Convergence across biomes to a common rain-use efficiency
It is shown that RUE decreases across biomes as mean annual precipitation increases, and during the driest years at each site, there is convergence to a common maximum RUE (RUEmax) that is typical of arid ecosystems. Expand
Assessing the Response of Terrestrial Ecosystems to Potential Changes in Precipitation
Abstract Changes in Earth's surface temperatures caused by anthropogenic emissions of greenhouse gases are expected to affect global and regional precipitation regimes. Interactions between changingExpand
Resource pulses, species interactions, and diversity maintenance in arid and semi-arid environments
Arid environments are characterized by limited and variable rainfall that supplies resources in pulses. Resource pulsing is a special form of environmental variation, and the general theory ofExpand
The biogeography of prediction error: why does the introduced range of the fire ant over-predict its native range?
It is argued that reciprocal comparisons between predicted native and invaded ranges will facilitate a better understanding of the biogeography of invasive and native species and of the role of SDMs in predicting future distributions. Expand
Drought disturbance from climate change: response of United States forests.
This review summarizes characteristics of drought typical to the major forest regions of the United States, future drought projections, and important features of plant and forest community response to drought, and research needs and strategies for coping with future drought. Expand
Responses of soil respiration to elevated CO2, air warming, and changing soil water availability in a model old-field grassland
Responses of soil respiration to atmospheric and climatic change will have profound impacts on ecosystem and global C cycling in the future. This study was conducted to examine effects on soilExpand
Large-scale changes in climate may have unexpected effects on ecosystems, given the importance of climate as a control over almost all ecosystem attributes and internal feedbacks. Changes in plantExpand
Response of net ecosystem gas exchange to a simulated precipitation pulse in a semi-arid grassland: the role of native versus non-native grasses and soil texture
Results indicate that system CO2 efflux strongly controls whole-ecosystem carbon exchange during precipitation pulses, and understanding the mechanistic relationships between the soil characteristics, plant ecophysiological responses, and canopy structural dynamics will be important for understanding the effects of shifting precipitation and vegetation patterns in semi-arid environments.

Net primary productivity of a CO2-enriched deciduous forest and the implications for carbon storage
A central question concerning the response of terrestrial ecosystems to a changing atmosphere is whether increased uptake of carbon in response to increasing at- mospheric carbon dioxideExpand
Light limitation creates patchy distribution of an invasive grass in eastern deciduous forests
It is concluded that light reduction by the A. triloba canopy was the environmental constraint that prevented establishment of M. vimineum beneath this tree. Expand
