Increased algal biomass can potentially deplete dissolved oxygen levels within the reservoir through bacterial decomposition and photosynthetic respiration. A study by Dr. Bayne examined the relationship between reservoir water retention times and phytoplankton algae production in the summer. Dr. Bayne‚ along with Auburn University professor Dr. Mike Maceina‚ assessed the potential water quality effects on Weiss Lake of the draft Coosa River water-sharing agreement between Alabama and Georgia

Sharks play a big role in balancing out marine life. They eat very efficiently they eat old‚ young‚ sick and slow fish. They set the marine life to the right size to fit the ecosystem. Scientist consider sharks as the “keystone” species. If the sharks aren’t there then the ecosystem would collapse. The ecosystem depends on them‚ without sharks the population would be over crowded. If the oceans were of crowded then there would be no room for any sea animal and everything would just collapse. We need

as the “Greenbelt”. Nutrient upwelling from the cold waters of the Aleutian basin flowing up the slope and mixing with shallower waters of the shelf provide for constant production of phytoplankton. The second driver of productivity in the Bering Sea is seasonal sea ice that‚ in part‚ triggers the spring phytoplankton bloom. Seasonal melting of sea ice causes an influx of lower salinity water into the middle and other shelf areas‚ causing stratification and hydrographic effects which influence productivity

Identity of Cyanobacterial Toxins Cyanobacterial toxins are toxins produced by cyanobacteria‚ or blue-green algae. They include neurotoxins (e.g.‚ anatoxins)‚ hepatotoxins (e.g.‚ microcystins)‚ skin irritants and other toxins. Both hepatotoxins and neurotoxins are produced by cyanobacteria commonly found in surface water supplies and therefore appear to be of most relevance to water supplies at present.1-3 However‚ the neurotoxins are relatively unstable and‚ as such‚ are not considered to be as
