Logistical and research assistance in Kenya
For assistance and cooperation in Kenya, we are very grateful to the Kenya Wildlife Service (KWS), University of Nairobi, Institute of Primate Research (IPR), National Museums of Kenya, National Environment Management Authority, and National Commission for Science, Technology, and Innovation (NACOSTI). We also thank members of the Amboseli-Longido pastoralist communities, Tortilis Camp, Ker & Downey Safaris, Serena Lodge, Air Kenya, and Safarilink. Without their support and presence in Amboseli, we would not be able to carry out the work. Finally, Vera Somen, Tim Wango, and Vivian Oudo have provided untiring assistance in Nairobi with everything from official permits to storing personal belongings; Tim and Vivian have also played a critical role in managing, preparing, and shipping biological samples for the research.

Particular thanks go to the Amboseli Baboon Project long-term field team, which consists of Raphael S. Mututua, Serah N. Sayialel, J. Kinyua Warutere, and Long'ida Siodi. We also thank Amy Samuels and Stuart Altmann for their many contributions not only to data collection but to protocol design and project infrastructure.
