Resource allocation effects on the timing of reproduction in an avian habitat specialist

open access: yesEcosphere, 2021
Variation in nutrient allocation can influence the timing of breeding and ultimately reproductive output. Time and space constraints might exist, however, if fewer food resources are available to meet the costs of reproduction early during the ...

The performance of drones and artificial intelligence for monitoring sage‐grouse at leks

open access: yesWildlife Biology, EarlyView.
Accurately monitoring sage‐grouse populations is critical for conservation, yet traditional ground‐based visual surveys face challenges in scalability and consistency, prompting the exploration of innovative drone‐based methodologies enhanced by artificial intelligence.

Delisting the Northern Rocky Mountain gray wolf from the US Endangered Species Act: an assessment of political discourse over 20 years

open access: yesWildlife Biology, EarlyView.
Feared, revered, and politicized, wolves have long captured human imagination, and ignited fierce conservation conflicts. In the United States, the Endangered Species Act protects species at risk of extinction from human impacts. This far‐reaching legislation, which impacts development and state‐level wildlife management, has been fraught with legal ...

Spatiotemporal mapping the usable space of free‐roaming equids across the western United States

open access: yesWildlife Society Bulletin, EarlyView.
Identification of the inter‐decadal (2010‐2011) enhancement‐degradation gradients in the usable space for wild equid Herd Management Areas in the Great Basin, USA. Abstract Management of feral equids in the American West is hindered by the lack of a formal habitat map and monitoring system.

Chronic Wasting Disease management responses in North America: A public policy analysis

open access: yesWildlife Society Bulletin, EarlyView.
In this study we use the Multiple Streams Framework from public policy theory to assess the responses of wildlife management agencies in states and provinces with CWD‐positive cases in the United States and Canada to alleviate public concerns and manage the spread of this disease.

Apex predators exploit advantageous snow conditions across hunting modes

open access: yesJournal of Animal Ecology, EarlyView.
Advantageous snow conditions—in terms of snow depth and density—are among the most important features of the winter landscape for two apex predators, regardless of hunting strategy. In a warming climate, the knock‐on effects of a diminishing snowpack may reduce the hunting success of multiple large carnivore species.
