Abstract
ABSTRACT Context Coastal wetlands are ecotones interspaced by land and ocean and are among the most sensitive and vulnerable ecosystems worldwide. They are unique in hydrological, edaphic, atmospheric, and biological characteristics, and play important roles in maintaining the ecological security and ecosystem services of coastal zones. Arbuscular mycorrhizae (AM) are symbiont composed of plant roots and arbuscular mycorrhizal fungi (AMF), which are soil-borne microorganisms widely distributed in various habitats. Many previous studies on mycorrhiza have focused on terrestrial ecosystems while few on wetlands, especially coastal wetlands. Method We systematically reviewed previous relevant studies to explore the formation and functions of AM in coastal wetland ecosystems as well as the environmental factors that affect them. Habitat characteristics, morphological types, and species diversity of AMF in the coastal wetlands were summarized. Both responses of AMF to environmental factors during AM formation and the functions of AM in coastal wetlands were discussed. Result AMF are worldwide distributed in coastal wetland and are mainly limited by flooding, hypoxia, soil pH, salinity and the host plants identification. AMF play important roles in coastal wetlands, involving promoting nutrient uptake of host plants, improving the characteristics of rhizospheric soil, and enhancing plant resistance to salt and flooding stress. Conclusion More comprehensive studies of AMF in vitro in coastal wetlands would be helpful for the conservation and restoration of coastal wetland ecosystems in the changing world.
期刊介绍:
Ecosystem Health and Sustainability publishes articles on advances in ecology and sustainability science, how global environmental change affects ecosystem health, how changes in human activities affect ecosystem conditions, and system-based approaches for applying ecological science in decision-making to promote sustainable development. Papers focus on applying ecological theory, principles, and concepts to support sustainable development, especially in regions undergoing rapid environmental change. Papers on multi-scale, integrative, and interdisciplinary studies, and on international collaborations between scientists from industrialized and industrializing countries are especially welcome.
Suitable topics for EHS include:
• Global, regional and local studies of international significance
• Impact of global or regional environmental change on natural ecosystems
• Interdisciplinary research involving integration of natural, social, and behavioral sciences
• Science and policy that promote the use of ecological sciences in decision making
• Novel or multidisciplinary approaches for solving complex ecological problems
• Multi-scale and long-term observations of ecosystem evolution
• Development of novel systems approaches or modeling and simulation techniques
• Rapid responses to emerging ecological issues.
