Symbioses - the lasting interactions between living organisms - can range from mutually beneficial relationships to harmful pathogenic effects. This interdisciplinary meeting will explore symbiotic interactions in ecological, evolutionary, chemical, spatial, and methodological contexts, ranging from deep mechanistic studies to broader surveys. Our primary objective is to unite researchers and establish new interactions between symbiotic systems and fields. We hope this serves as an incentive to generate new ways of thinking in established fields and spur new directions in symbiosis research.
