Reversing tree expansion in sagebrush steppe yields population‐level benefit for imperiled grouse

Ecosphere, 2021
Woody plant expansion into shrub and grasslands is a global and vexing ecological problem. In the Great Basin of North America, the expansion of pinyon–juniper (Pinus spp.–Juniperus spp.) woodlands is threatening the sagebrush (Artemisia spp.) biome. The

Effects of habitat and land use on breeding season density of male Asian Houbara Chlamydotis macqueenii [PDF]

, 2016
Landscape-scale habitat and land-use influences on Asian Houbara Chlamydotis macqueenii (IUCN Vulnerable) remain unstudied, while estimating numbers of this cryptic, low-density, over-hunted species is challenging.

Nest-Site Selection by Female Black-Capped Chickadees: Settlement Based on Conspecific Attraction? [PDF]

, 1999
Female Black-capped Chickadees (Poecile atricapillus) solicit extrapair copulations (EPCs) from neighboring high-ranking males, and these EPCs result in extrapair young.

Seasonal movements of greater sage‐grouse populations in Utah: Implications for species conservation

Wildlife Society Bulletin, 2016
Greater sage‐grouse (Centrocercus urophasianus; sage‐grouse) is considered an umbrella species for sagebrush (Artemisia spp.) landscapes in western North America. In 2015, the U.S.

Effects of density on lek-site selection by Black Grouse Tetrao tetrix in the Alps [PDF]

, 2016
Capsule: The Black Grouse is a primarily lekking species, but low population density and lack of suitable habitat can lead to the establishment of non-lekking populations.

Adult sage‐grouse numbers rise following raven removal or an increase in precipitation

Wildlife Society Bulletin, 2017
Weather and lethal control of common ravens (Corvus corax; hereafter, ravens) can affect the nesting success of greater sage‐grouse (Centrocercus urophasianus), but implications of these effects in terms of the subsequent size of the breeding population ...

Efficacy of two Variations on an Aerial Lek-Count Method for Greater Sage-Grouse

Western North American Naturalist, 2009
Greater Sage-Grouse (Centrocercus urophasianus) is a species of concern, and accurate population data are needed to monitor conservation management efforts. Conventional, ground-based lek counts are labor-intensive, expensive, and have several sources of potential error and bias, including the practical limits on number and distribution of leks counted.

Pore evolution in interstellar ice analogues: simulating the effects of temperature increase [PDF]

, 2014
Context. The level of porosity of interstellar ices - largely comprised of amorphous solid water (ASW) - contains clues on the trapping capacity of other volatile species and determines the surface accessibility that is needed for solid state reactions ...

Inter-seasonal movements in tri-state greater sage-grouse: implications for state-centric conservation plans

Human-Wildlife Interactions, 2017
The U.S. Fish and Wildlife Service (USFWS) designated greater sage-grouse (Centrocercus urophasianus) as a candidate species to receive protection under the Endangered Species Act in 2010.
