Detection of a novel hepacivirus in wild cavies (Cavia aperea aperea)

Archives of Virology
Hepacivirus is a genus of RNA viruses within the family Flaviviridae of which hepatitis C virus (HCV) is the prototype. Several hepaciviruses have been identified in mammals, including rodents of multiple families. Each rodent hepacivirus described so far has been found only in members of a single rodent species.

The Behavioral Endocrinology of Domestication: A Comparison between the Domestic Guinea Pig (Cavia apereaf.porcellus) and Its Wild Ancestor, the Cavy (Cavia aperea)

Hormones and Behavior, 1999
In this study spontaneous behavior and endocrine parameters were compared between the domestic guinea pig (Cavia aperea f. porcellus) and its wild ancestor, the cavy (Cavia aperea), to elucidate the process of domestication in this species. In 120 h of observation time the behavior of five groups of wild and seven groups of domestic guinea pigs, each ...

Haltung und Reproduktion des Wildmeerschweinchens (Cavia aperea)

2015
In this study the effect of two different housing conditions on physiological parameters as well as fetal growth and seasonally different reproductive investment in the wild guinea pig was examined. We found a significant effect of housing condition characterized by a body mass loss and higher basal cortisol levels in animals kept indoors compared to ...

Pair bonding in guinea pigs (Cavia aperea f. porcellus)

2012
Pair bonds are long-lasting selective preferences between two individuals that have a profound impact on physiology and behaviour. The neuropeptide oxytocin (OT) plays an important role as it is involved in pair formation and may suppress maladaptive effects of the stress response.
