BACKGROUND Comet assay and micronucleus test have been used increasingly to evaluate the genotoxicity of many metals and their organic compounds in aquatic ecosystems. The use of endemic aquatic organisms as biological sentinels has proved useful in environmental monitoring. In this study, the genetic damage caused by methylmercury (MeHg) in Aequidens tetramerus (commonly called acará-sela) was...

All preserved type specimens and type series of the genus Potemnemus Thomson, 1864 from museum collections have been examined.

The type of P. scabrosus Olivier, 1790 is lost, and the original drawing has been designated as a lecto...

The feeding performance on soft and hard prey of two morphs of the trophically polymorphic Neotropical cichlid fish, Cichlasoma citrinellum, was investigated in the laboratory. The molariform morphs, specialized to feed on hard prey, are able to crack snail shells that are twice as hard as those cracked by the papilliform morphs. During ecological bottlenecks in food resources this ability shou...
