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

open access: yesEcol 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]

open access: yesEcol 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.

Predator‐specific mortality of sage‐grouse nests based on predator DNA on eggshells [PDF]

open access: yesEcology and Evolution
Greater sage‐grouse (hereafter sage‐grouse; Centrocercus urophasianus) populations have declined across their range. Increased nest predation as a result of anthropogenic land use is one mechanism proposed to explain these declines.

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

open access: yesScientific 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

open access: yesJournal 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 ...

Factors Affecting Greater Sage-Grouse (Centrocercus Urophasianus) Survival and Movement in South-Central Utah

open access: yes, 2011
Greater sage-grouse (Centrocercus urophasianus) adult and juvenile survival have been identified as critical demographic parameters. However, little is known regarding the dynamics of juvenile sage-grouse. From 2008-2010, I used radio-telemetry and 2 transmitter types to monitor 91 juvenile sage-grouse.

Evaluation of population monitoring strategies for greater sage-grouse (Centrocercus urophasianus) in northwestern Colorado [PDF]

open access: yes, 2017
Population monitoring programs are essential for the proper management of wildlife species but, despite recent advances in methodologies, generating accurate and defensible estimates of population size and trend remains a key challenge for wildlife biologists and managers and effective monitoring programs generally require considerable resources ...

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

open access: yesJournal 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.
