抄録 The family Pimelodidae represents a very specious fish group but their phylogenetic
relationships are still poorly known. In the present paper were cyiogenetically analyzed five …

抄録 Karyotypes of five pimelodid fish species analyzed were as follow: Pimelodella
avanhandavae (2n= 46; 20m+ 20sm+ 6st), Heptapterus longicauda (2n= 52; 22m+ 26sm+ …

Four fish species of the family Pimelodidae were analyzed. Bergiaria westermani and two
different Pimelodus species have the same diploid chromosome number (2n-56). Despite …

We analyzed cytogenetically specimens of Pimelodella meeki from Tibagi River at Limoeiro
(LM) and from two tributaries, Couro do Boi (CB) and Gabriel da Cunha (GC) Rivers. All …

Three neotropical species of freshwater fish (Pseudoplatystoma fasciatum, P. tigrinum and
Sorubim lima) of the Amazon region (Brazil) were cytogenetically analysed by means of …

Karyotypes and other chromosomal markers were investigated in three species of the catfish
genus Pimelodus, namely P. fur, P. maculatus and Pimelodus sp., from municipality of Três …

Cytogenetic studies of three species of the Pimelodidae family were carried out. The results
showed a diploid chromosome number of 2n= 46 for Pimelodella sp1, 2n= 52 for …

Two Siluriformes species endemic to the São Francisco River basin were characterized by
conventional and differential cytogenetic analyses involving C-banding, Ag-nucleolar …

Various chromosomal banding techniques were utilized on the catfish, Iheringichthys
labrosus, taken from the Capivara Reservoir. C-banding regions were evidenced in …
