1. Marine Biology MAR111 Prof. Nancy Black Lecture: Tu & Th 6:00 – 7:25 pm Lab: Tu 7:40 – 9:40 pm

2. Books:  Marine Biology, 9th edition, Peter Castro and Michael E. Huber. McGraw-Hill Higher Education. 2013. (recent older editions are OK)  Laboratory and Field Investigations in Marine Life, 10th edition, James Sumich and Gordon Dudley. Jones & Bartlett Publishers. 2011. (optional)

3. Grading: 1000 points total: Lecture = 60% 3 lecture midterm exams (200 points each) drop lowest midterm exam grade = 400 points cumulative final exam = 200 points Lab = 40% midterm quiz = 50 pts practical final exam = 100 pts 10 lab assignments X 10 pts each (drop lowest lab) = 90 pts 2 short research papers (25 pts each) = 50 pts 2 field trips X 50 pts each = 100 pts overall attendance / participation = 10 pts

4. How to get a good grade:  Attend class and lab  Print the powerpoint lectures before class and take notes on them  Read the book  Study for the exams (seriously)  Turn in assignments on time  Do the extra credit work  Students who attend, participate, show interest, and/or show improvement will get a bump up a half grade at end if on the borderline

5. Printing Powerpoint Slides 2-3 per vertical page (3 gives lines for notes) 4 per horizontal page write in margins

13. Tools of Marine Biology – Scientific Method  Observe, describe  Coral reef

14. Tools of Marine Biology – Scientific Method  Observe, describe  Stony corals  Animal polyps have algae cells inside

15. Tools of Marine Biology – Scientific Method  Observe, describe  Corals once green and brown are now white  Water temperatures were 30°C (86°F) or more for several weeks http://www.york.ac.uk/depts/biol/units/symbiosis/images/coralbleach.jpg

16. Tools of Marine Biology – Scientific Method  Ask questions  Why did the corals turn white?  Did the warm temperatures cause the problem? Pollution? Salinity changes? UV?  Is it permanent or will the coral recover?

17. Tools of Marine Biology – Scientific Method  Choose one question to address, then create a hypothesis  The prolonged warm water temperatures caused the “bleaching” http://appserv.pace.edu/emplibrary/thermometer.gif AFP/Queensland University/File/Ove Hoegh-Guidberg

18. Tools of Marine Biology – Scientific Method  Conduct a controlled experiment to test the hypothesis  Collect some identical corals  Place some in normal temperature water and others in warmer water http://www.aqob.com.au/images/product/detail/72rosscoralbleachingtanks.jpg

19. Tools of Marine Biology – Scientific Method  Experiment results, statistics  Corals in lab held in the warmer water “bleached” after several weeks while those in the control water did not

20. Tools of Marine Biology – Scientific Method  If confirmed, then more tests of the hypothesis  Experiment must be repeatable  Test other species, temperatures, time frames  If not, then test an alternative hypothesis

21. Tools of Marine Biology – Scientific Method  Theory  After the hypothesis has passed extensive testing and is accepted as true, it may be considered a theory  Explanation supported by evidence  Beware of misuse (scientific theory is not a guess, that’s a hypothesis)
