Abstract

The target of this study is to evaluate the genetic structure and dispersal patterns of two populations of the black-faced lion tamarin (Leontopithecus caissara), which occur in the coast of São Paulo and Paraná. The construction of a navigation channel in 1953 within the geographic range of this primate species created the Superagüi Island and apparently blocked genetic interchange between the populations. The mainland and Superagüi Island population are 150-180 individuals in size. Genetic analysis of blood samples from 10 and 34 individuals (mainland and island, respectively) were performed through six microsatellite markers and revealed significant difference between these populations. However, the unbalance nature of the sampling may lead us to unrealistic conclusions. Thus, we intend to enlarge sample size at mainland and increase the number of microsatellite markers from six to ten. We also aim to investigate the occurrence of sex-biased dispersal within a single population and the degree of genetic contribution of successful dispersers. Studies on cogeneric species revealed that males disperse more than females and a high proportion of dispersers contribute to future generations. Information is no available for L. caissara. (AU)
