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.
太阳花海葵 Anthopleura sola 是一种广泛分布于加利福尼亚沿海潮间带的物种。历史上，这种物种从墨西哥下加利福尼亚延伸到加利福尼亚州蒙特雷湾以北。然而，最近这种物种的地理分布范围已经扩大到加利福尼亚州的博德加湾，可能向北延伸到加利福尼亚州盐点。这种物种还与虫黄藻 Breviolum muscatinei 形成共生关系，虫黄藻是 Symbiodiniaceae 家族的一员。这些伙伴关系类似于热带珊瑚与虫黄藻共生体之间形成的关系，这使得 A. sola 成为一个极好的模型系统，可以研究宿主在向北扩展时如何与它们遇到的新型共生体种群共同进化。该集合将作为确定与范围扩展相关的种群基因组模式的基础，并将促进未来的工作，研究由于气候变化导致地理范围转移，宿主及其共生伙伴如何进化以相互作用。
