Precipitation timing mediates life-stage and population-level associations with climate for an indicator species [PDF]

Scientific Reports
Global climate change is contributing to declines in biodiversity, although changes vary across geographic regions and species. The iconic greater sage-grouse (Centrocercus urophasianus; sage-grouse) is central to conservation within the North American ...

NORMAL HEMATOLOGIC AND BIOCHEMICAL VALUES FOR PRELAYING GREATER SAGE GROUSE (CENTROCERCUS UROPHASIANUS) AND THEIR INFLUENCE ON CHICK SURVIVAL

Journal of Zoo and Wildlife Medicine, 2005
Declines in greater sage grouse (Centrocercus urophasianus) productivity and population numbers throughout their range demand a better understanding of how nutrition influences sage grouse populations. During March and April 1999-2001, blood samples were collected from 158 female (73 adult, 85 yearling), free-ranging, prelaying, greater sage grouse ...

Greater sage‐grouse dynamics are influenced by winter temperature rather than indices of grazing, drought, and breeding season weather in a northern Great Plains population

Conservation Science and Practice
High climatic variability and livestock grazing are ubiquitous across greater sage‐grouse (Centrocercus urophasianis) range and may influence the population dynamics of this imperiled rangeland species.

Songbird population trajectories diverge under simulations of conifer encroachment versus removal in a sagebrush ecosystem. [PDF]

Ecol Appl
Abstract Woody plant encroachment into grasslands and shrublands is a global phenomenon that negatively impacts ecosystem services and wildlife populations. North American sagebrush ecosystems have experienced widespread degradation from encroaching conifers, leading to losses of sagebrush‐obligate wildlife.

Space Use and Movements During Egg Laying Associated With Nest Fate and Female Survival in Eastern Wild Turkeys. [PDF]

Ecol Evol
We assessed behaviors of female wild turkeys during the laying period and evaluated impacts of those behaviors on nest success and female survival. We found that increased movements during laying resulted in a decreased probability of nest success but an increased probability of female survival during incubation.

Liver Metal Concentrations in Greater Sage-grouse (Centrocercus urophasianus) [PDF]

Journal of Wildlife Diseases, 2008
Greater Sage-grouse (Centrocercus urophasianus) are a species of concern due to shrinking populations associated with habitat fragmentation and loss. Baseline health parameters for this species are limited or lacking, especially with regard to tissue metal concentrations.

Acute and lagged fitness consequences for a sagebrush obligate in a post mega‐wildfire landscape

Ecology and Evolution, 2022
Species responses to disturbance influence their extinction risks. Greater sage‐grouse (Centrocercus urophasianus) are bioindicators of sagebrush ecosystem health and the loss of sagebrush (Artemisia spp.) due to wildfire, can cause long‐term declines in

Temporal mismatch in space use by a sagebrush obligate species after large‐scale wildfire

Ecosphere, 2022
The increase in size and frequency of wildfires in sagebrush steppe ecosystems has significant impacts on sagebrush obligate species. We modeled seasonal habitat use by female greater sage‐grouse (Centrocercus urophasianus) in the Trout Creek Mountains ...

Surface-active arthropod community response to juniper removal and its implications for avian conservation in sagebrush ecosystems

Global Ecology and Conservation, 2023
Terrestrial arthropods are a critical component of sagebrush ecosystems and serve as a key food source for higher trophic levels, including many avian species of conservation concern.

Directional acoustic radiation in the strut display of male sage grouse Centrocercus urophasianus [PDF]

Journal of Experimental Biology, 1999
ABSTRACT We present evidence that the acoustic component of the strut display of male sage grouse Centrocercus urophasianus is highly directional and that the nature of this directionality is unique among measured vertebrates. Where vertebrate acoustic signals have been found to be directional, they are most intense anteriorly and are ...
