Discussion and Reply Reply: Distribution Map of Caves and Cave Animals in the United States (original) (raw)

Abstract

First, we would first like to thank Professor Curl for his comments and interest in our recent work on the geographic distributions of caves and subterranean fauna in the coterminous United States (Culver et al. 1999). We welcome the opportunity to discuss and clar-ify some of the statements made in our manuscript. Each comment of Professor Curl's is addressed in turn. We wish to emphasize that any statistical analysis presented in the paper was solely exploratory in nature in order to provide some initial confirma-tion for the conclusion of similar spatial distributions for the caves and cave species (Figs. 1 & 2). 1) We did not test whether the relationship between S (number of species) and C (number of caves) was linear for two reasons. a) The emphasis in this paper was on demonstrating graphically that a relationship (linear or otherwise) exists between S and C. That can be seen quite clearly in figure 3, which also shows that for large numbers of caves the relationship is a...
