Density dependence of songbird demographics in grazed sagebrush steppe. [PDF]

open access: yesPLoS ONE, 2023
Sagebrush steppe is one of the most threatened ecosystems in North America. Adult density of songbirds within sagebrush steppe is a metric used to evaluate conservation actions.

Long-term bat abundance in sagebrush steppe [PDF]

open access: yesScientific Reports, 2018
Bats of western North America face many threats, but little is known about current population changes in these mammals. We compiled 283 surveys from 49 hibernacula over 32 years to investigate population changes of Townsend’s big-eared bats (Corynorhinus

Epigaeic spider response to sagebrush steppe restoration treatments

open access: yesEcosphere, 2022
Epigaeic (ground‐active) spiders are dominant predators of arthropods and are important prey for vertebrates in sagebrush steppe systems. As part of the Sagebrush Steppe Treatment Evaluation Project (SageSTEP), the response of epigaeic spiders to ...

Ecosystem functional response across precipitation extremes in a sagebrush steppe [PDF]

open access: yesPeerJ, 2018
Background Precipitation is predicted to become more variable in the western United States, meaning years of above and below average precipitation will become more common.

Response of Sagebrush Steppe Grass Species to AMF Inoculum Sources and Biochar [PDF]

open access: yesMicroorganisms, 2023
The sagebrush steppe has presented increasing levels of degradation. The addition of arbuscular mycorrhizal fungi (AMF) and biochar have been suggested to restore ecosystems. However, little is known about their effects on sagebrush steppe plants.

Post-Fire Vegetation Response in a Repeatedly Burned Low-Elevation Sagebrush Steppe Protected Area Provides Insights About Resilience and Invasion Resistance

open access: yesFrontiers in Ecology and Evolution, 2020
Sagebrush steppe ecosystems are threatened by human land-use legacies, biological invasions, and altered fire and climate dynamics. Steppe protected areas are therefore of heightened conservation importance but are few and vulnerable to the same impacts ...

Shallow snowpack inhibits soil respiration in sagebrush steppe through multiple biotic and abiotic mechanisms

open access: yesEcosphere, 2016
In sagebrush steppe, snowpack may govern soil respiration through its effect on multiple abiotic and biotic factors. Across the Intermountain West of the United States, snowpack has been declining for decades and is projected to decline further over the ...

Resilience to fire and resistance to annual grass invasion in sagebrush ecosystems of US National Parks

open access: yesGlobal Ecology and Conservation, 2021
Western North American sagebrush shrublands and steppe face accelerating risks from fire-driven feedback loops that transition these ecosystems into self-reinforcing states dominated by invasive annual grasses.

Grazing effects on shrub-induced resource islands and herbaceous vegetation heterogeneity in sagebrush-steppe communities

open access: yesGlobal Ecology and Conservation, 2022
Spatial heterogeneity in plant communities promotes coexistence and diversity by providing a variety of niches for different species. In shrub-steppe communities, shrubs create distinct microsites under their canopies (canopy microsites) compared to ...

Post-fire vegetation dynamics of a sagebrush steppe community change significantly over time

open access: yesCalifornia Agriculture, 2015
Sagebrush steppe ecosystems of the Intermountain West have experienced a decline over the past 150 years due to changing fire regimes, invasive species and conifer encroachment.
