Head morphometry of Orestias (Cyprinodontiformes). Response to extreme Southern Altiplano systems?
(Springer, 2020)
The distribution ofOrestias(Cypriniforms) species in the southern western Altiplano (17oS-22oS) is allopatric; the seven species described inhabit different freshwater systems with extreme climatic characteristics and ...

HIGH-ELEVATION ANDEAN ECOSYSTEMS
(ACADEMIC PRESS, 2013)
High-elevation habitats of the South American Andes extend from 11° N to 56° S. These geologically young habitats bear a rich vascular flora, which can be accompanied by abundant mosses, lichens, and hepatics in páramo. ...

Assessing impacts of ecosystem engineers on community organization: a general approach illustrated by effects of a high-Andean cushion plant
(BLACKWELL, 2006-11)
Comparative and integrative tools are of fundamental value in ecology for understanding outcomes of biological processes, and making generalizations and predictions. Although ecosystem engineering has been shown to play a ...
Environmental heterogeneity, not distance, structures montane epigaeic spider assemblages in north-western Patagonia (Argentina)
(Springer, 2017-12)
There is considerable controversy around the patterns and processes that influence spatial variation in taxonomic composition in mountain environments. We analysed elevational variation in the taxonomic composition of ...
Species limits and morphometric and environmental variation within the South Andean and Patagonian Mulinum spinosum species-group (Apiaceae-Azorelloideae)
(Taylor & Francis, 2017-09)
Delimiting species is an important, but frequently difficult aspect of systematics that should be addressed using data from multiple sources. Here we combine morphometric analyses and environmental characteristics to delimit ...
Pinegopora chilensis, a new Permian bryozoan species of the Andean bryozoan province in southwestern Gondwana
(Cambridge University Press, 2019-05)
We studied here a bryozoan accumulation in mixed carbonate-siliciclastic successions of the Cerro El Árbol Formation in the central region of Antofagasta, Northern Chile. These stratigraphic units are characterized by an ...
Testing the divergence-with-gene flow model of ecological speciation in two species of andean hummingbirds
(UniandesMaestría en Ciencias BiológicasFacultad de CienciasDepartamento de Biología, 2010)
The divergence-with-gene-flow model of ecological speciation proposes speciation can proceed despite genetic interchange in populations distributed along environment al gradients, where variable selective regimes act on ...
