Hunting for food and capture for pets also have reduced its numbers through the years. A variety of hunting and trapping methods are employed by local people. Direct pursuit by dogs is the most common, but they may also be captured by using a harpoon, a snare, a stick to knock them out or into the water, or by burning their reed bed habitat, causing them to flee into the hands of waiting hunters. More than 1000 lemurs have been hunted annually in some years (Mutschler et al. 2001).
Lac Alaotra bamboo lemur
The Lac Alaotra bamboo lemur (Hapalemur alaotrensis), also known as the Lac Alaotra gentle lemur, Alaotran bamboo lemur, Alaotran gentle lemur, or locally as the bandro, is a bamboo lemur. It is endemic to the reed beds in and around Lac Alaotra, in northeast Madagascar. This lemur is the only primate specifically adapted to living in papyrus reeds. Unlike other bamboo lemurs, the Lac Alaotra bamboo lemur does not eat bamboo; instead, it feeds on the stems of papyrus reeds, shoots of Phragmites communis, and two types of grasses (Echinocochla crusgalli and Leersia hexandra).
Its tail and body are both 40 cm on average, and it weighs between 1.1 and 1.4 kg, with males slightly larger than females. Its dense, woolly fur is a gray-brown on the back, lighter gray on the face and chest, and chestnut brown on the head and neck.
The classification of the bandro is disputed, with some classifying it as a subspecies of Hapalemur griseus, while others see it as a separate species. Current genetic data do not support species status. Mitochondrial DNA sequences from the two populations H. g. griseus and H. g. alaotrensis are interspersed with each other on the phylogenetic tree. Moreover, average genetic distances between the two subspecies are within the range of within-taxon comparisons and not in the range of between-taxon comparisons. A final assessment of species versus subspecies status requires filling in gaps in sampling and the use of nuclear loci. GenBank, the universal repository for genetic sequence information, has not accepted the species status of the Aloatran lemur and lists it as a subspecies.
