Conserving Golden Lion Tamarin
The Problem
The Golden Lion Tamarin (Leontopithecus rosalia) also known as Golden Marmoset, is a small New World monkey of the family Callitrichidae. Native to the Atlantic coastal forests of Brazil, the Golden Lion Tamarin is an endangered species with an estimated wild population of "more than 1,000 individuals" and a captive population maintained at approximately 490 individuals.

Most of the wild population is confined to the Poço das Antas Biological Reserve, a protected area of swampy forests in the state of Rio de Janeiro. It is an important bastion of the Golden Lion Tamarin, as only 2% of forests in the monkey's original range remains. Furthermore, its existing habitat has been

The target size will enable the population to maintain a high level of genetic diversity (e.g., 90%) over a 100-year period and is a function of the number of founders, potential growth rate of the population during the growth phase, how well the population is genetically managed, and the generation. Thus the target size is calculated specifically for each population using computer models. In golden lion tamarins the target size of the captive population is estimated to be about 480 individuals. Reproduction is slowed during the maintenance phase to keep the population at its target size. Genetic management (that is, the selection of breeding mates based on pedigree analysis) occurs during all 3 phases, although during the earlier phases there may be a higher priority placed on successful reproduction than on genetic issues (that is, who should breed with whom). The development of the captive population for the golden lion tamarin followed such a progression (Figure 2).

To prevent inbreeding every zoo has a studbook .A stud book is a breed registry of animals within a specific breed whose parents are known. The studbook/breeding program is about managing species in captivity.
Several zoos around the world co-operate in the breeding of the golden lion tamarin, moving individuals among the various zoos to prevent inbreeding. Over 50 tamarins a year are born in captivity. Hopefully, it will be possible to introduce many of these to the wild in future years.
