Provedor de dados: 104
Autores: Santos,Sandro; Rieger,Paulo Juarez; Vieira,Roni Roberto Ramos; Barutot,Roberta Araújo.
The Lagoa do Peixe ("Peixe's Lagoon") is located between Atlantic Ocean and Lagoa dos Patos and is 30 Km long and 0,5-2,0 Km wide (31º13'S, 50º55'W -31º26'S, 51º09'). For one year, the composition and distribution of Crustácea Decapoda were analyzed monthly (from July/1994 to June/1995), in seven subareas (terrestrial border and aquatic area) and physical and chemical parameters (depth, salinity, sediment texture, oxygen in water, organic material of sediment and water temperature) were registered. Decapoda from the families Grapsidae, Ocypodidae, Portunidae (Brachyura), Diogenidae (Anomura) and Penaeidae (Penaeidea) were captured. Chasmagnathus granulata Dana 1851 was found ali months near the canal connecting Atlantic Ocean and Lagoa do Peixe, but inside...

Provedor de dados: 104
Autores: Bueno,Alessandra Angélica de Pádua; Bond-Buckup,Georgina.
The crustaceans of the genus Aegla Leach, 1820, are found in streams, rivers of caves, current rivers and lagoons, from Franca, São Paulo, Brazil (20º60'S, 47º40'W), to Ilha Madre de Dios (5uº01'10"S, 75º18'45"W), Chile in South America. The crabs (Aegla plalensis Schmitt, 1942) were monthly sampled by hand fromjuly 1997 to september 1998 in Arroio do Mineiro, Taquara (29º46'S, 50º53'W), Rio Grande do Sul, Brazil. The sex, the length and width of the carapace were registered. After being collected the animais were returned to the stream. The repro-ductive period, the size at the first maturation and the sex-ratio were identifred. The reproductive period of A. platensis lasts the whole year. The percentage of ovigerous females is higher in july. The size at...

A formação dos oostegitos em Porcellio dilatatus Brandt (Crustácea, Isopoda, Oniscidea) em laboratório
Provedor de dados: 104
Autores: Loyola e Silva,Jayme de; Coraiola,Maria Aparecida Sídor.
Woodlice were reared in laboratory in the environmental climate of the city of Curitiba, Brazil, with the purpose of getting to know the process of formation of oostegites. Two kinds of cultivation were adopted: natural populations to be controlled were kept in small glass aquariums resembling the natural environment; and, new-bom woodlice were raised each one isolated in small plastic receptacles, with a special diet until two years old or over. When adults, after recognizing their sexes, males and females were put together to copulate during one or more days, and some of the females were fertilized. After 30 days, the fertilized females realized ecdise and acquired oostegites. The complete process (copulation, fecundation, incubation and birth) occurred...
