The ordination space into which no plots moved from 2011 to 2012 was also high in several shrub species (e.g., Artemisia tridentata
, Berberis fremontii, Rhus aromatica, and Ericameria nauseosa).
O objetivo deste estudo foi investigar as relacoes entre tamanho de semente e porcentagem de germinacao, taxa de germinacao, variacao da germinacao com o tempo e viabilidade das sementes em "Artemisa" (Artemisia tridentata
Differences in big sagebrush (Artemisia tridentata
) plant stature along soilwater gradients: genetic components.
Characterization of a narrow hybrid zone between two subspecies of big sagebrush (Artemisia tridentata
Recent results suggest that systemic induced resistance in sagebrush (Artemisia tridentata
) may not be possible via vascular connections (Karban et al., 2006; Shiojiri and Karban, 2006).
Associated species were the native plants big sagebrush (Artemisia tridentata
Nutt.) and Sandberg bluegrass (Poa secunda J.
The study area includes croplands, big sagebrush (Artemisia tridentata
Nutt.) communities, stands of mountain mahogany (Cercocarpus ledifolius Nutt.), riparian communities, and extensive stands of western juniper.

(big sagebrush) and the neophytic Agropyron desertorum, were used to determine concentrations of P and N[[O.sub.3].sup.-] for simulations.

, chrysothamnus nauseosus).
The vegetation in the upland area along the west side of the site consists of remnants of native Big Sagebrush (Artemisia tridentata
) and Green Rabbitbrush (Chrysothanmus naseosus), and large amounts of introduced weed species, primarily Bromus spp.
Loss of habitat for ground squirrels in the Basin from historical to current time periods was associated primarily with losses of big sagebrush (Artemisia tridentata
), native grasslands, and interior ponderosa pine (Pinus ponderosa).
Similarly, larger and older individuals of big sagebrush (Artemisia tridentata
) were preferred by domestic sheep during summer and fall grazing trials (Yabann et al., 1987),.
