For those of us who are lucky enough to spend our working lives around these animals, their individual personalities truly touch our souls. In this post I will be looking at why lemurs mean the world to me and what they mean to the world. Let’s face it, lemurs have a lot going for them; firstly they are the most diverse species of primate in the world, ranging from tiny nocturnal mouse lemurs to large haunting Indri, and the Aye […]

I first started loving lemurs when I went on my fourth grade class field trip to The Giraffe Ranch in Dade City, Florida. We got to see a bunch of cool animals and have encounters with wildlife. We saw a rhinoceros get a bath. We fed the giraffes. And an ostrich came right up to our bus. But my favorite encounter was with the ring-tailed lemurs. They were sweet and funny. As we left, they all sat in a little circle […]
At Combe Martin Wildlife Park we care for a group of ring-tailed, black and white ruffed, and red ruffed lemurs. My role as a zookeeper involves everything from preparing the animals’ food, producing exciting enrichment to present it in, to health checking, cleaning and training our groups of lemurs. Believe me when I say that no day is the same! The Beginning of My Love of Lemurs My love of lemurs first manifested four years ago when I began volunteering […]
As part of the Lemur Conservation Action Plan, we are among the leading groups in charge of developing research and conservation in the recently established protected area of Tsitongambarika (south-east corner of Madagascar). This area, where no systematic research has been conducted so far, is considered one of the Action Plan priorities and one of the last large expanses of lowland rainforest left in Madagascar.
Since 1995, we have been studying the proximate and ultimate determinants of day-night activity (aka cathemeral activity) in true lemurs. This activity pattern is extremely rare among primates but common in lemurs, thus offering the unique opportunity to study the key transition between nocturnal and diurnal life during primate evolution.
The lemur species and field sites where we conducted our work on cathemeral activity are:
- Eulemur collaris and Hapalemur meridionalis in the littoral forests of Mandena and Sainte Luce (Fort Dauphin);
- Lemur catta and Eulemur hybrids in the gallery forest of Berenty (Fort Dauphin); and
- Eulemur rufifrons in the dry forest of Kirindy (Morondava).
At the first two sites we have ongoing programs of research.
Studying How Lemurs Respond to Changes in Food Availability and Habitat
A second main stream of our research is focusing on lemur response to change in food availability and habitat disturbance. Since most forested areas in Madagascar have been modified by humans, understanding how lemurs respond to habitat disturbance and/or how they cope with new habitats is urgent. This response is investigated at various levels including thermoregulation, activity and ranging pattern, diet composition and nutritional ecology.
This work uses as a model the archipelago of fragments of the south-eastern littoral forest where the entire lemur community (Eulemur collaris; Hapalemur meridionalis; Avahi meridionalis; Cheirogaleus sp.; Microcebus sp.) has been studied since 1999.
Members of our research groups have also studied the behavioural ecology of Allocebus trichotis and Mirza zaza in Andasibe and Sahamalaza, respectively.
