Parasite life histories influence many aspects of infection dynamics, from the parasite infrapopulation diversity to the fitness of the parasite (the number of successfully transmitted parasites). Studies of medically important parasites, such as the parasite responsible for malaria (Plasmodium spp.), demonstrate the usefulness of investigating the life histories of parasites to better understand infection characteristics such as parasite load and probability of transmission.

The gregarines are a diverse group of apicomplexan parasites that infect invertebrates, and are particularly common in insects and annelids. Given the great biodiversity and importance of their hosts, coupled with their close evolutionary relationship with important …
