Presentation Transcript

  1. ECOLOGY

  2. Distribution Limits Define and give examples • Abiotic factors • Biotic factors

  3. http://biology.mhc.edu/forests/biomes.htg/biomes.jpg

  4. Distribution Limits: Biomes Provide brief description of each biome • Tundra • Taiga • Grasslands

  5. Distribution Limits: Biomes • Temperate deciduous forest • Tropical rainforest • Desert • Aquatic – intertidal, ocean, freshwater…

  6. Check Your Understanding • Match the following pictures to the biome.

  7. TAIGA DESERT A D TDF TUNDRA F B E GRASSLANDS TRF C www.teachersfirst.com/ lessons/biomes/biomes.html

  8. Population Growth • r(reproductive rate) = births-deaths N • N = size of population • Density • Dispersion Define and provide examples

  9. Population Growth • Biotic potential • Carrying capacity • Limiting factors • Density-dependent • Density-independent Define and provide examples

  10. Population Growth • Age structure • Which diagram represents ZPG/decline? • Rapid growth vs. slow growth?

  11. Population Growth & Regulation • Life History • Semelparity • Iteroparity • Survivorship curves • Type I = k-strategist (selection) • Type II = random • Type III = r-strategist (selection) Define and provide examples

  12. Survivorship Curves C. B. Number of survivors A. Relative Age

  13. Species Interactions • Interspecific competition • Competitive exclusion principle (Gause) • Resource partitioning • Character displacement • Realized niche vs. fundamental niche Define and provide examples

  14. Interspecific Competition • Predation • True predation • Parasitism • Parasitoid • Herbivory Define and provide examples

  15. Interspecific Competition • Symbiosis – sym = together, bio=life • Mutualism • Commensalism • (Parasitism Define and provide examples

  16. Interspecific Competition • Coevolution • Morphological defenses • Secondary compounds • Camouflage • Aposematic coloration • Mimicry • Műllerian • Batesian Define and provide examples

  17. Community Structure & Growth • Ecological Succession • Primary • Secondary Describe the changes that occur from left to right in the picture? If the original plot was plowed, is this primary or secondary succession? http://www.geo.arizona.edu/Antevs/nats104/00lect20sucn2.gif

  18. Biogeochemical Cycles Consist of same basic structure/parts: • Major chemicals • Reservoir/storage • Assimilation (into organisms) • Release (from organisms) For each cycle that follows provide an example of the information above.

  19. Water cycle • Major chemicals ….water (duh!) • Reservoir/storage • Assimilation (into organisms) • Release (from organisms)

  20. Water Cycle http://www.marietta.edu/~biol/102/ecosystem.html

  21. Carbon Cycle • Major chemicals • Reservoir/storage • Assimilation (into organisms) • Release (from organisms)

  22. Carbon cycle http://www.safeclimate.net/business/images/understanding_carboncycle.jpg

  23. Nitrogen Cycle • Major chemicals • Reservoir/storage • Assimilation (into organisms) • Release (from organisms)

  24. http://msucares.com/crops/soils/images/nitrogen.gif

  25. Phosphorus Cycle • Similar to others but does not have an atmospheric component. • See pg. 1212 for details.

  26. Energy Flow • Trophic levels –define and provide examples. • Primary • Secondary • Tertiary/quaternary

  27. Ecological Pyramids • Energy-Why is a percentage of energy lost as you ascend the pyramid? http://www.mesa.edu.au/friends/seashores/images/energy_pyramid.gif

  28. Ecological Pyramids • Biomass – Why does the biomass pyramid reflect the same trend as the energy pyramid? http://www.niles-hs.k12.il.us/jacnau/chpt545.jpg

  29. Following the Flow • Food chains – Create a simple, but specific example. • Food webs - Create a simple example using at least 10 organisms.
