For upper-level and/or graduate level Primatology or Biological Anthropology courses.
Socioecology of Adult Female Patas Monkeys and Vervet in Kenya, East Africa provides students with a glimpse into a research project from start to finish. It discusses basic issues of studying primates and explores one of the major theories that has defined primatology for several decades. This text not only contributes detail on primate behavior, but also on the ecological variables that influence primate behavior. These are often difficult to measure, but the unique environment at the study site enabled the author to address questions that are much more difficult to answer elsewhere.
