| a new species of liolaemus related to l. nigroviridis from the andean highlands of central chile (iguania, liolaemidae). | the liolaemus nigroviridis group is a clade of highland lizards endemic to chile. these species are distributed from northern to central chile, and currently there are no cases of sympatric distribution. this study describes a new species, liolaemus uniformis sp. n., from this group, and provides a detailed morphological characterization and mitochondrial phylogeny using cytochrome-b. liolaemus uniformis was found in sympatry with liolaemus nigroviridis but noticeably differed in size, scalation ... | 2016 | 26877688 |
| deep divergences within liolaemus nigroviridis (squamata, liolaemidae) lineages associated with sky islands in central chile. | evolution of montane species may be strongly influenced by climate oscillations, particularly species distributed in isolated high-elevation areas (sky islands). chilean topography is exemplified by montane environments including the andes and coastal mountains. to test hypotheses related to genetic divergence associated with sky islands, we explored population genetics and phylogenetic signatures in the montane lizard liolaemus nigroviridis müller and hellmich 1932. we sequenced the mitochondri ... | 2013 | 26131464 |
| seasonal flexibility of organ mass and intestinal function for the andean lizard liolaemus nigroviridis. | one of the most fundamental questions in organismal ecology is how animals work in a continuously changing environment. in order to contribute to the current understanding of this question, this study evaluated seasonal changes in digestive enzymes activities, organs size, and energy reserves in liolaemus nigroviridis, a medium-size lizard that inhabit extreme environments in the andes range. we found that digestive enzymes (trehalase, maltase, and aminopeptidase-n) hydrolytic activities, dry ma ... | 2009 | 19204910 |
