本論文は、中国の河口湿地における養殖池の干拓が暗炭素固定（DCF）速度を中程度・高強度の養殖池でそれぞれ102%と271%増加させることを示した。養殖干拓により炭素固定微生物が「ジェネラリスト」から「スペシャリスト」へとシフトし、嫌気的環境下での微生物エネルギー再配分が生じる。提案された「養殖干拓誘発熱-炭素ポンプ」概念は、人為的投入が沿岸炭素隔離とその熱感受性を強化する正のフィードバック機構を表す。
English
This paper demonstrates that aquaculture reclamation in estuarine wetlands substantially increases dark carbon fixation (DCF) rates by 102% and 271% in moderate- and high-intensity ponds. It reveals a microbial community shift from generalists to specialists due to habitat anaerobiosis, reallocating energy from growth to maintenance. The proposed 'aquaculture reclamation-induced thermo-carbon pump' concept describes a positive feedback mechanism whereby anthropogenic inputs enhance coastal carbon sequestration and thermal sensitivity.

📄 Abstract（原文）
, which respectively substantially increased by 102% and 271% in moderate- and high-intensity aquaculture ponds, establishing them as potent estuarine DCF hotspots. Aquaculture reclamation enriched carbon-fixing microorganisms, and shifted their compositions from a "generalist" (characterized by aerobic and versatile taxa) to a "specialist" (dominated by strictly anaerobic taxa) type. This shift indicated a fundamental ecological change driven by habitat anaerobiosis, triggering a microbial energy reallocation from growth to maintenance. The proposed "aquaculture reclamation-induced thermo-carbon pump" concept describes how anthropogenic inputs enhance coastal carbon sequestration and its thermal sensitivity, representing a positive feedback mechanism in carbon-climate interactions.
