During the last two decades, regional exploration coupled with dense geographic sampling,
new molecular techniques, and phylogeographic approaches have led to the discovery of …

During the speciation process sibling lineages accumulate differences in time (eg genetic,
morphological, and/or ecological). Phenotypic traits such as size or shape, however, could …

The diversity of the Patagonian lizard fauna is a combination of low diversity at higher levels,
eg, families, some of them almost marginal to the region, coupled with very high species …

We describe a new sexually monomorphic species of the “Phymaturus patagonicus” group,
called Phymaturus katenke. It lives at about 800 m altitude on basaltic outcrops, in the …

In the present contribution, we revisited the taxonomy and phylogenetic relationships within
the somuncurensis and spurcus clades of Phymaturus lizards. Based on 296 morphological …

The extent of stress caused by acute and chronic environmental disturbances depends on
the adaptive ability of organisms to behaviorally and physiologically adjust to change and on …

In this chapter, we provide a detailed and integrated review of the reproductive biology and
life-history traits related to reproduction of lizards that inhabit the cold and harsh …

In the present contribution, we revisited the taxonomy and phylogenetic relationships within
the somuncurensis and spurcus clades of Phymaturus lizards. Based on 296 morphological …

As a young child, Luciano Avila was curious about animals, over the years he kept a
collection of species that neighbors would find lost in their crop-fields. At that time, the travels …
