Project: Parasite communities in small-bodied Malagasy lemurs (Microcebus murinus and M. ravelobensis): the effect of sleeping sites, sex and season


This study aims to examine to what extent sleeping site ecology, sex and season affect the parasite communities in two species of the smallest bodied primates, the mouse lemurs. The Grey Mouse Lemur (Microcebus murinus), and the Golden-Brown Mouse Lemur (Microcebus ravelobensis) are of comparable body size, live sympatrically in the dry deciduous forests of northwestern Madagascar, but differ in sleeping site ecology. The goal of this thesis is to establish the parasite load of both species by species prevalence, richness and intensity.  Ectoparasites (such as ticks, lice), blood parasites (such as protozoa) and intestinal parasites (such as helminths) of trapped and individually marked mouse lemurs will be collected for at least three days per individual in the dry and the rainy season using common parasitological field methods. In addition to this, 12 mouse lemurs per species and season will be radiocollared and their sleeping site ecology recorded according to established methods. Fecal samples of each radiocollared mouse lemur will be collected at least once per month to determine intestinal parasites.  Sex and season-specific differences can be detected by a comparison of parasite communities between sexes and seasons.  Species-specific differences linked to sleeping site ecology can be found by comparing the parasite communities of the two species showing comparable body mass and sharing the same habitat.  Findings will give first insight into the link between sleeping site ecology and parasite load in primates and will contribute to a better understanding of wildlife health and conservation medicine.
