What Makes Great Basin Sagebrush Ecosystems Invasible by Bromus Tectorum?
Ecosystem susceptibility to invasion by nonnative species is poorly understood, but evidence is increasing that spatial and temporal variability in resources has large-scale effects. We conducted a study in Artemisia tridentata ecosystems at two Great Basin locations examining differences in resource availability and invasibility of Bromus tectorum over elevation gradients and in response to di...
متن کاملA Population of Great Basin Pocket Mice, Perognathus parvus, in the Shrub-Steppe of South-Central Washington
A population of Great Basin pocket mice, Perognathus parvus, was live-trapped in 1967-72 on a 2.7-ha study area in south-central Washington to determine their density, reproductive performance, longevity, movements, and home range, as well as their functional role in northern shrub-steppe habitat. During 41,310 trap-nights we captured 15,386 mice representing seven species: Perognathus parvus, ...
متن کاملGenetic variation and local adaptation at a cheatgrass (Bromus tectorum) invasion edge in western Nevada.
Cheatgrass (Bromus tectorum) is an invasive weed in western North America found primarily growing at elevations less than 2200 m. We asked whether cheatgrass is capable of becoming adapted to a marginal habitat, by investigating a population at a high elevation invasion edge. We used a combination of methods, including reciprocal field transplants, controlled environment studies and molecular a...
متن کاملNative Perennial Grasses Show Evolutionary Response to Bromus tectorum (Cheatgrass) Invasion
Invasive species can change selective pressures on native plants by altering biotic and abiotic conditions in invaded habitats. Although invasions can lead to native species extirpation, they may also induce rapid evolutionary changes in remnant native plants. We investigated whether adult plants of five native perennial grasses exhibited trait shifts consistent with evolution in response to in...
متن کاملCorrection: Relative Abundance of and Composition within Fungal Orders Differ between Cheatgrass (Bromus tectorum) and Sagebrush (Artemisia tridentata)-Associated Soils
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. Sagebrush, a native perennial, hosts arbuscular mycorrhizal fungi (AMF), whereas cheatgrass, a winter annual, is a relatively poor host of AMF. This shift is likely intertwined with d...
