“…However, invertebrates differ considerably in harvesting costs, modes of acquisition, digestibility, and nutritional benefits; therefore they should not be lumped into a unified category (Ramos-Elorduy et al, 1997;O'Malley and Power, 2014). Rothman et al (2014) found that "hard-bodied" insects contain less dietary energy than do "soft-bodied" insects, such as caterpillars.…”

“…For example, chimpanzees modify and use stick tools to extract termites (Sanz et al, 2004;Wright et al, 2009;Yamagiwa and Basabose, 2009) and different tools to obtain pith and leaves (Malenky and Wrangham, 1994;Wrangham et al, 1998;Yamakoshi, 1998;Basabose, 2002). Modern chimpanzees extract invertebrates regularly (Uehara 1982;Nishida and Uehara 1983;Sanz et al, 2004;Sch€ oning et al, 2008;Bogart and Pruetz, 2010;O'Malley and Power, 2014), and may fall back on them when ripe fruits are scarce (Yamagiwa and Basabose, 2009). In this study, we focus on another lineage of large-brained, tool-using primates with high levels of sensorimotor cognition-capuchin monkeys (Parker and Gibson, 1977;Ottoni and Izar, 2008).…”

Invertebrate foraging patterns are not uniform. Caterpillar consumption is consistent with a preferred strategy, whereas capuchins appear to fallback on invertebrates requiring high handling time. Capuchins are convergent with hominins in possessing large brains and high levels of sensorimotor intelligence, thus our research has broad implications for primate evolution, including factors shaping cognitive innovations, brain size, and the role of entomophagy in the human diet.

“…Vertebrate and invertebrate prey can differ in body size by orders of magnitude, yet can have comparable macronutrient composition when compared on a gram-to-gram basis (DeFoliart, 1989, 1992; O’Malley and Power, 2012). The consumption of animals is likely to yield important nutritional benefits for great apes, yet comprehensive nutritional data of the most common chimpanzee prey are limited to analyses of insects (e.g., Deblauwe and Janssens 2008; O’Malley and Power 2012, 2014). Nutrient deficiencies are likely to have fitness consequences during periods of high reproductive investment such as pregnancy and early lactation, but to our knowledge no published studies have examined how faunivory patterns vary during pregnancy and lactation in chimpanzees or any other great ape species.…”

An increase in faunivory is a consistent component of human evolutionary models. Animal matter is energy- and nutrient-dense and can provide macronutrients, minerals, and vitamins that are limited or absent in plant foods. For female humans and other omnivorous primates, faunivory may be of particular importance during the costly periods of pregnancy and early lactation. Yet, because animal prey is often monopolizable, access to fauna among group-living primates may be mediated by social factors such as rank. Wild chimpanzees (Pan troglodytes) across Africa habitually consume insects and/or vertebrates. However, no published studies have examined patterns of female chimpanzee faunivory during pregnancy and early lactation relative to non-reproductive periods, or by females of different rank. In this study, we assessed the influence of reproductive state and dominance rank on the consumption of fauna (meat and insects) by female chimpanzees of Gombe National Park, Tanzania. Using observational data collected over 38 years, we tested (a) whether faunivory varied by reproductive state, and (b) if high-ranking females spent more time consuming fauna than lower-ranking females. In single-factor models, pregnant females consumed more meat than lactating and baseline (meaning not pregnant and not in early lactation) females, and high-ranking females consumed more meat than lower-ranking females. A two-factor analysis of a subset of well-sampled females identified an interaction between rank and reproductive state: lower-ranking females consumed more meat during pregnancy than lower-ranking lactating and baseline females did. High-ranking females did not significantly differ in meat consumption between reproductive states. We found no relationships between rank or reproductive state with insectivory. We conclude that, unlike insectivory, meat consumption by female chimpanzees is mediated by both reproductive state and social rank. We outline several possible mechanisms for these patterns, relate our findings to meat-eating patterns in women from well-studied hunter-gatherer societies, and discuss potential avenues for future research.

“…Despite its importance, our understanding of the mineral intake and requirements of wild primates is limited [2], [7]. Few studies have investigated the dietary minerals of primates [7], [8], [9], [10], [11], [12], [13], [14], and particularly of apes [15], [16], [17], [18], [19].…”

Minerals in the Foods Eaten by Mountain Gorillas (Gorilla beringei)

et al. 2014

Minerals are critical to an individual’s health and fitness, and yet little is known about mineral nutrition and requirements in free-ranging primates. We estimated the mineral content of foods consumed by mountain gorillas (Gorilla beringei beringei) in the Bwindi Impenetrable National Park, Uganda. Mountain gorillas acquire the majority of their minerals from herbaceous leaves, which constitute the bulk of their diet. However, less commonly eaten foods were sometimes found to be higher in specific minerals, suggesting their potential importance. A principal component analysis demonstrated little correlation among minerals in food items, which further suggests that mountain gorillas might increase dietary diversity to obtain a full complement of minerals in their diet. Future work is needed to examine the bioavailability of minerals to mountain gorillas in order to better understand their intake in relation to estimated needs and the consequences of suboptimal mineral balance in gorilla foods.
