Ring-Tailed Lemur

Ring-Tailed Lemur

Ring-tailed lemurs have overlapping home ranges, averaging 1,000m, that are seasonally expanded depending on habitat and habitat quality.

Ring-tailed lemurs are nomadic and travel daily in search of food. They have a daily home range of 1,000 meters, or 0.621 miles from where they awoke as they slowly meander from just before dawn until dusk. One group will use the same part of its home range for three or four days before moving to another part.

The home range size of the ring-tailed lemur varies, depending on habitat, and average size ranges from 0.1 to 0.35 kilometers², or 0.039 to 0.135 miles². In drier or more disturbed habitats, home range sizes are larger, averaging 0.32 kilometers², or 0.124 miles², compared to wetter habitats where ring-tailed lemurs have home ranges averaging 0.17 kilometers², or0.066 miles².

Ring-tailed lemurs seasonally expand their home ranges. During the dry season they utilize larger areas because of the resource scarcity.

The home ranges of multiple groups of ring-tailed lemurs tend to overlap, and there are few areas that are exclusively used by only one group.

Population density is also linked to habitat quality. In wetter, lusher areas, there are more ring-tailed lemurs per square kilometer, up to 350 per kilometers² (135 per miles²), compared to dry or disturbed areas that can have densities as low as 17 per kilometers², or 6.56 per miles².
