Differential Utilization of Allochthonous and Autochthonous Carbon By Aquatic Insects of Two Shrub-Steppe Desert Spring-Streams: A Stable Carbon Isotope Analysis and Critique of the Method
<p>Stable carbon isotope analysis, a technique that measures the ratio of stable carbon-12 to stable carbon-13 in abiotic and biotic components of ecosystems, was used to assess the differential utilization of autochthonous and allochthonous carbon by aquatic insects of two cold desert …

Seasonal dispersal tendencies of sylvan deer mice (peromyscus maniculatus) with montana rangelands
… The rangeland types included a grassland and shrub-steppe habitat. Within the state of Montana, both habitat types commonly contain peridomestic settings due to the widespread influence of the ranching industry. These peridomestic environments are where most reported human cases of Hantavirus …

Vegetation response of a Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis) community to 6 mechanical treatments in Rich County, Utah
In recent years, the importance of sagebrush to shrub-steppe ecosystems and associated plant and animal species has been recognized. The historical removal of herbaceous species by excessive and uncontrolled livestock grazing on many of our sagebrush ecosystems has resulted in a stagnant state …

Seasonal responses of carbon, nitrogen, and phosphorus cycling to woodland reduction and different organic matter additions in the semiarid Great Basin
Abstract:Disturbances that impact microbially-mediated processes of decomposition and mineralization of organic matter carry ecosystem-level consequences because soil microorganisms can immobilize nutrients or render them available for plant uptake. The stochastic nature of resource availability in …
