摘要:
AbstractDifferences in the social organization and dental morphology ofPan paniscus(bonobos) andPan troglodytes(chimpanzees) have been related to differences in the spatiotemporal availability of food and its exploitation. The presence of abundant terrestrial herbaceous vegetation (THV) in the bonobo's habitat and the apparent greater reliance on herbs for food has been used to explain differences in party size and, by extension, social organization. Using fecal analysis, we assess quantitatively the amount of herbaceous foods consumed byPan paniscusin the Lomako Forest, Zaire, compared to similar data forPan troglodytesin the Kibale Forest, Uganda. We examine this data in the context of spatiotemporal patterns of availability of herbaceous foods and fruit, as well as their nutritional content. The results support the suggestion that bonobos consume more herbaceous food than do the Kibale chimpanzees and that these foods are more prevalent in the bonobo's habitat than in the Kibale Forest. However, temporal changes in fruit availability and herb consumption, along with nutritional analyses, suggest that chimpanzees consume herbs as a fallback source of carbohydrates, whereas bonobos consume herbs as a source of protein regardless of season or fruit abundance. Available data suggest that party size while feeding on terrestrial herbs is restricted at both sites, but a determination of the relative strength of this constraint is not possible at this time. Difficulties in methods used for data collection are discussed and areas where more information is needed are highlighted. © 1994 Wiley‐Liss, I
