Current methods for determining plant age of shrub species require destructive sampling and annual growth ring analysis on the primary stem. Although individual plant ages can frequently be determined in this manner, the method is time consuming and of ...

Demographic characteristics of 3 Artemisia tridentata Nutt. subspecies [PDF]
Journal of Range Management, 2001 Previous research suggested that woody plant recruitment may occur in pulses in semi-arid areas. The overall objective of this study was to determine if this pulse phenomena was recorded in the demographic structures of big sagebrush (Artemisia tridentata Nutt.) stands in Wyoming.

Natural Regeneration Processes in Big Sagebrush (Artemisia tridentata)
Rangeland Ecology & Management, 2014Big sagebrush, Artemisia tridentata Nuttall (Asteraceae), is the dominant plant species of large portions of semiarid western North America. However, much of historical big sagebrush vegetation has been removed or modified. Thus, regeneration is recognized as an important component for land management. Limited knowledge about key regeneration processes,

Investigation of Artemisia tridentata as a biogeochemical uranium indicator
Journal of Geochemical Exploration, 1985Abstract Hydroponic experiments were conducted with seedlings of Artemisia tridentata subsp. tridentata (big sagebrush) to test the effect of the phosphate speciation of uranium in solution on its uptake by big sagebrush. No single complex could be identified as being preferentially taken up by the plant, but the varying aqueous phosphate ...

SEASONAL PATTERN OF NET PHOTOSYNTHESIS OF ARTEMISIA TRIDENTATA
American Journal of Botany, 1973Gas exchange studies were carried out on Artemisia tridentata during the course of a growing season using microclimatically controlled cuvettes and infrared gas analysis. A definite seasonal pattern of net photosynthesis emerged. This pattern was influenced by the interaction of four major factors: plant water potential, leaf temperature, irradiation ...

DIFFERENCES IN DROUGHT ADAPTATION BETWEEN SUBSPECIES OF SAGEBRUSH (ARTEMISIA TRIDENTATA)
Ecology, 1999Three subspecies of Artemisia tridentataoccupy 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.

Mineral Return via the Litter of Artemisia tridentata
American Midland Naturalist, 1977Artemisia tridentata on the A. tridentata-Agropyron spicatum habitat type (h.t.) annually sheds approximately 117 kg/ha of leaf and inflorescence litter as determined by collecting litter of shrubs enclosed in nylon net cages. Total available amounts of cations (kg/ha) to a depth of 1 m on this h.t. are: Ca, 21,936; Mg, 4450; ?, 127.2; and ?, 3588.

CHROMOSOMAL STUDIES OF SUBGENUS TRIDENTATAE OF ARTEMISIA: EVIDENCE FOR AUTOPOLYPLOIDY
American Journal of Botany, 1981The sagebrushes (subgenus Tridentatae of Artemisia—new combination presented in the text) are western North America's most widespread and populous shrub group. Chromosome counts from 120 populations confirm the base chromosome number at x = 9 with numerous 2n = 2x = 18 diploids and 2n = 4x = 36 tetraploids.

Responses of Grasses Seeded in an Artemisia Tridentata Habitat in Nevada
Ecology, 1966Seventeen grass species and two forbs, planted on a minimal Chestnut soil in northern Nevada, were grown under various degrees of competition in the native shrub, Artemisia tridentata, for 18 years. Grass species included seven native bunchgrasses, six exotic bunchgrasses, one native sodformer, and three exotic sodformers.

Plant Ecology, 2006
For much of the western USA, precipitation occurs in pulses, the nature of which determine soil water potential and plant physiological performance. This research utilized three experiments to examine the sensitivity of photosynthesis and water relations for two widespread Great Basin Desert shrub species, Artemisia tridentata (which has both deep and ...
