Summarizes the research on lemurs, often called the most primitive primates, over the past decade, emphasizing the only recently begun investigations into their behavioral ecology and evolutionary biology. Another species has even been identified since the last major conference on lemurs, in 1972. Home range and diet, male transfer in captives, the relations of female's feeding behavior to their physiological state, food availability and seasonal reproduction, and sexual selection, are among the topics. The 17 papers are from a symposium at the Congress of the International Primatological Society in Strasbourg, France, August 1992. Annotation c. by Book News, Inc., Portland, Or.
