| 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... |

| 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... |

| Population structure of the porcelain crab Petrolisthes armatus (Gibbes, 1850) from the rocky shore of the Farol isle (25º51'S, 48º32'W) was carried out in the following aspects: annual fluctuation of the density, distribution of the developmental stages and sexes over year round, size composition and recruiting period of juveniles into the population. Monthly collections were made in the three sites of the midlittoral, from November/89 to April/91, with the aid of a trap. The air temperature ranged from 13ºC to 28ºC, that of the surface water from 16ºC lo 29ºC and the salinity of the surface water from 06.7 to 31.5. A total of 5.585 individuals of Petrolisthes armatus was collected, among which, 116 were in the megalopa stage, 1,579 juveniles, 830... |
