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…
Electrical Resistivity Surveying and Pseudo‐Three‐Dimensional Tomographic Imaging at Sitio Drago, Bocas del Toro, Panama
Results of electrical resistivity surveying and pseudo‐three‐dimensional tomographic imaging at the 15 ha Pre‐Hispanic archaeological site of Sitio Drago, Isla Colon, Bocas del Toro province, Panama are presented. The site was occupied between ad 690–1410 and represents the largest known nucleated settlement in the province. A low mound in the centre of the site was selected for intensive electrical surveying in order to locate buried archaeologi…
Copulation in free‐ranging black‐handed spider monkeys ( Ateles geoffroyi )
I report ad libitum data on 18 copulations involving free‐ranging black‐handed spider monkeys ( Ateles geoffroyi ) on Barro Colorado Island, Panama. All copulations were performed in a dorsoventral position, as is typically reported for this genus. Intromission often appeared difficult to achieve, possibly as a result of the large size of the glans penis in these animals. The average length from intromission to termination of thrusting exceeded 1…
Lethal intragroup aggression by adult male spider monkeys ( Ateles geoffroyi )
I report three cases of coalitionary aggression by adult male black‐handed spider monkeys ( Ateles geoffroyi ) against subadult males within their community on Barro Colorado Island (BCI), Panama. Two of these cases were followed by the disappearance and presumed death of the victim. Similar behavior was recently reported by Valero et al. [in press], who suggested that this behavior may be the result of intense male reproductive competition. Like…

Patterns of behavior across reproductive states of free‐ranging female black‐handed spider monkeys ( Ateles geoffroyi )
Reports on the behavior of spider monkeys (genus Ateles ) describe a suite of 5–6 behaviors that are indicative of an estrous female. This study presents hormonal data as an independent measure of reproductive state to determine if these behaviors are associated with any particular reproductive state or stage of the ovarian cycle. Fecal samples collected from 6 free‐ranging female black‐handed spider monkeys ( Ateles geoffroyi ) over the course o…
Female-Directed Aggression in Free-Ranging Ateles geoffroyi
Fecal analysis of ovarian cycles in female black‐handed spider monkeys ( Ateles geoffroyi )
An enzyme immunoassay (EIA) was applied to characterize the reproductive endocrinology of adult female black‐handed spider monkeys ( Ateles geoffroyi ). Analysis of paired urine and fecal samples, collected from two females housed at San Diego Zoo, confirmed that the EIAs employed provided quantitative measurements of ovarian sex steroid hormones. Fecal metabolite levels were significantly correlated with those in urine, confirming that feces are…
Fur rubbing behavior in free-ranging black-handed spider monkeys (Ateles geoffroyi) in Panama
Members of the population of black-handed spider monkeys (Ateles geoffroyi) on Barro Colorado Island, Panama, use the leaves of three Rutaceae species in a behavior that resembles fur rubbing in the white faced capuchin (Cebus capucinus). This behavior has not been reported from other sites where Ateles has been studied. During more than 1,200 hours of observation, 30 episodes of this behavior were recorded ad libitum. Adult males engage in this …
Craniometric variation in a population of mantled howler monkeys (Alouatta palliata): Evidence of size selection in females and growth in dentally mature males
A large body of work on monkey cranial metrics (involving conclusions about interspecific variation, sexual dimorphism, and ontogeny) depends on the assumptions that growth effectively ceases with dental maturity and that intraspecific variation is negligible. We test these assumptions by examining variation in 39 measurements of 166 dentally mature Alouatta palliata skulls from animals found dead on Barro Colorado Island (BCI), Panama. We also i…
