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 ', 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 the grass ''Phragmites communis'', and two other species of grasses (''Echinochloa crus-galli'' 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.〔Pastorini, J., Forstner, M. R. J. and Martin, R. D. 2002. Phylogenetic relationships of gentle lemurs (Hapalemur). Evolutionary Anthropology 11, 150-154.〕 Mitochondrial DNA sequences from the two populations ''H. g. griseus'' and ''H. g. alaotrensis'' are interspersed with each other on the phylogenetic tree.〔Figure 1 of Pastorini, J., Forstner, M. R. J. and Martin, R. D. 2002. Phylogenetic relationships of gentle lemurs (Hapalemur). Evolutionary Anthropology 11, 150-154〕 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.〔NCBI taxonomy database: http://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi〕
The Durrell Wildlife Conservation Trust has a Lac Alaotra bamboo lemur conservation program.
