studies are needed to understand the consequences of global
climatic change for local community structure and associated
ecosystem processes. We propose to use large open-top
environmental chambers to simultaneously manipulate air and soil
temperatures using a statistically powerful and cost-efficient
response-surface (regression) design at two field sites situated
in northern and southern temperate mixed hardwood forests in
eastern North America (Harvard Forest in Massachusetts, Duke
Forest in North Carolina). The proposed field manipulations will
reveal the effects of temperature increases on the populations,
communities, and associated ecosystem services of assemblages of
ground-foraging ants. Ants are a model taxon for studying
effects of global climatic change
