| RESUMEN La mortalidad por pesca ha sido pocas veces estudiada aislando el efecto causado por las capturas. En este estudio se analizó este aspecto usando como modelo biológico al camarón fantasma Callichirus major (Say, 1818), el cual es colectado intensamente en varias regiones de la costa de Brasil. Para ello, la densidad de las galerías y la demografía poblacional de C. major fue analizada en las playas de Gonzaga e Itararé, dos playas contiguas del Estado de São Paulo, Brasil. La playa de Gonzaga fue considerada como control debido a que desde 1992 una ley municipal impide las capturas de C. major, mientras que Itararé fue considerada como tratamiento ya que en este lugar este camarón es recolectado durante todo el año. Los resultados mostraron que la... |

| ABSTRACT: Spatial distribution and egg production of squat lobsters is examined from specimens deposited in the collection of the Museu de Zoologia of the Universidade de São Paulo (MZUSP), Brazil. A total of 1,346 specimens of squat lobsters were analyzed, out of which 169 were ovigerous females. Ovigerous females contained ten species of Munididae (n = 165) and three of Munidopsidae (n = 4). Eleven of the thirteen studied species were distributed along the Brazilian coast, while two of the remaining species in other marine regions. The analysis of bathymetric distribution revealed the presence of four species on the continental shelf (< 200 m depth: M. spinifrons, M. pusilla, M. irrasa, M. flinti), two on the first layer of the continental slope... |

| Freshwater crabs are an important component of the fauna of limnic environments, and out of the two true freshwater crab families present in the Neotropics, Pseudothelphusidae is the most diverse. Considering the lack of information regarding reproductive features of neotropical freshwater crabs, we studied, for the first time, the fecundity and the presence of juveniles carried by females of two pseudothelphusids from the Amazon region - Kingsleya latifrons (Randall, 1840) and Kingsleya ytupora Magalhães, 1986 - and one from Central America - Potamocarcinus magnus (Rathbun, 1896). The two Kingsleya species produced relatively few (56-114) and large eggs (1.9-3.7 mm), typical for species with an abbreviated or direct development. Recently produced eggs... |
