Genetic Diversity, Population Structure and Evidence of Genetic Bottleneck in <i>Geoffroea decorticans</i> (Fabaceae): Implications for Conservation. [PDF]
We documented genetic variation, population structure, and bottleneck signals in Geoffroea decorticans (Fabaceae) populations across the Atacama Desert and emphasize the urgency of genetic monitoring. Conservation plans should prioritize populations based on genetic information including those with low diversity, strong bottleneck signals and high ...

Ribcage Morphology in Native South American Populations From Different Altitudes: Insights From a Global Comparative Framework. [PDF]
ABSTRACT Objectives Altitude shapes human morphology as highland populations must cope with cold and hypoxic environments. Although Andean highlanders have been proposed to exhibit larger and deeper ribcages, this idea is mainly based on research using disarticulated skeletal elements or non‐South American controls. The objective of this research is to

Morphological and molecular data on the bat flies, Basilia silvae (Brèthes, 1913) and Trichobius parasiticus Gervais, 1844 parasitizing Chilean bats. [PDF]
We determined morphological and molecularly two species of bat flies: T. parasiticus (Streblidae), and B. silvae (Nycteribiidae). We generated the first sequences for both species in the country for the cytochrome oxidase subunit I. We do recover monophyletic groups for both species, and we discussed the tree topology.

Tracing Human Diversity in South America's Southern Cone: Linguistic, Morphometric, and Genetic Perspectives. [PDF]
ABSTRACT Objectives Studying the relationship between biological and cultural diversity can lead to rich insights into human history. South America has been relatively neglected in this kind of work, even though it intriguingly exhibits unexpectedly high biological and cultural diversity.

BOUNDING MIDDLE PERIOD CEMETERY USE IN SAN PEDRO DE ATACAMA, CHILE [PDF]
ABSTRACTThe San Pedro de Atacama oases, located in northern Chile’s hyperarid Atacama Desert, have been occupied for at least 3000 years. Here, we examine cemetery use in the oases, with emphasis on the Middle Period (ca. AD 400–1000). By modeling of a large corpus (n=243) of radiocarbon dates, over 90% of which are direct AMS assays of human bone ...
