  3. Ecosystems http://www.krisweb.com/krissheepscot/krisdb/html/krisweb/watershed/riparian_large_stream.jpg

  4. http://www.marietta.edu/~biol/biomes/biome.jpg Ecological Communities

  5. Factors Within Ecosystems Abiotic Factors http://www.hickerphoto.com/data/media/171/ocean_ecosyste

  6. Biotic Factors http://surguja.nic.in/images/Elephant-1.jpg

  7. Species Diversity Variation of life forms within an ecosystem or on the Earth http://www.egurucool.com/images/is/imgRep/82/1213/4.jpg

  8. Species Richness and Species Evenness http://www.okstate.edu/artsci/botany/bisc3034/lnotes/images/evenness.gif

  9. Species Richness • Number of species present in an ecosystem • Species Evenness • Relative abundance of individuals among the species • If lopsided it can mean trouble (e.g crows)

  10. Species Diversity- Why do we care? • Measure of the health of an ecosystem • More species = healthier ecosystem • Human benefits • Air quality • Water quality • Disease control • Pest control • pollination

  11. Keystone Species Species that has a disproportionate effect on its environment (e.g. salmon or the sea otter) http://kelewis.com/images/animation/animation3a.jpg
