Abundance and occupancy trends of sooty grouse in western Oregon: determining best modeling practices by comparing observed and simulated data

Wildlife Biology, Volume 2026, Issue 4, July 2026.
Sooty grouse Dendragapus fuliginosus are large game birds that occupy montane forests in the Pacific Northwest, USA. These forests have been altered by human activities, which have been shown to have both positive and negative impacts on local populations.

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, Volume 8, Issue 7, July 2026.
We evaluated the impacts of grazing, climatic variability, and vegetation productivity on the population dynamics of a northern Great Plains greater sage‐grouse population. We found winter temperature influenced annual population growth rates, but did not detect influences of drought, breeding season weather, vegetation productivity or short‐term ...

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.

Vitals rates and seasonal movements of two isolated greater sage-grouse populations in Utah's West Desert

Human-Wildlife Interactions, 2017
Declines in greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) populations in Utah over the last century parallel range-wide trends.

Leveraging Next‐Generation Tools for Genetic Assessment and Demographic Monitoring in Threatened and Elusive Humboldt Martens

Evolutionary Applications, Volume 19, Issue 7, July 2026.
ABSTRACT Conservation assessments of imperiled species require information on population structure, abundance, and connectivity which benefit from integrated demographic and genetic data. Humboldt martens (Martes caurina humboldtensis) are a federally threatened subspecies of Pacific marten (Martes caurina) whose conservation has been hindered by ...

Are Sage‐Grouse Fine‐Scale Specialists or Shrub‐Steppe Generalists?

Journal of Wildlife Management, 2020
Sage‐grouse (Centrocercus spp.) are influencing rapidly evolving land management policy in the western United States. Management objectives for fine‐scale vegetation characteristics (e.g., grass height >18 cm) have been adopted by land management ...

The United States Magnetotelluric Array and the National Impedance Map

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract The United States Magnetotelluric Array (USMTArray) data set, collected in the years 2006–2024, consists of more than 1,700 long‐period magnetotelluric stations covering the entirety of the contiguous United States on a quasi‐regular 70 km grid.

Postfire growth of seeded and planted big sagebrush—strategic designs for restoring greater sage‐grouse nesting habitat

Restoration Ecology, 2020
Wildfires change plant community structure and impact wildlife habitat and population dynamics. Recent wildfire‐induced losses of big sagebrush (Artemisia tridentata) in North American shrublands are outpacing natural recovery and leading to substantial ...

Microhabitat Selection by Greater Sage-Grouse Hens During Brood Rearing

Human-Wildlife Interactions, 2017
Greater sage-grouse (Centrocercus urophasianus) populations have declined throughout the western United States over the past century. Loss of large stands of sagebrush is a major factor leading to the decline of sage-grouse populations.
