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

Am J Hum Biol
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]

Med Vet Entomol
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.
