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…
Synchronization of weaning time with peak fruit availability in squirrel monkeys ( Saimiri collinsi ) living in Amazonian Brazil
Many mammals coincide their reproductive activities with factors such as ambient temperature, rainfall, and food availability. In primates that invest immediate food intake into reproduction, the periods of maximum fruit production often coincide with the peak of lactation (to maximize maternal survival) or the occurrence of weaning (to maximize infant survival). This study investigates the relationship between reproductive periods and the availa…
Reproductive status affects the feeding ecology and social association patterns of female squirrel monkeys ( Saimiri collinsi ) in an Amazonian rainforest
When making foraging decisions, female primates may follow specific behavioral strategies that reflect their reproductive state. Lactation is considered the most energetically costly phase for females, but we argue that gestation is also energetically expensive for squirrel monkeys. In this study, we examined whether female squirrel monkeys (a seasonally breeding primate) in different reproductive phases showed significant differences in their fo…
A novel method for capturing and monitoring a small neotropical primate, the squirrel monkey ( Saimiri collinsi )
Squirrel monkeys (genus Saimiri) are agile, arboreal primates that are seldom captured in the wild due to their small body size (<1 kg) and large, non-cohesive social groups (40-50 individuals). However, long-term studies on these primates often require captures and permanent identification of individuals, in order to monitor their behavior and health. Here we report on a novel trapping method successfully used to capture Saimiri collinsi, in Eas…
Is Fatter Sexier? Reproductive Strategies of Male Squirrel Monkeys (Saimiri sciureus)
Integration of field and captive studies for understanding the behavioral ecology of the squirrel monkey ( Saimiri sp.)
Captive and field studies both provide valuable and complementary information that lead to a better understanding of a species' behavioral ecology. Here, we review studies from wild, captive, and semi‐free ranging populations of squirrel monkeys ( Saimiri sp.), in order to (a) provide a more current (1985–2010) review of Saimiri behavioral ecology and (b) illustrate that integrating data collected in a variety of settings is an effective approach…
Seasonal Effects on Play Behavior in Immature Saimiri sciureus in Eastern Amazonia
Responses of squirrel monkeys to seasonal changes in food availability in an eastern Amazonian forest
Tropical forests are characterized by marked temporal and spatial variation in productivity, and many primates face foraging problems associated with seasonal shifts in fruit availability. In this study, I examined seasonal changes in diet and foraging behaviors of two groups of squirrel monkeys ( Saimiri sciureus ), studied for 12 months in Eastern Brazilian Amazonia, an area characterized by seasonal rainfall. Squirrel monkeys were primarily in…
Age and seasonal effects on predator‐sensitive foraging in squirrel monkeys ( Saimiri sciureus )
A field experiment was conducted to examine the effect of perceived predation risk on the use of foraging areas by juvenile and adult primates under different conditions of local food abundance. Wild squirrel monkeys, Saimiri sciureus , were observed in an experiment conducted during the dry and the wet seasons at a site in Eastern Amazonia, Brazil. Animals were presented with feeding platforms that differed in food quantity and exposure to aeria…
