Isolation of Acanthamoeba Species and Bacterial Symbiont Variability in Puna Salt Plains, Argentina. [PDF]

Environ Microbiol Rep
Acanthamoeba isolated from the extreme environments of the Puna salt plains in Argentina contain unique intracellular microbial communities that are distinct from those found in the surrounding environments. The number of shared taxa amongst intracellular amoebae across all sites was greater than the number of shared taxa between the amoebae and their ...

Linear Plasmids in Micrococcus: Insights Into a Common Ancestor and Transfer by Conjugation. [PDF]

Environ Microbiol
Comparative analysis indicates a common ancestor for linear plasmids in Micrococcus strains from Andean Puna, suggesting that horizontal gene transfer helps native microbes survive extreme conditions. The successful transfer of pLMA1 by conjugation also shows its potential as a genetic vector.

Species Limits and Hybridization in Andean Leaf-Eared Mice (<i>Phyllotis</i>). [PDF]

Ecol Evol
Diversification of Phyllotis coincided with mid‐ to late‐Pleistocene climate change. Species delimitation revealed cryptic diversity within several nominal forms. Genomic analyses revealed evidence for introgressive hybridization. ABSTRACT Leaf‐eared mice (genus Phyllotis) are among the most widespread and abundant small mammals in the Andean Altiplano,

Pollination ecology in the tropical Andes: moving towards a cross-scale approach. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Plant–pollinator interactions structure ecological communities and represent a key component of ecosystem functioning. Pollination networks are expected to be more diverse and specialised in the tropics, but pollination ecology in these regions has been understudied in comparison to other areas.

Geo-structural map of the Laguna Blanca basin (Southern Central Andes, Catamarca, Argentina) [PDF]

, 2015
The Laguna Blanca basin is a rhomb-shaped basin located at the SE margin of the Puna plateau in the southern Central Andes (Catamarca, Argentina). An interactive analysis using remote sensing and field mapping enabled us to produce a geo-structural map ...

Effective elastic thickness in the Central Andes. Correlation to orogenic deformation styles and lower crust high-gravity anomaly [PDF]

, 2018
Global studies have assessed the importance of elastic thickness (Te) on orogenic evolution, showing that the style and nature of upper crustal shortening are influenced by the inherited lithospheric strength. Thus, pioneer works have identified that the
