POPULATION BIOLOGY OF THE MOLE CRAB EMERITA BRASILIENSIS (DECAPODA: HIPPIDAE) AT FORA BEACH, BRAZIL

Abstract

and Species of the genus Emerita live in the swash zones of sandy beaches in many parts of the world. The first studies on species of Emerita focused on distribution patterns and their relationship to physical and biological factors (Weymouth and Richardson, 1912; MacGinitie, 1938; Alikunhi, 1944; Efford, 1965; Cubit, 1969; Trueman, 1971). Efford (1967) observed that neoteny is common in males of this genus, and also noted that males are generally smaller than females. Subse- quent studies dealt with the reproductive strategy and population structure of some spe- cies in order to explain the absence of males above a certain length (Barnes and Wenner, 1968; Wenner, 1972; Diaz, 1980; Subramon- ian, 1977, 1979, 1981; Sastre, 1991). Investigations of aspects of population and reproductive biology of Ernerita brasiliensis (Smith) were carried out in southern Brazil by Gianuca (1983, 1985). Larval abundance and distribution were studied by Veloso and Calazans (1985) and Veloso and Valentim (1993) in the same region. Veloso et al.
