Lemur redux: Something old, something new, and reader blue. Review of Lemur Social Systems and their Ecological Basis, edited by P.M. Kappeler, J.U. Ganzhorn, and Peter Jörg

This book contains 15 papers presented at a symposium on lemur behavioral ecology at the XIV Congress of the IPS in Strasbourg, France in 1992, plus two papers from work completed after the symposium. The editors state that it was their goal to update and review general knowledge of lemurs because they felt that lemur behavior and ecology has been given more attention in the past decade and that information on newly studied populations and newly discovered species should be made available. They succeeded in some of these goals. The 17 papers consist of three review papers (predation by Goodman et al.; sexual dimorphism by Kappeler; infanticide by van Schaik and Kappeler), three captive studies (Macedonia; Pereira; White et al.) four semi-free ranging studies: two of provisioned ringtailed lemurs at Berenty (Jolly et al.; Rasamimanana and Rafidinarivo) and two of translocated aye-aye and black-and-white ruffed lemurs on Nosy Mangabe (Sterling; Morland); and seven field studies of wild lemurs (Colquhoun; Rigamonti; Sauther and Sussman; Sauther; Ganzhorn; Overdorff, Meyers and Wright). In addition to the three review papers, five of the papers are on Lemur catta (Jolly et al.; Sauther and Sussman; Rasamimanana and Rafidinarivo; Sauther; Pereira), one on Lemur catta and Varecia variegata variegata (Macedonia), two on Varecia uariegata variegata (White et al.; Morland), one on Daubentonia madugascariensis (Sterling), one on Eulemur macaco macaco (Colquhoun), one on Varecia uariegata rubra (Rigamonti), one on Lepilemur (Ganzhorn), one on Eulemur fulvus rufus and Eulemur rubriuenter (Overdorff), and one on Propithecus diadema edwardsi and Propithecus tattersalli (Meyers and Wright). Study site locations, in addition to those already mentioned at Berenty (two) and Nosy Mangabe (two) were two at Beza Mahafaly (Sauther; Sauther and Sussman), one at Ranomafana (Overdorff), one at Ranomafana and Daraina (Meyers & Wright), one at Ambato Massif (Colquhoun), one at Masoala peninsula (Rigamonti), and one at the four different sites of Analamazaotra, Ampijoroa, Ankarana, and Morondava (Ganzhorn). Six of the papers were either done at the Duke University Primate Center (DUPC) or data from DUPC records were used (White et al.; Macedonia; Meyers and Wright; Pereira; Kappeler; van Schaik and Kappeler) . The book is almost free of spelling errors (only two were noted) and is pleasingly presented. Putting the references at the end of each paper is much preferred to placing them at the end of the book. The French summaries of each paper at the end of the book are a nice touch. This is both a satisfying and frustrating book to read. It is satisfying in the sense that it has been 20 years since lemurs have been the organizing focus of an international conference, new information is presented on species for which there
