Great Field Trip! Thank you to everyone for contributions large and small! If you have pictures that you would be willing to share with the group, please send them as a jpg attachment to Kevin at

Here’s what you need to know about the midterm (Wednesday) and plant identification (Tuesday) exams next week. (We answered a few questions from individual students during the field trip and wanted to make sure everyone had the same information.)

MIDTERM: For the midterm, you should review your notes on lectures, readings, labs, and field trips. For the history / philosophy section, make sure to review the discussion questions for each week’s lecture reading. The lecture / seminar material for week 5 on plant associations (Clements/Gleason) and scientific revolutions will be on the midterm. (I would recommend reading them in the order that they appear as attachments in the Moodle site.) Kevin will hand out a final list of potential essay questions on Monday that should look familiar if you have read the material and considered the discussion questions; there will be time during the lab period on Tuesday to work with other students to develop answers to these essay questions. Remember that you can have one page of notes for the midterm.

PLANT IDENTIFICATION: Final list of species for plant identification exam (Tuesday, Oct. 27). We “pruned” the list of required species down to 25. You should be able to identify the following species based on a sample (e.g. branch and leaves) and produce the scientific name from memory. The plant identification exam will be on Tuesday, Oct. 27. The page numbers next to the plants are from Pojar and Mackinnon (revised edition).
