Growth and mortality of lobster larvae at different temperatures for lobster larvae from Gulf of Maine near Boothbay Maine from 2021 and 2022 (Lobster Thermal Thresholds project)

We used the American lobster (Homarus americanus lsid:marinespecies.org:taxname:156134) in the Gulf of Maine as a model system to define thermal tolerance in larvae and establish mechanistic linkages between thermal tolerance of the individual larva and the patterns of settlement in the field. We assessed and compared the thermal tolerances of larvae reared in the laboratory using conventional methods with larvae captured in the wild, and examined ontogenetic changes in thermal tolerance. The upper and lower thermal thresholds larval stages I-IV and the first juvenile stage were defined in part by growth and mortality when subjected to chronic exposure to different treatment temperatures until they either molted to the next developmental stage or died. This data set includes individuals dying, the size after molting and the amount of time elapsed between the start of the treatment and either molting or death. These data were collected between 2021-2022 at Bigelow Laboratory for Ocean Sciences, led by Eric Annis.本研究以缅因湾的美国龙虾（American lobster，学名*Homarus americanus*，分类学标识符lsid:marinespecies.org:taxname:156134）为模型系统，旨在明确其幼虫的热耐受性，并建立单个幼虫的热耐受性与野外沉降模式之间的机制性关联。我们评估并对比了实验室常规培育方法获得的幼虫与野外捕获幼虫的热耐受性，同时探究了热耐受性的个体发生变化。I-IV期幼虫及首个幼体阶段的上下热阈值，部分通过在不同处理温度下进行长期暴露实验确定：暴露过程中持续观测直至受试个体蜕皮进入下一发育阶段或死亡，实验指标包括生长与存活情况。本数据集涵盖死亡个体信息、蜕皮后的体型大小，以及从处理开始至蜕皮或死亡所经历的时长。这些数据于2021年至2022年间在毕格罗海洋科学实验室（Bigelow Laboratory for Ocean Sciences）收集，由Eric Annis主导开展。
