Article
Aim To search for a general regionalization pattern using verified records of endemic terrestrial vertebrates. To test previous hypotheses of congruent distribution patterns for Cerrado biotas. To study the role of elevation as a driver of endemism and distribution in the Cerrado region. Location Cerrado domain, central South America. Taxon Tetra...
Article
Documenting species distribution is essential to extinction risk asessments and subsequent conservation actions. Historical records are thus essential to understand how species are distributed and how their range has changed over time. However, using historical records might contribute to overestimating the species current range and misrepresent th...

Effective, resilient and strategic protected area networks are essential to protect biodiversity and human welfare, especially in vulnerable biodiversity hotspots. This is the case in the Brazilian Cerrado, the richest tropical savanna, and a deforestation front worldwide. Worryingly, the rate of habitat conversion in Cerrado greatly reduces opport...
Article
The relationships of the hyline tribe Dendropsophini remain poorly studied, with most published analyses dealing with few of the species groups of Dendropsophus. In order to test the monophyly of Dendropsophini, its genera, and the species groups currently recognized in Dendropsophus, we performed a total evidence phylogenetic analysis. The molecul...

EXECUTIVE SUMMARY The Amazon is the world’s largest rainforest and the largest river basin on the planet. More species are found here than anywhere else. Such is the extraordinary diversity of life in the Amazon that the region is believed to be home to 10%, 1 in 10, known species on Earth. A compilation of species in the Amazon region from 2002 sh...

Spiny-backed tree frogs of the genus Osteocephalus are conspicuous components of the tropical wet forests of the Amazon and the Guiana Shield. Here, we revise the phylogenetic relationships of Osteocephalus and its sister group Tepuihyla, using up to 6134bp of DNA sequences of nine mitochondrial and one nuclear gene for 338 specimens from eight cou...
Article
Evolutionary processes are known to influence contemporary patterns of biological diversity, yet disentangling the effects of current and historical drivers of biodiversity patterns remain challenging. We use spatial analyses of community dissimilarity to generate hypotheses about the current and historical processes underlying patterns of beta div...

Based on phylogenetic and molecular dating analyses of several species of Cnemidophorus and Ameiva, representing major groups of species of these two genera, we uncover a previ-ously unrecognized Ameiva lineage, which includes described Cnemidophorus parecis from south-western Amazonia. We discuss the diagnosis of Ameiva and Cnemidophorus and the i...
Article
Species distribution patterns result from the combination of multiple factors acting over different spatial and temporal scales. We analyze the distribution patterns of anuran amphibians within the Cerrado domain of South America in a historical framework. First, we provide an updated list of species based on extensive research in zoological collec...

Brazil has a fundamental role in amphibian conservation, harboring the highest amphibian species richness in the world and a large number of endemics. Here, we present an overview of the Brazilian Amphibian Conser-vation Action Plan (BACAP), which is still being developed by Brazilian herpetologists. Basic research ¢ particularly species inventorie...

Os Cerrados sul-americanos abrigam alta diversidade de répteis, incluindo elevado número de endemismos. No entanto, o conhecimento desta diversidade é ainda incompleto frente à acelerada transformação das paisagens naturais no Brasil central. Constituem, portanto, uma das regiões prioritárias para estudo e conservação da biodiversidade mundial. Est...

A porção norte do domínio do Cerrado é uma das áreas historicamente menos conhecidas com relação à sua biodiversidade. Recentemente, alguns estudos tem revelado valores de riqueza comparáveis a outras regiões dentro do domínio. A Estação Ecológica Serra Geral do Tocantins (EESGT) está localizada na região do Jalapão, porção Nordeste do Cerrado, e f...

Basic taxonomic and distributional data on vertebrates are one of the most useful and reliable sources of information for conservation planning. Biological data are even more relevant in rich and highly threatened regions such as the Brazilian Cerrado, one of the least studied global biodiversity hotspots. Herein we provide a summary of the results...

The South American Cerrado harbors a rich reptilian fauna with high number of endemics. However, knowledge of this diversity is still incipient in front of accelerated transformation of natural landscapes, which makes the domain a "hotspot" for study and conservation of global biodiversity. Studies on the reptile fauna of Cerrado are urgently neede...

The Northern part of Cerrado is one of the biologically poorest known areas in the domain. Recent studies revealed richness values that are as high as those from other sites in the domain. The Estação Ecológica Serra Geral do Tocantins is located in a region known as Jalapão, in Northeastern Cerrado, and it is included in the largest set of protect...

Inventories of fauna directly access the diversity of a locality in a certain period of time. The primary data generated by these inventories comprise one of the most important steps in decisions making regarding the management of natural areas. However, several problems have been observed at different levels related to inventories of fauna in Braz...

Global priority areas have already been defined by the congruence between endemism and threat in major terrestrial regions. However, detailed analyses refining these data and detecting priorities for site-scale action are still badly needed. One of the main data requirements for the selection of priority sites are compilations of detailed data on t...

The contact zone between Cerrado and Caatinga is among the least known areas in the Cerrado biome, andno information is available about the anuran species occurring in this area and their ecology. Along this area, seasonallydry tropical forests are common on the lowlands with some enclaves inside the Cerrado core area. Here, we present forthe first...

Lizard richness, composition and local distribution were studied in a 6000 ha preserved tract of Cerrado in central Brazil. Recorded richness, with 17 species in seven families, is higher than most presented for Cerrado localities. The lizard assemblage is significantly structured in terms of local distribution, being dominated by species with stri...

We describe a new species of Cnemidophorus from a Cerrado enclave in south-western Amazonia, Rondô nia state, Brazil. This species is apparently endemic to Cerrado enclaves in the vicinity of the city of Vilhena, a region under intensive anthropic pressure due to the expansion of soybean plantations. A discriminant analysis indicated that femoral p...
