Moving from the Dilution Effect to Dilution Landscapes: Effects of Natural Vegetation Cover and Fragmentation on Host-parasite Eco-evolutionary Dynamics
Published: 2025-08-20
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
The conversion and fragmentation of natural landscapes are key drivers of biodiversity loss and the erosion of ecosystem services, including disease regulation. Although habitat degradation is linked to higher zoonotic disease risk, the mechanisms by which landscape structure shapes host-parasite eco-evolutionary dynamics remain poorly understood. Here, we combine a spatially explicit [...]
Causal interpretations can be based on mechanistic knowledge
Published: 2025-08-20
Subjects: Ecology and Evolutionary Biology, Life Sciences
1. There exists a long-standing disconnect between statistical and mechanistic approaches to the development of causal understanding. Statistical approaches, which have dominated the literature, have focused on the need to obtain perfectly unbiased estimates of causal effects often using either experimental, quasi-experimental, or other methods. Mechanistic approaches have instead focused on [...]

“But I can’t preregister my research”: Improving the reproducibility and transparency of ecology and conservation with adaptive preregistration for model-based research
Published: 2025-08-19
Subjects: Ecology and Evolutionary Biology, Research Methods in Life Sciences
1. Preregistration is an open-science practice which aims to improve research transparency and mitigate questionable research practices, like cherry-picking results. It helps protect against cognitive biases, like hindsight bias, that can influence how study outcomes are interpreted. There has been little uptake of preregistration in ecology and conservation, arguably because existing [...]
Infection profiles in a wild rat–protozoan network are shaped by host traits and environmental factors
Published: 2025-08-18
Subjects: Ecology and Evolutionary Biology, Life Sciences, Pathogenic Microbiology
Heterogeneity in parasite infection among hosts shapes transmission dynamics and spillover risk to other host species but remains poorly understood in natural systems. We applied network-based stochastic block modeling and machine learning to a uniquely rich dataset to identify and predict protozoan infection profiles in introduced black rats (Rattus rattus) sampled along an environmental [...]
Weather conditions are systematically associated with long-range nonroutine movements in a large scavenger
Published: 2025-08-15
Subjects: Ecology and Evolutionary Biology, Zoology
Movement data are valuable for the conservation of Old World vultures, as these move across large distances and experience a wide range of threats. As vultures rely on soaring flight, the interplay of solar radiation, as well as wind direction and strength, is crucial for both short- and long-range movements. However, no study explored the extent to which weather conditions can predict long-range [...]
The SORTEE Guidelines for Data and Code Quality Control in Ecology and Evolutionary Biology
Published: 2025-08-15
Subjects: Ecology and Evolutionary Biology
Open data and code are crucial to increasing transparency and reproducibility, and in building trust in scientific research. However, despite an increasing number of journals in ecology and evolutionary biology mandating for data and code to be archived alongside published articles, the amount and quality of archived data and code, and subsequent reproducibility of results, has remained [...]
From Shorelines to Social Media: Mixed-Methods Insights into Urban Fishing Practices, Policy Gaps and Culture in the Digital Age
Published: 2025-08-15
Subjects: Ecology and Evolutionary Biology, Environmental Studies, Life Sciences, Social and Behavioral Sciences
Recreational and subsistence fishing are globally significant forms of marine resource use, contributing to food security, cultural identity, and social well-being across diverse coastal communities. Yet these non-commercial sectors are often overlooked in formal fisheries monitoring and governance. In California’s San Francisco Bay Area, non-commercial fishers represent a wide range of [...]
Revisiting evolution at the rear edge
Published: 2025-08-13
Subjects: Ecology and Evolutionary Biology
Rear-edge populations occur at species’ warmer range limits, with many still occupying glacial refugia. They offer valuable insights into evolution under changing climates yet are underused as models. From two decades of research, we identify three equally likely evolutionary patterns in rear edges: high levels of genetic diversity and differentiation, elevated genetic drift, and strong local [...]
Strain-specific thermal acclimation, but little evidence of transgenerational plasticity, in an asexual crustacean
Published: 2025-08-11
Subjects: Ecology and Evolutionary Biology, Life Sciences, Zoology
Transgenerational plasticity has been suggested as a means for species to succeed in rapidly changing environments, such as increased temperature brought on by climate change. However, the evidence for this phenomenon in animals is mixed. The freshwater crustacean Daphnia magna displays transgenerational plasticity in response to environmental cues such as the presence of predators or food, but [...]
Opportunities for Cities to Cultivate Biodiversity
Published: 2025-08-11
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Policy, Environmental Studies, Other Ecology and Evolutionary Biology, Other Plant Sciences, Public Policy, Recreation, Parks and Tourism Administration, Systems Biology, Urban Studies and Planning
Cities pose a major threat to global biodiversity in every sense of the word. Municipal leaders have opportunities to promote biodiversity efforts in their cities. Several studies have shown that managing resources with biodiversity in mind within cities is effective and benefits both human and non-human residents and visitors. Two major opportunities for biodiversity investment in urban areas [...]
Predictive Evolutionary Genomics: Principles, Validation, and Practice
Published: 2025-08-11
Subjects: Agriculture, Biodiversity, Ecology and Evolutionary Biology, Evolution, Genomics, Life Sciences, Plant Sciences, Population Biology
Contemporary evolution occurs on observable timescales, enabling prospective evolutionary forecasting with quantitative frameworks rather than only retrospective inference. We propose a unified probabilistic framework that integrates three approaches linked to detectability windows through time. Trait-based models use multivariate quantitative-genetic equations to project correlated phenotypic [...]
Progress toward sustainable management of marine crustacean fisheries
Published: 2025-08-11
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Sciences, Marine Biology, Natural Resources and Conservation, Natural Resources Management and Policy, Population Biology
Marine crustacean capture fisheries have been contributing increasingly more to global aquatic food production in recent decades, helping secure socioeconomic benefits. In the past decade the landings of marine crustaceans rose by more than 67% while expanding spatially and taxonomically, doubling their contribution to global fisheries landings. Although efforts to improve the data collection [...]
