The reproductive cycle of Callinectes danae Smith, 1869 (Decapoda, Portunidae) in the Ubatuba Region, Brazil
TLDR
The reproductive cycle of this species was studied based on their moult cycle and the development of their gonads, evidenced by the presence of ovigerous females with ovaries in all the development phases. Expand
Population biology of Callinectes ornatus Ordway, 1863 (Decapoda, Portunidae) from Ubatuba (SP), Brazil
Departamento de Zoologia Instituto de Biociencias Centro de Aquicultura - UNESP, C.P. 510, Cep 18.618-000 Botucatu, SP
Population biology of Uca maracoani Latreille 1802-1803 (Crustacea, Brachyura, Ocypodidae) on the south-eastern coast of Brazil
TLDR
The population biology of Uca maracoani was investigated in an estuarine mudflat in the Jabaquara River, Paraty, Brazil, where males predominated during most of the year, except in July and August when the proportion of females was higher. Expand
SPATIAL AND SEASONAL DISTRIBUTIONS OF CALLINECTES DANAE (DECAPODA, PORTUNIDAE) IN UBATUBA BAY, SÃO PAULO, BRAZIL
Abstract The spatial and seasonal distributions of Callinectes danae Smith, 1869, in Ubatuba Bay, São Paulo, Brazil, were investigated as a part of a broad study on the general biology of portunidsExpand
Reproduction and recruitment of the South American red shrimp, Pleoticus muelleri (Crustacea: Solenoceridae), from the southeastern coast of Brazil
TLDR
Investigation of reproduction, recruitment, and size at sexual maturity of the shrimp P. muelleri off the coast of the state of São Paulo, Brazil, suggest that the main reproductive months extend from late spring to early summer, and the hypothesis of the intrusion of the South Atlantic Central Water mass suggests that this species has a continuous reproductive pattern.

Comparative analysis of the relative growth of Uca rapax (Smith) (Crustacea, Ocypodidae) from two mangroves in São Paulo, Brazil
TLDR
A study on the relative growth of two populations of Uca rapax was performed primarily to determine the size at onset sexual maturity, finding positive allometric growth of females abdominal width is likely related to the incubation process, while positively allometry growth of male's cheliped almost certainly relates to reproductive behaviour.

The megalopa and juvenile development of Pachygrapsus transversus (Gibbes‚ 1850)(Decapoda‚ Brachyura) compared with other grapsid crabs
TLDR
A review of the available information indicated that settlement of large megalopae and fast juvenile development, preceding a precocious sexual maturity, are trends in Grapsinae and Plagusiinae. Expand
Ecological aspects of hermit crabs (Crustacea, Anomura, Paguroidea) off the northern coast of São Paulo State, Brazil
TLDR
The results of the grouping analysis for sites and species indicated three distinct groups for sites, and four groups for species, which suggests that the occurrence of these anomurans is associated with the environmental and biotic factors analyzed. Expand
Ecology of the Rock Shrimp Sicyonia dorsalis Kingsley, 1878 (Crustacea: Sicyoniidae) in a Subtropical Region of Brazil
The present study analyzes the abundance and distribution of the rock shrimp Sicyonia dorsalis, in rela- tion to water temperature, salinity, depth, organic matter content, and sediment texture inExpand
REPRODUCTIVE CYCLE AND RECRUITMENT PERIOD OF OCYPODE QUADRATA (DECAPODA, OCYPODIDAE) AT A SANDY BEACH IN SOUTHEASTERN BRAZIL
TLDR
Recruitment of young was highest during summer, but the presence of early and late juvenile specimens throughout the year indicates that continuous recruitment is taking place in the studied population. Expand
