La estimación de los volúmenes de caída de tefra es fundamental para evaluar los impactos de las erupciones explosivas y el cálculo de los parámetros eruptivos de la fuente (PEF). Las estimaciones están sujetas a incertidumbres que abarcan desde la medición del espesor de los depósitos hasta los diferentes modelos de integración de volúmenes implem...

The South American archaeological record has ample evidence of the socio-cultural dynamism of human populations in the past. This has also been supported through the analysis of ancient genomes, by showing evidence of gene flow across the region. While the extent of these signals is yet to be tested, the growing number of ancient genomes allows for...
Resumen: El agua fue un elemento primordial en el sistema religioso andino pues, por su carácter liminar, enlazaba los ámbitos celeste, terrestre y el interior de la tierra, así como el mundo de los vivos con el de los muertos, además de destacarse por su carácter purificador. La hipótesis que guía este trabajo es la existencia de un axis mundi con...

Asteraceae is the world’s richest plant family and is found on all continents, in environments ranging from the coast to the highest mountains. The family shows all growth forms and, as in other angiosperm families, species richness is concentrated in tropical regions. South America has the highest diversity of Asteraceae in the world, yet taxonomi...

Peatlands are the most carbon-dense ecosystems on earth. In tropical mountains, peatlands are numerous and susceptible to rapid degradation and carbon loss after human disturbances. Quantifying where peatlands are located and how they are affected by land use is key in creating a baseline of carbon stocks and greenhouse gas fluxes from tropical mou...

The Complejo Volcánico Doña Juana – Cascabel National Natural Park is located between the departments of Cauca and Nariño in the southern Andean Region of Colombia. Due to the country’s social challenges and the difficult access to the Doña Juana – Cascabel National Natural Park the biological knowledge concerning groups such as mammals, is based o...

This paper presents an integrative and interdisciplinary approach to the study of ancient agricultural terraces and food production systems. Our approach consists of (1) a resource dependency theoretical framework and (2) the application of a variety of archaeological and geoscientific methods, including archaeological and geomorphological surveys,...
Two African Cixiidae species names, Andes goniodes and Andes synavei proposed by Emeljanov in 2001 to correct two homonymies published by Synave in 1953, are synonymized respectively with Andes muiri and Andes spinifer, which were already proposed as replacement names by Synave in 1970. Additionally, the name Andes synafenni is proposed as new for ...

Andes virus (ANDV), a rodent-borne hantavirus, causes hantavirus pulmonary syndrome (HPS). The safety and immunogenicity of a novel ANDV DNA vaccine was evaluated. Phase 1, double-blind, dose-escalation trial randomly assigned 48 healthy adults to placebo or ANDV DNA vaccine delivered via needle-free jet injection. Cohorts 1 and 2 received 2 mg of ...
