Resumen:
Two yellow fever outbreaks (YFOs) ocurred in northeastern Argentina between November 2007 and
October 2008, seriously affecting populations of two howler monkey species: the brown howler Alouatta
guariba clamitans and the black howler Alouatta caraya. Both howlers live syntopically in El Pinalito
Provincial Park, Misiones, where four groups (36 individuals) were studied since January 2005. The
first dead howlers were found on January 20, 2008, in El Pinalito. Systematic searches found 14 dead
howlers within the area (12 from the study groups and two from neighboring groups), with only two
young seen on January 25, 2008, and none found since up to December 2008. In October 2008, another
YFO hit howler monkey populations from El Soberbio, Misiones. Overall, 59 howlers were found dead
in Misiones from November 2007 to December 2008. Thanks to the alert of the howlers death in
El Pinalito, a prompt human vaccination campaign started in the area. Wild howler monkey
populations from both species are in a delicate situation in Misiones, especially the brown howler, an
already endangered species in Argentina and endemic to the Atlantic Forest. If we add the recurrence of
YFOs to the reduction of suitable habitat to small fragments, it could be only a matter of time until
howler populations disappear from the Upper Parana´ Atlantic Forest in Misiones.
