Abstract:The responses of ant communities to structural change (removal of an invasive were studied in a replicated experiment in a Chihuahuan Desert grassland. The results from sampling of ant communities by pit-fall trapping were validated by mapping ant colonies on the experimental plots. Spatial and temporal responses of a dominant species were examined by kriging maps and analysis of variance. The Merical and spatial responses of ants recorded from pit-fall trap data were the same as those recorded from mapping ant nests. The dominant liquid feeding species change and environmental stress. The co-dominant seed-harvesting ant, Pogonomyrmex desertorum Wheeler abundance, exhibited a numerical response to ecosystem change but the nests did not change their spatial distribution. Species richness was also affected by ecosystem change.
