Dear MARMAM Community- Please join us for the Eleventh International Sirenian Symposium—a full day dedicated to fostering international collaboration, networking, and mentorship among those engaged in sirenian research and conservation. The Symposium aims to support collaboration and strengthen sirenian research networks across the 80+ range states, with a particular focus on the 70+ developing countries within this range. Objectives include sharing new scientific findings, addressing current and emerging threats, and promoting mentorship for students pursuing careers in marine mammal science and conservation. Presentations may cover a wide range of topics, including human–sirenian interactions, physiology, monitoring applications, modeling, genetics, captive care and rehabilitation, management, general biology, stranding response, and education and outreach. The program will feature full-length presentations, speed talks, a poster session, an update from the Sirenian Specialist Group, and dedicated time for networking. Those interested in presenting research (poster or oral) should submit an abstract by *August 15, 2026* to Nicole Adimey at: adimey22@gmail.com. Abstract formatting guidelines are available on the conference website: https://www.smmconference.org/abstract-submission. Preference will be given to researchers from developing countries and abstracts that address the conference theme, “One Ocean, One Future.” Presenters are encouraged to share novel work and clearly demonstrate how their research contributes to sirenian conservation and supports regional initiatives or current management challenges. -- Nicole Adimey 904-655-0730
