water relations and fall leaf color
Jon Monroe
Greetings and Happy New Year. I hope everyone is having a good start to
the new year and is enjoying the spam-free newsgroup! Activity on
plant-ed has been rather light in recent months so I urge you to
remember to use it. Please post your plant-related questions, answers,
ideas, job ads, and/or links to teaching activities you have developed
and wish to share. If you are new to the group please have a look at
our charter so you know what we are about:
http://www.bio.net/charters/plant-ed. If you want to encourage a
colleague to subscribe, send this url to them:
http://csm.jmu.edu/biology/monroejd/planted.html.
Here are two items to get us rolling.
1. Each year in Plant Phys when I teach water relations some students
ask for practice problems and each year I fail to get around to it.
Does anyone have a set of problems they would be willing to share to get
me started?
2. Last fall I was hiking in the nearby hills during peak leaf color
season and I caught myself staring at red maple leaves that were yellow
and red and peppered with brown hypersensitive spots. I started
hypothesizing about why they looked as they did and thought it might
make an interesting problem for students (to stare and hypothesize...).
So I collected a bunch of leaves, took digital photos and placed them on
my course website on a page describing the assignment
http://csm.jmu.edu/biology/courses/bio455_555/acerleaf/acerleaf.html.
Feel free to look at it, use it if you wish, and give me feedback on it
if you think it can be improved.
Best wishes,
Jon
