Biogeography of the lizard genus Tropidurus Wied-Neuwied, 1825 (Squamata: Tropiduridae): distribution, endemism, and area relationships in South America.

Based on comprehensive distributional records of the 23 species currently assigned to the lizard genus Tropidurus, we investigated patterns of endemism and area relationships in South America. Two biogeographic methods were applied, Parsimony Analysis of Endemicity (PAE) and Brooks Parsimony Analysis (BPA). Two areas of endemism were detected by PAE: the first within the domains of the semiarid Brazilian Caatinga, which includes seven endemic species, and the second in the region of the Serranía de Huanchaca, eastern Bolivia, in which three endemic species are present.

On the distribution and conservation of the South American lizard genus Tropidurus Wied-Neuwied, 1825 (Squamata: Tropiduridae).

This study describes and analyzes the distribution of the lizard genus Tropidurus based on an updated database and the current taxonomy. General distributional patterns and endemism are identified, the distributions of several species are expanded and previous failures in the determination of specific names are corrected. I provide distributional maps for all species currently assigned to Tropidurus including all occurrence records collected and critical comments on the patterns documented and conservation.
