Orestias ascotanensis is a killifish endemic to the Ascotán salt pan in Chilean Altiplano, where it inhabits 12 springs with different degrees of isolation. This species suitable model for studying effect serial geographical isolations on differentiation process among populations. The present study examines genetic variation and structure using mitochondrial DNA control region sequences eight microsatellite loci, analyzing populations across its distribution range. evaluation revealed high...
There is scarce documentation of the presence trout in Puna and southern Altiplano Chile, spite risk that they represent for these ecosystems high environmental value, which have endemic highly threatened fish amphibians.We report Oncorhynchus mykiss has expanded its range to entire Chilean Salmo trutta occurs only extreme south Puna.The existence culture stations related feral trout, cohabit with native amphibians.The control expansion, by protecting areas value banning any future...

Vanessa carye (Hübner, [1812]) has been reported to have a wide latitudinal range from Venezuela the south of Chile (Patagonia). Populations are established at 3500 m in Putre region Chile, with occasional observations around 4500 m. This article reports new elevational record V. above 5200 located Sora Pata Lake, northeast Caquena, highlands Chilean altiplano. finding is highest population ever for this migratory butterfly and one genus .
The Andean Altiplano, characterized by its extreme climatic conditions and high levels of biodiversity, provides a unique environment for studying ecological evolutionary adaptations in insect morphology. Butterflies, due their large wing surface compared to body surface, wide distribution among geographical area given the flight capabilities provided wings, constitute good biological model study morphological following weathers. This focuses on Phulia nymphula, butterfly species widely...
Desert aquatic species tend to show isolated and disconnected populations due the fragmented nature of their environment; however, morphology hydrographic basins, added humid climatic conditions, can allow dispersion between in a desert environment. The aim this study was examine influence drainage on phylogeographic structure gene flow (using fragment mitochondrial control region seven microsatellite markers) an endemic taxon Andean Precordillera Atacama Desert, frog Telmatobius pefauri. We...
Itylos titicaca (Weyner 1890) has been reported to have a narrow distribution range associated with Andean wetlands called “bofedales” in Peru, Bolivia, northeast Chile and northwest Argentina. In its is between the upper Puna lower Alpine belts, recorded from 3800 4900 m. This study reports new elevation record of I. above 5200 m at Sora Pata Lake, Caquena highlands Chilean altiplano. Furthermore, this finding establishes highest report for genus , one family Lycaenidae, several records...
We report the first record of predation on a Helmeted water toad Calyptocephalella gayi tadpole by an adult specimen invasive African clawed frog Xenopus laevis in locality Pichi, Alhué (Santiago Metropolitan Region). This finding is discussed light new sightings, which both species have been detected to coexist different localities central Chile.
This study summarizes new and historical records of one the least known anuran species from Chilean Altiplano, Pleurodema marmoratum (Duméril & Bibron, 1840). The discovery a population in Altiplano Región de Antofagasta extends distribution this Chile approximately 100 km south.
Island ecosystems differ in several elements from mainland and may induce variations related to natural selection patterns of adaptation most aspects the biology an organism. Thylamys elegans (Waterhouse, 1839) is a marsupial endemic Chile, distributed Loa River Concepción. Historically, three subspecies have been described: elegans, coquimbensis soricinus. For this research, two morphometric approaches biomechanical model were used compare mandible shapes biomechanics between Chilean mouse...
