Última Biological associations of color variation in the Indo-Pacific swimming crab Charybdis hellerii Anais da ABC (AABC) WATANABE,TIMOTEO T.; ZARA,FERNANDO J.; HATTORI,GUSTAVO Y.; TURRA,ALEXANDER; SANT'ANNA,BRUNO S.. A marine biological invasion is a natural process accelerated by human activities, and the crab Charybdis hellerii is an example of a globally widespread invasive species. This study evaluated color variation in C. hellerii and its relationship to the sex, size and sexual maturity of these crabs, and compared the efficiency of a freeware digital image-editing program with a commercially available program. The color of the individuals was analyzed using standardized digital images. The color pattern varied significantly with size; smaller and immature individuals were darker than larger and mature ones. The female abdomen changed in morphology and color with sexual maturity, becoming wider and orange-colored. There was no statistical difference in the color...

A.. The mangrove crab Ucides cordatus is one of the most exploited crustaceans in Brazil. The present study investigated the breeding season of this species and the period of the “andada” phenomenon, when the crabs are active outside their burrows and perform agonistic behaviors. Furthermore related them to environmental factors, in a mangrove on the coast of Brazil, with inferences about management of this crab. The crabs reproduced from October through February. The “andada” occurred from November through February, with typical characteristics in the first two months, during the full and new moon periods, and was influenced positively by the air and soil temperature, luminosity, and tidal amplitude, and negatively by salinity. Based on the results of the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Brachyura; Crab; Mangrove; Management; Reproduction.
