mutagenic effects of mercury pollution as revealed by micronucleus test on three amazonian fish species.genotoxic effect of mercury pollution over amazonian fish species was evaluated by using the micronucleus test (mnt). distinct mean frequencies of micronuclei (mn) were observed in three trophically distinct characin fish species collected in two riverine environments in the amazon basin: the madeira (polluted area) and the solimões (unpolluted area) rivers. mean frequencies of mn observed in prochilodus nigricans (detritivore), mylossoma duriventris (omnivore), and hoplias malabaricus (piscivor ...200515589237
divergent natural selection with gene flow along major environmental gradients in amazonia: insights from genome scans, population genetics and phylogeography of the characin fish triportheus albus.the unparalleled diversity of tropical ecosystems like the amazon basin has been traditionally explained using spatial models within the context of climatic and geological history. yet, it is adaptive genetic diversity that defines how species evolve and interact within an ecosystem. here, we combine genome scans, population genetics and sequence-based phylogeographic analyses to examine spatial and ecological arrangements of selected and neutrally evolving regions of the genome of an amazonian ...201222512735
