Effects of Enhanced Solar Ultraviolet Radiation on Aquatic Ecosystems

摘要: The photosynthetic production of organic biomass using solar energy is the almost exclusive source for life on our planet. amount carbon in form its dioxide incorporated annually into molecules exceeds 100 gigatons which can be visualized by load filling 10 coal trains spanning distance from earth to moon (Hader et al., 1989). However, only about one third this enormous accounted terrestrial plants — forests, savannas, crop etc. while majority produced phytoplankton organisms (primary producers) aquatic habitats, especially world oceans. marine communities represent far largest ecosystem (Schneider, 1989); therefore even a small percentage decrease populations would result losses productivity these organisms, could have dramatic effects both intricate itself and humans, who depend system many ways
