The present work aims to study the size vs. weight relationship and condition factor of a commercially important crab, Callinectes danae, from an estuarine complex located at Pernambuco State, Northeastern Brazil. After sampled, specimens were measured on their carapace width (CW; mm) weighted wet (WW; g). A total 1,635individuals C. danae analyzed, being 881 males (53.8%) 754 females (46.2%). Males significantly larger heavier than (p < 0.05), expected pattern many crabs. WW CW, described...
The condition factor is a parameter which acts as general indicator of the "well-being" species, and it can be obtained through analysis width vs. weight relationships. present work aims to investigate size relationship crab Goniopsis cruentata (Latreille, 1803). study area was Mundaú/Manguaba estuarine complex, Maceió, state Alagoas, Northeast Brazil. Samplings were monthly accomplished from August 2007 July 2008. A total 626 individuals analyzed, being 309 males 317 females. Males larger...
Los cangrejos Brachyura son especies iteróparas, que presentan alta diversificación en los patrones de reproducción, pueden haber evolucionado como una respuesta específica la especie a las condiciones ambientales. Las tropicales frecuentemente reproducción todo el año debido estables del medio. El cangrejo Goniopsis cruentata es ampliamente distribuida largo Atlántico occidental, y habita prácticamente cada micro-hábitat ecosistema manglar. objetivo presente estudio fue evaluar periodo G....
The knowledge of reproductive traits is essential to the comprehension evolution life history and population dynamics a species. Here, we evaluate morphological maturity, relative growth, fecundity, relationship between size brood loss, seasonal variation in crab Goniopsis cruentata . Crabs were collected during period one year tropical mangrove, Northeast Brazil. Males matured at smaller sizes than females. Compared other studies, this result indicates that there appears be no pattern...
We studied two key traits in the life of organisms, body size and sexual maturity, a population attribute, density, crab Goniopsis cruentata . Also, we evaluated role environmental factors on density. caught crabs mangrove sites that are under different influence tidal fluctuation, obtained pH salinity soil from each site as well rainfall data for period study. Both maturity differed between sites, which individuals small-bodied matured at smaller sizes than their counterparts large-bodied...
Male genitalia present an extraordinary pattern of rapid divergence in animals with internal fertilization, which is usually attributed to sexual selection. However, the effect ecological factors on could also be important, especially so nonretractable because their stronger interaction surrounding environment comparison retractable genitalia. Here, we examine potential a pervasive factor (predation) influence length and allometry male guppies. We sampled guppies from pairs low-predation...
The marine crab Plagusia depressa, despite its broad geographic range, is not well known. Here, we attempt to fill this gap by studying several aspects of biology. We sampled P. depressa in the reefs Coruripe, Brazil and investigated sex ratio, body size, maturity, allometric growth gonopod males abdomen females, reproductive effort, breeding season influence environmental variables. found that 1) overall, does deviate from 1:1; 2) females (33.71±10.62 mm) are larger than (30.45±9.94 mm;...
