- Abstract
Abstract Six hundred and twenty-seven specimens of neotropical fishes belonging to thirteen species/populations from southern field (Paraná, State, Brazil) were karyotypicaly analyzed between 2000 and 2006. The study biogeographic region is characterized as a divisor of waters presenting tributaries and headboards of the hydrographic basins of the rivers Tibagi, Iguaçu, Ivaí, and Paranapanema (Upper Paraná Basin) and Ribeira river (East Basin). Two patterns of karyotypic diversification were verified, being one more conserved in the karyotypic macrostructure and the other more diversified. The understanding at of this variability with views to the citotaxonomy and biological conservation was interpreted at the light of (1) the historical biogeography, (2) of the evolutionary time, and (3) of the biology of the species, indicating the study area as highly relevant for the selection of evolutionary potential.
