Classical and molecular cytogenetic characterization of Agonostomus monticola, a primitive species of Mugilidae (Mugiliformes)
(Springer, 2009-01-01)
This study reports the first description of the karyotype of Agonostomus monticola, a species belonging to a genus which is considered to be the most primitive among living mugilid fish. Specimens from Panama and Venezuela ...
Comparative cytogenetics of nine species of Hypoptopomatinae (Teleostei: Siluriformes: Loricariidae): The importance of structural rearrangements in chromosome evolution
(2005-12-01)
Fishes of the subfamily Hypoptopomatinae are very common and found in the lowlands of cis-Andean South America from Venezuela to the north of Argentina. With the main objective of contributing for a better understanding ...

Chromosome polymorphism of heterochromatin and nucleolar regions in two populations of the fish Astyanax bockmanni (Teleostei: Characiformes)
(Soc Brasileira Ictiologia, 2010-10-01)
Karyotype and other chromosomal markers as revealed by C-banding and silver (Ag) impregnation in two Astyanax bockmanni populations (Barra Seca Stream and Campo Novo River) were examined. The diploid chromosome number 2n ...

A karyotype comparison between two species of bordered plant bugs (hemiptera, heteroptera, largidae) by conventional chromosome staining, c-banding and rDNA-FISH
(Zoological Institute, 2017-04)
A cytogenetic characterization, including heterochromatin content, and the analysis of the location of rDNA genes, was performed in Largus fasciatus Blanchard, 1843 and L. Rufipennis Laporte, 1832. Mitotic and meiotic ...
Comparative cytogenetic studies in species of the subfamily Callichthyinae (Teleostei: Siluriformes: Callichthyidae)

Chromosomal evolution of tribe Oryzomyini (Rodentia: Cricetidae: Sigmodontinae)
(2022-01-01)
Oryzomyini is the most diverse tribe of subfamily Sigmodontinae, comprising 30 genera and 147 extant species. Cytogenetic studies on Oryzomyini reflect this diversity, revealing an exceptional range of karyotype variability, ...
