MUSIC 2TT3 Chapter Notes - Chapter 50-55: Intertidal Zone, Pollination, Red
Document Summary
Water depth limits aquatic species; climate change limits terrestrial species. Primary goal of ecology: understand the distribution and abundance of organisms. Salmon subject to parasitism and disease in freshwater and sea habitats food supply decreasing due to overfishing and damming, logging, etc. of breeding streams: ecosystem: how do energy and nutrients cycle through the environment. Ecosystem contains all of the organisms in a particular region with abiotic components. Salmon link marine and freshwater ecosystems transport chemical energy and nutrients from one habitat to another. Human induced changes have a large impact on their populations because salmon are sensitive to pollution and changes in water temp. Conservation biology: effort to study, preserve, restore threatened populations/ecosystems etc. In fresh and salt water: nutrient availability, water depth, water movement affect distribution and abundance of organisms: nutrient availability: nitrogen and phosphorus are in short supply in many aquatic ecosystems.
