Density-dependent body-size distributions reveal populations state relative to carrying capacity
Published: 2026-09-09
Subjects: Ecology and Evolutionary Biology
Phenotypic traits may provide accessible information about population dynamics, but how population-level trait distributions change along density-dependent trajectories remains poorly understood in populations with complex life cycles. Here, we quantified body-size distributions in three experimental populations of the bulb mite (Rhizoglyphus robini) as they increased from low density towards [...]
Allee effects in corals during fertilisation
Published: 2026-09-09
Subjects: Ecology and Evolutionary Biology, Life Sciences, Population Biology
Allee effects – where individual fitness declines at low population densities or sizes – are pivotal in shaping the reproductive ecology of broadcast-spawning corals. In these species, successful external fertilisation requires that gametes remain at sufficiently high concentrations for long enough periods before turbulent water movement disperses them below fertilisable levels. As reefs degrade [...]
Scenario-dependent functional connectivity in a crowded seascape: habitat suitability, shipping pressure and marine infrastructure in the North Sea
Published: 2026-09-09
Subjects: Biodiversity, Bioinformatics, Ecology and Evolutionary Biology, Life Sciences, Marine Biology
Marine spatial planning increasingly needs seascape connectivity evidence to balance biodiversity conservation, offshore energy development and shipping. However, predicted functional connectivity depends strongly on how habitat suitability and human-use pressures are translated into resistance surfaces. This study tested how shipping and marine infrastructure alter HSM-derived connectivity [...]
Plasticity and subfertility at the evolution of eusociality: an empirical test of the evolution of role specialisation
Published: 2026-09-08
Subjects: Ecology and Evolutionary Biology
At the origin of eusociality, some individuals (workers) gave up reproducing to help another individual (queen) raise their offspring. In Hymenoptera, females are just as related to their siblings as they are to their own offspring meaning only a small benefit of role specialisation is required for selection to favour this strategy. However, it is yet to be established what conditions promoted [...]
A curated bioacoustics dataset of European bat vocalizations
Published: 2026-09-08
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Zoology
Acoustic surveys represent the primary method for monitoring bat populations and assessing their habitat use, yet reference recordings and associated metadata remain fragmented across repositories, recording programs, and private collections. We present ChirosetEurope, a curated dataset of European bat vocalizations (echolocation and social calls) assembled from multiple open repositories and [...]
The reported decline in bird diversity tracks birdwatching effort, not birds
Published: 2026-09-06
Subjects: Ecology and Evolutionary Biology, Life Sciences
A recent analysis in Science links a photovoltaic policy-stringency index to citizen-science bird records aggregated to county-months and concludes that China’s solar-expansion policy reduced Shannon diversity by 2.10% per standard deviation of stringency. Reproducing that estimate exactly from the replication package and checking its inputs against record-level data from the same platform, we [...]
Meta-analysts must lead by example and embrace all FAIR principles
Published: 2026-09-05
Subjects: Ecology and Evolutionary Biology
Meta-analyses rely on comprehensive reporting of results and data in primary studies. They should therefore also strive for exemplary reporting and follow FAIR principles (Findable, Accessible, Interoperable, Reusable) for data sharing. Yet, despite growing calls for open, reliable, and transparent science, the quality, reporting and FAIRness of meta-analyses in ecology, evolution, and [...]
Assessing habitat associations of critically endangered big-headed turtles to support grassroots river conservation
Published: 2026-09-05
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Modern wildlife conservation relies primarily on state-run protected areas and hunting regulations, whereas grassroots initiatives to protect ecosystems from various threats such as large-scale infrastructure development are underrecognized and receive limited scientific support. We studied critically endangered big-headed turtles (Platysternon megacephalum) to support a grassroots river [...]
From population trends to biodiversity changes: synthesizing multi-species signals of collapse
Published: 2026-09-05
Subjects: Biodiversity, Ecology and Evolutionary Biology
Taking the pulse of biodiversity is no small feat, and abundance time series are some of the most valuable data we have to measure change. Biodiversity changes are often complex, with some species declining while others grow, leading to a reorganisation of the network of interactions between species. The infamous decline of Atlantic cod in the Newfoundland shelf groundfish community between 1981 [...]
Social transmission of fear is disrupted by pharmaceutical pollution
Published: 2026-09-04
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology
Social information transfer enables rapid responses to threats and underpins collective predator avoidance across taxa. Yet whether the growing threat of environmental pollutants, such as pharmaceuticals, disrupt this process remains unknown. Here, we show that the widespread antidepressant pollutant amitriptyline disrupts fear contagion—the automatic matching of an individual’s behavioural state [...]
Temperature extremes in the Gulf of Maine: A synthesis of marine heatwaves, cold-spells, and ecological impacts
Published: 2026-09-04
Subjects: Ecology and Evolutionary Biology, Marine Biology, Oceanography and Atmospheric Sciences and Meteorology
Long-term environmental change has been altering ecosystem function and phenology globally. Short-term temperature pulses, often called extreme temperature events, can accelerate impacts of long-term change on ecosystems by forcing rapid changes in food webs, triggering range shifts, and disrupting reproductive cycles. Marine ecosystems at the confluence of large global currents are particularly [...]
Populations of cooperatively breeding birds are buffered against annual variation in precipitation and temperature
Published: 2026-09-01
Subjects: Ecology and Evolutionary Biology
Cooperative breeding is a reproductive system wherein other than parents care for offspring. It has been suggested to provide advantages in harsh and unpredictable climates. Support for this idea stems from detailed population studies, or phyla-wide comparative studies, but both approaches are insufficient to assess the demographic benefits of cooperative breeding. Here, we use abundance [...]
What’s in flower? Phenological temperature sensitivities in a restricted alpine flora
Published: 2026-09-01
Subjects: Ecology and Evolutionary Biology, Life Sciences, Plant Sciences
As climate warming continues, cues for shifts in plant reproductive timing will be a key mediator of species success. To examine the links between temperature and flowering time in the Australian alpine, we used climate records and 18,000 flowering observations spanning 12 years for 52 alpine plant species from the Snowy Mountains, Australia. We modelled three phenological traits (flowering [...]
wildtag.ai: an open-access end-to-end offline AI-assisted desktop application for managing camera trap projects

1. Camera traps generate massive volumes of data, yet their decision-support potential is diluted by the bottleneck of manual processing. Automated classification has largely solved this, but classification alone does not remove the barriers to adoption: it must be coupled with the means to turn predictions into a verified, shareable dataset, which no existing tool does end-to-end, offline, and [...]
Sex-specific divergence in microhabitat use and activity patterns in fire salamanders: temperature matters
Published: 2026-09-01
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Zoology
Human-driven climate change and habitat degradation cause alterations in the spatial and temporal availability of natural resources, forcing wildlife to adjust their interactions with the environment in order to survive. To identify changes and promote effective conservation measures within the limited suitable habitats available, it is crucial to better understand habitat use. Activity patterns [...]
