侵入性物种研究侵入性物种研究

背景情况:

人类影响和气候变化显著改变水生生态系统.
侵入性物种研究往往集中在大型河流上,忽视了人类影响较小的较小河流.
对于外来物种入侵,人类影响较弱的小河流研究不足.

研究的目的:

在研究较少的,人类影响较低的河流中调查外来藻类物种.
在伏尔加的支流中识别侵入性植物浮游生物和微生物.
评估环境变化在促进入侵的作用.

主要方法:

对文献数据和长期植物浮游生物观测的分析.
用了形态和分子遗传方法来识别物种.
研究了浮游生物和谷底藻类社区.

主要成果:

在伏尔加左岸支流中确定了六种入侵藻类,主要是藻.
记录了入侵物种的存在,例如*Thalassiosira incerta*,*Skeletonema subsalsum*和*Gonyostomum精液*.这些物种的存在已经被证实.
观察到盆地物种 *Plagiotropis lepidoptera* 的变种. *proboscidea* 在浮游生物中取得了显著的生物量.

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.

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.
