Populations of ants in a Missouri Woodland
Populations of ants were studied in a mixed oak-hickory woods in St. Charles County, Missouri. Forty plots of soil, each measuring a yard square, were dug during the fall, winter, and spring, and records were kept of the species of ants, number of colonies, types of nests and hibernating conditions.
Sixteen species of ants, making up 204 colonies, were found in the plots. The common species wereAphaenogaster rudis (62 colonies),Ponera eorctata pennsylvanica (40 colonies), andAmblypone pallipes (39 colonies). Rare, underground species found by this method includedSysphincta pergandei, Proceratium silaceum, and a new species ofStenamma (S. meridionale).
