Spatial distribution of fiddler crabs (genus Uca) in atropical mangrove of nort...
Bezerra, Luis Ernesto Arruda; Dias, Carolina Braga; Santana, Givanildo Ximenes; Matthews-Cascon, HelenaThe influence of abiotic factors on the spatial distribution of the fiddler crabs Uca leptodactyla, U. maracoani,U. rapax and U. thayeri was studied in a tropical mangrove of northeast Brazil. Eight transects were delimited in a mangrovearea of the Pacoti River. On each transect, three 0.25 m2squares were sampled during spring low tide periods from September2003 to August 2004. The sediment of the squares at ea...

Genetic variability of wild and captivity populations of Colossoma macropomum (...
Santos, Carlos Henrique dos Anjos dos; Leitão, Marco Aurélio de Brito; Sousa, Carolina Fernandes Silva de; Santana, Givanildo XimenesTambaqui (Colossoma macropomum) is among the most important fish species of the Amazon and one of the most cultivated in Brazil. In the present work we have evaluated the genetic variability of wild and captivity populations of C. macropomum. Enzymatic markers were used to estimate the genetic variability of 41 specimens from a wild group; and 30, 33 and 45 from three captivity groups, which came from Pentecost...
