For permission to conduct research in Amboseli National Park over many years we thank the National Research Council, the Kenya Wildlife Service and the Wardens of Amboseli National Park.

Our many colleagues and collaborators have our deepest thanks for their commitment, support and friendship. We are grateful for the opportunity to work with these individuals and to learn from their experiences.

Many thanks go to our Board members: Coco Hall and Nidhi Singh.

In addition, we thank our many supporters whose kind words and financial and in-kind assistance keep us moving forward.
