Spatial and environmental influences on the assembly of silk microbiomes in a social spider
Published: 2025-06-03
Subjects: Ecology and Evolutionary Biology, Environmental Microbiology and Microbial Ecology Life Sciences, Life Sciences
In nesting animals, the built environment can play an important role in host-associated microbiome assembly. However, the sources and processes structuring the resulting microbiome remain underexplored. In the social spider Stegodyphus dumicola, philopatric sisters collectively build and maintain a silken nest, capture prey, and exhibit alloparental care. We used S. dumicola as a test system to [...]
Suspended particulates decline along a dense, small-stream mussel bed
Published: 2025-06-02
Subjects: Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology
Water filtration by freshwater mussels is a valued ecosystem service; however, it has not been well studied in natural settings. To examine the potential influence of mussel filtration on suspended particulates, we measured the concentration of Escherichia coli, chlorophyll-a, and total suspended solids along a stream reach with a dense mussel assemblage (Mussel Site) and a stream reach with no [...]
A framework for modelling thermal load sensitivity across life
Published: 2025-06-01
Subjects: Ecology and Evolutionary Biology, Integrative Biology, Life Sciences, Physiology, Systems and Integrative Physiology Life Sciences
Forecasts of vulnerability to climate warming require an integrative understanding of how species are exposed to, are damaged by, and recover from thermal stress in natural environments. The sensitivity of species to temperature depends on the frequency, duration, and magnitude of thermal stress. Thus, there is a generally recognised need to move beyond physiological metrics based solely on [...]
Barriers and opportunities to preventing residential bird-window collisions
Published: 2025-05-31
Subjects: Biodiversity, Community-based Research, Ecology and Evolutionary Biology, Sociology
Collisions with windows are a leading source of avian mortality in North America. Window treatment options are commercially available; however, these solutions are rarely used. To investigate knowledge and perceptions of bird-window collisions, willingness to treat windows, and barriers and solutions to treating windows we conducted a survey of residents in Ottawa, Canada. Of 422 survey [...]
A systematic map of forest disturbance impacts on soil and litter fauna: knowledge gaps and a roadmap for future research
Published: 2025-05-31
Subjects: Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology
Anthropogenic climate change is increasing the frequency and severity of natural disturbances such as fires, droughts, wind damage, and insect and pathogen outbreaks in forests. The impacts of these disturbances on aboveground biodiversity are relatively well known, but this is not true for belowground biodiversity, particularly soil fauna. While a number of syntheses exist summarising the [...]
Herbarium specimens reveal regional patterns of tallgrass prairie invasion and changing species abundance across 130 years
Published: 2025-05-28
Subjects: Biodiversity, Botany, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Plant Biology, Plant Sciences
The spread of non-native species is an acute threat to global biodiversity. However, a lack of long-term, spatially widespread occurrence data has prevented investigation of how multi-species invasions affect native assemblages. We harnessed more than 65,000 digitized herbarium specimens across 522 species to study how relative abundances of native and non-native species have changed since the [...]
Cellular Innovations and Diversity in the Lepidopteran Compound Eye
Published: 2025-05-27
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Entomology, Evolution, Life Sciences, Molecular Genetics
Lepidoptera, having co-diversified with flowering plants and adapted to various diel niches, present a remarkable system for studying compound eye cell type diversity. Here we synthesize the latest research regarding lepidopteran eye evolution across different timescales, from species-level variation to family-level changes, and mechanistic levels, from broad anatomical variation to molecular [...]
IUCN Red List of Ecosystems. Sandy Beaches & Dunes of the West African Transition
Published: 2025-05-22
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences
Abstract The ‘Sandy Beaches and Dunes of the West African Transition’ form a regional ecosystem subgroup along the West African coast. It had a mapped extent of 584 km² in 2022, with a width ranging from 0.012 km to 4.796 km, and stretching over approximately 1321 km. This ecosystem subgroup extends along the shores of Mauritania, The Gambia and Senegal. This ecosystem frequently experiences [...]
Filling Monitoring Gaps for Data-deficient Species Using Annual Occupancy Predictions from Co-occurrence Models
Published: 2025-05-21
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences
Fragmented surveys and limited monitoring exclude most invertebrate species from conservation policy. We present a framework that generates annual occupancy predictions using species distribution models (SDMs) to reconstruct missing trends—not to extrapolate trends, but to fill them in (the fill-in approach). Instead of filtering poor-data regions and years or relying on static environmental [...]
Disordered systems in community ecology: a tutorial
Published: 2025-05-16
Subjects: Ecology and Evolutionary Biology, Other Physical Sciences and Mathematics
A basic fact of community ecology is that most ecosystems are comprised of many species and processes. Mathematical models trying to capture these ingredients and explain empirical phenomena usually face the problem of having vast numbers of unknown parameters and uncertain assumptions. It is not obvious when such mathematical models can truly be quantitatively predictive, or even conceptually [...]
Oxygen supersaturation has negligible effects on warming tolerance in aquatic ectotherms
Published: 2025-05-15
Subjects: Aquaculture and Fisheries Life Sciences, Ecology and Evolutionary Biology, Marine Biology
Under the midday sun when photosynthesizers are producing oxygen, shallow aquatic ecosystems can become supersaturated with oxygen (>100% air saturation) while they simultaneously peak in water temperature. It has been suggested that oxygen supersaturation could protect water-breathing animals from mortality during heatwaves because of the potential role of oxygen in governing thermal [...]

Driven by technological advancements and reduced costs, biologging has seen a rapid growth transforming the study of animal behaviour and ecology. This ``golden era'' of animal tracking provides unprecedented insights into wildlife, aiding conservation efforts and ecological research. However, in the wake of the rapid growth loom pressing ethical and methodological challenges, including a lack of [...]
Pervasive Negative Effects of Leucaena leucocephala (White-Popinac) Invasion on Regenerating Areas of the Atlantic Forest
Published: 2025-05-12
Subjects: Ecology and Evolutionary Biology
The use of invasive species in ecological restoration is controversial and has raised recent concerns. In Brazil, some ecosystem restoration and agroforestry projects have proposed that white-popinac (Leucaena leucocephala (Lam.) de Wit), a broadly distributed invasive species, is a promisor species to be used when the soil is severely altered, based on the premise that it might not necessarily [...]
Is there a relationship between distance to natural habitat and pollination services in tropical smallholder farms? A systematic review and meta-analysis
Published: 2025-05-12
Subjects: Agriculture, Biodiversity, Ecology and Evolutionary Biology, Entomology
Proximity to natural habitat is known to enhance pollination services in agricultural landscapes, particularly in large-scale industrialised farms. However, it remains unclear whether these patterns hold in tropical smallholder farms – ecologically complex landscapes that sustain millions of the world’s most food-insecure communities and depend heavily on biodiversity-derived ecosystem services. [...]
Ecological traits explain wild felid responses to human-modified landscapes in Brazil: an open-data approach for conservation
Published: 2025-05-12
Subjects: Ecology and Evolutionary Biology, Life Sciences
Understanding how wild felids respond to human-modified landscapes is critical for designing effective conservation strategies, yet comparative assessments across species remain scarce in tropical regions. Here, we assess the habitat selection and road sensitivity of nine wild felid species in Brazil using an integrative and scalable framework based entirely on open-access data. We compiled over [...]
