Based on a bibliographical review, we examined the diets of howler monkeys to compile a comprehensive overview of their food resources and document dietary diversity. Additionally, we analyzed the effects of rainfall, group size, and forest size on dietary variation. Howlers eat nearly all available...

Primate diets have been described on a variety of scales including time spent feeding on different food items, macronutrient intake (e.g., carbohydrates, proteins, and lipids), and albeit to a lesser extent, micronutrient (vitamins and minerals) and toxin intake. Based on studies using these approac...

Food resources consumed by primates vary markedly in nutritional content. As a result, foragers must develop a feeding strategy to select resources that balance energy and macronutrient intake and reduce the consumption of fiber and toxins. In this study, we collected data on dietary patterns, rates...

This study reports on the diet and activity budgets of Central American black howling monkeys ( Alouatta pigra) at Monkey River, Belize. This is a previously unstudied population, close to the southern boundary of the species range, and it provides comparative data on A. pigra from a new study site....

Mammals rely on the metabolic functions of their gut microbiota to meet their energetic needs and digest potentially toxic components in their diet. The gut microbiome plastically responds to shifts in host diet and may buffer variation in energy and nutrient availability. However, it is unclear how...
