Marine heatwave and keystone predator loss drive broad-scale decline and hinder recovery of a rocky intertidal kelp
Published: 2025-07-22
Subjects: Ecology and Evolutionary Biology, Life Sciences, Marine Biology
Human activities are increasingly driving the co-occurrence of multiple ecological stressors, resulting in interactive and cumulative impacts that can reshape ecosystem dynamics and accelerate population declines of climate-sensitive species. Here, we use over two decades of rocky intertidal monitoring across 17 sites spanning over 1,200 km of coastline to assess how two unprecedented stressors—a [...]
Discrepancies between wolf distribution estimates from opportunistic mortality records and probabilistic field-based surveys
Published: 2025-07-19
Subjects: Ecology and Evolutionary Biology, Other Life Sciences, Zoology
The gray wolf (Canis lupus) has expanded its distribution in Europe, where some countries implemented population monitoring schemes through structured surveys. However, increasing wolf populations has also resulted in a growing number of wolves being found dead each year. Although these opportunistic reports are promising for population monitoring, their accuracy in reflecting wolf distribution [...]
The hidden dimensions of biodiversity
Published: 2025-07-19
Subjects: Ecology and Evolutionary Biology, Life Sciences
Uncovering and describing biodiversity is fundamental to advancing both scientific understanding and public awareness of nature. While many biodiversity facets are visible and even in the spotlight, including those biodiversity features we encounter on a daily basis, much of the world’s biodiversity remains hidden. This review addresses the critical questions: What dimensions constitute hidden [...]
Habitat availability, Jurassic and Cretaceous origins of the deep-bodied shark morphotype, and the rise of pelagic sharks
Published: 2025-07-18
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
Macroevolutionary trends in morphology fundamentally shape our understanding of marine ecosystems through deep time. Sharks (Elasmobranchii: Selachii) have been suggested to broadly exhibit two discrete body forms: one ‘shallow-bodied’ form associated with slow-moving benthic species, and a ‘deep-bodied’ form typified by highly active pelagic taxa. Until now, the validity or evolution of these [...]
Geography of masting synchrony creates more famines than feasts
Published: 2025-07-17
Subjects: Ecology and Evolutionary Biology, Life Sciences
Interannually highly variable and synchronized production of large seed crops by perennial plants, called masting, drives resource pulses and famines with cascading effects on food webs. While the spatial scale of masting synchrony is well documented, it remains unclear how synchrony differs between years of seed abundance and failure, and how such dynamics extend across species and space. These [...]
DrawerDissect: Whole-drawer insect imaging, segmentation, and transcription using AI
Published: 2025-07-15
Subjects: Artificial Intelligence and Robotics, Biology, Ecology and Evolutionary Biology, Entomology, Life Sciences
1. Natural history museums often curate large collections of pinned insects. These collections represent invaluable records of biodiversity information, ecological patterns and phenotypic variation. A common goal of museums is to create digital versions of these records for curation and research purposes. However, traditional methods of specimen imaging and metadata transcription are [...]
Multidimensional microclimate velocities alter the picture of shifting climates in tropical forests
Published: 2025-07-15
Subjects: Ecology and Evolutionary Biology
Climate velocity—the speed and direction species must move to track climate change—is often estimated without accounting for vegetation-driven microclimatic variation. Using airborne lidar data from a tropical montane rainforest, we generated high-resolution 3D maps of topography and canopy structure to mechanistically model near-ground and within-canopy microclimates. Microclimate-derived [...]
okaapi: an R package for generating social networks based on trait preferences
Published: 2025-07-09
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Physical Sciences and Mathematics, Social and Behavioral Sciences
Modelling of simulated networks with generative network models plays a central role for our understanding of the emergence and consequences of network structures. Accessible software that generates simulated networks based on relevant processes can facilitate the use of this important approach in behavioural ecology, and can help drive forward our understanding of animal social structures. Here [...]
Evaluating the role of Zoo Campuses in Wild Snake Body Condition and Ophidiomycosis Risk
Published: 2025-07-08
Subjects: Animal Sciences, Ecology and Evolutionary Biology, Immunology and Infectious Disease, Life Sciences
Abstract.—Snake Fungal Disease (SFD), caused by Ophidiomyces ophidiicola, poses a growing threat to snake populations. This study compared infection prevalence, body condition, and species composition between snakes found at Caldwell Zoo located in Tyler, Texas and those found in surrounding wild areas. While infection rates were similar (14.3% zoo, 12.1% wild), zoo-caught snakes had [...]
Nature restoration legislation means redefining targets and forecasting progress
Published: 2025-07-07
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Nature restoration is at a pivotal moment, driven by global initiatives like the EU Nature Restoration Law and the Kunming-Montreal Biodiversity Framework. These frameworks pose key challenges to how restoration targets are defined to ensure they are not only achievable and measurable but also resilient to future environmental changes. This requires addressing two key challenges: setting [...]
Ungeneralizable generalizations? A meta-meta-analysis of the influence of taxonomic bias on the study of behavior
Published: 2025-07-03
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology
Meta-analysis is a powerful tool for synthesizing behavioral research and identifying general patterns. However, are the conclusions we draw from these analyses truly representative across animal groups? Alternatively, are our conclusions shaped by taxonomic biases in the underlying research? For example, in animal behavior, vertebrates are overrepresented in the research we conduct. This [...]
Bridging the scales: what can microbial ecologists learn from classic ecology?
Published: 2025-07-01
Subjects: Ecology and Evolutionary Biology, Environmental Microbiology and Microbial Ecology Life Sciences, Microbiology
The fields of ecology and microbiology have historically developed independently of one another, resulting in each having unique methods, terminology, and concepts. Microbial ecology aims to synthesise these perspectives, merging the molecular and reductionist strengths of the microbiologist with the systems-level viewpoint of the ecologist. However, unifying disciplines with independent [...]
Body condition as a shared response to environment in a commercially important demersal fish assemblage
Published: 2025-06-28
Subjects: Biology, Ecology and Evolutionary Biology, Marine Biology
Measures of an organism's weight at a given length are often considered reliable indicators of energy reserves or `condition', which can be related to fecundity and risk of mortality. Understanding the impact of environmental change on fish condition may therefore be critical for sustainable management of human activities in marine ecosystems. We investigated how changes in Canadian Pacific [...]
Demographic causes of the pesticide crash in the peregrine falcon
Published: 2025-06-25
Subjects: Ecology and Evolutionary Biology, Life Sciences, Population Biology
Population crashes in many avian predators during the 1950–70s, caused by organochlorine pesticides, belong to the most spectacular cases in the history of conservation and ecotoxicology. Negative effects of DDT on eggshell thickness, leading to egg breakage and declining productivity, are well-documented. In addition, cyclodiene pesticides such as Dieldrin were strongly suspected to contribute [...]
Prompting large language models for quality ecological statistics
Published: 2025-06-24
Subjects: Applied Statistics, Biostatistics, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Large language models (LLMs) are rapidly transforming scientific workflows, including statistical analyses in ecological sciences. While these AI tools offer impressive capabilities for code generation and analytical guidance, evaluations reveal significant limitations in their reasoning for standard statistical tests. Ecological statistics typically require special consideration due to spatial [...]
