Dear Colleagues, The THIRTEENTH annual Yosemite Symbiosis Workshop will take place on April 18-20th, 2025 at the Sierra Nevada Research Institute, Yosemite National Park. In the previous 12 years, this meeting became a great venue for a diversity of symbiosis researchers. We hope to continue to attract a diverse group in 2025! KEYNOTE SPEAKER: Britt Koskella, UC Berkeley https://naturesmicrocosm.com/ REGISTER HERE: https://snri.ucmerced.edu/form/symbiosis-workshop-2025 LEARN EVEN MORE HERE:https://www.sachslab.com/symbiosis-2015.php Why: Our goal is to better integrate scientists that focus on symbiosis research, including researchers that study animal-microbe and plant-microbe systems, as well as broader topics related to the microbiome, cooperation, and mutualism. This will be our 13th annual meeting and we have been consistently attracting scientists from all over the country and overseas. Who: The meeting is small and intimate by design (~50 participants). We would like to make room for a diverse group of people so we will initially accept up to 3 lab members per group (including the PI) on a first come first served basis. In the past we have covered a range of symbiosis topics from ecology and evolution to molecular mechanisms in different model and non-model systems. What: The meeting will be made up of two half-days of talks and one poster session. Other than the keynote (~1 hour), talks are 15 minutes long (including time for questions). Posters are flexible for size, but the ideal poster should be no larger than ~4 feet square. When you apply for the meeting, you will provide your preference for a talk or poster. When: Participants generally arrive Friday afternoon or evening (April 18) and depart Sunday early afternoon (April 20). Though some attendees often extend their stay at the station to spend more time at the National Park. Where: This is the best part! The meeting takes place at the Sierra Nevada Research Station, in Wawona California, within the borders of Yosemite National Park! What will it cost? $250 for graduate students, undergraduate students, and postdocs, $300 for PIs and other types of participants (e.g. industry/foundation/journalist). We may have funding for graduate students and postdocs, so graduate students and postdocs don't need to pay for now to register. PIs must pay a registration fee of $300. The registration deadline is March 14, 2025. Even without the awards, we have been good at keeping costs low ( <$300 total for PIs, includes all fees: registration, room and board).
