A review on algae ecology in wetland

Abstract

Abstract: The research advance in algae ecology in wetland was introduced in this paper,which included the algae population structure and its function,and the algae productivity and its affecting factors. Almost all kinds of algae occured in wetland,including four assemblages: epipelon, epiphyton, metaphyton and phytoplankton, among which, diatom, green and blue algae were the predominant species. Algae were the fundamental players in the physical, chemical and biological processes that characterized wetland ecosystems. Most obvious was their role as primary producers and their place in the wetland food web. Algae were an important food resource for herbivores, and contributed to wetland nutrient cycle as the sources of dissolved organic matter and N. They could also be used as biomarkers for monitoring environment pollution. The affecting factors on algae's productivity were hydraulic factor, nutrition, temperature, illumination,herbivores and some other animals,and so on. Because of their functions in wetland, future research on algae in wetland should expand our knowledge of the environmental controls on algal biomass, productivity, and species composition in wetlands, with particular in areas for which knowledge was incomplete. Included among these,may be a detailed evaluation of the proportionate contributions by epipelon, epiphyton, metaphyton, and phytoplankton to food web dynamics in wetlands,and a further study of the genetic technique in controlling hazardous algae.
