SBC LTER: Reef: Defenses of macroalgae and effects on epifaunal larvae

Larvae of the solitary ascidian , Ciona
robusta , were placed in petri dishes with various
species of macroalgae from the Santa Barbara Channel, and larval
survival to settlement was assessed. The total phenolic contents
(indicative of defensive chemicals) of the algae species were also
measured, and a correlation between larval survival and phenolic
content investigated. Experiments took place in Spring and Summer
2024. Data are contained in two tables: 1) larval survival in
control treatments (not exposed to algae), 2) larval survival in
treatment dishes (exposed to algae) as well as phenolic content of
each macroalgae individual tested.

将单体海鞘（solitary ascidian）类物种粗壮海鞘（Ciona robusta）的幼虫置于盛有采自圣巴巴拉海峡（Santa Barbara Channel）多种大型藻类（macroalgae）的培养皿（petri dishes）中，并评估其至附着阶段的幼虫存活率。同时测定了各藻类物种的总酚含量（total phenolic contents，作为防御性化学物质（defensive chemicals）的指示指标），并探究了幼虫存活率与酚类含量之间的相关性。实验于2024年春季与夏季开展。数据集包含两张表格：1）对照组（control treatments，未接触大型藻类）的幼虫存活率；2）处理组培养皿（treatment dishes，接触大型藻类）的幼虫存活率，以及所测试的每一株大型藻类的酚类含量。
