecological change reshapes evolutionary responses. Here, we propose three modes of [...]
Neuroactive pollution alters shoaling in fish, but group phenotype matters
Published: 2026-08-14
Subjects: Life Sciences
Collective behavior governs how animal groups evade predators, forage, navigate, and share information. Yet it is rarely the focus of research on human-induced environmental change, particularly in the case of chemical pollution. Here, we show that exposure to the common neuroactive pollutant temazepam disrupts shoaling dynamics in fish (Poecilia reticulata), with effects shaped by group [...]
Cold adaptation in mammals: mechanisms and genomic insights from bats
Published: 2026-08-14
Subjects: Evolution, Genetics, Physiology
Cold environments impose strong energetic constraints on mammals, driving adaptations including thermogenesis, insulation and torpor. Bats are the only mammals capable of powered flight and inhabit different climates, yet the evolutionary basis of their cold tolerance remains poorly understood. In this study, we screened 571 records and retained 137 studies on mammalian cold adaptation. While [...]
