A dynamic energy budget (DEB) model integrating pCO was used to describe ocean acidification (OA) effects on Atlantic surfclam, Spisula solidissima, bioenergetics. Effects of elevated pCO on ingestion and somatic maintenance costs were simulated, validated, and adapted in the DEB model based upon growth and biological rates acquired during a 12-week laboratory experiment. Temperature and pCO were projected for the next 100 years following the intergovernmental panel on climate change representative concentration pathways scenarios (2.6, 6.0, and 8.5) and used as forcing variables to project surfclam growth and reproduction. End-of-century water warming and acidification conditions resulted in simulated faster growth for young surfclams and more energy allocated to reproduction until the beginning of the 22nd century when a reduction in maximum shell length and energy allocated to reproduction was observed for the RCP 8.5 scenario.
采用一个整合了 pCO₂的动态能量预算（DEB）模型来描述海洋酸化（OA）对大西洋美洲帘蛤（Spisula solidissima）生物能量学的影响。根据在为期 12 周的实验室实验中获得的生长和生物学速率，对升高的 pCO₂对摄食和躯体维持成本的影响进行了模拟、验证和改编。根据政府间气候变化专门委员会（IPCC）的代表性浓度途径情景（2.6、6.0 和 8.5）预测了未来 100 年的温度和 pCO₂，并将其作为强迫变量来预测美洲帘蛤的生长和繁殖。本世纪末的水变暖与酸化条件导致年轻美洲帘蛤的生长速度加快，用于繁殖的能量增加，直到 22 世纪初，才观察到 RCP 8.5 情景下最大壳长和用于繁殖的能量减少。
