Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.ABSTRACT Monitoring and understanding the population structure of anadromous fishes is vital to their conservation. The southern distinct population segment of green sturgeon (Acipenser medirostris) is a threatened long‐lived anadromous fish, for which we have insufficient information about fundamental aspects of population structure.

Journal of Animal Ecology, Volume 95, Issue 2, Page 359-376, February 2026.Our study reveals that brook charr adopt distinct ‘warm’ and ‘cool’ behavioural tactics to balance foraging and thermal stress in stratified lakes. By linking fine‐scale thermal movements to morphology, we show how temperature‐driven habitat use promotes individual specialization and potential ecotypic divergence under climate change.

WildWing: An open‐source, autonomous and affordable UAS for animal behaviour video monitoring
Methods in Ecology and Evolution, Volume 17, Issue 2, Page 291-300, February 2026.Abstract Drones have become invaluable tools for studying animal behaviour in the wild, enabling researchers to collect aerial video data of group‐living animals. However, manually piloting drones to track animal groups consistently is challenging due to complex factors such as terrain, vegetation, group spread and movement patterns. The variability in

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 272-290, February 2026.Abstract Conservation of marine ecosystems can be improved through a better understanding of ecosystem functioning, particularly the cryptic underwater behaviours and interactions of marine predators. Image‐based bio‐logging devices (including images, videos and active acoustic) are increasingly used to monitor wildlife movements, foraging behaviours ...
