Two subspecies and a hybrid of big sagebrush: Comparison of respiration and growth characteristics
Environmental temperatures and growth and respiratory characteristics of natural populations of two subspecies and a hybrid of sagebrush (Artemisia tridentata) that grow on a single hillside were measured to test a hypothesis that adaptation to microclimate temperature patterns restricts these taxa to their native locations and that plant–endophyte associations are important to temperature adap...
متن کاملNative perennial forb variation between mountain big sagebrush and Wyoming big sagebrush plant communities.
Big sagebrush (Artemisia tridentata Nutt.) occupies large portions of the western United States and provides valuable wildlife habitat. However, information is lacking quantifying differences in native perennial forb characteristics between mountain big sagebrush [A. tridentata spp. vaseyana (Rydb.)

Several range-wide petitions have been filed for listing the sage-grouse under the Endangered Species Act. The black-tailed prairie dog, often associated with sagebrush-grass types, and the sagebrush...
متن کاملDifferences in Drought Adaptation between Subspecies of Sagebrush (artemisia Tridentata)
Three subspecies of Artemisia tridentata occupy distinct habitats in the Great Basin of North America: ssp. wyomingensis in low, arid elevations; ssp. vaseyana in high, mesic elevations; and ssp. tridentata in intermediate zones. We evaluated differences in the drought experienced and drought tolerance among the subspecies. Drought tolerance was measured by two traits: the xylem pressure (Cx) c...
متن کاملComposite Shrubs
21 Chapter The sunflower family (Compositae or Asteraceae) is the largest family of flowering plants. Its many species occur around the world as annual and perennial herbs and as shrubs and trees (Chrysothamnus), and matchbrush (Gutierrezia)—make plants of this family among the most common and important plants of the Intermountain area (McArthur and others 1979a; table 1). Shrubs of these gener...
