“…Secondly, arthropods are highly nutritious [Rothman et al, 2014;Bryer et al, 2015] and, following Janson and Chapman [1999] and Smythe [1982], are expected to be relatively homogenously dispersed in the environment. We found no evidence for the latter, as it seems to us that they are patchily distributed, depending on the tree species.…”

“…Few studies have examined the impact of arthropod availability over time on the diet of primate species [Stone, 2007;Bryer et al, 2015]. Stone [2007] observed seasonal changes in diet and foraging behaviours of two groups of squirrel monkeys (Saimiri sciureus): she found no seasonal shifts in arthropod abundance related to rainfall and [Pickett et al, 2012;Mallott et al, 2015].…”

“…Nonetheless, nutritional analysis of fruits and arthropods can help us to obtain a better understanding of what factors influence food selection in woolly monkeys and the trade-off between foraging and nutritional needs for this species, as arthropods are higher in protein than fruits and leaves [Bryer et al, 2015], but may also provide monkeys with micronutrients and contribute a substantial nutritional payoff for minimal feeding effort [Rothman et al, 2014].…”

The woolly monkey’s (Lagothrix lagotricha) diet consists primarily of fruits, and for some populations fruit availability predicts its frequency in the diet. Woolly monkeys also eat new leaves, flowers, seeds and arthropods, but it is unclear whether arthropods are consumed in proportion to their environmental availability. We tested the hypothesis that arthropod consumption by woolly monkeys depends on availability. We studied a group of woolly monkeys for 10 months in 2013–2014, in Cueva de los Guácharos National Park, Colombia, in order to test the hypothesis that arthropod consumption by woolly monkeys depends on availability. We carried out surveys of plant phenology each month for 10 months to estimate fruit productivity, and every 2 months we also surveyed 3 canopy substrates (leaves, mosses and bromeliads) to quantify variation in arthropod biomass. During this time, we also quantified the diet of a woolly monkey group. The items most consumed were fruits (60%), followed by arthropods (24%), leaves (13%) and miscellaneous other items (3%). Arthropod biomass in the canopy did not vary considerably over the 10 months (0.014–0.037 g/g substrate) but was lower at the end of the second rainy season. A positive correlation was found between availability and entomophagy, but only when arthropods were relatively abundant. We did not find a relationship between arthropod and fruit feeding frequencies. Our results indicate that arthropods are prevalent in the diet of the woolly monkeys due to their abundance in Andean forest canopies.

“…These patches are likely to be more rapidly depleted by monkeys at Issa—particularly given the larger group size of K0—resulting in greater daily search effort and a larger home range to meet subsistence needs (Wrangham et al, ). Similar to other sites, insects likely comprise an important component of red‐tailed monkey diet at Issa (Bryer, Chapman, Raubenheimer, Lambert, & Rothman, ; AP unpublished data). Insects are typically more uniformly distributed but harder to locate than fruit, flowers, and leaves (Chapman & Chapman, ).…”

Objectives: Primates that live in predominantly forested habitats and open, savanna mosaics should exhibit behavioral responses to differing food distributions and weather. We compared ecological constraints on red-tailed monkey ranging behavior in forest and savanna mosaic environments. Intraspecific variation in adaptations to these conditions may reflect similar pressures faced by hominins during the Plio-Pleistocene.Methods: We followed six groups in moist evergreen forest at Ngogo (Uganda) and one group in a savanna-woodland mosaic at the Issa Valley (Tanzania). We used spatial analyses to compare home range sizes and daily travel distances (DTD) between sites. We used measures of vegetation density and phenology to interpolate spatially explicit indices of food (fruit, flower, and leaves) abundance. We modeled DTD and range use against food abundance. We modeled DTD and at Issa hourly travel distances (HTD), against temperature and rainfall.Results: Compared to Issa, monkeys at Ngogo exhibited significantly smaller home ranges and less variation in DTD. DTD related negatively to fruit abundance, which had a stronger effect at Issa. DTD and HTD related negatively to temperature but not rainfall. This effect did not differ significantly between sites. Home range use did not relate to food abundance at either site. Conclusions: Our results indicate food availability and thermoregulatory constraints influence red-tailed monkey ranging patterns. Intraspecific variation in home range sizes and DTD likely reflects different food distributions in closed and open habitats. We compare our results with hypotheses of evolved hominin behavior associated with the Plio-Pleistocene shift from similar closed to open environments.

“…It is unclear, however, in squirrel monkeys, whether juveniles are feeding on the same invertebrate taxa as adults (Stone, ). In studies of many wild populations of nonhuman primates, 24–95% of invertebrate prey captures are reported as unknown (Bryer, Chapman, Raubenheimer, Lambert, & Rothman, ; Nadjafzadeh & Heymann, ; Nekaris & Rasmussen, ; Peres, ; Terborgh, ; Urbani, ), and, without specific data on the taxa of prey being consumed, it is difficult to conclude whether or not juveniles and adults have similar predation rates on specific taxa of invertebrates.…”
