The sunburst anemone Anthopleura sola is an abundant species inhabiting the intertidal zone of coastal California. Historically, this species has extended from Baja California, Mexico to as far north as Monterey Bay, CA. However, recently the geographic range of this species has expanded to Bodega Bay, CA, possibly as far north as Salt Point, CA. This species also forms symbiotic partnerships with the dinoflagellate Breviolum muscatinei, a member of the family Symbiodiniaceae. These partnerships are analogous to those formed between tropical corals and dinoflagellate symbionts, making A. sola an excellent model system to explore how hosts will (co)evolve with novel symbiont populations they encounter as they expand northward. This assembly will serve as the foundation for identifying the population genomic patterns associated with range expansions, and will facilitate future work investigating how hosts and their symbiont partners will evolve to interact with one another as geographic ranges shift due to climate change.
