Announcements
I have posted the hand-outs for the next lecture. Please print them as I will NOT bring any to class.
I have also posted the link to the YOUTUBE video I mentioned in class (see below). Take a minute to see it.
Textbook and readings
There is no official text book. Instead, you will be assigned readings from the primary literature to go with the lectures. The reading is required, and the material covered in the paper is part of the lecture material, and hence subject to questions on the midterm and final.
Two books that are relevant and available in the library: Shaw & Goffinet (2000) Bryophyte Biology or its latest version Goffinet & Shaw (2008) and Nash (Lichen Biology). If you are interested, you can buy them. I can also order them at a discount (although it may come out close to what you get on line with major distributors).
Grade
The final grade is calculated based on your lecture grade (60%; i.e., 5% assignment(s), 20% midterm and 35% - cumulative (I'll explain) - final) and lab (40%; i.e., 15% project and 25% final). No curves, but chances to make up points if needed!

- Watch This: movie of bryophyte gametes
"Whitish smoke in the movie are small droplets containing smreps (deliberate misspelling of word for male gametes).
The smreps in the droplets are still un-motile. When touch the
water, they begin to swim. In our experiments, misting with water is
trigger of the explosion. If antheridia were mature, the explosion
begin within few minutes. The event continued about for 10 min.
Intense light for video recording also seems to accelerate the
phenomenon. Each antheridia is deeply sunk in a cavity of
antheridiophore and there is a very small pore on the top of each
cavity. Swollen cells of surrounding tissue might cause the pressure
force. Cavers (1903) and Muggoch & Walton (1942) also discussed about the mechanism, but, I think no one examined about the detail mechanism of the phenomenon.
In Hiroshima, the season of mreps dispersal is Spring (April to May).
In our field observation, we detected many airborne smreps in the
sunny day after rain shower.
I do not have detail data about how many species of liverworts have
airborne mreps. At least, Asian species of Conocephalum (C.
japonicum) do in the same manner." M. Shimamura

- Not surprisingly, internet sites devoted to the biology of bryophytes and lichens are "abundant", well let's say that sites dedicated to bryophytes exist! Some may hold information that is relevant to this class. One example is Bryophyte Ecology maintained by Dr. Janice Glime
. I will look for more. You may want to consult the list maintained by Jessica Budke, another graduate student in my lab, and her moss blog entitled Moss Plants and more.

downloads require password; best viewed in Adobe Reader (some problems with the MAC "Preview" program).
The syllabus is subject to change. You will get papers assigned one lecture and maybe one week ahead. Check the site frequently.
