Comparison of moss microarthropod community structure from fragmented landscapes subjected to experimental heating. Dissimilarity with respect to species richness, total abundance (log-transformed) and evenness was used in a principal components analysis. Variables were normalized to provide equal weighting in the analyses. Euclidean distance was used. Large grey circles represent clusters. The inset on the bottom right shows original variable vectors, with direction of change indicated by the line; the length of the line represents the variable's relative contribution to the construction of the principal components axes.
