Differences in mean oxygen consumption of fed and unfed larvae used to understand the metabolic cost of digestion, Specific Dynamic Action (SDA), under ocean acidification and warming treatments - Experiments 2a and 2b

These data include the differences in mean oxygen consumption of fed and unfed larvae used to understand the metabolic cost of digestion, Specific Dynamic Action (SDA), under ocean acidification and warming treatments. Data was collected in the summers of 2021 and 2022 using a microplate reader system that uses optical fluorescence to measure dissolved oxygen concentrations in water. Knowing the energetic cost of digestion under future climate change is important as studies, particularly on larval fish, begin to investigate how energy budgets will change. These data help us to understand an important part of daily metabolic costs and how that cost might change under ocean acidification and warming. Data were collected by Emma Siegfried and Dr. Darren Johnson at California State University, Long Beach. These data are from experiments 2a and 2b. Experiment 2a contains delta VO2 values to describe the SDA curve for a single feeding under 4 experimental treatments (low temperature & low CO2; low temperature & high CO2; high temperature & low CO2; high temperature & high CO2). In experiment 2a, food ration was increased at high temperatures. Experiment 2b contains delta VO2 values to describe the SDA curve for a single feeding under the same 4 experimental treatments, except that food ration was held constant across all temperature and CO2 treatments.

本数据集涵盖摄食与未摄食幼体的平均耗氧量差值，用于解析海洋酸化与增温处理下的消化代谢成本——特殊动力作用（Specific Dynamic Action，SDA）。本数据于2021年与2022年夏季采集，采用基于光学荧光法的微孔板读数仪系统（microplate reader system）测量水体溶解氧浓度。在未来气候变化背景下明确消化的能量成本具有重要意义，当前诸多研究尤其是针对鱼类幼体的研究正着手探索能量收支的变化规律。本数据集有助于我们理解日常代谢成本的核心组成部分，以及海洋酸化与增温情境下该成本的潜在变化趋势。数据由加州州立大学长滩分校的Emma Siegfried与Darren Johnson博士采集，源自实验2a与实验2b。实验2a包含4种实验处理（低温低CO₂、低温高CO₂、高温低CO₂、高温高CO₂）下单次投喂的特殊动力作用曲线对应的耗氧变化量（ΔVO₂），且该实验中高温组的投喂量有所提升。实验2b同样包含上述4种实验处理下单次投喂的特殊动力作用曲线对应的ΔVO₂值，唯一区别在于其所有温度与CO₂处理组的投喂量均保持恒定。
