Abstract
Pattern in a community dominated by Zerna erecta is examined by means of block size analysis of variance. Three scales of pattern are described. The primary pattern is due to the size of individual plants, or in the case of Z. erecta that of the clump. Two further scales common to tne 4 species studied were found at Ns 16 (80 cm) and Ns 64 (320 cm). The use of correlation coefficients in pattern analysis is discussed and results presented which indicate that the larger scales of pattern are due to competition between Z. erecta and the other species. Further observations support the interpretation that the pattern in the community is due to a "fairy ring" type of morphological pattern in Z. erecta, which imposes an inverse pattern on the otner species present.This publication has 16 references indexed in Scilit:
