Seasonal and habitat effects on the nutritional properties of savanna vegetation
Investigating Niche Construction in Dynamic Human-Animal Landscapes
Grass leaves as potential hominin dietary resources
Impending extinction crisis of the world’s primates
Impending extinction of the world’s primates due to human activities; immediate global attention is needed to reverse the trend.

Evolutionary Biology of Ape and Monkey Feeding and Nutrition
Macronutrient and Energy Contributions of Insects to the Diet of a Frugivorous Monkey (Cercopithecus ascanius)
Fallback Foods, Optimal Diets, and Nutritional Targets
Eating is a risky affair. All animals have to offset risks of feeding such as exposure to plant toxins, increased vulnerability to predation, or conspecific aggression with a food's energetic and nutritional return. What, when, and where an individual eats can impact fitness and, ultimately, species-level adaptations. Here, we explore the variables that influence primate feeding preference: food availability, chemical defense, and nutrient conten…

Are Primates Ecosystem Engineers
In Vitro Fermentation of Dietary Carbohydrates Consumed by African Apes and Monkeys
Primate seed dispersers as umbrella species
Almost half of the world's extant primate species are of conservation concern [IUCN, International Union for the Conservation of Nature Red List of Threatened Species, 2008 ]. Primates are also effective seed dispersers. The implications of and interactions between these two facts are increasingly understood, and data demonstrating the consequences of losing primates for forest ecology are now available from throughout the tropics. However, a rea…
Primate frugivory and seed dispersal
Summary to the symposium issue
In this discussion, I evaluate our understanding of fallback foods in primate and hominin ecology and evolution with reference to the challenges of nomenclature, scale, and of linking individual responses to food availability and properties (process) to species traits (pattern). I use these challenges to form the framework of my discussion and ultimately conclude that we situate the discussion of primate fallback strategy into a broader, “synthet…
Measuring physical traits of primates remotely
Physical traits, such as body size, and processes like growth can be used as indices of primate health and can add to our understanding of life history and behavior. Accurately measuring physical traits in the wild can be challenging because capture is difficult, disrupts animals, and may cause injury. To measure physical traits of arboreal primates remotely, we adapted a parallel laser technique that has been used with terrestrial and marine mam…
The Biology and Evolution of Ape and Monkey Feeding
Seasonality, Fallback Strategies, and Natural Selection
Within this evolutionary framework, we can reasonably assume that feeding-related features observed in extant primates should be, at least in theory, demonstrably the result of natural selection. It is the demonstrable aspect of this important assumption that those concerned with dietary adaptations in the present and in the evolutionary past must confront. In addition to information derived from morphology, it is a truism that scientists studyin…
Primate and Dung Beetle Communities in Secondary Growth Rain Forests
Thirty Years of Research in Kibale National Park, Uganda, Reveals a Complex Picture for Conservation
Competition, predation, and the evolutionary significance of the cercopithecine cheek pouch
Reports of cercopithecine cheek pouch use and functional significance are largely anecdotal, and to date there have been no investigations into its use by species living in closed forest habitats. Here, I report on cheek pouch use in Cercopithecus ascanius and Lophocebus albigena in the Kibale National Park, Uganda, between July–October 1997. Two hypotheses were evaluated: this feature was selected for because of its role in 1) increasing feeding…
Hardness of cercopithecine foods
We evaluate the hardness of foods consumed by sympatric Cercopithecus ascanius (redtail guenons) and Lophocebus albigena (grey‐cheeked mangabeys), and consider how selection might operate to influence foraging adaptations. Since L. albigena has among the thickest dental enamel in extant primates and is commonly referred to as a hard‐object consumer, we predicted that their diet would be harder than that of the guenon. Data on diet and food hardne…
Red-Tailed Guenons (Cercopithecus ascanius) and Strychnos mitis
Habitat alteration and the conservation of African primates
Tropical forests and the animals they support are being threatened by accelerating rates of forest conversion and degradation. In a continually fluctuating sociopolitical world, it is often impossible to protect areas from such conversion until the political environment is suitable to pursue conservation goals, by which time, the forests have often been converted to other uses. This reality suggests a need for inquiry into which primate species c…

Seed handling in chimpanzees (Pan troglodytes) and redtail monkeys (Cercopithecus ascanius)
Primates are confronted with an array of constraints in feeding on fruit, including the removal of adhesive, energy-rich pulp from seeds. In this paper, I discuss how primates meet this challenge and present data on the fruit-processing and seed-handling behavior of chimpanzees and redtail monkeys in Kibale National Park, Uganda. These data are then related to these species' services as seed dispersers. Particular attention was paid to the method…

Locomotor response to predator threat in red colobus monkeys
Evolutionary and ecological implications of primate seed dispersal
In this paper, we evaluate patterns of fruit eating and seed dispersal in monkeys and apes and draw an important distinction between 1) the ecological consequences of primates as seed dispersers and 2) the evolutionary implications of primates on the seed and fruit traits of the plant species they exploit. In many forest communities, primates act as both seed predators and seed dispersers and are likely to have an important ecological impact on p…
Primates as seed dispersers
Primate digestion
Food is vital for life. It provides nutrients for growth, maintenance, and reproduction, and is the source of energy that drives the chemical reactions occurring in every cell.1,2 However, most food, as it is initially procured, is not in a form suitable for use; it must first be broken down so that it can be transported through cell membranes.1 The breaking down of food molecules via a system of both mechanical and chemical processes so that the…
