HOMEWORK ASSIGNMENT # 2 VERTEBRATE ZOOLOGY SPRING 2000 DR. CRONE

Topics: Cartilaginous fish, bony fish, and amphibians

distributed 2/8, due 2/29 at lecture time

If HVCC is closed at lecture time on 2/29, then the assignment is due Thursday, 3/2 at lecture time

Please type your answers to these questions. I expect well-constructed sentences, paragraphs, outlines, and/or diagrams. If you are using course handouts and/or the textbook extensively for your answer, please document appropriately, as well if you are using outside sources. I will grade the entire assignment for a 20 point grade. Answers will be graded for accuracy, completeness, grammar, and appropriateness of citations. The answers should be available in the textbook, the lab manual, or other referenced resources, if not necessarily in the assigned readings!

I will be happy to go over rough drafts with you during office hours or an appointment.

Possible answers will be put on reserve at the library, the Biology Study Center, AMZ 219, and my website after the homeworks have been collected (late Thursday afternoon 3/2).

GOOD LUCK!

  1. You're off sport fishing in the Caribbean, when there's a strong tug on your line. After a long fight, you haul in a fish you've never seen before. Before you use your knife to gut it, what types of external features would you look for to indicate that it's a cartilaginous and not a bony fish?
  2. The Pacific salmon has a definite impact on the economies of Washington, British Columbia, and Alaska. What is the life cycle of the salmon? What human impacts interfere with this pattern?
  3. A major feature of the amphibians and other tetrapods are limbs. What are the major limb bones off of both the pectoral and pelvic girdles? What are examples of fossil evidence in the evolution of limbs from fins? What were (presumably) major influences on this pattern of change?
