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 …

During the Pleistocene and Holocene, the southwest Andean Altiplano (17°-22° S) was
affected by repeated fluctuations in water levels, high volcanic activity and major tectonic …

This study presents phylogenetic molecular data of the Chilean species of Orestias to
propose an allopatric divergence hypothesis and phylogeographic evidence that suggests …

Orestias ascotanensis is a killifish endemic to the Ascotán salt pan in the Chilean Altiplano,
where it inhabits 12 springs with different degrees of isolation. This species is a suitable …

Orestias is an endemic fish genus of lacustrine and lotic systems distributed on the Andes
highland region (Altiplano) of Peru, Bolivia and Chile (9° S to 22° S). Based on …

The distribution and diversification processes of freshwater fishes have been influenced by
tecto‐volcanic and climatic events that have in turn promoted genesis, destruction, and …

Patterns of molecular genetic differentiation among taxa of the “agassii species
complex”(Parenti, 1984) were analysed based on partial mtDNA control region sequences …

The southern high Andean systems of the Altiplano range from 17 to 22 S and from 3000 to
about 4500 m in altitude. This region is hypothesized to represent the remnants of …

The impact of recent habitat fragmentation on population genetic diversity and structure has
often been studied, mainly related to anthropogenic causes; however its long-term effect has …

Background Studies of the phylogeography of Mexican species are steadily revealing
genetic patterns shared by different species, which will help to unravel the complex …
