Relative abundance of and composition within fungal orders differ between cheatgrass (Bromus tectorum) and sagebrush (Artemisia tridentata)-associated soils. [PDF]
PLoS ONE, 2015 Nonnative Bromus tectorum (cheatgrass) is decimating sagebrush steppe, one of the largest ecosystems in the Western United States, and is causing regional-scale shifts in the predominant plant-fungal interactions.

Grazing intensity effects on herbaceous community composition in burned sagebrush steppe
Ecosphere, 2023 There is limited knowledge of grazing impacts on longer term plant community dynamics following fire in sagebrush steppe. This study evaluated vegetation response to different intensities of deferred rotation cattle grazing over 16 years (2007–2022) on ...

Influence of directional side of sagebrush canopies and interspaces on microhabitats
Basic and Applied Ecology, 2023 Shrubs can contribute to spatial heterogeneity in plant communities by creating distinct microsites under their canopies compared to between their canopies (interspaces).

Ecological Solutions and Evidence, 2022 Invasions by exotic annual grasses (EAGs) are replacing native perennials in semiarid areas globally, including the vast sagebrush‐steppe rangelands of western North America.

The Seasonal Water Balance of Western-Juniper-Dominated and Big-Sagebrush-Dominated Watersheds
Hydrology, 2021 The combined impacts of woody plant encroachment and climate variability have the potential to alter the water balance in many sagebrush steppe ecosystems in the Western USA, leading to reduced water availability in these already water-scarce regions ...

Cumulative effects of an herbivorous ecosystem engineer in a heterogeneous landscape
Ecosphere, 2016 Foraging by herbivores alters individual plants and vegetation communities directly, and engineering behaviors such as bioturbation (digging and turning soil) and biodeposition (deposition of feces and urine) can affect soils and physical properties that

Harvester ant seed removal in an invaded sagebrush ecosystem: Implications for restoration
Ecology and Evolution, 2020 A better understanding of seed movement in plant community dynamics is needed, especially in light of disturbance‐driven changes and investments into restoring degraded plant communities.

Ecology and Evolution, 2019 Woody vegetation has increased on rangelands worldwide for the past 100–200 years, often because of reduced fire frequency. However, there is a general aversion to reintroducing fire, and therefore, fire surrogates are often used in its place to reverse ...

Ecosystem resilience is evident 17 years after fire in Wyoming big sagebrush ecosystems
Ecosphere, 2016 Recent policy has focused on prevention of wildfire in the sagebrush steppe in an effort to protect habitat for the greater sage grouse (Centrocercus urophasianus).

Protecting restoration investments from the cheatgrass‐fire cycle in sagebrush steppe
Conservation Science and Practice, 2021 The U.S. federal government has recently committed to the difficult task of slowing and managing the invasive grass‐fire cycle in sagebrush steppe, where property, livelihoods, and entire ecosystems are at risk.
