“…Field observations of frugivorous primates show that rates of arthropod consumption vary significantly, even among species with similar body size. For instance, arthropod consumption in medium-sized (from 2 to 3 kg) platyrrhine primates, such as Cacajao ouakary (Barnett et al 2013), Cebus kaapori Queiroz, 1992(Oliveira et al 2014, and Sapajus apella Linnaeus, 1758 (Fragaszy et al 2004;Gómez-Posada et al 2019), may range from 3 to 50%, and from 1.3 to 23% in large-sized primates (above 7 kg), such as Ateles belzebuth É. Geoffroy Saint-Hilaire, 1806 (Link 2003), and Lagothrix lagotricha Humboldt, 1812 (Stevenson et al 1994). More precise information based on large sample sizes is required to adequately assess the importance of arthropod consumption in primates of varying body sizes.…”

Terrestrial arthropod groups, including insects, spiders, and millipedes, represent an important food resource for primates. However, species consumed and patterns and rates of arthropod-related feeding for most frugivorous primates are still poorly known. We examined stomach contents of 178 Amazonian primate specimens of nine genera and three families obtained from community-based collections voluntarily donated by subsistence hunters. Based on our results, we assessed whether consumption patterns followed the expected negative relationship between arthropod ingestion and body size as postulated in the Jarman-Bell and Kay models. We identified 12 consumed arthropod taxa, including insects (beetles, grasshoppers, ants, flies, caterpillars, praying mantises, and others), spiders and millipedes. Medium and large-bodied primates consumed a greater diversity (measured by Simpson’s diversity index) and richness of arthropods, but differed in terms of composition of taxa consumed. Cacajao, Sapajus and Cebus consumed proportionally more Orthoptera and Coleoptera compared to the other primate genera analyzed. We did not find significant correlations between richness and diversity of arthropods consumed and primate body mass. There was a slight tendency for the decrease in the relative content of arthropods in the diet with increased body mass in medium and large primates, which does not provide full support for the Jarman-Bell and Kay models. The study of arthropod consumption by arboreal primates in the wild remains challenging. Our study suggests that arthropods supply essential nutrients for frugivorous primates, and provides an alternative method to analyse faunal consumption patterns in primates.

“…Previous studies have shown that hooded capuchins in Paraguay can alter their diets in forests of differing ‘quality’ or levels of disturbance (Smith, 2021). These monkeys appear to require less space than other capuchin species (genera Cebus and Sapajus ) with small home ranges of 50–80 ha ( Sapajus nigritus : 5–465.3 ha [Di Bitetti, 2001; Izar et al., 2007; Rímoli, 2001]; Sapajus flavius : 270 ha [de Souza Lins & Ferreira, 2019]; Sapajus libidinosus : 345 ha [Presotto et al., 2018]; Sapajus apella : 320 ha [Gómez‐Posada et al., 2019]). In degraded Paraguayan BAAPA, hooded capuchins were found to preferentially select sleeping sites displaying characteristics of more mature forests such as taller trees with higher diameter at breast height, greater canopy connectivity and more main branches (Smith, Hayes, et al., 2018).…”

Modelling habitat suitability for a potential flagship species, the hooded capuchin, of the Paraguayan Upper Paraná Atlantic Forest

The hooded capuchin (Sapajus cay) is an adaptable, generalist primate species found throughout eastern Paraguay with preferences for the Paraguayan Upper Paraná Atlantic Forest (BAAPA). BAAPA is one of the world's most critically endangered terrestrial habitats with more than 90% of its original cover lost to industrial agriculture. Given its charismatic characteristics, the capuchin species is a candidate flagship species for this ecoregion; however, its habitat preferences in BAAPA degraded fragments are unknown. We develop a species distribution model using MAXENT to determine the remotely sensed microhabitat features associated with habitat suitability in forests that had experienced different levels of degradation. The model was fitted to presence‐only observations at two sites, Rancho Laguna Blanca and Nueva Gambach, to determine how hooded capuchin distribution is associated with remotely sensed habitat features in BAAPA fragments. Wetness (mean and standard deviation), a measure of soil moisture and canopy closure, was found to be the most important driver at both sites. The capuchins showed a preference for more mature forest, bamboo dominated forest and flooded forest (that has experienced little selective logging in the past). The capuchin was a forest obligate species and avoided crop fields. The monkeys were less likely to be found in degraded areas, even though they were still forested. As Paraguayan deforestation involves the creation of large crop fields separating BAAPA fragments, the probability that the hooded capuchin can move between those fragments is low. The hooded capuchin is a candidate flagship species for an agroforestry reforestation programme to reconnect BAAPA fragments. We propose that combining native tree corridors with shade grown yerba mate and slash pine plantations would create habitat for the capuchin and other wildlife while helping to alleviate poverty in the area and the pressure that this causes on the forests’ natural resources.

In ecological contexts natural selection might favor individuals with a larger body mass to monopolize resources; however, there is wide variation in body mass within populations and potential factors. In this study, we evaluated whether fruit production limits body mass in one group of Sapajus apella, its effects on behavior, and whether there is a relationship between social status and body mass. We recorded activity patterns using focal follows (20 min), body mass (using a modified Ohaus scale), and community wide fruit production estimates (from 60 fruit traps). Body mass remained relatively stable during periods of food scarcity, but in periods of abundance most individuals gained weight, as indicated by their relative growth rates (RGR). Subordinate subadults showed the highest RGR, as expected by their age. In periods of high fruit production activities as traveling, grooming, and playing were more frequent than during fruit scarcity, suggesting energy maximization and potential energetic constraints. We found differences in behavior within the group, as the alpha male was observed feeding more frequently (and for longer periods of time), was more aggressive (e.g., feeding trees), and received more grooming than other individuals. In addition, the alpha male was 60% heavier than the group's average body mass. Our study supports the hypothesis that body weight gain is related to fruit abundance and that body size is associated with social dominance; however, large individuals (both males and females) seem to incur in high metabolic or reproductive costs, as they do not gain much weight as smaller individuals.
