Leaf conductance decreased under free-air CO2 enrichment (FACE) for three perennials in the Nevada desert Leaf conductance decreased under free-air CO2 enrichment (FACE) for three perennials in the Nevada desert
A common response of plants to elevated atmospheric CO2 concentration (CO2) is decreased leaf conductance. Consequently, leaf temperature is predicted to increase under elevated CO2. Diurnal patterns of leaf conductance and temperature were measured for three desert perennials, the C3 shrub Larrea tridentata, C3 tussock grass Achnatherum hymenoides and C4tussock grass Pleuraphis rigida...

Physiological variation among native and exotic winter annuals associated with microphytic soil crusts in the Mojave Desert Physiological variation among native and exotic winter annuals associated with microphytic soil crusts in the Mojave Desert
Microbiotic crusts are important components of many aridland soils. Research on crusts typically focuses on the increase in soil fertility due to N-fixing micro-organisms, the stabilization of soils against water and wind erosion and the impact of disturbance on N-cycling. The effect of microbiotic crusts on the associated plant community has received little attention. We quantified the...

Root growth and function of three Mojave Desert grasses in response to elevated atmospheric CO2 concentration Root growth and function of three Mojave Desert grasses in response to elevated atmospheric CO2 concentration
Root growth and physiological responses to elevated CO2 were investigated for three important Mojave Desert grasses: the C3 perennial Achnatherum hymenoides, the C4 perennial Pleuraphis rigida and the C3 annual Bromus madritensis ssp. rubens. Seeds of each species were grown at ambient (360 μl l−1) or elevated (1000 μl l−1) CO2 in a glasshouse and harvested at three phenological stages...
