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.

To burn or not to burn: Comparing reintroducing fire with cutting an encroaching conifer for conservation of an imperiled shrub‐steppe

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 ...

The Biogeography of Mammals of Fragmented Sagebrush Steppe Landscapes

, 2006
We sampled small mammals of fragmented sagebrush steppe on the Snake River Plain, Idaho, and compared the effects of habitat isolation on their diversity, abundance, and species composition in 2 landscapes, kipukas, which are patches of sagebrush-steppe ...

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.

The Sagebrush Steppe Treatment Evaluation Project (SageSTEP): a Test of State-and-Transition Theory [PDF]

, 2010
The Sagebrush Steppe Treatment Evaluation Project (SageSTEP) is a comprehensive, integrated, long-term study that evaluates the ecological effects of fire and fire surrogate treatments designed to reduce fuel and to restore sagebrush (Artemisia spp ...

Effects of a decade of grazing exclusion on three Wyoming big sagebrush community types

Global Ecology and Conservation, 2022
Livestock grazing is the most extensive land use in Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis [Beetle & A. Young] S.L. Welsh) steppe and its effects on plant community characteristics have been greatly debated.
