THE SEPARATE HOUR

DIALOGUE 12:  EXCAVATES AND EUGLENOIDS.  We will introduce the DOMAIN EUKARYA and present the Endosymbiosis Theory of its origin.  Come prepared with all appropriate taxonomies and data sheets for the SUPERGROUP EXCAVATA and its kingdoms EUEXCAVATAE and DISCICRISTAE.  Be prepared to discuss all of the associated phyla.    Be able to discuss the salient or synapomorphic characters that serve to define each phylum.  In order for this to be a rewarding exchange, you must have read all of the indicated web materials.  Also, read the following in preparation for the dialogue:

• Holt. E Pluribus Unum

THE COMMON HOUR

GAME 5. Please come prepared with information from last week. The categories will be TAXONOMY, ANATOMY/STRUCTURE, PHYLOGENY/LIFE HISTORY.  As before, much of this information comes from the data sheets, Holt (2006), Darwin (1859), cultures, slides, and preserved specimens from the last week of class.   We will provide taxonomies of the appropriate groups.  You may use nothing else.  We anticipate that this game will last only half of the time allotted to it.  We will take questions about any of the information from last week prior to the game.

THE SEPARATE HOUR

ACTIVITY 12. EXCAVATES AND EUGLENOIDS.  Look at the following cultures, specimens and slides.  Access sheets on the Euexcavatae and the Discicristatae  to help guide you in your observations.

1. Examine the gut contents of termites (Zootermopsis), and find the Parabasalids and Metamonads that inhabit them.
2. Trichonympha: wm slide
3. Trichomonas:  wm slide.
4. Chilomastix: wm slide of trophozoites
5. Giardia: wm slides of trophozoites & cysts.
6. Trypanosoma: blood smear slides of several species.
7. Crithidia: living
8. Leishmania: spleen smear slide.
9. Euglena: living, wm slide.
10. Peranema: living
11. Naegleria: wm slide in brain tissue.
12. Examine the petri plates and hay infusions.  

THE COMMON HOUR

DIALOGUE 13.  CRYPTOMONADS, HAPTOMONADS, AND CHROMALVEOLATA I.  We will begin looking at taxa within the Supergroup CHROMALVEOLATA.  This time we will concentrate on the kingdoms EUKARYOMONADAE and ALVEOLATAE. Come prepared to discuss and ask questions about the following phyla:  Cryptomonada, Haptomonada, Ciliata, and Dinoflagellata.   In order for this to be a rewarding exchange, you must have read all of the indicated web materials.  In addition, read the following in preparation for the dialogue:

• Holt. Killer Algae
• Holt. Night Lights
• Origin of Species, Chapter 6

Concepts and Terms for Dialogue 10:  Please access the appropriate concepts and terms for the taxa covered today through the front pages of the kingdoms EUKARYOMONADAE and ALVEOLATAE.  Any of these terms could be used in the Game next Monday.

FRIDAY 22 FEBRUARY

THE COMMON HOUR

UNKNOWN 3:  Print out a copy of the Alga Data Sheet and bring it with you to class on Friday.  Look at the organism and complete the algal data sheet before you attempt the key.  Also, be sure to to include a drawing that indicates at least two key characters of the genus.

Your first draft of the Animal-Bacteria Project must be posted in \\hopper\ppf before 4 p.m.
