“…The reproductive pattern at Perequê-açu beach was classified as Seasonal Continuous (according to PINHEIRO & TERCEIRO, 2000), corroborating the pattern found in the congener A. patagoniensis (ALVES & PEZZUTO, 1998a), in which both species occurred in subtropical climate areas. The reproductive pattern registered in this study had been described to other Brachyura from the north shore of the state of São Paulo: Callinectes danae Smith, 1869; Portunus spinimanus Latreille, 1819; Callinectes ornatus Ordway, 1863 and Arenaeus cribrarius (Lamarck, 1818) (COSTA & NEGREIROS-FRANSOZO, 1998;SANTOS & NEGREIROS-FRANSOZO, 1999;MANTELATTO & FRANSOZO, 1999;PINHEIRO & TERCEIRO, 2000, respectively). Generally, Brachyura crustaceans from temperate areas present seasonal reproduction, which occurs in the hottest seasons of the year (WARNER, 1977;ASAKURA & KIKUCHI, 1984), while crabs from tropical and subtropical regions have a continuous reproduction throughout the year, usually in approximate rates (SASTRY, 1983).…”

The Pinnotheridae family is one of the most diverse and complex groups of brachyuran crabs, many of them symbionts of a wide variety of invertebrates. The present study describes the population dynamics of the pea crab Austinixa aidae (Righi, 1967), a symbiont associated with the burrows of the ghost shrimp Callichirus major (Say, 1818). Individuals (n = 588) were collected bimonthly from May, 2005 to September, 2006 along a sandy beach in the southwestern Atlantic, state of São Paulo, Brazil. Our data indicated that the population demography of A. aidae was characterized by a bimodal size-frequency distribution (between 2.0 and 4.0 mm and between 8.0 and 9.0 mm CW) that remained similar throughout the study period. Sex ratio does not differ significantly from 1:1 (p > 0.05), which confirms the pattern observed in other symbiontic pinnotherids. Density values (1.72 ± 1.34 ind. • ap.-1) are in agreement with those found for other species of the genus. The mean symbiosis incidence (75.6%) was one of the highest among species of the Pinnotheridae family, but it was the lowest among the three studied species of the genus. Recruitment pattern was annual, beginning in May and peaking in July, in both years, after the peak of ovigerous females in the population (from March to May). Our findings describe ecological and biological aspects of A. aidae similar to those of other species of this genus, even from different geographic localities.

“…Mantelatto & Fransozo (1999) also found that C. ornatus was present in high abundance and suggested that this is probably related to this species high fecundity and its multiple annual reproductive cycles. The same appears to be the case for H. pudibundus and L. spinosa, indicating that these regions provide favorable conditions for these species.…”

The objective of the present study was to characterize the composition and abundance of the marine brachyuran crabs in non-consolidated sublittoral sediments in two regions, Ubatuba and Caraguatatuba, on the northern coast of São Paulo State, Brazil. In each region, collections were made monthly at seven depths for two years, July 2001 through to June 2003, from a fishing boat equipped with two double-rig nets. A total of 30,231 crabs were caught (13,305 at Ubatuba and 16,926 at Caraguatatuba), representing nine superfamilies (Dromioidea, Homoloidea, Calappoidea, Leucosioidea, Majoidea, Parthenopoidea, Portunoidea, Xanthoidea and Pinnotheroidea), 16 families, 29 genera and 44 species. Among the total species collected, 31 were common to both regions. Caraguatatuba showed higher species richness (42) and a higher H' diversity index (2.93). For both regions, Callinectes ornatus, Hepatus pudibundus and Libinia spinosa were the most abundant brachyurans. The results indicate that the two regions provide favorable environments for brachyurans, resulting in a locally high biodiversity.Key words: Composition, Biodiversity, Brachyura. ResumoO objetivo do presente estudo foi caracterizar a composição e a abundância dos caranguejos no infralitoral não-consolidado de duas regiões (Ubatuba e Caraguatatuba) do litoral norte paulista, Brasil. Em cada região foram realizadas coletas mensais em sete profundidades, durante o período de dois anos (Julho/ 2001 a Junho/ 2003), utilizando-se um barco de pesca equipado com duas redes do tipo "double-rig". Obteve-se um total de 30.231 caranguejos (13.305 em Ubatuba e 16.926 em Caraguatatuba), abrangendo nove superfamílias (Dromioidea, Homoloidea, Calappoidea, Leucosioidea, Majoidea, Parthenopoidea, Portunoidea, Xanthoidea e Pinnotheroidea), 16 famílias, 29 gêneros e 44 espécies. Do total de espécies coletadas, 31 foram comuns para as duas regiões. Dentre as duas regiões, Caraguatatuba apresentou a maior riqueza de espécies (42)

“…Os estágios de desenvolvimento foram categorizados por sua coloração, forma e tamanho em relação ao hepatopâncreas e preenchimento da cavidade torácica, conforme estabelecido por Mantelatto & Fransozo (1999): foram consideradas adultas as fêmeas que apresentavam gônadas em estágio desenvolvido (DE), intermediário (INT), avançado (AV) e em repouso (RE), enquanto os machos foram considerados adultos quando apresentavam gônadas em estágio desenvolvido (DE) e avançado (AV).…”
