The Southern Altiplano of Bolivia [PDF]

, 2015
Quinoa has been a staple food for Andean populations for millennia. Today, it is a much-appreciated product on the international health-food, organic and fair-trade food markets. Quinoa producers in the southern Altiplano of Bolivia initiated this change approximately 40 years ago.

Recurrent Body Shape Patterns in Cave‐ and Surface‐Dwelling Trichomycterid Catfishes

Journal of Morphology, Volume 287, Issue 9, September 2026.
Multivariate shape analyses reveal that body shape consistently differs between cave‐ and surface‐dwelling trichomycterids in northeastern Colombia, with cave species exhibiting fusiform bodies while surface species showed deeper shapes consistently in different clades.

Mapping the Crustal Thickness of the Andes Using pmP Phases Identified From Adaptive Teleseismic Array Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Crustal thickness (or Moho depth) is a key parameter for many geological and geophysical models. Despite this we have a limited number of measurements, typically from seismic receiver functions, to constrain variations in crustal thickness.

Simultaneous Megapluvials in Southwestern North and South America During the Last Millennium

Paleoceanography and Paleoclimatology, Volume 41, Issue 9, September 2026.
Abstract Earth's climate has experienced prolonged hydroclimatic extreme events that can manifest decadal or longer anomalies. Such events can shape ecological systems and human societies. Decadal‐scale droughts, megadroughts, occurred in southwestern North and South America (North American Southwest, NASW; South American Southwest, SASW) over the past

Building the Andean Crust at ∼35°S: Arc Geochemistry Reveals Cretaceous Thinning and Rapid Neogene Thickening

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Quantification of the timing and mechanisms of crustal thickening in Cordilleran orogenic hinterlands remains challenging. We address this in the Andes using whole‐rock geochemistry and zircon petrochronology from a >70 Myr volcanic record in the Tinguiririca valley of Chile (∼35° ${}^{\circ}$S), which captures a pivotal transition from ...
