David Bos has characterized major histocompatibility complex (MHC) variation in a population of wild tiger salamanders. Despite MHC monomorphism in immunodeficient axolotls (Laurens et al. 2001, Eur J Immun 31:506), David found plenty of variation in congeneric tiger salamanders (Bos and DeWoody 2005; Bos et al. 2008). Evidence from a variety of other vertebrates suggests this variation may be maintained by both natural selection and sexual selection (i.e., mate choice). Similarly, Nick Marra has studied the immunogenetics of heteromyid rodents and in so doing has identified a number of genes that might be active targets of selection (Marra and DeWoody 2014). Kendra Abts is identifying MHC genes in koala to benefit their captive breeding program.
