Behavioral Ecology


A central question in behavioral ecology is how extent species adapt behaviorally and ecologically to habitat fluctuations in their natural environment and to what extent ecological plasticity is linked to the distribution of species and to speciation. We address these questions in a long-term research program by a comparative and integrative approach applied to nocturnal lemurs which are good models for basal primates.


We aim to understand the traits (e.g. ecology, behavior) that shaped the distribution and adaptation of lemurs. We are also addressing the question of the basis of reproductive isolation of species. These analyses are focused on the genera Microcebus spp., Lepilemur spp. and Avahi ssp. We perform field studies, supplemented by experimental studies, particularly in north-western, northern and eastern Madagascar, using comparable methods, to study the ecology, behavior, parasite infections and the genetics of species showing contrasting distribution, and to assess sensory, ecological and social determinants of species flexibility and its link to genetics.


Female dominance over males is generally defined as the ability of adult females to consistently evoke submissive behavior in adult males on an individual level. Female dominance is a rare trait in mammals and within primates, but seems to be widespread among the lemurs of Madagascar. How and why female dominance evolved in lemurs is discussed controversially. By focussing on natural and experimentally induced social interactions in nocturnal lemur taxa, we explore current hypotheses and analyze proximate factors governing female dominance in this primate group.


The sensitivity and specificity of pheromone perception depends on the olfactory receptor repertoire present in the epithelium of the vomeronasal organ and the main olfactory epithelium. We are interested in evaluating the functional VNO receptor repertoire of the nocturnal mouse lemurs (Microcebus spp.) that are well known for their extensive use of olfactory marking behaviors. We study the variability, selection and phylogenetic ancestry of the VNO repertoire of mouse lemurs and the olfactory perception capacities of this small primate model.


Evolutionary biology, biodiversity and conservation


Lemurs underwent a broad-scale adaptive radiation after their initial colonization of Madagascar about 60 Mya. Extant lemurs consist of more than 100 species which inhabit the various forest habitats of the Island. Many species, in particular nocturnal species, have only been described recently, partly by our group. Whereas some species show quite limited geographic ranges, others show broad distributions. The underlying colonisation history and the factors driving this diversification are so far only poorly known. We aim to understand the factors that promoted this radiation and shaped the distribution, adaptation and genetic structures of lemurs. These analyses are focused on the genera Microcebus spp., Lepilemur spp. and Avahi ssp.


Nocturnal lemurs belong to the endangered primates due to anthropogenic habitat loss, fragmentation, habitat degradation and poaching. We perform field studies to study the abundance, ecology, parasite infections and the genetics of populations of lemurs undergoing different levels of threats in various parts of the island. Long-term study sites include the Ankarafantsika National Park (work since 1995) and the Mariarano forest (work since 2003) that both contain different habitat types, including xerophytic forests, dry deciduous forests, semi-humid gallery forests along rivers or lake shores, coastal mangrove forests (Mariarano) and secondary vegetation formations that may develop after bushfires or selective wood extraction. This mosaic of habitat types offers many different ecological niches for lemurs and other forest dwelling organisms. Knowledge on the environmental flexibility of lemurs is still in its infancy, but urgently needed for conservation management. Comparative studies in various sites deliver important tools to monitor and manage the biodiversity in tropical forests. Furthermore, they will help to understand the evolution of the unique species diversity of lemurs in Madagascar and the origin and evolution of our own primate ancestry.


The development of effective conservation measures for endangered species requires a detailed knowledge of remaining individual numbers, the distribution of species, their ecological requirements, and the factors causing potential threats to their survival. Moreover, it is important to understand the degree of intra-specific differentiation (e.g. phenotypic, ecological, genetic) that can be the result of rather recent (i.e. anthropogenic) or ancient evolutionary processes (e.g., barriers, landscape). We aim to understand the population structure of different lemur species in view of drastic anthropogenic disturbances. Ancient and recent processes of genetic differentiation shall be identified in order to develop effective conservation measures.

In a recent project, we study habitat loss and fragmentation in the context of past and future environmental changes, across taxa and regions mainly in Madagascar with an international team of researchers (see project INFRAGECO and respective link to project web-page).




Marked climatic oscillations between glacial and interglacial periods had worldwide consequences for vegetation as well as animal population dynamics. The importance of these shallow-time (on geological and evolutionary timescales) geographic dynamics for shaping current biodiversity and biogeography patterns is increasingly stressed, although rarely analyzed in an innovative integrated manner. We aim to integrate records of vegetation and climate dynamics with inferred population dynamics to reconstruct the dynamics of forest landscapes and of populations of forest dwelling species over space and time in a primate model endemic to Madagascar.
