Chemical signaling plays a major role in shaping life history processes that drive ecology and evolution in marine systems, notably including habitat selection by marine invertebrate larvae that must settle out of the plankton onto the benthos.1 For larvae, the identification of appropriate habitats in which to settle and undergo metamorphosis to the adult form relies heavily on the recognition of cues indicative of a favorable environment. By documenting settlement responses of larvae of the tropical abalone, Haliotis asinina, to a range of coralline algae species, we recently highlighted the species-specific nature of this interaction.2 Here, we demonstrate that this specificity is likely driven by chemical, rather than physical, properties of the algae. Our initial characterization of the surface cell biomarkers from three different algal species shows that inductive cue biomolecular composition correlates with variations in larval settlement response.
化学信号在塑造驱动海洋系统生态与进化的生活史过程中发挥着重要作用，尤其包括海洋无脊椎动物幼虫的栖息地选择，这些幼虫必须从浮游生物沉降到底栖生物上。1对于幼虫而言，识别适宜沉降并变态为成虫形态的栖息地，在很大程度上依赖于对表明环境适宜的线索的识别。通过记录热带鲍鱼（Haliotis asinina）幼虫对一系列珊瑚藻物种的沉降反应，我们最近强调了这种相互作用的物种特异性。2在这里，我们证明这种特异性可能是由藻类的化学性质而非物理性质驱动的。我们对三种不同藻类物种的表面细胞生物标志物的初步表征表明，诱导线索生物分子组成与幼虫沉降反应的变化相关。
