Wild
Lemurs in the wild are known to vary their habitats and group size depending on their species. For instance, the popular and charasmatic Ring-tailed Lemur runs in female-dominated packs with home territories stretching several kilometers. In a given day they might cover about 1km a day.
While they roam about their home territories, the lemurs mark their territories with scent markers. Males scratch the trees with their wrist spurs while both males and females do hand-stands to rub their genitalia on bushes and trees to leave their scent.
With the forests of Madagascar being 
decimated, the surviving tribes of lemurs are having to make their home ranges closer and closer to each other. Like in the Berenty Reserve, for example, boundries between two aggressive tribes will only be as far apart as 3-5m. This proximity leads to daily clashes, with often violent and bloody repurcussions.
