| Sumario: | Madagascar is a biodiversity hotspot, containing a large proportion of endemic species. To make conservation efforts more effective, it is necessary to understand the spatial distribution of this huge biodiversity. In this study, the patterns of morphological variation and diversity in the adult anurans of Madagascar were evaluated and compared across different climatic regions. These patterns were investigated for 370 species (2360 specimens), and the variation in 13 morphological traits obtained from taxonomic databases was assessed. The results revealed differences in body size distribution across climatic regions and that the most morphologically distinctive species occur in humid regions. The analysis also showed that anuran assemblages tend to be more species-rich, more morphologically diverse, and more morphologically clustered in tropical rainforests. These patterns are attributable to regional variations in the amount and seasonality of precipitation. An understanding of the complex patterns of spatial diversity could be useful for regional prioritization in the conservation of Madagascan anurans |
