Diatoms are the most recently added major algal lineage in the geological record, yet today they play a dominant role in ocean biological carbon sequestration and support of Earth’s largest fi sheries. In their study published in this issue, Behrenfeld et al. (this issue; Article e01457; doi: 10.1002/ecm.1457) conclude that specifi c physiological attributes linked to predator–prey dynamics and speciation rates are responsible for the diatom’s grand success.

硅藻是地质记录中最近添加的主要藻类谱系，但今天它们在海洋生物碳固存和支持地球上最大的渔业方面发挥着主导作用。在本期发表的研究中，Behrenfeld 等人。（本期；第 e01457 条；doi：10.1002/ecm.1457）得出结论，与捕食者-猎物动态和物种形成率相关的特定生理属性是硅藻取得巨大成功的原因。图中是一个中心物种的扫描电子显微照片，展示了一种重要而独特的硅藻属性，一种高度专业化的硅质细胞壁（硅藻壳）。照片来源：MC Carbonell-Moore。
