Emissions from the Open Laboratory Combustion of Cheatgrass (Bromus Tectorum)

Atmosphere, 2020
Cheatgrass (Bromus Tectorum) is a highly invasive species in the Great Basin of the Western USA that is increasing the frequency and intensity of wildland fires.

Decadal effects of fuel treatments and annual grass invasion on sagebrush ecosystem carbon stocks

Ecosphere
Fuel treatments are implemented across large spatial scales in sagebrush (Artemisia spp.) ecosystems of the US Intermountain West to limit wildfire risk and spread, but treatment effects on ecosystem carbon storage remain poorly understood.

Eco-evolutionary context modifies a destructive plant invader's response to climate. [PDF]

New Phytol
Abiotic environment–fitness relationships can be shaped by evolutionary, ecological, and eco‐evolutionary contexts. Summary Understanding the relationship between climate and fitness will be important when predicting how plant populations respond to climate change. We conducted a replicated common garden experiment (4 sites × 2 yr) with 96 genotypes (n

Quantifying avian resilience to habitat change to support conservation decision-making. [PDF]

Ecol Appl
Abstract Habitat loss and degradation are two of the main drivers of contemporary avian population declines. Wildlife managers are increasingly advocating for tools that provide decision support to set priorities for restoration or conservation efficiently.

Pre‐fire grazing and herbicide treatments can affect post‐fire vegetation in a Great Basin rangeland

Ecological Solutions and Evidence, 2023
Management of wildfire associated with spread of the highly invasive annual grass Bromus tectorum (cheatgrass) is a critical need in the western U.S. We investigated the utility of coupling common rangeland management strategies pre‐fire to modify post ...

Negative effects of an exotic grass invasion on small-mammal communities. [PDF]

PLoS ONE, 2014
Exotic invasive species can directly and indirectly influence natural ecological communities. Cheatgrass (Bromus tectorum) is non-native to the western United States and has invaded large areas of the Great Basin. Changes to the structure and composition

Plant community trajectories following livestock exclusion for conservation vary and hinge on initial invasion and soil‐biocrust conditions in shrub steppe

Conservation Science and Practice, 2022
Adjustments or complete withdrawal of livestock grazing are among the most common conservation actions in semiarid uplands, but outcomes can vary considerably with ecological context.

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.

Climate-Driven Niche Tracking and Genomic Resilience Shape Future Distribution of a Widespread Agricultural Weed. [PDF]

Mol Ecol
ABSTRACT Understanding how agriculturally important species respond to environmental change is critical for maintaining productivity, mitigating agroecosystem threats and sustaining resilience. While crops have traditionally been the focus in agroecosystems, agricultural weeds are integral components that often face even stronger selective pressures ...

Does post-fire recovery of native grasses across abiotic-stress and invasive-grass gradients match theoretical predictions, in sagebrush steppe?

Global Ecology and Conservation, 2023
Interactions among species can strongly affect how plant communities reassemble after disturbances, and variability among native and invasive species across environmental gradients must be known in order to manage plant-community recovery.
