Genetic Diversity, Population Structure and Evidence of Genetic Bottleneck in Geoffroea decorticans (Fabaceae): Implications for Conservation

Ecology and Evolution, Volume 16, Issue 5, May 2026.
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 ...

Terrestrial ages of meteorites from the Atacama Desert (Chile) and insights into the past meteorite flux to Earth

Meteoritics &Planetary Science, Volume 61, Issue 4, Page 644-663, April 2026.
Abstract The Atacama Desert in Chile is characterized by its high meteorite density and old meteorite terrestrial ages. In this work, we present new terrestrial ages derived from measurements of the concentration of cosmogenic 36Cl in the metal fraction of 51 ordinary chondrites collected over a 6.8 km2 area located in the Catalina Dense Collection ...

Ribcage Morphology in Native South American Populations From Different Altitudes: Insights From a Global Comparative Framework

American Journal of Human Biology, Volume 38, Issue 2, February 2026.
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

An Integrative Appraisal of the Diversity of the Genus Myotis (Chiroptera, Vespertilionidae) in Chile

Journal of Zoological Systematics and Evolutionary Research, Volume 2026, Issue 1, 2026.
The taxonomy of Chilean Myotis has long been contentious, particularly regarding the status of M. arescens relative to M. atacamensis and M. chiloensis. Here, we use an integrative framework combining genome‐wide single nucleotide polymorphisms (SNPs), morphometrics, and bioacoustics to reassess lineage boundaries and evolutionary relationships in ...
