Bonjour I recently contributed a chapter in a book on Sexual Segregation, in which I examine the extent and the possible causes of sexual segregation in odontocetes. The book: Sexual Segregation in Vertebrates: Ecology of the Two Sexes Edited by Kathreen Ruckstuhl and Peter Neuhaus Cambridge University Press Published January 2006 | 500 pages | 247 x 174 mm Overview: An understanding of sexual segregation is important in the explanation of life history and social preference, population dynamics and the conservation of rare species. This book explores the reasons why this behaviour has evolved and what factors contribute to it. Chapters provide a synthesis on many different vertebrate groups This is the first synthesis, to our knowledge, on sexual segregation Highlights important implications for conservation Chapter 16 For those who are interested, I can send a PDF of my chapter (16 Sociality and ecology of the odontocetes, Robert Michaud) Robert Michaud Scientific director Groupe de recherche et d'education sur les mammiferes marins Tadoussac, Quebec, CANADA rmichaud@gremm.org ****************** For those who are interested to read more, here is the table of content of the book Part I Overview 1.
