Data for 'Expansion of intertidal mussel beds following disease-driven reduction of a keystone predator'

To test whether the absence of keystone predation due to disease produced changes to the species composition of rocky intertidal communities, I took advantage of a natural experiment involving mass mortality of the keystone predator Pisaster ochraceus from Sea Star Wasting Syndrome. This data contains records of mussel size, mussel position, mussel bed depth, species composition, and changes to the sea star populations of the North American Pacific coast.

为验证因疾病导致的关键捕食者捕食作用缺失是否会改变岩相潮间带群落的物种组成，本研究利用了一场由海星消瘦综合征（Sea Star Wasting Syndrome）引发北美太平洋海岸关键捕食者赭色海星（Pisaster ochraceus）大规模死亡的自然实验。本数据集收录了该区域的贻贝尺寸、贻贝栖息位置、贻贝床深度、物种组成以及海星种群变化的相关记录。
