| Ichthyofauna from 29 tidepools in Jericoacoara National Park (Ceará State, Brazil) was sampled. A total of 733 fishes, comprising 16 species belonging to 12 families, was collected. The three most abundant species were the frillfin goby Bathygobius soporator, the sergeant-majorAbudefduf saxatilis and the molly miller Scartella cristata. An invasive species from the Indo-Pacific, the Muzzled blenny Omobranchus punctatus, was also recorded. The known geographic distribution of the blenny Hypleurochilus fissicornis was extended approximately 2,500 km northward. These findings highlight the lack of knowledge of the rocky intertidal ecosystems along the Brazilian coast, an area that needs more sampling effort and ecological data. |

| 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 of the temporal distribution of the decapod populations from a rocky shore at Farol Isle, Matinhos, State of Paraná, Brazil (25o51'S e48o32'W) was carried out. The rocky shore is 13m wide when the tidal level is zero meter and about 8o inclination. In the supralittoral, the rocky basins is mostly covered by a layer of litter coming from the terrestrial environment. In the midlittoral and upper infralittoral, the rocky slope is overlayed by boulders and pebbles and they constitute a highly complex environment of crevices, holes and concavities; the underlayer pebbles are embedded in sand, gravel and mud. In the infralittoral fringe, macrocospic algae grow as a continuous belt. Eight samples were taken by hand, monthly, from May-90 to April-91: two... |

| Decapod crustaceans from rocky shore at Farol Isle, Matinhos, Paraná, Brazil. II. Spatial distribution of population densities. A study of the spatial distribution of the decapod populations from a rocky shore at Farol Isle, Matinhos, State of Paraná, Brazil (25º51'S, 48º32'W) was canied out. In the supralittoral the rocky surface is covered partially by a layer of litter coming from the terrestrial habitats; in the midlittoral boulders and pebbles cover the rocky basin and in the infralittoral, there is a belt of seaweeds. A total of 8 samples were taken by hand, two from each of the following levels: supralittoral (emersion time 8-12 hours), upper midlittoral (4-8), lower midlittoral (0-4) and limit between midlittoral and infralittoral, monthly, from... |

| Annual fluetuation of densities and population strueture of Armases angustipes (Dana, 1852) from a rocky shore at Farol Island, Matinhos, Paraná, Brazil (25º51'S and 48º32'W) were studied. The population strueture was treated in the following aspects: sexual proportion, dial intensity of activities, size composition and its fluetuation, and general condition of the crabs. The collections were made monthly, from January to December 1991. The samples were obtained handly, in the morning and at night, at the supratidal zone during low tides. There were caught 1,139 crabs, among which 34 were juveniles, 544 males, 555 females and 4 ovigerous females. Population density was highest in April (19.56 ind.m"² ) and in October (23.86 ind.m"² ). The sexual proportion... |

| Recruitment and colonization of colonial ascidians, starting on natural scraped substratum, was observed throughout one year, in quadrats marked on sea- and continental-rock faces in the sublittoral fringe of an exposed beach in the Northeast of Brazil. The species of the Didemnidae, Didemnum duplicatum Monniot, 1983, D. psammathodes Sluiter, 1895, and Polysyncraton amethysteum Van Name, 1902, and an unidentified species of Polycitoridae, Eudistoma sp. 1, were recruited. Presenting continuous recruitment of all species, the density of living and dead recruits and colonies was similar on both faces of the rocks. The highest rainfall during winter, affected significantly the recruits density of D. duplicatum and D. psammathodes. Different permanence periods... |
