概括

像Plesiastrea versipora这样的温带珊瑚比宏观藻类释放出明显更多的生物源性挥发性有机化合物 (BVOC),影响海洋化学. 了解这些排放是评估生态系统贡献的关键.

科学领域:

海洋化学海洋化学
生态生态学生态生态学
生物地质化学生物地质化学

背景情况:

生物源性挥发性有机化合物 (BVOCs) 是对生理和生态功能至关重要的代谢副产品,它们共同形成挥发体.
虽然研究了热带珊瑚礁的BVOC,但温带珊瑚礁的排放仍然基本上没有特征.

研究的目的:

描述澳大利亚温带珊瑚礁中关键盆地竞争者的挥发体.
为了比较温带珊瑚 (Plesiastrea versipora) 和大藻 (Ecklonia radiata) 之间的BVOC排放.

主要方法:

珊瑚和宏藻样品在用海水修改的室内进行化.
清除和陷方法,以捕获生物体产生的BVOCs在热溶解管上.
使用气体染色体质谱法 (GC×GC-TOFMS) 和多变量统计试验对BVOC进行分析.

主要成果:

在P. versipora中检测到55个BVOC,在E. radiata中检测到63个BVOC,其中30个BVOC在P. versipora中检测到55个BVOC,在E. radiata中检测到63个BVOC,其中30个BVOC在P. versipora和E. radiata中检测到30个BVOC.
确定了明显的排放,包括基化合物,如甲和四化碳.
尽管覆盖面较低,但P. versipora每平方厘米的BVOC排放量是E. radiata的17倍,对当地排放的贡献是4.7倍.

结论:

地社区组成的变化可以不成比例地改变海洋化学.
珊瑚物种可能比宏观藻类对当地BVOC排放的贡献更大,影响生态系统功能.
需要进一步的研究,以了解这些排放对海洋生态系统和气候的更广泛影响.

Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

What are Biogeochemical Cycles?

What are Biogeochemical Cycles?

The most common elements in organic molecules, carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus, are only available in the ecosystem in limited amounts. Therefore, these nutrients must be recycled through both biotic and abiotic components of the ecosystem, in processes generally called biogeochemical cycles.

The Carbon Cycle

The Carbon Cycle

Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.
