Karyotype composition of some rodents and marsupials from Chapada Diamantina (Bahia, Brasil)

Abstract: The Chapada Diamantina (CD) is located in Bahia State, between 11-14° S and 41-43° W, being part of the Serra do Espinhaço. The occurrence of different habitats and transition areas permits an interesting mammal fauna composition, with species from different biomes living in sympatry. Species of Didelphimorphia and Rodentia are important members of mammal communities in almost all different habitats, and morphological and cytogenetic characters are important for a correct identification of most of these specie… Show more

“…Reproduction: three females had youngs attached to the teats, one with 11 and two with nine. Karyotype: The karyotyped individuals showed a 2n = 18, NA = 22 (Figure 5), corresponding to the already described karyotype by Carvalho et al (2002) and Pereira and Geise (2007), comprising three pairs of biarmed and five pairs of acrocentric chromosomes. Variation in the NAs is frequent for the species, as reported by Svartman and Vianna-Morgante (1998), showing a variation from NA = 20 in specimens from state of Goiás (Pereira et al, 2008), NA = 24 in Bolívia (Carvalho et al 2002), NA = 28 also in state of Goiás (Carvalho et al 2002) and NA = 30, registered in state of Espírito Santo (Paresque et al 2004).…”

“…Karyotype: Karyologic analyses of two trapped individuals showed 2n = 62, NA = 86, a chromosome complement already described for this species (Maia and Langguth 1987;Pereira and Geise 2007), and different from those described by Gonçalves et al (2005). The autosomal complement consists of 13 pairs of biarmed and 17 pairs of acrocentric chromosomes, varying from medium to small.…”

“…É considerada endêmica da Mata Atlântica (Fonseca et al 1996), mas ocorre em áreas de transição com o Cerrado em Minas Gerais (Carmignotto 2004) e na Bahia em áreas de Cerrado sensu stricto e Floresta estacional semidecidual (Pereira e Geise 2007). A espécie ocorre preferencialmente em áreas montanas entre 500 a 1500 m .…”
