| In the Pantanal, the largest continuous floodplain in the world, the diversity and distribution of anuran amphibians vary in and across distinct subregions and distinct habitats occurring along inundation gradients. Permanent and natural aquatic habitats are relatively scarce in the Pantanal, and occurrence of temporary aquatic habitats varies seasonally, depending on rains. We here present results of evaluations of anuran's species richness and abundance in a seasonally flooded area in the northwestern section of the Pantanal (Fazenda Baía de Pedra, Cáceres municipality, state of Mato Grosso, Brazil), comparing values obtained in 10 plots systematically distributed over 5 km² with those obtained in additional aquatic plots in the study area. Data were... |

| The western black tamarin, Saguinus niger, is an endemic Brazilian primate currently classified as Vulnerable by the Brazilian environmental authorities. In this paper, we report two new records from an Amazonia-Cerrado ecotone that extend the range of the species further south to the Brazilian state of Mato Grosso. Additionally, we obtained an ecological niche model (ENM) for S. nigerusing eight climatic variables. The results of the ENM analysis suggest that the species is strongly associated with lowland areas where the temperature does not vary significantly among seasons. We also point out that the Araguaia, Tapirapé, and Comandante Fontoura rivers may act, along with open Cerrado formations and more seasonal climate, as southern barriers. The absence... |

| A recent substantial rearrangement of the 882 described eleutherodactyline frog species has considerably improved the understanding of their systematics. Nevertheless, many taxonomic aspects of the South American eleutherodactyline species remain unknown and require further investigation using morphological, cytogenetic and molecular approaches. In this work, the karyotypes of the Brazilian species Ischnocnema juipoca (Atibaia and Campos do Jordão, SP), Barycholos cf. ternetzi (Uberlândia, MG, and Porto Nacional, TO), and Pristimantis crepitans (Chapada dos Guimarães and São Vicente, MT) were analyzed using Giemsa staining, Ag-NOR labeling, and C-banding techniques. All individuals had a diploid number of 22 chromosomes, but the Fundamental Numbers were... |
