Improved Constraints on Andean Glaciations From the Lake Titicaca Continental Drilling Record

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract Long sedimentary records from tropical lakes provide crucial archives for reconstructing the timing and extent of tropical alpine glaciations, yet robust chronologies beyond the radiocarbon limit (ca. 50 ka) remain scarce. Here, we refine the ca. 350 kyr chronology for Lake Titicaca (Peru‐Bolivia) using radiocarbon dating, optically stimulated

The First Archaeomagnetic Age at Tiwanaku and Implications for Dating Andean Metallurgical Furnaces

Archaeometry, Volume 68, Issue 3, Page 317-329, June 2026.
ABSTRACT This paper presents the first archaeomagnetic dating at Tiwanaku (Andean Altiplano). We compared the geomagnetic field values recorded by a metallurgical furnace against an updated SHAWQ2k‐SH global model and a regional intensity curve, both of which include, for the first time, high‐quality intensity data from the Southern Hemisphere.

Relationship between the genetic structure of the Andean toad Rhinella spinulosa (Anura: Bufonidae) and the northern Chile landscape (21°- 24° S) Relación entre la estructura genética del sapo andino Rhinella spinulosa (Anura: Bufonidae) y el paisaje del norte de Chile (21°- 24° S)

Revista Chilena de Historia Natural, 2011
We analyzed the relationship of landscape and environmental features on the genetic differentiation of Rhinella spinulosa (Wiegmann, 1834) in the Altiplano of Antofagasta (Chile).

Endemic human fasciolosis in the Bolivian Altiplano

Epidemiology and Infection, 2006
SUMMARYFasciolosis, caused by trematodes of the genusFasciola, is an emerging disease of humans. One of the highest levels of human fasciolosis hepatica is found amongst the indigenous Aymaran people of the Northern Bolivian Altiplano. A meta-analysis of epidemiological surveys from 38 communities in the region demonstrates that fasciolosis has been ...

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico

Conservation Biology, Volume 40, Issue 3, June 2026.
Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

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.

“Humanizar”: aprendizajes sobre alteridad, salud y futuro en una experiencia de investigación compartida

The Journal of Latin American and Caribbean Anthropology, Volume 31, Issue 2, June 2026.
ABSTRACT The visit to Bogotá of a fééeneminaa (Muinane) friend, Célimo Nejedeka Jifichíu, and in particular, his work in researching and transmitting traditional health knowledge, offer the pretext to navigate the relationship between elements that at first glance seem distant from each other: indigenous imaginaries about otherness, their visions of ...

Photothermal Macroporous Lignin Cryogels for Off‐Grid, Continuous Atmospheric Water Collection via Interlayer Heat Recovery

Advanced Functional Materials, Volume 36, Issue 30, 13 April 2026.
Photothermal, macroporous lignin‐based cryogels are engineered to convert sunlight into low‐grade heat. Integrated as stacked beds in a drum‐type device, a thin copper interlayer transfers waste heat between beds, enabling interlayer heat recovery and continuous solar cycling.
