Fermented food consumption in wild nonhuman primates and its ecological drivers
OBJECTIVES: Although fermented food use is ubiquitous in humans, the ecological and evolutionary factors contributing to its emergence are unclear. Here we investigated the ecological contexts surrounding the consumption of fruits in the late stages of fermentation by wild primates to provide insight into its adaptive function. We hypothesized that climate, socioecological traits, and habitat patch size would influence the occurrence of this beha…
Successful adoption of an orphan infant in a wild group of brown howler monkeys
Howler monkey tolerance to habitat shrinking
Habitat loss and fragmentation are major threats to the conservation of nonhuman primates. Given that species differ in their responses to fragmented landscapes, identifying the factors that enable them to cope with altered environments or that cause their extirpation is critical to design conservation management strategies. Howler monkeys ( Alouatta spp.) are good models for studying the strategies of tolerant arboreal taxa and how they cope wit…
Surviving in the urban–rural interface
Wild primates that live in urban areas face extreme threats that are less frequent in nonurban fragments, such as the presence of dangerous matrix elements (e.g., roads, power lines, buildings, and a high density of domestic dogs near food patches), that could influence their movements, feeding behavior, and survival. However, the scarcity of studies addressing this issue hinders our understanding of the behavioral adjustments that favor the surv…
Fruit availability drives the distribution of a folivorous–frugivorous primate within a large forest remnant
Understanding the ecological factors that influence the presence, abundance, and distribution of species within their habitats is critical for ensuring their long-term conservation. In the case of primary consumers, such as most primates, the availability and richness of plant foods are considered key drivers of population density at these variables influence the spatial distribution of social units within a finer, habitat patch level scale. We t…
Crop Feeding by Brown Howlers (Alouatta guariba clamitans) in Forest Fragments
Parturition and potential infanticide in free-ranging Alouatta guariba clamitans
Primate extirpation from rainforest fragments does not appear to influence seedling recruitment
Primates are important seed dispersers, especially of large-seeded tree species, but the impact that these animals have on seedling recruitment is unclear. Evidence suggests that forest regeneration might be disrupted in forest fragments in which primates were extirpated. We tested this hypothesis by assessing seedling recruitment in 3 forest fragments occupied (OF) by primates, 3 fragments unoccupied (UF) by primates, and 3 areas within a contin…
Dietary Flexibility of the Brown Howler Monkey Throughout Its Geographic Distribution
Habitat loss and fragmentation constrain the survival of most forest‐living mammals, particularly strictly arboreal primates. Because fragment size directly affects food availability, primate survival in small fragments may depend on dietary flexibility. Here, we review the literature on the diet of 29 wild groups of A louatta guariba clamitans inhabiting forest fragments in B razil and A rgentina. We identify general feeding patterns and analyze…
Influence of climatic variables, forest type, and condition on activity patterns of geoffroyi's spider monkeys throughout Mesoamerica
Understanding how species cope with variations in climatic conditions, forest types and habitat amount is a fundamental challenge for ecologists and conservation biologists. We used data from 18 communities of Mesoamerican spider monkeys ( Ateles geoffroyi ) throughout their range to determine whether their activity patterns are affected by climatic variables (temperature and rainfall), forest types (seasonal and nonseasonal forests), and forest …
Effectiveness of Spider Monkeys (Ateles geoffroyi vellerosus) as Seed Dispersers in Continuous and Fragmented Rain Forests in Southern Mexico
Seasonal Differences in Activity Patterns of Geoffroyi ́s Spider Monkeys (Ateles geoffroyi) Living in Continuous and Fragmented Forests in Southern Mexico
Diet of spider monkeys ( Ateles geoffroyi ) in Mesoamerica
Here we review all published articles and book chapters, as well as unpublished theses and data of Ateles geoffroyi diet to (1) summarize the literature; (2) synthesize general feeding patterns; (3) document plant taxonomic similarity in diet across study sites; and (4) suggest directions for future research and conservation priorities. We found 22 samples from five countries: Mexico, Guatemala, El Salvador, Costa Rica and Panama. Tropical wet fo…
