Seawater carbonate chemistry and shell mineralogy, epibiont abundance, and growth of juvenile American lobster Homarus americanus

We examined the combined effects of ocean warming and acidification on shell mineralogy, epibiont abundance, and growth in early benthic juveniles of American lobster Homarus americanus H. Milne Edwards, 1837 (Decapoda: Astacidea: Nephropidae), a commercially important species. Lobsters were grown under six different temperature/pCO2 treatment conditions over 52 days (three replicates per treatment) aligned with environmentally relevant as well as predicted future extremes.

本研究探究了海洋增温与酸化对美洲螯龙虾（Homarus americanus H. Milne Edwards, 1837，十足目Decapoda、螯虾下目Astacidea、螯龙虾科Nephropidae）这一重要商业物种的早期底栖幼体壳体矿物学特征、附生生物丰度及生长的联合影响。实验将该幼体置于6种不同温度/二氧化碳分压（pCO2）处理条件下培养52天，每个处理设置三次生物学重复，实验条件均契合当前环境相关参数及预测的未来极端环境水平。
