Marine Plankton Functional Groups Variation and Ecosystem Change

Marine ecosystem plays a vital role in the economy and society because of its service and production function. Marine ecosystem always changes under the pressure of climate change and human activities. We concern about the status and future of the ecosystem, but it is very difficult to assess and predict the ecosystem health condition. Marine biodiversity is one of the very important indicators of the marine ecosystem change. We focus not only on species composition and quantity change of marine organisms. It is important to determine which are the main contributors to the structure and function of the ecosystem. According to the function of various plankton species in an ecosystem, they can be divided into different functional groups based on the similarity of their ecological roles. By studying the changes of the functional groups, we can enhance our ability to understand the structure and function of ecosystem, and to predict the trend of ecosystem change and the resultant effect on marine biological resource and environment under the multiple pressures of global climate change and human activities. This will help us to establish the marine ecosystem based management.

Driving forces and management strategies for estuaries in northern China

Estuaries, which lie at the end of rivers, belong to the interlocking area between marine ecosystems and terrestrial ecosystems. In the estuary region, there are plenty of biological resources that carry many important ecosystem services. However, severe degradation of the estuary ecosystem in northern China has been caused by anthropogenic disturbances, including water pollution from upstream area, change of marine environmental dynamics, animal habitat loss, and unreasonable exploitation in the estuary region. In order to provide scientific evidence for restoration and conservation of the estuary ecosystem, we collected data from published literature to analyze the ecological problems in several main estuary regions in northern China, such as the Yellow River estuary, Liaohe River estuary, Haihe River estuary, Yalu River estuary, and some others. The main ecological problems in the estuary region of northern China include the input decrease of fresh water from rivers, the change of the sediment input from rivers, the destruction of the estuary wetland ecosystem, the environmental pollution in the estuary region, the erosion in the estuary region, seawater encroachment, the biodiversity decline of the estuary region, and the depletion of the fish resources in the estuary region. Meanwhile, the driving forces for these ecological problems in the estuary region were also assessed. Based on the analysis of these driving forces, we propose several pieces of advice for integrated estuary management in northern China, including the creation of a management system for estuary conservation, improvement of the means and strength of the environmental law execution, increased investment on scientific research in the estuary ecosystem, improvement of public participation on the conservation for the estuary environment and biodiversity, and construction of a monitoring system for the estuary environment.     

Marine Ecosystem—Based Management: Definition,Principles, Framework and Practice

As the largest ecosystems of the earth, marine ecosystem provides many types of ecosystem service to human. More than 60% of the global population lives the coastal area. A healthy ocean is critical to our economy, health and way of life. However, with rapid population growth and densely inhabited coastal areas, our dependence on marine resources is greater than ever. The overuse and mismanagement of ecosystem services have placed great pressure on marine systems, thereby threatening the future of marine ecosystems, and the services they provide. With anthropogenic pressures increasing in coastal cities, adopting ecosystem-based management frameworks that minimize impacts on marine environments while allowing for sustainable development is critical. Marine Ecosystem-Based Management seeks to manage marine resources in ways that protect ecosystem health while providing the ecosystem services needed by people. Rather than focusing solely on a single species or resource, MEBM incorporates science and balances the demands of user groups in a manner that produces management strategies that are more likely to be sustainable than traditional approaches. The definition, principles and framework were discussed in this paper based on the summary of literature, and two examples were introduced. Last, some suggestions were put forward to marine ecosystem management for ocean ecosystem and for healthy coastal resources sustainable utilization.
