Abstract

Distance based multi-response permutation procedures are discussed in the context of analyzing the spatial relationship of short-grass prairie plant species. Under certain conditions, multiresponse permutation procedures may provide useful information on how the spatial relationship of multi-species populations change over large geographical area. This method is illustrated using mapped data of short-grass prairie plants typical of the eastern plains of Colorado. The use of permutation procedure for randomized block experiments indicated that the dominant species tend to be segregated on the four plots used in this study. The large value associated with the measure of agreement suggested a similar structure of the spatial distribution and association of individual species on the plots. Further analysis revealed that all but one of the dominant species occurred in clusters of varying size and density. The ability to study the spatial relationship among species on independent plots provides a valuable tool in studying the spatial dynamics of diverse populations.
