概括

这项研究区分了生物污染与海洋生态系统中的生物污染. 它提出了一种渐变的方法来评估非土著和入侵性外来物种对更好的生态系统健康管理的影响.

科学领域:

海洋入侵生态海洋入侵生态
生态系统健康评估生态系统健康评估
环境政策分析环境政策分析

背景情况:

海洋生态系统面临来自引入物种的挑战,需要明确的管理定义.
现有的框架往往缺乏在物种存在和生态危害之间细微的区别.
欧洲海洋战略框架指令 (MSFD) 为重新评估这些概念提供了相关的背景.

研究的目的:

在海洋生态学中重新评估引入物种作为污染物与污染物的范式.
澄清生物污染 (非土著物种 - NIS) 和生物污染 (外来入侵物种 - IAS) 之间的区别.
提出一个渐变的方法来评估生态系统的健康和NIS/IAS的影响.

主要方法:

对海洋入侵生态学原则的概念性重新评估.
使用生物污染-生物污染梯度对MSFD描述器D2 NIS的分析.
讨论NIS/IAS目前监测和评估标准的局限性.

主要成果:

引入的物种可以根据生物污染-生物污染梯度进行分类,反映不同程度的生态危害.
目前对NIS/IAS的监测和评估标准受限于缺乏统一的方法和取决于背景的结果.
为了有效干预,管理措施必须考虑压力的来源 (内源或外源).

结论:

对于管理生物污染和生物污染而言,采用整体和适应性的方法至关重要.
需要全面的指标来评估引入物种的生态,经济和社会影响.
区分污染和污染对于保护海洋生态系统和人类福祉至关重要.

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 is an Ecosystem?

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.

What is Biodiversity?

What is Biodiversity?

Biodiversity describes the variety of living things at multiple organizational levels: genetic, species and ecosystem diversity. Species diversity includes all branches of the evolutionary tree from single-celled prokaryotic organisms, bacteria, and archaea, to the eukaryotic kingdoms: plants; animals; fungi; and protists. To date, there have been about 1.75 million species identified, and new species are discovered every week.

Primary Production

Primary Production

The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.

The Soil Ecosystem

The Soil Ecosystem

Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:
