| A study of the population of the xanthid crab Pilumnus dasypodus Kingsley, 1879 from rocky shore at the Farol Isle (25º51'S and 48º32'W) was carried out in the following aspects: temporal and spatial distributions of density, annual fluctuation of the sex ratio, size composition of the population and reproductive activities of the species. Monthly, four leveis in relation to emmersion time within intertidal zone were sampled, from May/90 to April/91, but Pilumnus dasypodus was obtained only in the levels 2, 3 and 4. The surface water temperature ranged from 16.0ºC (July/90) to 28.0ºC (February/91). A total of 775 individuais of Pilumnus dasypodus were collected among which, 92 were ovigerous females. The population density ranged from 14.63 ind.m-3... |

| A study about species composition, relative abundance, densities, size composition, reproductive and recruiting periods, sex proportion and species diversity of the decapod populations associated to worm reefs of P. caudata (Kröyer, 1856) was carried out. Monthly, samples of worm reef were obtained from August/1997 to July/1998 from Caiobá Beach, Matinhos (25º51 'S and 48º32'W), Paraná State, southern Brazil. Air temperature oscillated from 14.5ºC (July) to 31.0ºC (February), surface water from 18.0ºC (July) to 28.0ºC (January and February), and the salinity from 22%0 (February) to 34%0 (September). Eigth decapod species were found: Petrolisthes armatus (Gibbes, 1850); Pachygrapsus transversus (Gibbes, 1850); Panopeus americanus Saussure, 1857;... |

| 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... |
