Functional responses of plants to elevated atmospheric CO2– do photosynthetic and productivity data from FACE experiments support early predictions?
TL;DR: The results from 16 free-air CO2 enrichment (FACE) sites representing four different global vegetation types indicate that only some early predictions of the effects of increasing CO2 concentration (elevated [CO2]) on plant and ecosystem processes are well supported as mentioned in this paper.
Journal ArticleDOI
Elevated CO2 increases productivity and invasive species success in an arid ecosystem.

TL;DR: Using free-air CO2 enrichment (FACE) technology in an intact Mojave Desert ecosystem, it is shown that new shoot production of a dominant perennial shrub is doubled by a 50% increase in atmospheric CO2 concentration in a high rainfall year, but elevated CO 2 does not enhance production in a drought year.

Water relations in grassland and desert ecosystems exposed to elevated atmospheric CO2

TL;DR: Results suggest that the indirect effects of CO2 on plant and soil water relations may contribute substantially to experimentally induced CO2-effects, and also reflect local humidity conditions.
Journal ArticleDOI
Soil water exploitation after fire: competition between Bromus tectorum (cheatgrass) and two native species.
TL;DR: B. tectorum competes with native species for soil water and negatively affects their wate status and productivity, but the competition for water does not affect water use efficiency of the native species.
Journal ArticleDOI
Soil resource heterogeneity in the Mojave Desert
TL;DR: Clearly, soil resources for plants are spatially heterogeneous in this desert ecosystem and differ greatly between adjacent micro- and macrosites in this L. tridentata–A.
