Genetic variation and population structure of two species of neo-tropical mud-mussels (Mytella spp)

M. E. G. C. de Oliveira, Russo, C. A. M., Lazoski, C., Vianna, P. Roberto F., and Solé-Cava, A. M., Genetic variation and population structure of two species of neo-tropical mud-mussels (Mytella spp), vol. 4, pp. 197-202, 2005.

Mytella guyanensis Lamarck (1819) and Mytella charruana d’Orbigny (1846) are widespread euryhaline bivalves that have become commercially important in Brazil. Despite their importance, however, no genetic information that would be useful to orient governmental policies is available for these species. We analyzed, through allozyme electrophoresis, populations of M. guyanensis and M. charruana along 3,500 km of Brazilian coast. Pairwise comparisons among gene frequencies in M.

Temporal genetic differentiation in cultured and natural beds of the brown mussel Perna perna (Mytilidae)

K. T. Appio and Weber, L. I., Temporal genetic differentiation in cultured and natural beds of the brown mussel Perna perna (Mytilidae), vol. 6, pp. 127-136, 2007.

Perna perna is the most important cultivated mussel of Santa Catarina, Brazil, sustaining an important economic input for many local families. Natural stocks of P. perna are depleted by the extraction of adults and seeds for consumption and culture. The aim of the present study was to use the microsatellite locus pms-2 to study the variation of the genetic composition and diversity between natural and cultured stocks in samples of 2001 and 2005 from Penha, Santa Catarina.
