Genetic diversity and population structure of the Guinea pig (Cavia porcellus, Rodentia, caviidae) in Colombia [PDF]

open access: yesGenetics and Molecular Biology, 2011
The aim was to establish the genetic diversity and population structure of three guinea pig lines, from seven production zones located in Nariño, southwest Colombia. A total of 384 individuals were genotyped with six microsatellite markers. The measurement of intrapopulation diversity revealed allelic richness ranging from 3.0 to 6.56, and observed ...

Morphofunctional Space of the Forelimb in Caraguatypotherium munozi (Notoungulata; Mesotheriidae): Insights Into Wrist‐Powered Digging

open access: yesJournal of Morphology, Volume 286, Issue 8, August 2025.
Caraguatypotherium munozi displays a distinctive morphofunctional configuration combining high wrist flexor leverage with reduced elbow mechanical advantage—traits consistent with wrist‐dominated scratch‐digging. Multivariate analyses place it outside the core morphospaces of extant locomotor groups.

Surviving in the Amazon Arc of Deforestation: Richness and Defaunation of Mammals in Priority‐Protected Areas of the Brazilian Midwest

open access: yesAustral Ecology, Volume 50, Issue 7, July 2025.
We found rich and compositionally different assemblages of medium and large‐sized mammals in protected areas on the southern edge of Amazon. However, both have high rates of mammal defaunation. We argue that anthropogenic threats in the Amazon Arc of Deforestation are eroding large ungulate populations, especially peccaries.

Blood meal sources of wild and domestic Triatoma infestans (Hemiptera: Reduviidae) in Bolivia: connectivity between cycles of transmission of Trypanosoma cruzi [PDF]

open access: yes, 2016
BACKGROUND: Chagas disease is a major public health problem in Latin America. Its etiologic agent, Trypanosoma cruzi, is mainly transmitted through the contaminated faeces of blood-sucking insects called triatomines. Triatoma infestans is the main vector

Phylogeny, evolution, and systematics of theGalea musteloidescomplex (Rodentia: Caviidae) [PDF]

open access: yesJournal of Mammalogy, 2010
As presently recognized, the genus Galea is composed of 3 species, G. musteloides, G. flavidens, and G. spixii. The most widely distributed species is G. musteloides (the common yellow-toothed cavy), ranging from southern Peru to southern Argentina and from sea level to over 4,000 m elevation. Our current taxonomic and systematic understanding of Galea

Two rodent suborders have evolved missing amino acids in the lipid‐binding region of apolipoprotein E

open access: yesLipids, Volume 60, Issue 3, Page 143-153, May 2025.
Abstract The order Rodentia comprises nearly 45% of all extant taxa, currently organized into 31 living families, some 450 genera, and roughly 2010 species (Kelt & Patton, 2020). Considering that rodents began evolving at least 66 million years ago, it is not surprising that they have diversified into five distinct suborders.
