1. As you come in Turn in Article Analysis on front table Complete “Question/Materials Needed” sheet for Group Research Project –We can use this to assess what materials we have/need & what materials you may have to supply for your project

2. Quiz Put notes away 10-15 min to take quiz Turn over/cover when finished

3. Today’s Objectives Explore examples of adaptation & convergent evolution in the greenhouse Develop ecological questions Practice writing proposals Apply statistical knowledge to proposed research questions Practice presentation skills

4. Goals of a Proposal In writing, describe in detail –What research you plan to do –What you hope to learn –Why it’s important

5. Components of a Proposal (for today) See page 30 Ecological Question Hypothesis Prediction(s) Reasoning for hypothesis Expected data *** Planned statistical test *** (add to pg 30)

7. Adaptation Heritable characteristic that improves organism’s fitness (survival & reproduction) Schemske et al.

8. Adaptation Any heritable characteristic of an organism that improves its ability to survive and reproduce in its environment. Also used to describe the process of genetic change within a population, as influenced by natural selection.

9. Adaptation ≠ Acclimation Acclimation –individual changes over short period of time to survive better in environment –Ex: shed winter fur in summer Adaptation –a population evolves to be better suited to its environment via natural selection & genetic change over multiple generations –Ex: evolution of cryptic coloring to avoid predation flickr

10. Natural Selection Selection acts on phenotypes –If brown beetles are less visible to predators than green beetles –Then brown beetles will be more likely to survive & reproduce Evidence is seen in populations over generations

12. Ecology & Evolution are interconnected Ecology –study of interactions between organisms and their environments Adaptation –An evolved characteristic of an organism that improves its fitness in its environment Thus, adaptations are both ecological & evolutionary

13. Rainforest Ecology Light competition Lots of rain –Promotes fungal growth High biodiversity Adaptations include –Epiphytes, vines, leaf morphologies

14. Desert Ecology Water limited Temperature extremes Adaptations include –CAM, annual life cycle, water storage

15. Today’s Activities Use worksheet (pg 134) to tour greenhouse & identify different adaptations Find examples of 10 adaptations on sheet Use most interesting to design your question Return to lab –develop proposals & presentations

16. Proposals & Presentations Proposal (at least 1 pg) See pgs 144-145 –Question- Experimental design –Hypothesis- Prediction graph(s) –Prediction(s)- Statistics to use –Reasoning for hypothesis (Demo GoogleDocs & Etherpad) Presentation –Explain all components of proposal

17. Presentations Class should ask 3+ questions after each proposal (participation grade) Also discuss the following: If you were on a granting committee, –Why might you consider funding this project? –What other information would you want before deciding to fund it? Ecological & Evolutionary connections of topic

18. Announcements Next week = in-class work day Write proposal for group research project Bring laptop if you have one Read over pgs 144-145 for proposal info
