Rainfall Variability, Carbon Cycling, and Plant Species Diversity in a Mesic Grassland
Ecosystem responses to increased variability in rainfall, a prediction of general circulation models, were assessed in native grassland by reducing storm frequency and increasing rainfall quantityExpand

Convergence across biomes to a common rain-use efficiency
Water availability limits plant growth and production in almost all terrestrial ecosystems. However, biomes differ substantially in sensitivity of aboveground net primary production (ANPP) toExpand

An ecological perspective on extreme climatic events: a synthetic definition and framework to guide future research
Summary 1. Growing recognition of the importance of climate extremes as drivers of contemporary and future ecological dynamics has led to increasing interest in studying these locally and globallyExpand

Consequences of More Extreme Precipitation Regimes for Terrestrial Ecosystems
ABSTRACT Amplification of the hydrological cycle as a consequence of global warming is forecast to lead to more extreme intra-annual precipitation regimes characterized by larger rainfall events andExpand

A framework for assessing ecosystem dynamics in response to chronic resource alterations induced by global change.
In contrast to pulses in resource availability following disturbance events, many of the most pressing global changes, such as elevated atmospheric carbon dioxide concentrations and nitrogenExpand

The ecological role of climate extremes: current understanding and future prospects
Summary 1. Climate extremes, such as severe drought, heat waves and periods of heavy rainfall, can have profound consequences for ecological systems and for human welfare. Global climate changeExpand

Productivity Is a Poor Predictor of Plant Species Richness
Standardized sampling from many sites worldwide was used to address an important ecological problem. For more than 30 years, the relationship between net primary productivity and species richness hasExpand

An integrated conceptual framework for long‐term social–ecological research
The global reach of human activities affects all natural ecosystems, so that the environment is best viewed as a social–ecological system. Consequently, a more integrative approach to environmentalExpand

Does species diversity limit productivity in natural grassland communities?
Theoretical analyses and experimental studies of synthesized assemblages indicate that under particular circumstances species diversity can enhance community productivity through nicheExpand

Dominant species maintain ecosystem function with non‐random species loss
Loss of species caused by widespread stressors, such as drought and fragmentation, is likely to be non-random depending on species abundance in the community. We experimentally reduced the number ofExpand
