摘要:
Natural food plants of partly provisioned groups of Macaca thibetana included about 196 species belonging to 135 genera and 72 families. The macaques consumed mainly bamboo shoots and fruits for about 2 months in autumn, whereas they relied on active or passive provisions from visitors, a variety of structural parts of plants and a small amount of invertebrates in late spring and summer and ate mainly mature leaves and bark for the rest of the year. About half of the species eaten came from the dense herb and shrub layers. This forest-dwelling species shows a distinctive feeding and foraging pattern in comparison with other macaques, explaining why M. thibetana has the largest body weight of all macaques.

摘要:
Ina survey of institutions holding cotton-top tamarins (Saguinus oedipus), we found 23 cases of potential non-monogamy. Nine had been deliberately set up as non-monogamous units; 14 arose spontaneously. Some general trends appeared: polyandrous groups were more likely to be stable than those with more than one potentially breeding female, and no more than one female per group successfully reared offspring at one time. Polyandry may therefore be the most viable alternative to monogamy, as recent reassessments of callitrichid mating systems have suggested.

摘要:
Soil-scratching behaviour by western lowland gorillas (Gorilla gorilla gorilla) was recognized in a field study in the Ndoki forest of northern Congo. The purpose of this behaviour was probably insect eating although the harvest of insects was likely to be relatively poor. The seasonal variation in the appearance of insects found in faecal samples coincided with the frequency of soil-scratching traces. Soil-scratching behaviour was considered not to make a large nutritional contribution for gorillas.
