No Evidence for Adaptive Differential Sex Allocation in Red Junglefowl (Gallus Gallus)

Carotenoids, Immunity, and Integumentary Coloration in Red Junglefowl (gallus Gallus)

A .—There is widespread interest in the roles that carotenoids play as yolk and shank pigments, antioxidants, and immune-system regulators in chickens, but nothing is known of such functions in the wild ancestors of chickens—the Red Junglefowl (Gallus gallus). We manipulated carotenoid access in the diet of captive male and female Red Junglefowl to investigate its eff ects on the coloration of ...

Social behaviour responses in red junglefowl (Gallus gallus) selected for tameness

Cryptic preference for MHC-dissimilar females in male red junglefowl, Gallus gallus.

An increasing number of studies test the idea that females increase offspring fitness by biasing fertilization in favour of genetically compatible partners; however, few have investigated or controlled for corresponding preferences in males. Here, we experimentally test whether male red junglefowl, Gallus gallus, prefer genetically compatible females, measured by similarity at the major histoco...

Brain gene expression in relation to fearfulness in female red junglefowl (Gallus gallus).

The biology of fear is central to animal welfare and has been a major target for selection during domestication. Fear responses were studied in female red junglefowl (RJF), the ancestor of domesticated chickens. A total of 31 females were tested in a ground predator test, an aerial predator test and a tonic immobility (TI) test, in order to assess their level of fearfulness across different sit...
