Taxonomic review of the species of Mugil (Teleostei: Perciformes: Mugilidae) from the Atlantic South Caribbean and South America, with integration of morphological, cytogenetic and molecular data
(Magnolia Press, 2015-02-10)
Analysis of morphological, molecular and cytological data helped to define and more precisely characterize the species of Mugil from the Atlantic coasts of South Caribbean and South America, allowing a correction of prior ...
Spermatogenesis and karyotypes of three species of water striders (Gerridae, Heteroptera).
(2010-10-27)
Although they are of economic importance, there have been few cytogenetic studies of the Gerridae (Heteroptera) in Brazil. We examined spermatogenesis (meiosis and spermiogenesis) and nucleolar behavior in three species ...
Cytogenetic evidence for de novo synthesis of rRNA and involvement of nucleolar material in the organization of cell structures during spermiogenesis of Chariesterus armatus (Heteroptera, Coreidae).
(2010-12-01)
The nucleolar material of Chariesterus armatus was analyzed during spermiogenesis in cell preparations impregnated with silver nitrate. Nucleolar corpuscles were observed in spermatids at the beginning of the process, ...

Molecular cytogenetic evidence of hybridization in the “purple corolla clade of the genus Capsicum ” ( C. eximium × C. cardenasii )
(Taylor & Francis Ltd, 2019-10)
A hybrid individual between two taxa from "the Purple Corolla clade of the genus Capsicum", C. eximium x C. cardenasii (2n = 24) was found during a cytogenetic study of a population belonging to C. cardenasii cytotype 1, ...
Spermatogenesis of riffle bugs, Rhagovelia whitei and Rhagovelia sp (Veliidae), and backswimmers Martarega sp (Notonectidae).
(2012-12-01)
We examined the course of spermatogenesis and the meiotic chromosome complements in aquatic species of true bugs, Heteroptera. The chromosome complement of the Veliidae species was 2n = 39 (38A + X0) and 23 (22A + X0) in ...
