Marine BiologyMAR111Prof. Nancy Black

Lecture: Tu & Th 6:00 7:25 pmLab: Tu 7:40 9:40 pm

Books:

Marine Biology, 8th edition, Peter Castro and Michael E. Huber. McGraw-Hill Higher Education. 2010. (recent older editions are OK)

Laboratory and Field Investigations in Marine Life, 10th edition, James Sumich and Gordon Dudley. Jones & Bartlett Publishers. 2011. (optional)

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 pointscumulative final exam = 200 points

Lab = 40%mid-term quiz = 50 ptspractical final exam = 100 pts9 lab assignments X 10 pts each = 90 pts2 short research papers (25 pts each) = 50 pts2 field trips X 50 pts each = 100 ptsoverall attendance / participation = 10 pts

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

Printing Powerpoint Slides3 per vertical page with lines for notes4 per horizontal pagewrite in margins

Tools of Marine Biology Scientific Method Observe, describe Coral reef

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

Tools of Marine Biology Scientific Method Observe, describe Corals once green and brown are now white Water temperatures were 30C or more for several weekshttp://www.york.ac.uk/depts/biol/units/symbiosis/images/coralbleach.jpg

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?

Tools of Marine Biology Scientific Method Choose one question to address, then create a hypothesis The prolonged warm water temperatures caused the bleachinghttp://appserv.pace.edu/emplibrary/thermometer.gifAFP/Queensland University/File/Ove Hoegh-Guidberg

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 waterhttp://www.aqob.com.au/images/product/detail/72rosscoralbleachingtanks.jpg

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

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

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, thats a hypothesis)
