tailieunhanh - CALIFORNIA’S CONTAMINATED GROUNDWATER-Is the State Minding the Store?

Water temperature plays an important role in signaling biological functions such as spawning and migration, and in affecting metabolic rates in aquatic organisms. Altering natural water temperature cycles can impair reproductive success and growth patterns, leading to long-term population declines in fisheries and other classes of organisms. Warmer water holds less oxygen, impairing metabolic function and reducing fitness. Such impacts can be especially severe downstream of thermal or nuclear power generation facilities or industrial activities, where the return of water to the streams may be substantially warmer than ecosystems are able to absorb (Carr and Neary 2008).
