Mapping priority areas to mitigate the risk of electrocution of range‐restricted bird species

open access: yesJournal of Applied Ecology, Volume 62, Issue 10, Page 2787-2799, October 2025.
Our study proposes a framework to identify areas with higher electrocution risk, which can be used even in data‐scarce regions or adapted to a multi‐species assessment context. This approach can support proactive strategies for energy companies with an initial assessment identifying areas to avoid installing new power lines, evaluating sites for ...

The crucial role of meshing in computational fluid dynamics simulations for organic geometries in paleobiology: Describing fluid dynamics performance through best practices

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2170-2194, October 2025.
Abstract Computational fluid dynamics (CFD) has become an essential tool for studying fluid interactions in biological systems. While widely used in engineering, its application in the natural sciences, particularly in paleobiology, remains limited due to the challenges of meshing complex organic geometries.

Assessing spatial variability and efficacy of surrogate species at an ecosystem scale

open access: yesConservation Biology, Volume 39, Issue 5, October 2025.
Abstract Preserving biodiversity is a central goal of conservation, but, in practice, monitoring biodiversity often involves assessing population trends for one or a handful of species that are presumed proxies for biodiversity. Despite the popularity of surrogate species strategies, the links between biodiversity and surrogate species are rarely ...
