Title
Incest, violence and disease: inbreeding experiment in wild house mice

Abstract
Although inbreeding depression plays a central role in wide range of issues in evolutionary theory and conservation biology, our understanding of its causes and consequences in natural vertebrate populations is still very limited. A plausible but rarely tested mechanism which could contribute to inbreeding depression is if inbreeding increases susceptibility to pathogens and disease. We experimentally tested fitness consequences of inbreeding by comparing pathogen resistance, survival and reproductive success of inbred and outbred wild-derived house mice (Mus musculus domesticus) in a series of infection experiments both in colony and in semi-natural enclosure populations. Our study provides novel experimental evidence for the role of parasites in inbreeding depression and for severe fitness consequences of mating between second-degree relatives in a vertebrate. The results have important implications for the role of parasites in maintenance of genetic diversity and evolution of mating preferences, but also for more applied topics such as conservation biology and human genetic counseling.
