Pre-breeding and breeding season louse infestation intensities and transfers in the 14 male lemurs involved in transfers. Bubble sizes correspond to the combined number of new lice on a lemur as well as previously marked lice recaptured on it. Data for multiple trapping dates have been combined into weeks for simplification. The bracketed area represents the breeding season, with peak breeding occurring in early October. Lines represent louse transfer events, during which one or more lice transferred. Transfer events are always indicated as beginning on the host. Thus, if an individual's louse/lice engaged in multiple transfers (first to a second lemur, then via the second lemur to a third) there will be two lines from the original host on the day the louse was marked - one to the second lemur in the week the louse was recaptured, and one to the third lemur on a different date. Louse intensities began increasing in the population and transfers began occurring two weeks before the peak breeding season.
