Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument La Ecología de Borrego Cimarron de las Montañas Rocosas Reintroducido en el Monumento Nacional de Dinosaurio

Wildlife Monographs, Volume 223, Issue 1, August 2026.
We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...

Climatic niche position predicts population dynamics in Mediterranean shrubs after drought

Journal of Ecology, Volume 114, Issue 8, August 2026.
Climatic conditions closer to the species' climatic niche centroid generally resulted in higher population growth in two Mediterranean shrubs, but demographic responses differed between species and were further influenced by drought‐induced vegetation die‐off.

RAPID: Real‐time animal pattern re‐identification on edge devices, an open‐source tool for field deployment

Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2379-2394, August 2026.
Abstract Automatic re‐identification of animals has significant potential to address pressing ecological and conservation challenges through improved population monitoring, individual health assessment and detailed behavioural analyses. Although numerous computer‐vision‐based solutions have been proposed and many achieve high accuracy, most remain ...

Overlap of nonbreeding wandering albatrosses with fisheries and implications for colony‐specific population trajectories at South Georgia

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high.

Translocation effects on regional and local population viability and connectivity

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Translocations and reintroductions aim to improve the viability of isolated populations and promote connectivity for large carnivores. However, there is no established framework for assessing their success. We used the Eurasian lynx (Lynx lynx) in western and central Europe to assess the impact of translocations on the viability of six ...

High and dry: Environmental conditions drive opportunities for disease transmission in desert bighorn sheep

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
By using probabilistic models to predict contacts as a function of spatially and temporally varying environmental conditions, we show that population‐level conditions at the time of disease introduction can structure opportunities for transmission within each population.
