Chimpanzees of the Lakeshore
Chimpanzees are humanity's closest living relations and are of enduring interest to a range of sciences, from anthropology to zoology. In the West, many know of the pioneering work of Jane Goodall, whose studies of these apes at Gombe in Tanzania are justly famous. Less well-known, but equally important, are the studies carried out by Toshisada Nishida on the eastern shore of Lake Tanganyika. Comparison between the two sites yields both notable similarities and startling contrasts. Nishida has written a comprehensive synthesis of his work on the behaviour and ecology of the chimpanzees of the Mahale Mountains. With topics ranging from individual development to population-specific behavioural patterns, it reveals the complexity of social life, from male struggles for dominant status to female travails in raising offspring. Richly illustrated, the author blends anecdotes with powerful data to explore the fascinating world of the chimpanzees of the lakeshore.

Chimpanzees
Recollecting the what-where-when of an episode, or episodic-like memory, has been established in corvids and rodents. In humans, a linkage between remembering the past and imagining the future has been recognised. While chimpanzees can plan for the future, their episodic-like memory has hardly been investigated. We tested chimpanzees (Pan troglodytes) with an adapted food-caching paradigm. They observed the baiting of two locations amongst four and chose one after a given delay (15 min, 1 h or 5 h). We used two combinations of food types, a preferred and a less preferred food that disappeared at different rates. The subjects had to base their choices on the time elapsed since baiting, and on their memory of which food was where. They could recover either their preferred food or the one that remained present. All animals failed to obtain the preferred or present foods above chance levels. They were like-wise unsuccessful at choosing baited cups above chance levels. The subjects, thus, failed to use any feature of the baiting events to guide their choices. Nonetheless, their choices were not random, but the result of a developed location-based association strategy. Choices in the second half of the study correlated with the rewards obtained at each location in the first half of the study, independent from the choices made for each location in the first half of the study. This simple location-based strategy yielded a fair amount of food. The animals' failure to remember the what-where-when in the presented set-up may be due to the complexity of the task, rather than an inability to form episodic-like memories, as they even failed to remember what was where after 15 minutes.

Chimpanzee (Pan troglodytes) Winter DietsLIU LonghaiJIANG ZhiLOU YiHUANG Shufang
2017年冬季, 为检验杭州动物园黑猩猩冬季饲料是否在行为和营养上满足需求, 粗略计算黑猩猩冬季饲料营养成分, 与日本、阿根廷、上海野生动物园、国内动物园的日粮营养成分对比, 同时参照中国营养学会推荐的人类膳食营养平衡标准和AZA黑猩猩饲养指南, 结合杭州动物园黑猩猩实际生长发育情况, 评估黑猩猩冬季饲料。结果显示, 杭州动物园冬季黑猩猩饲料在营养成分上, 总能量 (105—159 MJ) , 高于黑猩猩维持能量 (711—8372 MJ) , 蛋白质 (79—119 g) 、脂肪 (55—83 g) 、碳水化合物 (401—602 g) 、微量元素总含量符合人的营养素参考摄入量和AZA黑猩猩饲养指南；在饲料种类上, 蔬菜、水果、奶类的比例与已知5个动物园饲料总量均值之间没有显著差异 (P>005) , 水果总量高于推荐量, 无植物类食物供应。杭州动物在黑猩猩冬季饲料种类和营养成分上可以满足基本需求, 但仍需改进, 建议在满足营养需求的基础上, 通过减少或更换水果、增加植物类饲料、增加干粮纤维比例等增加日粮的纤维含量。

The new chimpanzee : a twenty-first-century portrait of our closest kin
The history of research into the lives of wild chimpanzees now spans more than a half-century since Jane Goodall began it all. The past 20 years have seen tremendous advances in our understanding of our closest kin. These include revelations about our very similar genomes, but also many new discoveries about social behavior and ecology. New cultural traditions and forms of tool use, new evidence for the causes of violence, new evidence of patterns of hunting and meat-eating, and much more. Chimpanzees are new and different apes than they were at the close of the last century. The New Chimpanzee synthesizes the findings of the past 20 years and offers new insights and interpretations of what researchers have learned. The New Chimpanzee draws from results of the 7 longest term (25-55 years) research projects from which we've learned the most about the species, augmented by other shorter field projects conducted in recent years, including my own.-- Provided by publisher
