Genetic analysis reveals population structuring and a bottleneck in the black-faced lion tamarin (Leontopithecus caissara).
The ability of a population to evolve in a changing environment may be compromised by human-imposed barriers to gene flow. We investigated the population structure and the possible occurrence of a genetic bottleneck in two isolated populations of the black-faced lion tamarin (Leontopithecus caissara), a species with very reduced numbers (less than 400) in a very restricted range in the Atlantic...
متن کاملForaging behavior and microhabitats used by black lion tamarins, Leontopithecus chrysopyqus (Mikan) (Primates, Callitrichidae)
Foraging in the Black Lion Tamarin (L. chrysopygus Mikan, 1823) was observed in the Caetetus Ecological Station, São Paulo, southeastern Brazil, during 83 days between November 1988 to October 1990. These tamarins use manipuJative, specitic-site foraging behavior. When searching for animal prey items, they examine a variety ofmicrohabitats (dry palm leaves, twigs, under loose bark, in tree cavi...
متن کاملInformative microsatellites for genetic population studies of black-faced lion tamarins (Leontopithecus caissara)
Leontopithecus caissara is a critically endangered primate species from the Brazilian Atlantic Forest. Nineteen microsatellite loci, previously developed for congeneric species, were tested with 34 L. caissara individuals from Superagüi Island. Of the 19 loci, 17 (89.4%) produced robust alleles, nine (47.4%) of these proved to be polymorphic, with a total of 23 alleles and an average of 2.56 al...
متن کاملProgress and problems in Lion tamarin Leontopithecus rosalia rosalia reproduction
In 1972 a conference of biologists from diverse disciplines was held at Washington under the auspices of the Wild Animal Propagation Trust (WAPT), the National Zoological Park, and the New York Zoological Society. Its purpose was to review and summarise information pertinent to marmoset and tamarin biology. It was hoped also that the cross-fertilisation of ideas and knowledge would especially b...
متن کاملIdentifying Important Forest Patches for the Long-term Persistence of the Endangered Golden-Headed Lion Tamarin (Leontopithecus chrysomelas)
As habitat for the golden-headed lion tamarin (GHLT; Leontopithecus chrysomelas) in Brazil’s Atlantic forest becomes smaller and more fragmented, remaining large forest patches may be critical to the persistence of the species. The objectives of our study were to identify the forest patch size that could support a viable population of GHLTs under a range of risk scenarios and to locate patches ...
