Background To unravel the evolutionary history of a complex group, a comprehensive
reconstruction of its phylogenetic relationships is crucial. This requires meticulous taxon …

Abstract The IUCN Red List (RL) provides high-quality conservation assessments for
individual species, yet the rate and scale of environmental deterioration globally challenges …

Speciation rates vary greatly among taxa and regions and are shaped by both biotic and
abiotic factors. However, the relative importance and interactions of these factors are not …

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 …

From the early Miocene, the uplift of the Andes Mountains, intense volcanic activity and the
occurrence of successive periods of dryness and humidity would have differentially …

In the present study, we focus on the phylogeographic pattern, demographic history and
morphological differentiation of Heleobia ascotanensis, a freshwater gastropod restricted to …

Trichomycterus varii new species, is described from a small tributary of the High Andean
Plateau Region, Jujuy, Argentina. The new species is distinguished from other species of …

Tropical mountain forests contribute disproportionately to terrestrial biodiversity but little is
known about insect diversity in the canopy and how it is distributed between tree species …

Desert aquatic species tend to show isolated and disconnected populations due to the
fragmented nature of their environment; however, the morphology of the hydrographic …

High Andean freshwater ecosystems are highly threatened by scarce water availability,
