Atacama Desert in northern Chile are unique features of one of the driest and possibly …

The trematodes are a species-rich group of parasites, with some estimates suggesting that
there are more than 24,000 species. However, recent interests on the biology of trematodes …

Shell features are key factors for systematics and evolutionary biology studies of freshwater
gastropods. Based mostly on shell morphology, 19 species of the springsnail genus …

Species delimitation in minute freshwater snails is often difficult to perform using solely shell
morphology. The problem intensifies when invasive species spread within the distribution …

Simple Summary In this study, we implemented a multifaceted approach, coupling
phylogenetic, phylogeographical and demographic analyses together with a morphological …

Telmatobius is the most diverse group of anurans in the Andean Altiplano (highlands)
Morphologically, these amphibians have a generally conserved morphology but in turn …

The species that inhabit systems highly affected by anthropic activities usually exhibit this
external influence in their gene pool. In this study, we investigated the genetic patterns of …
