“…Previous workers who found no sexual dimorphism in canine lengths, (Zingeser, 1973;Milton, 1985a, Kay et al, 1988Rosenberger and Strier, 1989), may have dealt only with northern populations or combined specimens, regardless of their geographical origins. In addition to sexual dimorphism in canine length, we also observed other differences between northern and southern populations.…”

“…Woolly monkeys belong to the ateline subfamily of New World primates, a clade apparently characterized by female dispersal (Rosenberger and Strier, 1989;Strier, 1994). However, although female transfer was confirmed for some populations (Nishimura, 1990;Stevenson et al, 1994), solitary adult and subadult males (as well as an all-male group of five individuals) were also noted at one study site (Di Fiore, unpublished data).…”

In the past several decades, the development of novel molecular techniques and the advent of noninvasive DNA sampling, coupled with the ease and speed with which molecular analyses can now be performed, have made it possible for primatologists to directly examine the fitness effects of individual behavior and to explore how variation in behavior and social systems influences primate population genetic structure. This review describes the theoretical connections between individual behavior and primate social systems on the one hand and population genetic structure on the other, discusses the kinds of molecular markers typically employed in genetic studies of primates, and summarizes what primatologists have learned from molecular studies over the past few decades about dispersal patterns, mating systems, reproductive strategies, and the influence of kinship on social behavior. Several important conclusions can be drawn from this overview. First, genetic data confirm that, in many species, male dominance rank and fitness are positively related, at least over the short term, though this relationship need not simply be a reflection of malemale contest competition over mates. More importantly, genetic research reveals the significance of female choice in determining male reproductive success, and documents the efficacy of alternative mating tactics among males. Second, genetic data suggest that the presumed importance of kinship in structuring primate social relationships needs to be evaluated further, at least for some taxa such as chimpanzees in which demographic factors may be more important than relatedness. I conclude this paper by offering several suggestions of additional ways in which molecular techniques might be employed in behavioral and ecological studies of primates (e.g., for conducting "molecular censuses" of unhabituated populations, for studying disease and host-parasite interactions, or for tracking seed fate in studies of seed dispersal) and by providing a brief introduction to the burgeoning field of nonhuman primate behavioral genetics.

“…Energy is often proposed to be the primary driver behind atelines' diet selection (Di Fiore and Rodman 2001;Rosenberger and Strier 1989;Strier 1992), because they frequently select and ingest large volumes of fruits that are rich in lipids and soluble carbohydrates (Castellanos 1995;Dew 2005). In contrast to this view and other major schools of thought in nutritional ecology (Dearing et al 2005;Freeland and Janzen 1974;Mattson 1980;Schoener 1971;White 1993), Felton et al (2009b) determined that spider monkeys (Ateles chamek) in La Chonta, Bolivia, select diets that supply a set amount of protein, rather than attempting to maximize the ingestion of energy or protein, or to regulate plant secondary metabolites.…”

Nutritional Ecology of Ateles chamek in lowland Bolivia: How Macronutrient Balancing Influences Food Choices

et al. 2009

All free-living animals must make choices regarding which foods to eat, with the choices influencing their health and fitness. An important goal in nutritional ecology is therefore to understand what governs animals' diet selection. Despite large variation in the availability of different food items, Peruvian spider monkeys (Ateles chamek) maintain a relatively stable daily protein intake, but allow total energy intake to vary as a function of the composition of available food items. This is referred to as protein-dominated macronutrient balancing. Here we assess the influence of this nutritional strategy on daily and seasonal nutritional intakes, Int J Primatol (2009) We conducted continuous all-day observations of focal spider monkeys inhabiting a semideciduous forest in Bolivia. We recorded feeding events, collected foods, and analyzed their nutrient content. By using the Geometric Framework for nutrition, we show that individuals reached their daily end-point in nutrient space -balance between protein and nonprotein energy intake-by consuming nutritionally balanced foods or by alternating between nutritionally complementary foods. The macronutritionally balanced figs of Ficus boliviana were their primary staple food and therefore dominated their overall nutritional intake. Our results also demonstrate that spider monkeys consumed a diverse array of ripe fruits to overcome periods of fig scarcity rather than vice versa; they could obtain sufficient protein on a diet of pure fruit; and unripe figs constituted a nutritionally rewarding and reliable food resource. We hope that the approaches taken and the conclusions reached in this study will catalyze further inquiries into the nutritional ecology of frugivorous primates.
