Elevated CO2 increases productivity and invasive species success in an arid ecosystem
Arid ecosystems, which occupy about 20% of the earth's terrestrial surface area, have been predicted to be one of the most responsive ecosystem types to elevated atmospheric CO2 and associated globalExpand
Soil water exploitation after fire: competition between Bromus tectorum (cheatgrass) and two native species
SummaryCauses for the widespread abundance of the alien grass Bromus tectorum (cheatgrass) after fire in semiarid areas of western North America may include: (1) utilization of resources freed by theExpand
Soil resource heterogeneity in the Mojave Desert
Heterogeneity of soil resources was investigated in the Mojave Desert to better understand spatial variability of soil attributes in a Larrea tridentata– Ambrosia dumosa community. Six soil samplesExpand
Water relations in grassland and desert ecosystems exposed to elevated atmospheric CO2
Atmospheric CO2 enrichment may stimulate plant growth directly through (1) enhanced photosynthesis or indirectly, through (2) reduced plant water consumption and hence slower soil moisture depletion,Expand
Coping with herbivory: Photosynthetic capacity and resource allocation in two semiarid Agropyron bunchgrasses
SummaryAgropyron desertorum, a grazing-tolerant bunchgrass introduced to the western U.S. from Eurasia, and Agropyron spicatum, a grazing-sensitive bunchgrass native to North America, were examinedExpand
Hydraulic lift among native plant species in the Mojave Desert
Hydraulic lift was investigated among native plants in the Mojave Desert using in situ thermocouple psychrometers. Night lighting and day shading experiments were used to verify the phenomenon.Expand
A test of compensatory photosynthesis in the field: Implications for herbivory tolerance
SummaryThe occurrence of compensatory photosynthesis was examined in the field for all foliage elements on two Agropyron bunchgrass species that differ in their evolutionary history of grazingExpand
TREE AND SHRUB DYNAMICS IN NORTHWESTERN GREAT BASIN WOODLAND AND SHRUB STEPPE DURING THE LATE-PLEISTOCENE AND HOLOCENE'
During the last 12,000 to 30,000 years, a large proportion of the dominant trees and shrubs in modem assemblages of woodland and shrub steppe vegetation in the northwestern Great Basin have undergoneExpand
Competition and facilitation : Contrasting effects of Artemisia tridentata on desert vs. montane pines
Circumstantial evidence suggests that Artemisia tridentata may out-compete Pinus ponderosa and P. jefferyi for water at ecotones between shrub steppe and montane forest vegetation in the Great Basin.Expand
