Demography and dispersal patterns of a tamarin population: possible causes of delayed breeding

Published

Journal Article

Saddle-back tamarins Saguinus fuscicollis in Peru live in small groups with 1 reproductive female and 1-2 breeding males. Most animals do not first breed for at least 1yr past the age of potential sexual maturity. Data on survival of adults and lengths of tenure of breeders suggest that breeding vacancies are not frequent. Emigration and survival patterns are not significantly different for the sexes. Delayed first breeding may occur in this species for any or all of the following reasons: a shortage of breeding positions, territories, or helpers; the risks of solitary dispersal; and the inclusive fitness benefits gained from helping. -from Authors
