Inbreeding depression in an asexual population of Mimulus guttatus.

abstract：:Despite the ubiquitous nature of sperm storage in invertebrates, relatively little is known about its costs, or the impact that immune activation can have on a female's ability to maintain viable sperm stores. We explored the effects of an immune challenge on sperm storage under food-limited and ad libitum conditions ...
