Presentation of PhD-Project: Energy expenditure and strategies to cope with high seasonality in the African lesser bushbaby, Galago moholi (Galagidae)

Many endothermic species have evolved a strategy to deal with seasonal food shortage and low ambient temperature by entering torpor or hibernation. The African lesser bushbaby, Galago moholi, comply with all the preconditions to use heterothermy. It is a small nocturnal primate, which lives in a highly seasonal habitat with a hot wet-season and a cold dry-season with probably lower food abundance. Furthermore G. moholi is one of the closest relatives of Malagasy lemurs, which are known to undergo torpor and hibernation. Nevertheless, a previous study based on measurements of body temperature of G. moholi failed to find any incidence of heterothermy. However, recent studies have shown that physiological traits are not as fixed as previously thought and physiological parameters can differ even within populations. Furthermore methodology has improved in the last years and allows new insights in an animal’s energy expenditure.
Therefore the presented study aims to investigate the plasticity of physiological parameters (especially of thermoregulation and energy budgets) as well as other adaptations to extreme seasonality (home range usage, feeding ecology and behaviour) in a year round study on G. moholi and I will present you the first data I’ll get during fieldwork from March to June 2009.

Is the Diet of Wild Vervet Monkeys (Cercopithecus aethiops) determined by the ecology or by some cultural traits?

The foraging behaviour of primates is often studied because it varies within populations. It has often been showed that the feeding habits can be transmitted from the mother to the juveniles, however, the ecology and the vegetation present in the home range where the monkeys live seems also to have an importance in the choice of the diet. To assume if the diet of Vervet Monkeys, Cercopithecus aethiops, is determined by the ecology or by some cultural traits, I observed what kind of food six groups of Vervets eat in the wild, especially on which trees they feed. I compared these data taken using the scan method with phenological data taken on reference trees of 14 tree species, which were assumed to be the most consumed ones. Maps of the home ranges were made to estimate the abundance of these species within each territory. It appears that the groups feed in a significantly different way, but they all feed mainly on trees. They show different preferences for the most consumed tree species and item eaten, but these preferences are not always correlated with the abundance of the species or the amount of food carried by the trees. This suggests that the ecology explains quite a bit the diet, but not all, and thus, some cultural traits might also be important to determine the composition of the diet.
