The phylogeny of howler monkeys (Alouatta, Platyrrhini): Reconstruction by multicolor cross-species chromosome painting
TLDR
The phylogenetic analysis indicated that Alouatta is a monophyletic clade which can be derived from a proposed ancestral Atelinae karyotype of 2n=62 chromosomes by a chromosome fusion, a fission, a Y-autosomal translocation and a pericentric inversion.
Radiation and speciation of spider monkeys, genus Ateles, from the cytogenetic viewpoint
TLDR
The chromosomes of 22 animals of four subspecies of the genus Ateles were compared to clarify the phylogenetic relationships of the species and subspecies and to infer the routes of radiation and speciation of these taxa.
Chromosomal similarities and differences between tamarins, Leontopithecusand Saguinus (Platyrrhini, Primates)
TLDR
The data obtained indicate that the two tamarin genera are closely related chromosomally, suggesting that they probably originated from the same ancestral branch.
Chromosomal characterization of two species of genus Steatogenys (Gymnotiformes: Rhamphichthyoidea: Steatogenini) from the Amazon basin: sex chromosomes and correlations with Gymnotiformes phylogeny
TLDR
The observations suggest that the ZZ/ZW system observed in S. elegans likely evolved through CH addition followed by a paracentric inversion, consistent with the phylogenetic hypothesis that tribe Steatogenini should be positioned within family Ramphychthyidae.
Reciprocal chromosome painting between two South American bats: Carollia brevicauda and Phyllostomus hastatus (Phyllostomidae, Chiroptera)
The Neotropical Phyllostomidae family is the third largest in the order Chiroptera, with 56 genera and 140 species. Most researchers accept this family as monophyletic but its species are
Cytogenetic studies in Eigenmannia virescens (Sternopygidae, Gymnotiformes) and new inferences on the origin of sex chromosomes in the Eigenmannia genus
TLDR
A comparative analysis of the present data and prior reports suggests that the sex chromosomes of Eigenmannia may have arisen independently in the different populations.
Chromosome Evolution in Dendropsophini (Amphibia, Anura, Hylinae)
TLDR
The authors' results reveal significant karyotype diversity among Dendropsophini, with diploid chromosome numbers ranging from 2n = 22 in S. goinorum, 2n= 24 in Lysapsus, Scinax, Xenohyla, and almost all species of Sphaenorhynchus and Pseudis, and adiploid number reduction from 24 to 22 in Scarthyla by a chromosome fusion event.
Chromosomal studies in Callicebus donacophilus pallescens, with classic and molecular cytogenetic approaches: Multicolour FISH using human and Saguinus oedipus painting probes
TLDR
There was evidence that, in spite of the high interspecific variation among Callicebus, most of the chromosomes remained conserved.
Comparative chromosomal study of five taxa of genus Callithrix, group Jacchus (Platyrrhini, primates)
TLDR
The karyotypes of four marmoset species of the Callithrix jacchus group were investigated to clarify the taxonomic relationships of this species group and indicate that, from the chromosomal point stand, the marmosets of this group constitute a homogeneous clade.
Genetic and morphological variability in South American rodent Oecomys (Sigmodontinae, Rodentia): evidence for a complex of species
TLDR
The results suggest that O. paricola may be a complex of species that have been separated for some time, and are in the process of morphological and molecular differentiation as a consequence of reproductive isolation at the geographic and chromosomal levels.
