Última Genetic variability of the Amazon River prawn Macrobrachium amazonicum (Decapoda, Caridea, Palaemonidae) Naturalis Vergamini, F.G.; Pileggi, L.G.; Mantelatto, F.L.. The freshwater prawn Macrobrachium amazonicum is widely distributed in South America, and occupies habitats with a wide range of salinities. Several investigations have revealed the existence of wide intraspecific variability among different populations, although the understanding of this variability is still fragmentary and incomplete. We compared and characterized inland and coastal populations of M. amazonicum from Brazil, using molecular data (16S and COI mtDNA) to describe the degree of variability, structure, and relationships among them. Genetic divergence rates among populations showed variability at the intraspecific level. All the analyses evidenced significant genetic divergence among populations, structuring them in three groups: I- inland...

Ano: 2011 URL: http://www.repository.naturalis.nl/record/369711 Ecological distribution of the shrimp camarao serrinha Artemesia longinaris (Decapoda, Penaeidae) in Fortaleza bay, Ubatuba, Brazil, in relation to abiotic factors OceanDocs Fransozo, A.; Costa, R.C.; Castilho, A.L.; Mantelatto, F.L.. The spatial and temporal distribution of the shrimp Artemesia longinaris in Fortaleza Bay, northern coast of Sao Paulo State, Brazil, in relation to abiotic factors, was studied. Shrimp samples were obtained on a monthly basis from November 1988 through October 1989 at seven pre-delimited transects on board of a fishing vessel supplied with double otter trawl nets. Depth was recorded at the midpoint of each transect; water and sediment samples were taken to measure salinity, temperature, texture and organic matter content of sediment. The shrimps obtained in the trawls were sorted, identified and 100 g subsample at each transect was separated for measurements (carapace length). A total of 3,083 individuals were obtained. Shrimps were more abundant from... Tipo: Journal Contribution Palavras-chave: Abiotic factors; Ecological distribution; Shrimp fisheries; Fishery surveys; Abundance.
