AMERICAN ASSOCIATION OF ZOO VETERINARIANS “Dedicated to wildlife health and conservation” 581705 White Oak Road Yulee, Florida, 32097 904-225-3275 Fax 904-225-3289 Dear Friends and Colleagues, Welcome to our first-ever virtual AAZV Annual Conference! My deepest thanks to the AAZV Scientific Program Committee (SPC) and our other standing Committees for the work they have done to bring us to this point. AAZV is truly a volunteer organization. Members, just like you, continually step up to support the broader membership and organization. These members have worked consistently and diligently throughout the past year to keep AAZV moving forward, particularly impressive over the last 6 months as the COVID-19 pandemic took hold. A special “shout out” to the SPC. These incredible AAZV members planned our regular conference and then rapidly pivoted and did it all again as they moved the meeting to a virtual platform. Additional thanks to the Executive Director’s office for their tireless work and guidance as the Executive Committee grappled with the broader implications of the pandemic for the organization and supported the move to a virtual conference. The impacts of this pandemic continue to unfold. As a group, zoological and wildlife veterinarians are likely better positioned than most others to intellectually understand the scientific aspects of an emerging infectious disease, and a pandemic. That knowledge can be a source of strength and hope, it can allow our voices to help shape response, policy, and protocol at a variety of levels. And yet, it may only go so far in mitigating some of the negative personal impacts that have been reverberating for so many around the globe. We are experts, we have passion, and we do amazing work. And we are only human. We each can only do and be so much. And that is okay too. At its core, AAZV is about helping our members help animals. The organization’s mission is to empower our members to advance our profession and enhance wild animal health, welfare, and conservation. This continuing education conference opportunity – and the associated formal and informal learning and networking opportunities – remains an important component of that work. Even in the virtual space. And even in a time like this. I personally continue to believe in our work…. helping animals, advancing conservation… and feel it is as important as ever. Perhaps even more important. Spending a little time focusing on this work, celebrating the accomplishments of others, learning new things, commiserating about challenges – that all continues to have meaning for me. And I hope for you. Thank you all for being here, for being part of this community. Leigh Leigh Clayton President, American Association of Zoo Veterinarians AMERICAN ASSOCIATION OF ZOO VETERINARIANS “Dedicated to wildlife health and conservation” 581705 White Oak Road Yulee, Florida, 32097 904-225-3275 Fax 904-225-3289 Dear Colleagues, Welcome to our 52nd AAZV Annual Conference and first-ever Virtual Conference! These are certainly challenging times. As much as we love our face-to-face conference and social interactions, our current crisis dictates we explore a new direction. We want to ensure that as veterinarians working on the frontlines of zoological animal medicine, we have the opportunity to share and learn from the outstanding work of our friends and colleagues. Our virtual conference will provide an excellent venue to share that knowledge and we are looking forward to seeing your faces on our screens. On behalf of the Scientific Program Committee, we are delighted to share this year’s thoughtfully crafted program with you. Your hard-working SPC members responsible for the 2020 conference program and workshops are Sam Sander, Alicia Hahn, Kurt Sladky, and Matt Kinney. We are also grateful to Heather Robertson and Margarita Woc Colburn from the Nashville Zoo who worked hard at the early stages of planning in hopes of meeting in Nashville. We are looking forward to meeting them there in the not-too-distant future. There are seventeen scientific sessions of varying length scheduled over four days. Some sessions are taxon-specific (Aquatics, Avian, Carnivores, Elephants, Primates, Megavertebrates, Mammals, and Herptile) and others are organized by topic (Conservation, Diagnostics, Wildlife Rehabilitation, Mycology, Cardiology, Anesthesia, Animal Welfare, and Leadership and Training). We will have two masterclasses: Successful Management of an Animal Health Crisis at a Zoological Institution and Aquatic Medicine. We are fortunate to have Dr. Jen Brandt from the American Veterinary Medical Association to open our conference with a keynote talk entitled: Mission Possible: Creating a Culture of Wellbeing. There will also be a variety of posters to enhance our educational experience. The 36 session chairs chose 95 submissions for oral presentations and 24 for posters. The 22.25 hours of continuing education credits are once again being sponsored by the American College of Zoological Medicine. Up to 6.5 additional hours are available through the workshops. Workshop topics include Hospital Design, Animal Welfare, ZIMS, and the 27th Annual Zoo & Wildlife Pathology Workshop. Our virtual conference platform will allow us to have the Opening Icebreaker on Sunday evening and the student reception on Monday evening. During the breaks on Monday we will have the opportunity to visit posters. Tuesday through Thursday breaks can be used to visit the exhibitors. The platform will be open before and after the scheduled sessions to allow more socializing. We are sure this will be an unforgettable conference! The SPC would like to gratefully acknowledge the tireless efforts of Rob Hilsenroth, AAZV Executive Director, and Adine Nicholson, AAZV Director of Development, for their constant support and assistance in making this conference a success. We are also grateful to the AAZV Executive Committee for their input and support. Welcome to our virtual conference and we truly hope you enjoy the conference and our virtual time together.
