Naming the diversity: taxonomy of current species of Patagonian lizards
No full textThe diversity of the Patagonian lizard fauna is a combination of lowdiversity at higher levels, e.g., families, some of them almost marginal to the region,coupled with very high species diversity concentrated in two genera Liolaemus andPhymaturus, and a high number of endemics. The number of described speciesalmost tripled since Cei?s last and only monograph on Patagonian herpetofauna in1987. But changes were not limited to species numbers; taxonomy changed as studiesof this fauna improved with the use of modern taxonomic techniques and dedicatedfield surveys made to some previously unknown areas. The purpose of thischapter is to provide a taxonomic summary of Patagonian lizards. We include anumber of plates with pictures of poorly known and/or endemic Patagonian speciesprobably never included in any book or publication.Fil: Avila, Luciano Javier.

Diversification and Evolutionary Histories of Patagonian Steppe Lizards
No full textDuring the last two decades, regional exploration coupled with dense geographic sampling, new molecular techniques, and phylogeographic approaches have led to the discovery of unexpected hidden diversity. These data have expanded inferences about evolutionary and demographic processes to explain patterns of geographic genetic distribution, phylogenetic history, and morphological characteristics. This chapter summarizes current knowledge of species boundaries and possible underlying processes, highlighting the extent of hybridization and its possible role for the lack of strongly supported phylogenetic relationships within several species groups.Fil: Morando, Mariana.

Biogeography, Ecology, and Spatial Patterns of Patagonian Lizards
No full textPatagonia has a great diversity of lizards, including 6 families, 11 genera and 163 species. The majority of this diversity with documented geographical records corresponds to the Liolaemidae family (Phymaturus and Liolaemus). Latitudinally, lizard richness is higher between 37° to 39° S, decreasing gradually until latitude 54° S; longitudinally, it is higher between 69° and 71° W. The georeferenced records and the number of collected specimens have some biases, with higher values in the northern regions (up to latitude 42° S). However, there are areas up to latitude 45° S with species richness similar to others with a greater number of collected individuals. The vegetation units with the highest species richness (S) in Argentinean Patagonia are the northern and central areas reaching west of Chubut Province: Western District (S = 60) and Typical Southern Monte (S = 49), passing through areas with intermediate richness and with only one species (Wet Magellanic Steppe) or none (Evergreen shrub, Monte?s Mountains and Valleys, Western Interior Pampa, and Peat Bogs). There is a general trend towards lower species richness in vegetation units located in the extreme south of Argentina and south of latitude 41° S in Chile. We evaluated differences in lizard diversity and evenness among vegetation units through a dendrogram based on species incidences and found 6 clusters. Then, we compared species richness between members of each cluster with rarefaction curves. Species marginally distributed in Patagonia have a narrower altitudinal range than Patagonian endemics. Species in genus Liolaemus have small differences in altitudinal range, but species of Phymaturus have pronounced differences in altitudinal ranges. Our spatial analyses, based on intensive systematic-taxonomic activity over the last two decades, shed light into the understanding of lizard distributions in one of the regions with the greatest diversity of reptiles in the world. We also provide ecological and spatial metrics for an updated list of Patagonian lizards. We highlight that the usefulness of discretizing large volumes of information and geographic space into a synthetic framework allows using quantitative results for the study of spatial patterns of biodiversity, decision-making for design studies, use of resources and creation of protected areas.Fil: Minoli, Ignacio.
