Karyotypic variation in the long-whiskered catfish Pimelodus blochii Valenciennes, 1840 (Siluriformes, Pimelodidae) from the lower Tapajós, Amazonas and Trombetas Rivers


	Variation of 18S rDNA (green signal) and 5S rDNA (red signal) chromosomal sites among Pimelodus blochii populations from Amazon basin. The samples from Amazonas River showed two distinct patterns: one observed in the Almeirim population (A) and other observed in the Santarém population (B).
