Variation in egg size of the freshwater prawn Macrobrachium amazonicum Decapoda, Palaemonidae. Relative growth, morphological sexual maturity, and size of Macrobrachium amazonicum Heller Crustacea, Decapoda, Palaemonidae in a population with an entirely freshwater life cycle. Ocurrence of male morphotypes of Macrobrachium amazonicum Caridea, Palaemonidae in a population with an entirely freshwater life cycle. Brazilian Journal of Biology 74, S—S The influence of environmental variables in the reproductive performance of Macrobrachium amazonicum Heller, Caridea: Palaemonidae females in a continental population.

As a consequence, life-time reproduction should be enhanced, and the generation turnover is accelerated, which suggests an r-selected life-history pattern Reznick et al. All characteristic reproductive traits of M. Future comparative studies of reproductive and other life-history traits may show further characteristic differences between hydrographically and genetically isolated populations of M.

While vicariant divergence between shrimps from the Pantanal and estuarine populations in Northern and Northeastern Brazil is obvious, the situation is not as clear in the Amazon, Orinoco and other large South American rivers, where geographical and genetic isolation is incomplete. If future studies can show phylogenetic divergence also between distant populations living in the same river system, e.

Regardless of vicariant or parapatric mechanisms, the M. The authors thank Dr. Nakagaki, D.
