1. Week 2 Ms. Darlak

2. Warm-up 05/20 What is a possible explanation for this picture?

4. Agenda 05/20 Habitat and Niche Notes p.8 Practice p. 6 & 7 Symbiotic Relationships p. 9

5. Habitat vs Niche Lets see what Reginald the Red Wolf has to say. http://www.youtube.com/watch?v=2L6N2diE8jc

6. Habitat vs. Niche p.8 Habitat: Where and Why? Niche: How? What? When? Read page 6-7, Underline when text is describing niche, circle the text that describes an animals habitat.

7. Warm-up 05/21 What is the Habitat of the Ants? (Circle) What is its niche? (Underline)

8. Agenda 05/21 Habitat vs Niche Check Symbiotic Relationships p.9 Yellowstone Organism Hypothesis

9. What is the niche? set of conditions within which an organism can maintain a viable population multi-dimensional with as many dimensions as their are limiting conditions temperature light intensity okay salinity ecological niche

10. Physical Niche: depends on physical (abiotic) conditions, general niche. Niche without competition. Realized niche depends on biotic as well as abiotic conditions. Niche because of competition.

11. growth rate Location in intertidal zone lowhighmiddle Chthamalus alone Balanus alone Physical Niche What, when, why……..…. without competition. Balanus fundamental niche Chthamalus fundamental niche

12. growth rate Location in intertidal zone lowhighmiddle Realized niche is with biotic (competition and predation) and abiotic recourses. Balanus realized niche Chthamalu s realized niche Balanus and Chthamalus

13. Streams with only Planaria species A Streams with only Planaria species B Streams with both Planaria species

14. Symbiotic Relationships p.9 “living together” Commensalism Mutualism Parasitism Predation Competition

15. Commensalism relatively unaffected Commensalism means "at table together". One organism consumes the unused food of another. Some examples: The remora and the shark. Some species of barnacles Many of the bacteria living in our large intestine. Epiphytes

16. Mutualism Both benefit Relationships in which each species benefits. Examples: Pollinators and Flowers Clownfish and Anemone Lichen - fungus & algae

17. One organism gains at the expense of another Examples: Tapeworm Mosquitoes Parasitoid wasps Parasitism one gains, other loses

18. Predation +/- Interaction where a predator (an organism that is hunting) feeds on its prey, the organism that is attacked

19. Competition +/-, -/+ Interaction between two or more organisms, or groups of organisms, that use a common resource in short supply. There can be competition between members of the same species and competition between members of different species Examples: Lions and Hyenas

20. What type of Relationship? Mutualism

21. What type of Relationship? Commensalism Epiphyte Plant

22. What type of Relationship? Parasitism

23. Predation

24. What type of Relationship? Mutualism

25. What type of Relationship? Commensalism

26. Parasitism

28. Warm-up 05/22 List 2 different symbiotic relationships and give an example of each.

29. Agenda 05/21 Yellowstone Organism Hypothesis Lessons from the Wolf Record observations mentioned in the Article List words you don’t understand.

30. Write a hypothesis on how you think reintroduction of the wolf is going to affect one of the following organisms. American Bison Black Bears Grizzly Bears Bighorn Sheep Bobcats Coyotes Elk Moose Beaver Mountain Goats Mountain Lions Deer (Mule or White-tailed) Cutthroat trout Voles Squirrel species Rabbit species River Otter Ravens Mink Cottonwood Trees Willow Shrubs Songbird species (warblers, flycatchers, etc) Bald Eagles Red Fox

31. Lessons from the Wolf p.10-11

32. Read Article Record observations mentioned in the Article List words you don’t understand. What benefits from the wolf? What does not? Why reintroduce the wolf? Was your hypothesis supported?

33. Warm-up 05/23 What type of symbiotic relationship do you have with your parents? mutualism, parasitism, commensalism, competition, predation Explain why?

34. Agenda 05/23 Intra vs Interspecific Competition Computer Lab A Due Friday Lessons from the Wolf Record observations mentioned in the Article List words you don’t understand.

35. Intraspecific vs Interspecific Intraspecific Interspecific competition within the same species. Owls competing among themselves for the same food source competition between two or more different species. Owls and hawks competing against each other for the same food source

36. Lessons from the Wolf p.10-11 Read Article Record observations mentioned in the Article List words you don’t understand. What benefits from the wolf? What does not? Why reintroduce the wolf? Was your hypothesis supported?

37. Computer Lab A Portfolio see requirements on p.3 p. 1-2 Habitat & Niche p.3 Relationships

38. Warm-up 05/24 Write down 5 observations from the article, Lessons from the Wolf, from your homework on p.11.
