Reproductive biology and conservation of muriquis

Abstract

This paper summarizes some of the major findings on the reproductive biology of one group of northern muriquis (Brachyteles hypoxanthus) at the RPPN Feliciano Miguel Abdala (previously known as the Estação Biológica de Caratinga). Long-term monitoring of individual members of the Matão group, combined with non-invasive fecal sampling to measure hormone levels, provide insights into ovarian function, reproductive seasonality, and factors that influence individual and population reproductive rates. All of these parameters have direct applications for assessing the long-term viability of this population, and for conservation of this critically endangered species. These findings were presented at the first meeting of the Committee for the Conservation and Management of the Muriqui (IBAMA), held in Teresópolis, Rio de Janeiro, in October 2002; more recent data have been added or are included in the references.
