Abstract

In the 25 years since the last synthesis on this topic was published, there has been a marked increase in the appreciation of exudativory as a primate dietary strategy and investigations of its morphological correlates that appear to be adaptations to exudates as food. At least 75 species of primates consume some exudates. Variability of diet among marmosets and tamarins precludes simple classifications of the former as year-round specialists vs. the latter as always facultative seasonal users of exudates. Differences in exudate use among callithrichines, now also including callimico as an exudativore, are associated with apparent adaptations in gut anatomy and functioning, a suite of dental and jaw features, and some features of socioecology and life-history. Among strepsirrhines, several Nycticebus species are newly known to gouge to eat gum, variability among mouse lemurs in gum use has been documented, but little added work has improved our knowledge of variation in exudate use in galagos. For these taxa, much less is understood about possible morphological, behavioral and life-history adaptations and detailed descriptions of behaviors associated with exudate acquisition are needed from the field. The ability to identify anatomical features that will clarify the role of exudates in the diets of fossil primates remains a major challenge.

Notes

Acknowledgments

First, we thank all of the authors whose hard work tackling the sticky issue of exudativory – and their patience with our nagging – make this an exciting volume. To all the reviewers of the chapters in the book, we are most grateful for the improvements they helped us make to the chapters. We are very grateful to Melissa Higgs at Springer for her endless advice and assistance. Michael Power and George Perry provided helpful comments on this chapter. We would also like to thank our families who put up with our rants and occasional absences as well as providing us with much needed support.
