The Department of Anthropology is excited to be hosting you this year at Boise State University. Following the format from the last few meetings, the conference begins with a plenary lecture on Wednesday afternoon and culminates with the Keynote Lecture on Saturday night. There are no Sunday sessions. There is a pre-conference, “Connecting Minds in Social Neuroendocrinology and Evolution” on Wednesday morning, and the 6th ISHE Summer Institute immediately follows HBES from Sunday to Tuesday. To highlight the work of the best young HBES researchers, there are conference-wide New Investigator and Post-Doctoral Competition sessions on Friday afternoon. To support student mentorship, we are continuing the Graduate Student Luncheon, this year with five thematic sessions, including one for prospective graduate students. We received more than 150 sign-ups, demonstrating growing demand for mentorship. The Graduate Student Luncheon is being sponsored by the Dan Montgomery Northwest Evolution, Ecology, and Human Behavior (NWEEHB) Symposium Fund at the Boise State University Foundation. Dan set up an endowment for NWEEHB, our regional conference four years ago. Our NWEEHB symposium will resume in fall, 2018. We hope you can get out and enjoy beautiful Boise while you are here. To that end, we scheduled the Wednesday Reception at the Boise Train Depot just south of campus on South Capital Blvd overlooking downtown Boise, and the BBQ on Friday night at Payette Brewery across and down the Boise River on the greenbelt approximately 1 mile by foot. The third annual gathering of the Women of HBES (WoHBES) will also occur on Friday evening immediately following the last afternoon session until 7:15pm (just before the start of the BBQ), also at Payette Brewery. Throughout the conference, the Boise River Café (BRC) will be open for breakfast and lunch (including Sunday morning). The BRC is a cafeteria style, all-you-can-eat venue located in the first floor of the Student Union Building (the conference venue). Costs are $7.18 for breakfast and $9.60 for lunch (see map of the Student Union Building on page 17). There are many people who helped to make this conference happen. We’d like to call out a few (see the next page for a full list). We are grateful to the Poster, New Investigator, and Post-Doctoral Award judges, who through their service are helping to highlight the accomplishments of young researchers. We thank the mentors facilitating the Graduate Student Luncheon sessions, helping a new generation of researchers with important guidance. We’d like to give special thanks to our Graduate Assistant, Erica Jaeger, for helping to organize the event, and to Kathryn Demps who led the organizing committee until early March. We are grateful for all her early efforts. We thank our multitude of Student Volunteers who will be recognizable by their distinctive name tags. We received helpful advice and support from HBES members and officers. In particular, we’d like to thank Elizabeth Cashdan, Catherine Salmon, Lisa DeBruine, and Robert Kurzban for their help. And for advice from past meetings, we thank Laura Dane and Karthik Panchanathan. Many people here at Boise State University helped us with the organization of this meeting. In particular, we’d like to thank Faith Brigham, Administrative Assistant in the Department of Anthropology, Emma Ballantyne from Conference Services, Mishae Fuselier and Lindsey Castle from Catering Services, and Vera Frolova in the Summer Housing Office. And, we would like to thank our sponsors, in particular HBES, Dan Montgomery, Mark Rudin (Vice-President for Research and Economic Development at Boise State University), the journal Politics and Life Sciences, and Nature Human Behavior. We hope you enjoy the conference, and find it as enjoyable as intellectually stimulating. If you have any questions or difficulties, please contact members of the Host Committee or Student Volunteers. Kristin Snopkowski and John Ziker Conference Organizers, on behalf of the HBES Host and
