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 ...

Spectrophotometry of Artemisia tridentata to Quantitatively Determine Subspecies
Rangeland Ecology & Management, 2018Abstract Ecological restoration is predicated on our abilities to discern plant taxa. Taxonomic identification is a first step in ensuring that plants are appropriately adapted to the site. An example of the need to identify taxonomic differences comes from big sagebrush (Artemisia tridentata).

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 ...

Quantification of Eccentricity in Stems of Artemisia tridentata Nutt.
Western North American Naturalist, 2019Previous research has shown that stems of Artemisia tridentata species exhibit extensive lobe formation. Twenty-two stem samples of Artemisia tridentata Nutt. ssp. wyomingensis (ARTRW) and 24 samples of A. t. ssp. tridentata (ARTRT) were investigated to quantify lobe formation characteristics.

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

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.

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,

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 ...

Microsite and herbaceous vegetation heterogeneity after burning Artemisia tridentata steppe
Oecologia, 2008Woody vegetation can create distinct subcanopy and interspace microsites, which often result in resource islands in subcanopies compared to interspaces. This heterogeneity in soil resources contributes to herbaceous vegetation heterogeneity in plant communities.
