Canadian Journal of Zoology, 2021 Measurement of physiological responses can reveal effects of ecological conditions on an animal and correlate with demographic parameters. Ecological conditions for many animal species have deteriorated as a function of invasive plants and habitat ...

Fatal Systemic Haemosporidiosis in a Free-Ranging Greater Sage-Grouse (Centrocercus urophasianus)
Journal of Wildlife Diseases, 2023A wild adult Greater Sage-grouse (Centrocercus urophasianus) from northeastern Oregon, US, was found dead, with multiorgan necrosis and inflammation associated with protozoal schizonts and phanerozoites. Molecular characterization identified these protozoa as Plasmodium homopolare H2 and a novel Leucocytozoon sp. lineage.

Wildlife Biology, 2009 Greater sage-grouse Centrocercus urophasianus populations in North Dakota declined approximately 67% between 1965 and 2003, and the species is listed as a Priority Level 1 Species of Special Concern by the North Dakota Game and Fish Department.

The status of Sage-grouse (Centrocercusurophasianus) is of increasing concern, aspopulations throughout its range havecontracted as a result of habitat loss anddegradation. Historically, Sage-grouse wereclassified into two subspecies: eastern(C. u. urophasianus) and westernSage-grouse (C. u.

Lek behaviour in captive sage grouse Centrocercus urophasianus
Animal Behaviour, 1994Abstract Abstract. Lek display and female choice of males was studied in captive sage grouse. Individual males showed significant repeatability in display frequency between years. Variation in female association with males in artificial arenas was largely attributable to variation in the display frequency of individual males and that of males in ...

Molecular Ecology Notes, 2003
AbstractPrimers for five polymorphic microsatellite loci were developed for Greater Sage‐Grouse (Centrocercus urophasianus) using an enrichment/detection protocol. The high level of polymorphism (nine to 33 alleles) suggests that these loci will be applicable for investigating mating systems and paternity analysis as well as population genetics.

Western North American Naturalist, 2020
We present the first known case of aspergillosis found in a wild, augmented Greater Sage-Grouse (Centrocercus urophasianus) population. This case was not directly associated with the sage-grouse translocations and is the first documented in wild sage-grouse populations since the mid-1900s.

Animal Behaviour, 1994
Abstract Abstract. Sage grouse, Centrocercus urophasianus , in an isolated montane basin near Gunnison, Colorado differ in several morphological and behavioural traits from conspecifics studied in other areas of the species' range. Both sexes in Gunnison are smaller than sage grouse elsewhere, and males possess differences in feather morphology as

A New Cestode, Raillietina centrocerci, from the Sage Grouse Centrocercus urophasianus
Transactions of the American Microscopical Society, 1937In the parasitology collections at the University of Wyoming are two lots of cestodes from the sage grouse. One of these lots was collected by George L. Girard in the region of Daniel, the other by Dr. John W. Scott and Ralph F. Honess in the region of the Sweetwater River, both in Wyoming.
