BIOL 2335 Lecture Notes - Lecture 21: Upwelling, Coral Reef, Eutrophication
Document Summary
Patterns of productivity in marine habitats differ from that of terrestrial systems. Productivity ii: cool colors (blue, purple) are low productivity, equatorial areas have less productivity unless they are close to land masses, warm colors (red, yellow, green) are high productivity, temperate regions have more productivity. Is large in open ocean and small in coastal areas due to productivity in coastal regions: coastal zone, nutrients are high = high. Ocean systems generally show nutrient limitations in euphotic zone except under certain. Global patterns of productivity in oceans and how this is different from patterns on land. How light and nutrient availability influence patterns of productivity vs depth. Freshwater is mostly influenced by nutrient upwelling, not light. It extends to depth where net primary productivity = 0. It is large in the open ocean and smaller closer to shore (like in estuaries) It reflects how far light penetrates into the water: not it is largest where aquatic/ocean productivity is the greatest.
