Patterns of the Non-Indigenous Isopod Cirolana harfordi in Sydney Harbour
Table 2
Analyses of the effects of the densities of Cirolana harfordi on densities per taxa, total abundance and number of taxa of the assemblage in oyster-beds in June and October 2010. PERMANOVA (9999 permutations of residuals under reduced model) of Bray-Curtis similarities for the densities per taxa (forth root transformed) and Euclidean distances for total abundance and number of taxa in oyster-beds, where Location is the comparison among three locations in June and six locations in October 2010 (random) and Patch is the comparison among three patches per location (random, nested in Location), using the densities of C. harfordi as a covariate. Factor Patch was not included in the analysis in October 2010 (see methods). a Terms eliminated to increase the power for factors higher in the table.
