Dominant female hyenas enjoy robust immune protection

Previous studies on hyenas have found that the animals can survive rabies, exhibit resistance to anthrax and canine distemper, and don’t generally succumb to fight wounds and infections, possibly because of hyenas’ high numbers of antibodies. New research reported in Functional Ecology finds females, the dominant sex in hyena society, enjoy especially high levels of antibodies, and females have better resistance to bacterial illness than their male counterparts.SmithsonianMag.com (10/6)
