Abstract

*[Ant communities in Vermont & New York woods were sampled in 4 time periods to determine species composition, relative abundances, & nest locations in space. The Vermont community was richer, containing more species & higher nest densities than New York. Both communities followed the geometric distribution of species abundances, suggesting that a single resource was mediating competition. The resource most clearly implicated was suitable nest sites, principally pre-formed plant cavities. Nonrandom species associations, underdispersion in every season, & the occurrence of incipient nests overwintering aboveground, all implicated shortage of such cavities. Microhabitat differences which produce suitable nest sites occur over a very small scale in these communities.]
