Replacing natural habitats with artificial structures such as pier-pilings, jetties, and seawalls has important consequences to abundances of biota. It is, however, not often known whether these are direct (the novel habitat alters abundances of some species) or indirect (the novel habitat directly alters some aspect of the behavior or ecology of some(More)
Abundances of organisms generally increase with structural heterogeneity and complexity of habitat. Patterns of distribution of hydroids on the kelp Ecklonia radiata were studied in Australia to examine the generality of this pattern. It was predicted that the cover of hydroids on E. radiata would be greater in the most heterogeneous (e.g., peripheral,(More)
