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, 8th edition, Peter Castro and Michael E. Huber. McGraw-Hill Higher Education (recent older editions are OK)
Laboratory and Field Investigations in Marine Life, 10th edition, James Sumich and Gordon Dudley. Jones & Bartlett Publishers (optional)

3. Grading: 1000 points total, I will curve final grades up if necessary
Lecture = 60%
3 lecture exams (200 points each)
drop lowest exam grade = 400 points
cumulative final exam = 200 points
Lab = 40%
mid-term quiz = 50 pts
practical final exam = 100 pts
9 lab assignments X 10 pts each = 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
3 per vertical page
with lines for notes
4 per horizontal page
write in margins

6. The study of the organisms that live in the sea
Marine Biology
The study of the organisms that live in the sea

7. Marine Biology A subset of Biology Has subdisciplines: Taxonomy
Ecology
Behavior
Physiology
Cellular and molecular biology
Evolution

8. Marine Biology A subset of Oceanography: Biological Chemical Physical

9. Marine Biology Why is it important?
71% of the earth’s surface is water
Oxygen, global ecosystem
Disease, attacks, damage
Food, medicine, raw materials
Recreation, tourism

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

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

21. Tools of Marine Biology – Scientific Method
Observe, describe
Corals once green and brown are now white
Water temperatures were 30°C or more for several weeks

22. 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?

23. Tools of Marine Biology – Scientific Method
Choose one question to address, then create a hypothesis
The prolonged warm water temperatures caused the “bleaching”
AFP/Queensland University/File/Ove Hoegh-Guidberg

24. 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

25. 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

26. 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

27. 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)
