Marine BiologyMAR111

Prof. Nancy Black

Lecture: Tu & Th 6:00 – 7:25 pm

Lab: Tu 7:40 – 9:40 pm


Marine biology mar111

  • 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 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


Marine biology mar111

  • 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

    • Behavior

    • Physiology

    • Cellular and molecular biology

    • Evolution

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

    • $$$$$$ ($20 trillion/yr!)

Tools of Marine Biology – Scientific Method

  • Observe, describe

    • Coral reef


Marine biology mar111

Tools of Marine Biology – Scientific Method

  • Observe, describe

    • Stony corals

    • Animal polyps have algae cells inside


Marine biology mar111

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

http://www.york.ac.uk/depts/biol/units/symbiosis/images/coralbleach.jpg


Marine biology mar111

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?


Marine biology mar111

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


Marine biology mar111

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


Marine biology mar111

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


Marine biology mar111

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


Marine biology mar111

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)
