Population biology of the burrowing crab Neohelice granulata, (Crustacea: Decapoda: Varunidae) from a tropical mangrove in Brazil
Provedor de dados: 103
Autores: Gregati,Rafael A.; Negreiros-Fransozo,Maria L.
The population biology of the burrowing crab Neohelice granulata (Dana, 1851) from a mangrove in Jabaquara Beach, Paraty, state of Rio de Janeiro, Brazil (23º13'04"S and 44º42'47"W), was studied with respect to the following traits: size-frequency distribution, recruitment, reproductive period, fecundity, and sex ratio. Specimens were sampled monthly from April, 2003 to March, 2004, at the river margins during low tide periods. Size, sex, presence of eggs, and stage of the female gonad were recorded. Ovigerous females had their eggs removed and counted. The reproductive period was continuous and the highest frequency of ovigerous females was recorded in the fall and winter. Mature gonads were found throughout the year and recruitment was continuous but...

The megalopa and early juvenile development of Hepatus pudibundus (Crustacea: Brachyura: Aethroidea) reared from neuston samples
Provedor de dados: 104
Autores: Negreiros-Fransozo,Maria L.; Fransozo,Adilson; Hirose,Gustavo L.
Hepatus pudibundus (Herbst, 1785) is a crab commonly found in shallow waters of the Western Atlantic. Its larval and early post-larval morphology have already been described from laboratory hatched material. Around 200 megalopae of H. pudibundus were collected in neuston samples from the Ubatuba region, Brazil, during the summer of 2005-2006 and were successfully reared under laboratory conditions. The size of the megalopae obtained in the neuston was similar to those specimens previously described in the literature, except that the juvenile crab stages reared in the laboratory were slightly larger, probably due to the better feeding conditions in the laboratory. The duration of the juvenile stages was shorter in the present study than in previous attempts...

Ciclo reprodutivo do caranguejo violinista Uca rapax (Smith) (Crustacea, Brachyura, Ocypodidae) habitante de um estuário degradado em Paraty, Rio de Janeiro, Brasil
Provedor de dados: 104
Autores: Castiglioni,Daniela da S.; Negreiros-Fransozo,Maria L.
Este trabalho descreve o ciclo reprodutivo de Uca rapax (Smith, 1870) baseado em observações do seu desenvolvimento gonadal e ciclo de muda em uma área de manguezal degradado em Paraty, Estado do Rio de Janeiro. Os caranguejos foram capturados por duas pessoas mensalmente (julho/2001 a junho/2002) durante 15 minutos por meio da técnica de esforço de captura em período de maré baixa. No laboratório, os caranguejos foram mensurados quanto à largura da carapaça (LC); sendo o sexo, a condição ovígera e o estágio gonadal anotados. Os estágios de desenvolvimento gonadal foram determinados por meio da observação macroscópica das gônadas e os estágios de muda através da observação do grau de enrijecimento do tegumento. Os caranguejos que apresentavam gônadas...
