Abstract


Patterns of spatio-temporal distribution of Brachyura are determined by the interaction amonglife history traits, inter and intraspecific relationships, as well as by the variation of abiotic factors. This studyaimed to characterize patterns of spatio-temporal distribution of Persephona lichtensteinii, Persephonamediterranea and Persephona punctata in two regions of the northern coast of São Paulo State, southeasternregion of Brazil. Collections were done monthly from July 2001 to June 2003 in Caraguatatuba and Ubatuba,using a shrimp fishery boat equipped with double-rig nets. The patterns of species distribution were tested bymeans of redundancy analysis (RDA) and generalized linear mixed models (GLMM) in relation to therecorded environmental factors (BT: bottom temperature, BS: bottom salinity, OM: organic matter andgranulometry (Phi)). The most influent environmental factor over the species distribution was the Phi, and theascendant order of influence was P. lichtensteinii, P. punctata and P. mediterranea. The greater abundance ofP. mediterranea showed a conservative pattern of distribution for the genus in the sampled region. The greateroccurrence of P. punctata and P. lichtensteinii, in distinct transects than those occupied by P. mediterranea,seems to be a strategy to avoid competition among congeneric species, which is related to the substratumspecificity.
