The World's Top 25 Most Endangered Primates- 2002

A recent report released by Conservation International (CI) and the Primate Specialist
Group of IUCN was finalized at the 2002 International Primatological Society meetings
in Beijing. It is a revision of their previously released "The World's Top 25 most Endangered Primates",
which indicates that about one out of every three primate species is currently
threatened with extinction.  This updated version suggests that Indonesia now exceeds
Madagascar and Brazil for the country with the most endangered primates.  However,
Madagascar, identified as one of the world's biodiversity hotspots, has 10 critically endangered
species, and 21 endangered species.  For the full report, please refer to the link at the bottom
of this message.

Each week, we will be featuring one of the 25 primate species in peril.  This is being
done in conjunction with Conservation International.  The fact sheets are compiled by
Sean Flannery at the WPRC Library and Information Service.

Black-faced Lion Tamarin (Leontopithecus caissara)

Photo Link:

Save for rediscovery of the yellow-tailed woolly monkey in the Peruvian Andes in the 1970s,
the discovery of Brazil's black-faced lion tamarin in 1990 was perhaps the most newsworthy
event in Neotropical primatology of the 20th century. Despite extensive exploration and
development in the Atlantic forest region of southeastern Brazil, this diminutive, yet conspicuous,
species remained undetected in coastal forests that are incredibly close to S?o Paulo, South
America's largest city. The discovery was made in Superag?i National Park, a protected island
in the Brazilian state of Paran? and still the single most important stronghold for this species
more than a decade after it was found.  Surveys in the mainland forests of Paran? and the
neighboring state of S?o Paulo have dismissed earlier claims of populations in Jacupiranga
State Park and have narrowed the presumed range of this lion tamarin. Population estimates
remain in the low hundreds, but there is hope that continued field research will lead to the discovery
of new mainland populations. The little that we do know about black-faced lion tamarin conservation
status, ecology and behavior is based upon studies conducted by the Brazilian non-governmental
organization, Instituto Pesquisas ?cologicas (IP?), directed by Claudio and Suzana Padua.
