We monitored a population of four to seven groups of individually marked saddle‐back tamarins (Saguinus fuscicollis; Callitrichidae) at the Cocha Cashu Biological Station in Peru's Manu National Park…
Facultative polyandry and the role of infant-carrying in wild saddle-back tamarins (Saguinus fuscicollis)

- BiologyBehavioral Ecology and Sociobiology
The data from this study population tentatively support the hypothesis that adults should mate monogramously only if they have nonreproductive helpers to help rear infants, and the proposed benefits of polyandry to males and females differ quantitatively, but in both cases benefits stem from the help that males provide in rearing young.

SEASONAL FOOD SHORTAGE, WEIGHT LOSS, AND THE TIMING OF BIRTHS IN SADDLE-BACK TAMARINS (SAGUINUS FUSCICOLLIS)
It is suggested that tamarin births at Cocha Cashu are timed such that lactation and weaning occur when food is abundant, because during the period of low food availability, there would be insufficient food to meet the demands of lactationand to serve as easily obtainable weaning foods.

Evidence that disease-induced population decline changes genetic structure and alters dispersal patterns in the Tasmanian devil
The results show that disease can result in genetic and demographic changes in host populations over few generations and short time scales and that dispersal is male-biased in devils and that disperseal distances follow a typical leptokurtic distribution.
Demography and Dispersal Patterns of a Tamarin Population: Possible Causes of Delayed Breeding
It is suggested that 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.
