Food Subsidies Reduce Livestock Depredations by a Recovering Carnivore

Animal Conservation, EarlyView.
Diversionary feeding—providing food caches to divert predators away from preying on livestock—is a strategy to reduce depredations by Mexican gray wolves but has not been evaluated for its effectiveness. We used data from the Mexican wolf recovery program from 2014‐2021 to evaluate whether diversionary feeding reduced livestock depredations by wolf ...

Exploring management options for moose at their southern range limits considering growing disease risk

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Simulation models for moose in New York including hypothetical disease and harvest scenarios help explore management options under uncertainty. While the population currently appears to be stable, increases in parasite‐induced disease attributed to shared space‐use with white‐tailed deer could lead to declines in this marginal moose population ...
