概括

湿地恢复可以将碳来源转化为碳汇,但需要几个世纪才能实现气候效益. 保护现有的湿地对减缓气候变化比恢复工作更有效.

科学领域:

环境科学环境科学
生态生态学生态生态学
气候科学气候科学

背景情况:

淡水湿地对全球碳循环产生重大影响,作为关键的碳汇.
这些重要生态系统的退化减少了它们的碳吸收能力.
生态恢复被提议作为气候解决方案,但其有效性和时间表尚不清楚.

研究的目的:

用全球元分析来评估湿地恢复对气候的好处.
为了确定恢复湿地从碳源转向碳汇所需的时间.
评估温室气体排放 (甲和氧化) 对恢复效益的影响.

主要方法:

全球对湿地恢复研究的元分析.
评估生态系统的碳和温室气体净平衡.
泥炭地和非泥炭湿地的比较,考虑到不同的退化和恢复状态.

主要成果:

大多数恢复的泥炭地 (77%) 和所有自然的泥炭地都是碳汇,而退化泥炭地 (69%) 是碳的来源.
非泥炭湿地的甲排放量在退化,恢复和自然状态之间没有显著差异.
恢复的泥炭地需要525年,非泥炭湿地需要141年才能达到净气候降温效应.

结论:

湿地恢复的好处,特别是实现净气候降温的时间,可能与"巴黎协定"的时间表不一致.
优先保护和保护现有的天然淡水湿地对于立即缓解气候变化至关重要.
虽然恢复有其作用,但其长期利益需要专注于保护完整的生态系统.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

The Water Cycle

The Water Cycle

The Earth’s hydrosphere includes all of the areas where the storage and movement of water occurs. Since water is the basis of all living processes, the cycling of water is extremely important to ecosystem dynamics.

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.

Global Climate Change

Global Climate Change

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
