Variation in Maternal Effort, Activity Budgets, and Feeding Behavior in Wild Saddleback Tamarins ( Leontocebus weddelli ) in Northwestern Bolivia
Among primates, maternal infant care may vary in response to several factors including litter size, reproductive history, and health status. In cooperative breeders, maternal investment may also depend on the amount of help their group mates (or allomothers) provide. We studied infant care and activity in four wild groups of saddleback tamarins ( Leontocebus weddelli ) and collected hair and fecal samples from which we extracted genomic DNA to es…
Variable infant care contributions in cooperatively breeding groups of wild saddleback tamarins
Among non‐human primates, alloparental infant care is most extensive in callitrichines, and is thought to be particularly costly for tamarins whose helpers may suffer increased energy expenditure, weight loss, and reduced feeding time and mobility. The costs and benefits of infant care likely vary among group members yet very few wild studies have investigated variable infant care contributions. We studied infant care over an 8‐month period in fo…
Nutritional ecology of wild Bornean orangutans ( Pongo pygmaeus wurmbii ) in a peat swamp habitat: Effects of age, sex, and season
The spatial and temporal variation in food abundance has strong effects on wildlife feeding and nutrition. This variation is exemplified by the peatland forests of Central Kalimantan, which are characterized by unpredictable fruiting fluctuations, relatively low levels of fruit availability, and low fruit periods (<3% of trees fruiting) that can last nearly a year. Challenged by these environments, large, arboreal frugivores like orangutans must …
Mother's little helpers: What we know (and don't know) about cooperative infant care in callitrichines
Since Darwin ( ), scientists have been puzzled by how behaviors that impose fitness costs on helpers while benefiting their competitors could evolve through natural selection. Hamilton's ( ) theory of inclusive fitness provided an explanation by showing how cooperative behaviors could be adaptive if directed at closely related kin. Recent studies, however, have begun to question whether kin selection is sufficient to explain cooperative behavior …
Are simakobu ( Simias concolor ) loud calls energetically costly signals
OBJECTIVES: Male vocal displays play an important role in sexual selection in many species. If there are costs or constraints, calls may convey honest information about the caller. We studied the loud calls of male simakobu (Simias concolor), a sexually dimorphic primate that resides in one-male groups, on Siberut Island, Indonesia. MATERIALS AND METHODS: We combined behavioral and ecological data with acoustic analysis to determine the influence…
Demography of Simakobu ( Simias concolor ) and the Impact of Human Disturbance
Asian colobines typically live in small one‐male groups ( OMG s) averaging five adult females, but S imias concolor (simakobu or pig‐tailed langur) is considered an exception because mostly adult male–female pairs have been reported. However, based on their phylogenetic position and marked sexual dimorphism, simakobu are also expected to form OMG s with multiple females. The preponderance of small groups could be the result of human disturbance (…
