We thank Yang et al. (1) for their perspective. We are aware of the importance of coastal wetland protection for endangered migratory birds. Our paper in PNAS (2) focuses on the general representation of protected areas for endangered species (e.g., endangered birds) and ecosystem services. Thus, we did not emphasize the representation in nature reserves of coastal wetlands for endangered migra...
Empirical relationships between phytoplankton biomass and nutrient concentrations established across a wide range of different ecosystems constitute fundamental quantitative tools for predicting effects of nutrient management plans. Nutrient management plans based on such relationships, mostly established over trends of increasing rather than decreasing nutrient concentrations, assume full reve...
Marine pollution has been a hot issue since 1990s around the world. Chua discussed marine pollution prevention and management in the East Asian Seas, concentrating on pollution caused by land and sea based sources [2]. The land based sources included destruction of coastal habitats, urban effluents discharge and coastal sand mining has resulted in serious coastline erosion. Sea based sources in...
Radars are extremely useful in homeland security for border management and coastal surveillance systems. Due to the terrain, coastal and vegetation conditions a network of short ranged radars are advantageous over single long range radar. Integrating radars in terms of data acquisition and display remains challenging considering the factors like synchronicity, network failures, and channel band...
Community involvement and empowerment are central to the notion of environmental democracy. In contrast to decide-announce-defend modes of centralised decision making, planning and management, decisions built on inclusive participation and knowledge sharing are more likely to be supported during implementation, mobilise resources and support, and facilitate social learning. Collaborative modes ...
It is generally considered that nitrogen availability is one of the major factors regulating primary production in temperate coastal marine environments. Coastal regions often receive large anthropogenic inputs of nitrogen that cause eutrophication. The impact of these nitrogen additions has a profound effect in estuaries and coastal lagoons where water exchange is limited. Such increased nutri...
both climate change and anthropogenic impact are creating a dynamic of continuous changes in ecosystems. while the expected consequences of these changes are global, the occurrence of extreme events and specific environmental problems are usually local or regional phenomenon. in particular, the coastal ecosystems are among the first vulnerable areas to show those changes; in spite of this, are...
Forests are receiving more attention for the ecosystem goods and services they provide and the potential change agents that may affect forest health and productivity. Highlighting case examples from coastal forests in South Carolina, USA, we describe groundwater processes with respect to stressors and potential responses of a wetland-rich forested landscape, the roles that this area has served,...
