Soil morphology and organic matter dynamics under cheatgrass and sagebrush-steppe plant communities
Widespread cheatgrass (Bromus tectorum L.) invasion represents a major shift in species dominance that may alter ecosystem processes across much of the western US. To investigate differencesExpand

Variable Impacts of Imazapic Rate on Downy Brome (Bromus tectorum) and Seeded Species in Two Rangeland Communities
Abstract The herbicide imazapic is registered for use on rangelands and provides effective short-term control of certain invasive annual grasses. However, details about optimal application rates forExpand

Contrasting responses of Intermountain West grasses to soil nitrogen
The mechanisms responsible for soil-N-mediated species replacement of native perennial grasses by the invasive annual grasses cheatgrass (Bromus tectorum L.) and medusahead (TaeniatherumExpand

Immobilizing nitrogen to control plant invasion
Increased soil N availability may often facilitate plant invasions. Therefore, lowering N availability might reduce these invasions and favor desired species. Here, we review the potential efficacyExpand

Gas exchange, chlorophyll fluorescence parameters and carbon isotope discrimination of 14 barley genetic lines in response to salinity
Abstract Barley is one of the most salt tolerant crop species, and differences between barley genotypes for salinity tolerance have been previously documented. Greenhouse experiments were conductedExpand

Managing soil nitrogen to restore annual grass-infested plant communities: effective strategy or incomplete framework?
Theoretical and empirical work has established a positive relationship between resource availability and habitat invasibility. For nonnative invasive annual grasses, similar to other invasiveExpand

Seedling Interference and Niche Differentiation Between Crested Wheatgrass and Contrasting Native Great Basin Species
Abstract Interference from crested wheatgrass (Agropyron cristatum [L.] Gaertn.) seedlings is considered a major obstacle to native species establishment in rangeland ecosystems; however, estimatesExpand

Comparison of Herbicides for Reducing Annual Grass Emergence in Two Great Basin Soils
Abstract Reducing seed germination and seedling emergence of downy brome (Bromus tectorum L.) improves the success of revegetating degraded shrubland ecosystems. While pre-emergence herbicides canExpand

A role for assisted evolution in designing native plant materials for domesticated landscapes
Developers of native plant propagation materials for wildland restoration may emphasize naturally occurring genetic patterns or, in contrast, the material's empirical performance in comparative fieldExpand

Nitrogen acquisition by annual and perennial grass seedlings: testing the roles of performance and plasticity to explain plant invasion
Differences in resource acquisition between native and exotic plants is one hypothesis to explain invasive plant success. Mechanisms include greater resource acquisition rates and greater plasticityExpand
