“…However, in that year, Faggioni et al (2017) described the reproductive biology of an L. bufonius population of this species from a location in the municipality of Porto Murtinho. In the case of the humid Chaco, R. azarai and R. scitula have previously been registered by Narvaes & Rodrigues (2009) and Sugai et al (2014a), respectively, but L. syphax, E. matogrosso and L. mystacinus also had not been registered prior to this region of Mato Grosso do Sul State, according to Souza et al (2017). In addition, two other species, Proceratophrys dibernardoi (Ferreira et al 2016) and Ameerega berohoka (Sant'anna et al 2017), were recently recorded in two sites of Mato Grosso do Sul State.…”

“…In summary, the differences found between the species composition from the humid Chaco and Table 2. Cerrado and other areas with the same formations (Uetanabaro et al 2007, Souza et al 2010, Sugai et al 2014a) must be related to the preferences between the type of environment where the species were found. Considering that this study area is in the Chaco and Cerrado transition zone, the presence of different phytophysiognomies that are connected to each other, such as flat lands and natural springs between limestone, natural and temporary water bodies and swamps or permanent dams, in addition to alluvial forests and the riparian forests of the Perdido River, present a complex and permissible environment for a wide variety of species.…”

Anuran Species Composition From Chaco and Cerrado Areas in Central Brazil

Herein, we present an updated inventory and the variations of frog communities' composition from five areas of humid Chaco and Cerrado in municipality of Porto Murtinho, Mato Grosso do Sul state, Brazil. This municipality is located in an area with three ecoregions: Chaco, Cerrado and Pantanal. Through acoustic and visual nocturnal/diurnal and pitfall evaluations from a period of over five years, we recorded 31 species in the Cerrado and 29 species in the humid Chaco. About 90% of the species were previously registered in the municipality of Porto Murtinho. A non-metric multidimensional analysis based on a presence/absence matrix revealed a separation in our sampling sites and communities with Cerrado and humid Chaco characteristics. This peculiarity in the species composition must be related to the transition zone, with the presence of mixed species characteristics of Cerrado and humid Chaco in both areas in the municipality of Porto Murtinho experiences a high degree of deforestation pressure, which threatens both the Cerrado and humid Chaco vegetation. This highlights the importance of knowledge actions about the richness and composition of species, corroborating ecological tools to support conservation in this region.

True toads of the genus Rhinella are among the most common and diverse group of Neotropical anurans. These toads are widely distributed throughout South America, inhabiting a great diversity of environments and ecoregions. Currently, however, the genus is defined solely on the basis of molecular characters, and it lacks a proper diagnosis. Although some phenetic species groups have traditionally been recognized within Rhinella, the monophyly of some of them have been rejected in previous phylogenetic analyses, and many species remain unassigned to these poorly defined groups. Additionally, the identity and taxonomy of several species are problematic and hinder the specific recognition and description of undescribed taxa. In this work, we first perform phylogenetic analyses of separate mitochondrial and nuclear datasets to test the possible occurrence of hybridization and/or genetic introgression in the genus. The comparative analysis of both datasets revealed unidirectional mitochondrial introgressions of an unknown parental species into R . horribilis ("ghost introgression") and of R . dorbignyi into R . bernardoi; therefore, the mitochondrial and nuclear datasets of these species were considered separately in subsequent analyses. We performed total-evidence phylogenetic analyses that included revised molecular (four mitochondrial and five nuclear genes) and phenotypic (90 characters) datasets for 83 nominal species of Rhinella, plus several undescribed and problematic species and multiple outgroups. Results demonstrate that Rhinella was nonmonophyletic due to the position of R . ceratophrys, which was recovered as the sister taxon of Rhaebo nasicus with strong support. Among our outgroups, the strongly supported Anaxyrus + Incilius is the sister clade of all other species of Rhinella. Once R . ceratophrys is excluded, the genus Rhinella is monophyletic, well supported, and composed of two major clades. One of these is moderately supported and includes species of the former R . spinulosa Group (including R . gallardoi); the monophyletic R . granulosa, R . crucifer, and R . marina Groups; and a clade composed of the mitochondrial sequences of R . horribilis. The other major clade is strongly supported and composed of all the species from the non-monophyletic R . veraguensis and R . margaritifera Groups, the former R . acrolopha Group, and R . sternosignata. Consistent with these results, we define eight species groups of Rhinella that are mostly diagnosed by phenotypic synapomorphies in addition to a combination of morphological character states. Rhinella sternosignata is the only species that remains unassigned to any group. We also synonymize nine species, treat three former subspecies as full species, and suggest that 15 lineages represent putative undescribed species. Lastly, we discuss the apparently frequent occurrence of hybridization, deep mitochondrial divergence, and "ghost introgression"; the incomplete phenotypic evidence (including putative character systems that could be used for future phylogenetic...
