Are Mojave Desert annual species equal? Resource acquisition and allocation for the invasive grass Bromus madritensis subsp. rubens (Poaceae) and two native species.
Abundance of invasive plants is often attributed to their ability ot outcompete native species. We compared resource acquisition and allocation of the invasive annual grass Bromus madritensis subsp.… Expand

Physiological variation among native and exotic winter annual plants associated with microbiotic 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… Expand

Seed banks in a degraded desert shrubland: Influence of soil surface condition and harvester ant activity on seed abundance
Abstract We compared seed banks between two contrasting anthropogenic surface disturbances (compacted, trenched) and adjacent undisturbed controls to determine whether site condition influences… Expand

Leaf conductance decreased under free-air CO2 enrichment (FACE) for three perennials in the Nevada desert
Summary •  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.… Expand
