The use of an integrative approach to improve accuracy of species identification and detection of new species in studies of stream fish diversity
(2021-04-01)
In this study, we made an inventory of the stream and headwater ichthyofauna of the left bank of the Itaipu Dam Reservoir, located in the lower part of the Upper Paraná River basin, using an integrative approach of molecular ...
A comparative study of fish species identification by gel isoelectrofocusing, two-dimensional gel electrophoresis, and capillary zone electrophoresis
(1999)
A comparative study of fish species identification was accomplished using three different electrophoretic techniques. Sarcoplasmic proteins were extracted from three related fish species and subjected to gel isoelectrofocusing ...
