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... |

Glossophaga soricina soricina (Pallas, 1766) plays an important role in the ecosystems where it is found, taking part in the pollination of hundreds of plant species. Here, we statistically compared 12 external characters of 169 specimens collected in three Brazilian biomes: 82 in the Pantanal (Mato Grosso), 45 in the Atlantic Forest (Ilhéus, Bahia) and 42 in the Caatinga (Chapada Diamantina, Bahia). Each character was analyzed by descriptive and inferential statistics. The t-test didn't detect any differences between males and females of each population. The ANOVA with a posteriori Tukey test showed significant results for all traits (Forearm length, Calcar length, Body length, Tail length, Hindfoot length, Ear length, Tragus length, Thumb length,... |
