Autores: Oliveira,Renildo Ribeiro de; Souza,Issakar Lima; Venere,Paulo Cesar.
The neotropical freshwater systems have a high number of catfish species (Siluriformes), and many of those are denominated "cascudos" in Brazil. Cytogenetic data about three "cascudos" species fished in the rio Araguaia are described in the present study. The Pterygoplichthys joselimaianus showed 2n=52, with 28 metacentrics (M) chromosomes, 16 submetacentrics (SM) and 8 subtelocentrics/acrocentrics (ST/A) in both sexes. Hemiancistrus spinosissimus showed 2n=52, with karyotype formulae 26M+22SM+4ST, in both sexes. Hemiancistrusspilomma also showed 2n=52, but in this species a ZZ/ZW sex chromosome system (25M+21SM+6ST in females and 24M+22SM+6ST in males) was observed. The cells from H. spinosissimus and P. joselimaianus showed one chromosome pair bearing...

Relationships between water transparency and abundance of Cynodontidae species in the Bananal floodplain, Mato Grosso, Brazil
Provedor de dados: 83
Autores: Melo,Cesar Enrique de; Lima,Jane Dilvana; Silva,Eliete Francisca da.
The Cerrado in the Central Brazil is currently one of the most threatened ecosystems in the world. As a result, the aquatic habitats in this biome also undergo great impacts. Alterations related to land-use change increase sediment loadings in rivers, streams and lakes, resulting in sedimentation and decrease in water transparency. Water transparency determines underwater visibility conditions, and as a consequence fish assemblages respond to spatial and temporal changes in this variable. This work aimed to examine the influence of transparency on the abundance and distribution of Cynodontidae species, a visually oriented predatory fish group. Fish sampling was conducted in 15 sites located between Mortes and Araguaia rivers in the Bananal floodplain, Mato...

Feeding of juvenile pirarucu (Arapaima gigas, Arapaimidae) in their natural environment, lago Quatro Bocas, Araguaiana-MT, Brazil
Provedor de dados: 83
Autores: Oliveira,Valdézio de; Poleto,Stephania Luz; Venere,Paulo Cesar.
The stomach content of samples of juvenile Arapaima gigas was analized to obtain information about feeding in natural environments. This species occurs in the Amazonian basin, predominantly in floodplain environment. This is the case of the valley of the middle rio Araguaia, where the lago Quatro Bocas is situated. Juveniles A. gigas prefered insects, microcrustaceans and gastropods, most of autochthonous origin. All the stomachs examined contained at least one food item.
