6. Climate Change Monitoring Climate Change Carbon Footprint

8. Ecological Organization Ecology - relationships between organisms and their environment

9. Monitoring Climate Change in the Smokies Monitoring Climate Change Video Clip

10. Characteristics of Ecosystems Requirements –Constant flow of energy from the sun –Cycle of materials Abiotic Factors of Ecosystems (nonliving)Abiotic –Light, temperature, water, soil, gases, pH –Also called limiting factors Biotic Factors of Ecosystems (living)Biotic –Trees, animals, fungi, bacteria

11. Biotic Vs. Abiotic

12. Biotic Factors

13. · Organisms that look alike, can mate among themselves, and produce fertile offspring. Species

14. Population all members of a species living in a particular location

15. Community interacting populations (white tail deer, maple trees, coral reef, etc.)

16. Ecosystem members of a community and their physical environment The organisms plus: –Water –Temperature –Sunlight –pH

17. Community How does a community differ from a population? An ecosystem?

18. Habitat vs. Niche Habitat –environment in which an organism lives Niche – the role a species fills in its habitat (what it eats, where it lives)

19. Niche coyote wolf NC State Bird What is this bird? NC State Mammal

20. Symbiotic Relationships - living together in close association Mutualism –both organisms benefit Parasitism – 1 organism benefits, the other is harmed

21. Symbiosis Song Mr. Parr http://www.youtube.com/watch?v=1zL TwQklddc&feature=relatedhttp://www.youtube.com/watch?v=1zL TwQklddc&feature=related

22. Mutualism Lichens – algae And fungi

23. Figure 31.17 Anatomy of a lichen

24. A remarkable 3-way mutualism appears to have evolved between an ant, a butterfly caterpillar, and an acacia in the American southwest. The caterpillars have nectar organs which the ants drink from, and the acacia tolerates the feeding caterpillars. The ants appear to provide some protection for both plant and caterpillar. Mutualism

25. Figure 28.x1 Trichonympha These guys are found in the digestive tract of termites – they digest cellulose for termites!

26. Mutualism: Sea Turtles and Yellow Tang The yellow tang eat algae off the turtle!

27. Parasitism - Tapeworm

28. Parasitism - Athletes Foot

29. Parasites – Bed bugs http://www.youtub e.com/watch?v= WfKCcSPCOQo Pesticide resistance contributes to the challenge of controlling this pest.

30. Tomato Horn Worm This is the moth that the tomato horn worm becomes if it doesn’t get parasitized! This is the Braconid wasp that parasitizes the caterpillar.

32. List the various symbiotic relationships Zombie snails Reef Symbiosis

33. Complex Symbiotic Relationships Zombie Ants Parasitic Wasps Be able to discuss the interactions of this complex symbiotic system.

34. Impacts of Climate Change on the Smoky Mountains PBL – Problem Based Learning –Your group is going to research a selected topic as we go throughout the Ecology Unit. –The topics are listed on the next slide –Look over these with your group. –Mrs. Cruce will draw names to allow groups to choose their topic

35. Brook Trout – Why are they endangered? Red-cheeked Salamander – Why are they endangered? Hemlock and Fraser Fir Trees – What is happening to them? Reintroduction of the Elk in the Smokies – has it been successful? Migratory Songbirds and calcium limitations – What is happening to them? Indiana Bat – Why are they endangered? Carolina Northern Flying Squirrel – Why are they endangered? Spruce-Fir Moss Spider – Why do we care that they are endangered? Reintroduction of Smoky Madtoms – has it been successful? Reintroduction of Peregrine Falcons – has it been successful?

36. PBL Task #1 Use as many of the Ecology terms we just learned to discuss your topic with your team. Relate this discussion to the Smoky Mountains and climate change as best you can. Pay attention to ground-level ozone and acid rain as you do your research. Here are some things I am looking for: –What has happened to their population numbers? –What about their community? –Think about their niche in their habitat…is their niche and/or habitat still present or have they had to find a new one? –Did they formerly have a symbiotic relationship with other organisms? If so, describe the relationship and please explain any changes that may have occurred since climate change has affected the Smokies.

37. PBL Task #1 –The next 2 bullets are answered according to the type of organism you have chosen: Heterotrophs: Tell me about their nutritional relationships…which type of heterotroph are they? Discuss their main food source and what may have happened to that population. Autotrophs: If you have an autotroph, what is happening to their population right now? Is it declining or rising? Give reasons why. –Give me any other information you feel is important to this point.

38. PBL Task #1 - continued Type this information into a presentation document….it can be a google presentation, a Prezi or something else that your group chooses. I would recommend that you use some type of sharing software so that you will be able to work on it at your respective homes. Use reliable internet sources and be sure to copy and paste the links into your document.

39. Quick Review Identify Similarities and Differences in a population, a community and an ecosystem. Give 1 example each of mutualism, commensalism, and parasitism.

40. Nutritional Relationships Autotrophs – make their own food (plants) –Also called producers

41. Nutritional Relationships Heterotrophs –eat autotrophs and other organisms –Also called consumers –Examples are animals, fungi, protists, and bacteria Types of Heterotrophs: –Herbivores eat plants –Carnivores eat animals –Predators »hunt –Scavengers »feed on animals they haven’t killed –Omnivores eat plants and animals

42. Didinium eating Paramecia

43. Energy Flow Relationships Producers – plants (autotrophs) Consumers – animals (heterotrophs) Primary – eat producers Secondary – eat primary consumers Tertiary – eat producers and primary consumers Decomposers –Break down dead organisms (bacteria and fungi)

44. See if you and your group members can answer the questions on the following slides. The answers are listed on the slide after each set of questions.
