The genetic and morphometric population structures of the semiterrestrial crab Armases angustipes from along the Brazilian coast were examined. The influence of the Central South Equatorial Current on larval dispersal of A. angustipes also was evaluated.

Among coastal crabs of the family Sesarmidae from the western Atlantic, there have been problems of misidentification and controversial reports of distribution, especially due to the morphological similarity and sympatric occurrence of some species. In

The semi terrestrial crabs are important elements of the fauna of coastal regions. The aim of this study was to analyze the population structure of Armases angustipes (Dana, 1852) at estuaries of the Ariquindá River, considered a non impacted area,

In a semiterrestrial and estuarine tropical crab, Armases angustipes Dana (Grapsoidea: Sesarmidae), changes in biomass (measured as dry mass, W; carbon, C; nitrogen, N; and hydrogen, H; per individual) and relative elemental composition (C, N, H,

Ontogeny of osmoregulation and salinity tolerance were investigated throughout the larval development of two congeneric species of sesarmid crab, Armases ricordi (H. Milne Edwards) and A. roberti (H. Milne Edwards), and compared with previous observations

The genetic and morphometric population structures of the semiterrestrial crab Armases angustipes from along the Brazilian coast were examined. The influence of the Central South Equatorial Current on larval dispersal of A. angustipes also was evaluated.
