Cellular slime molds in Ozark caves.

During the course of visits made to a number of caves in Arkansas, Missouri and Oklahoma, samples of cave "soil" material were collected for the purpose of isolating dictyostelid cellular slime molds. These samples were processed in the laboratory, using standard isolation procedures. While samples from some of the caves were devoid of recoverable dictyostelids, material taken from many of the others yielded a modest variety and abundance of dictyostelid species. In addition to the fairly cosmopolitan species Dictyostelium mucoroides, Polysphondylium pallidum and P. violaceum, four or five other species were recovered, including numerous isolates of D. rosarium from a number of different caves. Based upon these data and an earlier study of West Virginia caves, D. rosarium appears to have a preference or at least a particular tolerance for cave environments. This project was supported in part by the National Science Foundation, University of Arkansas, Shepherd University, and The Nature Conservancy.
