Understanding female social dominance: comparative behavioral endocrinology in the Genus Eulemur
… in lemurs, I observed mixed‐sex pairs of related Eulemur species, and identified two key study groups ‐‐ one comprised of species expressing female dominance and, the other comprised of species (from a recently evolved clade) showing equal status between the sexes (hereafter ‘egalitarian’). …

Sex-specific reproductive strategies in redfronted lemurs (Eulemur fulvus rufus, Primates, Lemuridae)
… unusual group composition of redfronted lemurs (Eulemur fulvus rufus) by combining behavioral, demographic and endocrinological data. In the first of a set of four studies I investigated the applicability of non-invasive endocrine measurements for monitoring ovarian function in wild redfronted …

Behavioural ecology of sympatric lemur species Lemur catta and Eulemur sp. In forest fragments, south-eastern Madagascar
… an introduced hybrid brown lemur population of Eulemur rufus x E. collaris in Malaza gallery forest of Berenty reserve, in comparison with the natural sympatric population of ring-tailed lemurs and red collared brown lemurs, Eulemur collaris, in Ambatotsirongorongo forest and with allopatric …

Primate-Plant Interactions in the Tropical Dry Forests of Northwestern Madagascar: Seed Dispersal and Sensory Ecology of Eulemur fulvus.
… I measure the interrelatedness of brown lemurs (Eulemur fulvus) and the endemic fruits they disperse in the tropical dry forests of Ankarafantsika National Park, northwestern Madagascar. I analyze fruit traits across all fruits consumed by brown lemurs over the course of one year of behavioral …

Lemurs as protectors of the forest: Red-collared brown lemur seed dispersal, forest regeneration, and local livelihoods in the littoral forest fragments of southeastern Madagascar
… the ecology of red-collared brown lemurs (Eulemur collaris) in two littoral forests in southeastern Madagascar (Sainte Luce, Mandena). Since 1999, 14 behavioural studies have been conducted on this lemur species in these littoral forests, focusing on their diet, behaviour, activity pattern, …

Salivary Biomarkers of Acute Stress and Insulin Sensitivity in Nonhuman Primates
… lemurs (Varecia rubra) and mongoose lemurs (Eulemur mongoz). Hormones were analyzed with enzyme kinetic or immunoassays. Our study validated tools for analyzing alpha-amylase, cortisol, and insulin in saliva for those species. No significant relationship was found between sAA and insulin. …

Encounters in the forest: Social and ecological dimensions of lemur hunting, habitat change and biodiversity conservation in south-east Madagascar
… special importance. Red-collared brown lemurs (Eulemur collaris) are targeted for their fatty meat and southern bamboo lemurs (Hapalemur meridionalis) are treated locally as a ‘pest’ species. In my ecological research, I elucidate the impacts of habitat modifications and hunting on endemic …

The use of a novel scent enrichment to improve captive primate welfare and its potential application to conservation breeding
… and odour profiles of zoo-housed crowned lemurs (Eulemur coronatus) and red-ruffed lemurs (Varecia rubra). I also aim to develop a novel, biologically-relevant scent enrichment based on odour profiles. Firstly, I examined the scent-marking behaviours and odour secretions released by lemurs, by …

The Ecology and Evolution of the Folivore Gut Microbiome in Madagascar’s Lemurs
… (Propithecus spp.) and frugivorous brown lemurs (Eulemur spp.). These lineages diverged over similar evolutionary time and live sympatrically in Madagascar’s rainforests and dry forests. Next, I compared GMBs across sympatric species of sifaka (P. diadema), indri (Indri indri), woolly lemur (Avahi …

Variation in susceptibility to parasite infection: patterns, determinants and consequences in red-fronted lemurs
… Parasitenbefall bei frei lebenden Rotstirnmakis (Eulemur fulvus rufus) untersucht um im folgenden mögliche Konsequenzen von individuellem Parasitenbefall auf den Paarungs- und Reproduktionserfolg männlicher Rotstirnmakis zu erforschen. Rotstirnmaki-Männchen fallen durch inter-individuell …
