日本南部沿海的潮汐池塘栖息着钻岩的海胆棘链海胆，这种海胆在底物中挖掘坑。这些凹坑随后被非枯燥的海胆使用，如花色海胆和棘球藻属。B，重新克隆的凹坑通常栖息着一种共生帽状轮虫蜗牛物种--虹彩蜗牛。2017年5月至2019年5月，我们通过监测日本白滨潮汐池塘中512个坑的占用情况，探索了这些海胆和帽状蜗牛的种群和群落动态。最初，几乎所有的坑都被这三种海胆中的任何一种占据，但2018年2月的一次不同寻常的寒冷事件导致这些海胆大量死亡。此次活动后，入住率从99%下降到15%，热带物种棘豆属(Echinmetra sp.)B从学习池中消失了。通过潮下带亚成虫的迁徙，我们观察到石斑鱼和粗刺石斑鱼种群恢复缓慢。侵坑海胆的周转率在冷事件前为<；1.0%，但冷事件后急剧增加。共生钉螺的种群数量随着宿主的减少而减少，但共生率在整个研究期间保持在50%-55%，这表明这些钉螺跟随宿主海胆重复穴间迁徙。尽管海胆大量死亡，恢复缓慢，但海胆密度仍然足够高，足以在整个研究期间维持持续的海胆裸露。
Coastal tide pools in southern Japan are inhabited by the rock-boring sea urchin Echinostrephus molaris, which excavate pits in the substrate. These pits are subsequently used by non-boring sea urchins such as Anthocidaris crassispina and Echinometra sp. B, and the recolonized pits are often inhabited by a commensal limpet-like trochid snail species, Broderipia iridescens. We explored the population and community dynamics of these sea urchins and the limpet-like snail by monitoring occupancy of 512 pits in tide pools in Shirahama, Japan from May 2017–May 2019. Initially, nearly all pits were occupied by any one of the three sea urchin species, but an unusual cold event in February 2018 caused a mass die off of these sea urchins. After this event, occupancy decreased from 99% to 15%, and the tropical species Echinometra sp. B disappeared from the study pools. We observed slow population recovery of E. molaris and A. crassispina, provably via migration of sub-adults from the subtidal zone. Turnover rate of the pit-occupying sea urchin species was <1.0% before the cold event, but drastically increased after the cold event. Population size of the commensal snail decreased along with those of their host, but the rate of commensalism was constant at 50–55% throughout the study period, suggesting that these snails followed their host sea urchins repeating inter-pit migration. Despite mass mortality and slow recovery, the sea urchin density remained high enough to maintain persistent sea urchin barrens throughout the study period.
