Research Objectives: The goal of the present study is to examine group structure, reproductive success and individual growth and development to assess two sympatric Saguinus spp. These data are evaluated in light of the reproductive system proposed for these callitrichids â strict polyandry, cooperative breeding, reproductive suppression, and single reproducing females â in the context of future genetic studies. As such, we attempted to achieve three specific goals:
-An examination of morphological variation between two sympatric callitrichid species
-An evaluation of age and reproductive status per individual
-A comparison of group compositions, mating systems and dispersal patterns of both species to the expected callitrichid reproductive pattern.
