Última Morphometrics and cytogenetics of Gracilinanus Agilis and Cryptonanus spp. (Didelphimorphia: Didelphidae) from central and northeastern Brazil Mastozool. neotrop. Garcia,João P.; Oliveira,João A.; Corrêa,Margaret M. O.; Pessôa,Leila M.. Species of the didelphid genera Gracilinanus and Cryptonanus are morphologically and cytogenetically very similar. Several qualitative characters, some of which exhibit intraspecific polymorphisms, have been used to distinguish these genera, but more data are needed to characterize them better. Samples of G. agilis and Cryptonanus spp. from nine localities in central and northeastern Brazil were analyzed. Multivariate analyses of craniodental measurements and descriptive statistics of external body measurements indicate that G. agilis is conspicuously larger than Cryptonanus spp., and that general size is the main factor distinguishing these forms. Size differences can be combined with qualitative characters making the differentiation between G. agilis and...

Souza,Ana L. G.; Corrêa,Margaret M. O.; Pessôa,Leila M.. The karyotype of Dasyprocta azarae has not been described previously. In this article we describe the karyotype of D. azarae from Northern Pantanal, Mato Grosso, Central Brazil. D. azarae has a diploid number 2n=64 and a number of autosomal arms NA=122. The 2n and NA are the same as those reported for other Brazilian species of Dasyprocta, but differ in chromosome morphology. Differences in the sex chromosomes were also found. The Y chromosome is acrocentric whereas in other Dasyprocta species is metacentric or submetacentric. The C-banding pattern coincides with that described for other species, except for pair six, having two bands of heterochromatin. The NOR patterns revealed intraindividual variation, with 1 to 6 NOR chromosomes. In the other species... Tipo: Info:eu-repo/semantics/article Palavras-chave: C-banding; Conventional staining; NOR.
