A spatially explicit modeling framework to guide management of subsidized avian predator densities

Ecosphere, 2023
Anthropogenic resource subsidization across western ecosystems has contributed to widespread increases in generalist avian predators, including common ravens (Corvus corax; hereafter, raven).

The abundance of Greater Sage-Grouse as a proxy for the abundance of sagebrush-associated songbirds in Wyoming, USA

Avian Conservation and Ecology, 2020
Surrogate-species concepts are prevalent in animal conservation. Such strategies advocate for conservation by proxy, wherein one species is used to represent other taxa to obtain a conservation objective.

Maximizing the detection probabilities of dusky grouse for population monitoring

Wildlife Biology, EarlyView.
Despite its status as a game species in the western USA, rigorous monitoring of dusky grouse Dendragapus obscurus populations is limited. Obtaining an adequate number of observations for effective population monitoring of dusky grouse is challenging due to difficult‐to‐reach montane habitats, cryptic behaviors, and limited personnel, time, and funds at

Diurnal space use and seasonal movement patterns of greater sage‐grouse in Northeastern California

Wildlife Society Bulletin, 2014
Greater sage‐grouse (Centrocercus urophasianus) populations have declined throughout their geographic range, are considered a candidate species under the U.S.

Dusky grouse seasonal resource selection in the Great Basin isolated mountain ranges of Nevada, USA

Wildlife Biology, EarlyView.
Dusky grouse Dendragapus obscurus are a montane forest grouse species with a paucity of information regarding their temporal and spatial resource use during critical times of high mortality and reproductive output. This lack of vital data may leave dusky grouse at risk of sub‐optimal management in many areas of their distribution, especially in the ...

Wyoming Sage-Grouse Working Groups: Lessons Learned

Human-Wildlife Interactions, 2017
The greater sage-grouse (Centrocercus urophasianus) has been the subject of multiple status reviews under the Endangered Species Act (ESA). Wyoming accounts for approximately 38% of the range-wide population.

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

Wildlife 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.

Mapping sage‐grouse fence‐collision risk: Spatially explicit models for targeting conservation implementation

Wildlife Society Bulletin, 2013
Recent research suggested greater sage‐grouse (Centrocercus urophasianus; hereafter, sage‐grouse) fence collision may be widespread, and fence‐marking methods have been developed for reducing prairie‐grouse collision in sagebrush‐steppe habitats. However,

Development of optimized methods for unbiased dusky grouse population monitoring using real and simulated data

Wildlife Biology, EarlyView.
Rigorous state‐wide monitoring programs are lacking for dusky grouse Dendragapus obscurus, a North American species of forest grouse with relatively low detectability that is found in coniferous and mountainous areas in the western United States and Canada.

Impact of sagebrush nutrients and monoterpenes on greater sage-grouse vital rates

Human-Wildlife Interactions, 2017
Greater sage-grouse (Centrocercus urophasianus; sage-grouse) depend on sagebrush (Artemisia spp.) to complete its annual life cycle. The winter diet for sage-grouse consists almost entirely of sagebrush leaves, and individual birds may gain weight while ...
