The Distribution and Biogeography of the Ringtailed Lemur.
This thesis aims to investigate the behavioural patterns of the ring-tailed lemur, Lemur catta, in two ecologically distinct habitats. L. catta is an appropriate species on which to collect data in relation to primate behavioural flexibility between differing ecological contexts. First, L. catta, a prosimian native to south and southwest.

For over 50 years, ring-tailed lemurs have been studied continuously in the wild. As one of the most long-studied primate species, the length and breadth of their study is comparable to research on Japanese macaques, baboons and chimpanzees. They are also one of the most broadly observed of all primates, with comprehensive research conducted on their behaviour, biology, ecology, genetics.
Ring-tailed lemurs make a variety of sounds, including squeaks, growls, snorts, clicks and howls. When stroked, a tame ring-tailed lemur will purr like a cat. A loud yodel is a territorial claim. All lemurs are threatened because of habitat destruction. The ring-tailed lemur is more abundant than most, inhabiting at least six protected areas.
Ring-tailed lemurs born at the Duke Lemur Center have seen a recent infusion of new genetic material at key genes involved in the immune response, finds a new study. Thanks to a long-term collaborative breeding program that transfers animals between institutions to preserve genetic diversity, genetic variation at one region was restored to levels seen in the wild.
The type of lemur that is adapting to change is the ring- tailed lemur. The ring- tailed lemur is able to adjust because of its ability to adjust to secondary habitats. On the hand, bamboo lemurs are not adjusting well to the changes. They thrive on eating the bamboo found in the forest. Once the bamboo are depleted, they will not be able to.
The most studied lemur, the ring-tailed lemur, has been shown to have blue-yellow vision, but lacks the ability to distinguish red and green hues. Due to polymorphism in opsin genes, which code for color receptivity, trichromatic vision may rarely occur in females of a few lemur species, such as Coquerel's sifaka ( Propithecus coquereli ) and the red ruffed lemur ( Varecia rubra ).
