Late Holocene dynamics of the south American summer monsoon: New insights from the Andes of northern Chile (21°S)
(Pergamon-Elsevier Science Ltd, 2020-10)
The South American summer monsoon (SASM) is the most important climate system of tropical South America, transporting moisture from the tropical Atlantic Ocean to the core of the continent during the austral summer. Recent ...
Phylogeny and diversification of Valerianaceae (Dipsacales) in the southern Andes
(2012)
The southern Andean clade of Valeriana provides an excellent model for the study of biogeography. Here we provide new data to help clarify phylogenetic relationships among the South American valerians, with special focus ...
Influence of the Coupling South Atlantic Convergence Zone-El Niño-Southern Oscillation (SACZ-ENSO) on the projected precipitation changes over the central Andes
(MDPI, 2021-05-08)
There are no studies related to the influence of the coupling between the South Atlantic Convergence Zone (SACZ) and El Niño-Southern Oscillation (ENSO) pattern variability on future changes in the austral summer ...
A review about the quaternary upper-plate deformation in the Southern Central Andes (36–38°S): A plausible interaction between mantle dynamics and tectonics
(Pergamon-Elsevier Science Ltd, 2018-11)
Quaternary deformation in the Southern Central Andes between 36° and 38°S is disconnected, noncontinuous and not particularly tracing the main mountain topographic fronts. This pattern contrasts to the one to the north ...
Vicariance events shaping Southern South American insect distributions
(Wiley Blackwell Publishing, Inc, 2016-09)
The main goal of this study is to use multiple insect phylogenies along with geographical information to test known vicariance hypotheses for Southern South America. We analysed the phylogenies and geographical distributions ...
Ecological and Spatial Patterns Associated with Diversification of the Shrub Genus Tetraglochin along Southern-Central Andes (Rosaceae)
(Springer, 2019-02-26)
In addition to the degree of geographical isolation (sympatry, parapatry, allopatry and peripatry), ecology can be an important factor promoting diversification of lineages, both by niche divergence as well as niche ...
Neotectonic reactivation of the western section of the Malargüe fold and thrust belt (Tromen volcanic plateau, Southern Central Andes)
(Elsevier, 2015)
This study examines the neotectonic deformation and development of the Tromen massif, a Quaternary retroarc volcanic field located in the western section of the Malargue fold and thrust belt in the Southern Central Andes. ...
Birds and endemism in relict forests on western slopes of the North Peruvian and South Ecuadorian AndesAves y endemismo en los bosques relictos de la vertiente occidental andina del norte del Perú y sur del Ecuador
(Universidad Nacional Mayor de San Marcos, Facultad de Ciencias Biológicas, 2005)
First genetic assessment of the level of endemism in the avifauna of the Central Sierras in southern South America
(Wiley Blackwell Publishing, Inc, 2017-05)
The Andes constitute one of the main factors that have promoted diversification in the Neotropics. However, the role of other highland regions in the southern cone of South America has been barely studied. We analyzed the ...
