背景情况:
- 生物多样性危机需要对人与自然的相互作用进行可持续的管理.
- 生态系统服务 (ES) 提供了一个有利于人类和自然的决策框架.
- 海洋生态系统面临着污染和气候变化等驱动因素的重大威胁,但ES在这一领域的研究落后于陆地系统.
研究的目的:
- 系统地绘制科学文献,以了解海洋生态系统的变化如何影响生态系统服务 (ES) 的提供.
- 识别海洋ES研究中的知识集群和差距.
- 为未来的研究方向和可持续发展的海洋管理政策制定提供信息.
主要方法:
- 在学术和灰色文学数据库 (Scopus,科学网,谷歌学者,政府间/非政府组织数据库) 进行了系统的文献搜索.
- 包括标准适用于标题,摘要和全文,没有地理或时间限制.
- 包含的文章被编码为元数据,以识别有关生态系统类型,生物多样性组件,ES类型和压力的知识集群和差距.
主要成果:
- 包括1977年至2021年7月间发表的653篇文章,揭示了研究分布不均.
- 海底和潮间生态系统是最受研究的;深海和与冰相关的生态系统是最不受研究的.

Keystone Species
21.6K
Measures of species biodiversity, such as richness (i.e., the number of species present) and evenness (i.e., their relative abundance), describe an ecological community’s structure. Many factors affect community structure, including abiotic factors (e.g., sunlight and nutrients), disturbances (e.g., fire or flood), species interactions (e.g., predation or competition), and chance events (e.g., foreign species invasion). Certain species—such as keystone species—also play a...

Ecological Disturbance
17.0K
An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.

Sustainable Development

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

What is Biodiversity?
27.2K
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.

Threats to Biodiversity
22.2K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
