Revisiting the historical distribution of Seasonally Dry Tropical Forests: new insights based on palaeodistribution modelling and palynological evidencegeb
Aim To investigate the potential distribution of Seasonally Dry Tropical Forests (SDTFs) during the Quaternary climatic fluctuations; to reassess the formerly proposed ‘Pleistocenic arc hypothesis’…

This study provides the most comprehensive phylogeny of Colubroidea to date, and suggests that SHL values may provide a useful complement to bootstrapping for estimating support on likelihood-based trees.

The phylogenetic and biogeographical hypotheses presented here provide an historical framework to further pursue research on the diversification and assembly of the New World herpetofauna.
DEEP DIVERSIFICATION AND LONG‐TERM PERSISTENCE IN THE SOUTH AMERICAN ‘DRY DIAGONAL’: INTEGRATING CONTINENT‐WIDE PHYLOGEOGRAPHY AND DISTRIBUTION MODELING OF GECKOS

These patterns exemplify how low‐vagility species complexes, characterized by strong genetic structure and pre‐Pleistocene divergence histories, represent ideal radiations to investigate broad biogeographic histories of associated biomes.
Climatic stability in the Brazilian Cerrado: implications for biogeographical connections of South American savannas, species richness and conservation in a biodiversity hotspot
Aim To investigate the historical distribution of the Cerrado across Quaternary climatic fluctuations and to generate historical stability maps to test: (1) whether the ‘historical climate’ stability…
Habitat loss and the effectiveness of protected areas in the Cerrado Biodiversity Hotspot
Abstract The definition of conservation targets is strategic for the protection of biodiversity and must ensure the representativeness and persistence of biodiversity components. This is especially…
Anuran Species Composition and Distribution Patterns in Brazilian Cerrado, a Neotropical Hotspot
The distribution patterns of anuran amphibians within the Cerrado domain of South America in a historical framework is analyzed, providing an updated list of species based on extensive research in zoological collections and fieldwork and exploring patterns of endemism and the distribution of species occurring both in Cerrados and each of the adjoining domains.
12. The Character and Dynamics of the Cerrado Herpetofauna
The earliest work on the herpetofauna of the cerrado is a list of 54 reptiles and amphibians from Lagoa Santa, state of Minas Gerais, prepared by Warming (1892). More than 50 years later, Vanzolini…
Ultrastructural study of spermatozoa of the neotropical lizards, Tropidurus semitaeniatus and Tropidurus torquatus (Squamata, Tropiduridae).
The two species of Tropiduridae are very similar, differing in details such as degree of acrosome flattening, presence of bulging at nuclear base, and arrangement of microtubules in the endpiece.
Squamate richness in the Brazilian Cerrado and its environmental–climatic associations
We investigate patterns of species richness of squamates (lizards, snakes, and amphisbaenians) in the Brazilian Cerrado, identifying areas of particularly high richness, and testing predictions of…
