“…Blackand-white colobus also rely to a great extent on Pentaclethera macrophylla seeds. [99][100][101][102][103] These seeds are housed in large woody pods that require extended processing times and are accompanied by long bouts of sitting (Fig. B2).…”

“…The frequent sitting postures that characterize black-and-white colobus are therefore as much a function of highly prized and labor intensive fruits as they are related to folivory. [101][102][103][104] Most other arboreal monkeys with large frugivorous components sit less and have positional repertoires that include elevated frequencies of standing and other ''upright'' postures. Such positions facilitate rapid, efficient movement to the next feeding source.…”

Socioecology, predation, and cognition in a community of West African monkeys

The Ivory Coast's Taï Forest is home to a diverse primate fauna, including eight monkey species that interact daily with the environment, each other, and a web of predators. These interactions have led to an array of adaptations, some of which conform to theoretical expectations, and others are at odds with current behavioral ecology models. In this paper, we draw on fifteen years of observations to examine two central issues. First, how do broad trends in diet and resource distribution influence group size and levels of sociality? Second, what mechanisms are used to counter pressures exerted by the predator community? The general picture that emerges is that while the pressure exerted by predators at Taï has led to a host of behavioral and cognitive adaptations, it is food preferences and foraging habits, not predation pressure, that are the main determinants, not only of group size, but also its direct consequences ‐ mating systems and sociality levels.

“…Unique trophic specialists can also have elevated rates of morphological evolution [84]. In this case, folivory may be an evolutionary 'dead-end' for colobines owing to foliage being a much less nutritious food than other vegetative items [85]. Primates with low-quality diets offset energetic deficiencies with trade-offs such as longer rest periods [86] and larger body size [87].…”

The role of ecological opportunity in shaping disparate diversification trajectories in a bicontinental primate radiation

Exceptional species and phenotypic diversity commonly are attributed to ecological opportunity (EO). The conventional EO model predicts that rates of lineage diversification and phenotypic evolution are elevated early in a radiation only to decline later in response to niche availability. Foregut fermentation is hypothesized to be a key innovation that allowed colobine monkeys (subfamily Colobinae), the only primates with this trait, to successfully colonize folivore adaptive zones unavailable to other herbivorous species. Therefore, diversification rates also are expected to be strongly linked with the evolution of traits related to folivory in these monkeys. Using dated molecular phylogenies and a dataset of feeding morphology, I test predictions of the EO model to evaluate the role of EO conferred by foregut fermentation in shaping the African and Asian colobine radiations. Findings from diversification methods coupled with colobine biogeographic history provide compelling evidence that decreasing availability of new adaptive zones during colonization of Asia together with constraints presented by dietary specialization underlie temporal changes in diversification in the Asian but not African clade. Additionally, departures from the EO model likely reflect iterative diversification events in Asia.

“…Specifically, if leaves are of poor quality and fruiting resources are scarce in the more speciose eastern humid forests, then large-bodied indriids (Indri indri, Propithecus diadema diadema, and P. d. edwardsi) may be at an advantage in interspecific competition for scarce fruit resources (Clutton-Brock and Harvey, 1983). Fruit resources are particularly relevant to the energy hypothesis because they contain more easily extractable energy, in the form of sugars, than leaves do (Dasilva, 1992;Milton, 1999;Wasserman and Chapman, 2003).…”
