INVERTEBRATE ZOOLOGY
FALL 1999 MWF 10:00-10:50
LIBRARY 154
Text: Biology of the Invertebrates by Pechenick (3rd or 4th
ed; indicated by initials BOI); library reservations will also be used to supplement
material; students must also access the class webpage at www.newcollege.usf.edu/gilchrist/
and refer to the course name at the homepage.
Office hours Tue 9:30-11; others by appointment ONLY phone 2-4377 email gilchris@sar.usf.edu ; Tracy Rosebrock will be
available 7-9 pm on Monday and Wednesdays in Han 36 for assistance as well
Invertebrate Zoology is a three module sequence which allows students to explore most
of the animal world. Although traditional courses in this subject look to morphological
and phylogenetic relations, we will go beyond this view to include behavior and ecology of
the organisms as well. For the first module, we will study what are considered
multicellular organisms. This will include examination of the Porifera, Placozoa,
Cnidaria, Ctenophora, Platyhelminthes, Gnathostomulida and Mesozoans, Nermertina,
Nematoda, Rotifera and their relatives, and the Annelida. The second module will focus on
the Nematomorpha, Acanthocephala, Priapulida, Mollusca, Arthropoda, Hemichordata, and
Protochordata. (the third module of the sequence will occur in Fall 00 and will examine
the Protozoa)
Evaluation will rest on a project and reading journal, two quizzes, and a final
project. The project and reading journal will include results, discussions, and
conclusions from in class projects as well as a critical
review* of 4 articles from the primary literature (DO NOT USE THE SAME ARTICLES FOR
CRITICAL REVIEWS AND READING JOURNAL). Guidelines for reviews will be given in class
and can be found on the class webpage. Quizzes will emphasize broad concepts and
terminology. The final project will be a poster or oral presentation focused on a group or
species studied during the term. Each should include an introduction, discussion and
bibliography.
Below is a tentative schedule for topics. Some changes may be made relative to class
interest/progress.

Platyhelminthes Gnathostomulida and Mesozoans |
ch 7, 8 BOI; lib 1 ; see www.tauchen.de/homepage/flatworms/
for a photogallery of flatworms (be patient, if you expand from the thumbnail pictures it
takes a few minutes.) Thought questions: 1. Compare and contrast the life
cycle of the rhombozoans with the digenean flatworms. 2. Compare and contrast
the acoelomate body plan in the vermiform groups (discuss the variations). 3.
Discuss the role of cilia in the Platyhelminthes. I will not collect these
questions, but they may help to study for the quiz on October 1. Quiz will be open
book and open notes. |
