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 ...

Artificial exposure to herbivore‐induced volatile organic compounds reduces herbivory and modulates gene expression in potato plants

Journal of Applied Ecology, Volume 63, Issue 8, August 2026.
These findings provide strong mechanistic evidence for VOCs mediating pest resistance and suggest that exposure to herbivore‐induced, plant‐derived VOCs can enhance pest resistance in potato crops. These results might offer novel information for developing ecologically sustainable plant volatile‐based strategies for boosting protection against pests in

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.

An experimental approach to assess the combined effects of multiple stressors on a large vertebrate species

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.

Constructed value of information with iterative scoring and parametric uncertainty to identify management‐relevant research priorities for a declining raptor species

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation
