Aloha mai kākou! Welcome to the joint meeting of our two esteemed societies! This gathering marks the 84th annual meeting of the American Malacological Society (AMS) and the 51st annual meeting of the Western Society of Malacologists (WSM). This is the second AMS (Dr. E. Alison Kay was president in 1995) and first WSM meeting in Hawaii. We are thrilled to celebrate innovative molluscan research (and researchers) and have an incredible program planned with 160 attendees (42 of which are students ranging from high school to doctoral) and over 130 contributions (talks and posters). Steeped in the deep cultural traditions of the Hawaiian people, we are gathering on the island of Oahu (The Gathering Place in Hawaiian) to “talk story” about all things malacological. Presentations and the discussions following are framed within the context of this year’s theme, “Building Capacity and Developing Solutions for the Future” and five symposia have been organized around this theme: 1) Celebrating Women in Malacology (convened by Rebecca F. Johnson, Norine W. Yeung and Ellen E. Strong): dedicating this symposium to the outstanding research and experiences of women in all of the many fields that make up malacology 2) The Revitalization of Natural History Museums (convened by Rebecca F. Johnson and Paul Callomon): highlighting research, digitization efforts and educational outreach developed to engage society 3) Amateur Malacologists and Citizen Scientists (convened by Rebecca F. Johnson and Manuel Caballer Gutierrez): recognizing the significant role of amateurs in modern malacology and presenting their citizen science activities 4) Stemming the Tide of Extinction (convened by Kenneth A. Hayes and Diarmaid Ó Foighil): sharing the latest research on Pacific island land snail research and conservation with a special session at the end for researchers and conservation managers to develop a consortium for determining short- and long-term research goals and conservation management priorities for this fauna 5) Impacts of invasive species (convened by Kenneth A. Hayes with support from John Slapcinsky and David G. Robinson): providing up-to-date information regarding the systematics, distribution, and negative impacts of invasive molluscs with a 6-hour taxonomic workshop on the first day of the conference providing training in surveys, identification, and current and potential invasive land snail species with specific emphasis on Hawaii and the Pacific Islands. In addition to these symposia, we have contributed sessions that include: contemporary and historical diversity; ecology; systematics, and evolution; anatomy and morphology; and diversity and delimitation. For the Wednesday lunch session, we have Simon L. Malcomber from the National Science foundation presenting updates and insights, and Thursday, a student-mentor meet-greet-eat lunch session. The conference is bookended by a welcome reception at the Waikiki Aquarium and a banquet dinner hosted by the Bernice Pauahi Bishop Museum. In between, we hope the participants will enjoy the hospitality of the islands while meeting to explore and discuss the latest discoveries in malacology, socialize with colleagues, and collaborate to develop strategies for conserving molluscan diversity and building research capacity. As part of our societies’ tradition, the conference will also include an auction to support student research, poster sessions, and social networking events. Please come to the auction and, bid on American Malacological Society 2018 Program and Abstracts 2 some great items to support them even more! The final day of the conference is reserved for field trips and exploration of the island, and will include opportunities to visit snorkeling beaches, land snail conservation facilities, and natural area reserves where visitors can see the few remaining endemic snail species. We would like to give “plenny mahalos” to the organizing committee (especially Ellen E. Strong, Kenneth A. Hayes, John Slapcinsky, Jessica Goodheart), BPBM snailers (Kelli DeLeon, Rachel Sommer, Ryan Kong, Elaine Mahoney, Jaynee Kim, Tricia Goulding, Kim Lactaoen, Connor Kalahiki, Lily Evans, Emily Norman, Rachel Sommer, Jamie Tanino, Kelli DeLeon, James Kwon, Regina Kawamoto) and support team (Janis Matsunaga, Lynette Williams). A super special mahalo to Irene and Ricky Yeung for watching over and helping train our junior snailer David Yeung Ching Hayes while mom and dad worked. We are looking forward to spending time with all of you and hosting you and your families on the island we call home. Enjoy the meeting! Finally, here are a couple of our personal thoughts regarding being president of AMS and WSM: Rebecca: I gave my first professional talk at a WSM meeting in San Diego in 1996, as recent college graduate. Over the years, I have found a great community of colleagues and friends at WSM and AMS meetings. I have never forgotten how welcomed and included I felt at that first meeting and every meeting since. Please go out of your way to welcome the many students (and first time attendees) here this week. Thanks to Ángel Valdés, Jann Vendetti, Terry Gosliner, Pat Krug and all the WSM board members past and present for entrusting me with this job and honor. And thanks to Nori for proposing we host a joint meeting in her backyard. Nori and her team have worked tirelessly, made it look easy, and smiled through it all. Thanks, Nori! Nori: I did not start “snailing” seriously until 2009 and did not even think that I would be hosting an AMS meeting. So here we are and hope we did the Society proud with this conference. Many thanks to Ken Hayes, Ellen Strong, Jeanne Serb, and John Slapcinsky for convincing me that this would be a fantastic idea and that they would help immensely in the organization of it. No, there are no hints of sarcasm at all. Many apologies to Ken and Rebecca for all the last-minute requests and their patience in coming through with it all! Lastly, supah plenny mahalo to my BPBM snailers… da best! Mahalo piha, Norine W. Yeung President, American Society of Malacologists, 2018 Rebecca F. Johnson President, Western Society of Malacologists, 2018 American Malacological Society 2018 Program and Abstracts 3 Mahalo to our Sponsors Mahalo nui loa to all the organizations, people, and businesses that contributed time, funding, resources, and supplies to help keep the costs down for this year’s conference. Without such contributions from our Hawaii Ohana it would not have been possible to bring you all to the fabulous venue and have our events at these major attractions. Much appreciation to the Bishop Museum for waiving event and rental fees, co-hosting the meeting website (Nick Griffith), assisting with fiscal administration (Tracie Mackenzie), advising event activities (Courtney Chow), organizing the banquet, and providing a fantastic venue to close the conference (Amber Bixel, Loren Doctolero) The Waikiki Aquarium is hosting our opening reception and generously helped keep our facility costs low. Irifune (Toshi and Kazuyo Ishizawa and Cindi Lewis) graciously came out of retirement to provide fabulous local cuisine for the reception. Sheila Conant, David McCauley, Carl Christensen, Patrick Kirch, DLNR SEPP provided generous donations and funding support to the Pacific Island Land Snail Symposium, which helped bring researchers and support students at this year’s conference. Thank you to Betsy Gagne for donating funds in memory of E. Alison Kay and Wayne Gagne, Regina Kawamoto, the Pacific Biosciences Research Center (special thanks to Jan Tamanaha, Margaret McFall-Ngai and Thomas Kwock) all provided valuable conference support. Thank you to Jared, Mary, and Jaynee Kim for sponsoring the Mt Kaala field trip. The Hawaii Malacological Society helped sponsor the conference, student awards, and registration support. Beverages and food were donated by the Waikiki Brewing Company, Maui Brewing Company, Hawaiian Chip Company and Bubbies Homemade Ice Cream & Desserts for various conference events.
