Northern sportive lemur have large bacteria-filled ceca, which helps them to digest plant matter such as cellulose and break it down into sugars and starches. The northern sportive lemur is preyed on by the native Malagasy tree boa, which hunts the lemurs while they are sleeping in tree holes. Large birds of prey, Falconiformes and Strigiformes, are also natural predators of the lemurs. Along with these ecological threats, the arboreal lemur species are also highly threatened by human charcoal production, which still continues to remove the only remaining forest habitat of the lemurs, greatly restricting their range. "L. septentrionalis" is also illegally hunted
Neotropical Birds Online Neotropical Birds Online Neotropical Birds Online is an online encyclopedia whose subject is the bird species that breed in the Neotropics. "Neotropical Birds Online" is patterned after "Birds of North America". Each account profiles a single species, and the accounts are published in the order in which they are completed. The project is sponsored by the Cornell Lab of Ornithology at Cornell University, a leading US research center in ornithology. The list of species covered by "Neotropical Birds Online" is based on the two avian checklist committees of the American Ornithologists' Union: the North American Classification Committee (NACC), which is
