| Abstract Species diversity is regulated by historical, neutral and niche processes, with species tolerance, dispersal and productivity guiding diversity at larger scales, while habitat heterogeneity and biotic interactions acts in smaller scales. In rocky shores, several organisms provide secondary substrates for mobile fauna, with macroalgae being the most abundant and diverse ones. The patchiness promoted by different macroalgae hosts enhances small-scale heterogeneity and may increase and maintain the diversity of the mobile organisms, since there is a close relationship between the associated fauna and its hosts. In this study we selected three morphologically different macroalgae that coexist in the same rocky shore height in the Araçá Bay, an area... |

| A study about composition, relative abundance and densities of peracarid populations associated to worm reefs of P. caudata (Kröyer, 1856) from Caiobá Beach, Matinhos, State of Paraná (25º51'S and 48º 32'W) was carried out. Monthly samples were obtained from August/1997 to July/1998. The density was calculated as the number of individuais per liter of worm reef. Three amphipod and three isopod species were obtained. The total density of the amphipod populations varied from 3.85 ind./l (July) to 70.56 ind./l (December) and that of the isopod from 0.25 ind./l (May) to 11.73 ind./l (March), The annual fluctuation of the amphipod densities was closely related to the weight fluctuation of the associated algae. The most numerous amphipod species was Elasmopus... |
