Abstract

The in situ production of methane was monitored in several types of tropical benthic communities. A bed of Thalassia testudinum located in Caesar Creek (Florida Keys) exhibited the highest methanogenic activity (initial rates = 1.81 to 1.86 mumol CH4/m2 per h) as compared with another seagrass (Syringodium sp., 0.15 to 0.33 mumol/m2 per h) and two coral reef environments (Hydro-Lab, 0.016 to 0.10 mumol/m2 per h; Curacao, 0.14 to 0.47 mumol/m2 per h). The results suggest that a wide variety of benthic metabolic processes (e.g., photosynthetic oxygen production) influences methane production rates.

摘要

对几种热带底栖生物群落中的甲烷原位生成情况进行了监测。位于凯撒溪(佛罗里达群岛)的一片泰来藻床表现出最高的产甲烷活性(初始速率为每小时1.81至1.86 μmol CH₄/m²),与之相比,另一种海草(Syringodium sp.,每小时0.15至0.33 μmol/m²)以及两个珊瑚礁环境(Hydro-Lab,每小时0.016至0.10 μmol/m²;库拉索岛,每小时0.14至0.47 μmol/m²)的产甲烷活性较低。结果表明,多种底栖生物代谢过程(如光合产氧)会影响甲烷生成速率。
