Announcements (NEW ONES POSTED)
Some comments or recommendations:
Assignment 1 is now posted.
1. Take the assignments seriously; this includes working on your presentation of the life cycle. The cleanliness of the assignment reflects on how serious you took the assignment. I value clean documents.Assignments are worth 5% of your final grade.
2. Answer the question: in many cases an answer was provided, yet, often it fails to actually answer the question. For example: Justify why the sporangium is diploid. Common answer: because it produces haploid spores. Well, a gametophyte produces haploid sperm-cells and eggs, does that make it diploid? No. A sporangium is diploid because it arises through mitotic division from a diploid zygote. That is all.
Here is a short document summarizing phylogenetic terms that you should know. Read this and let me know if you have any questions. This is not covered in class but considered to be covered by one of your earlier classes.
LABORATORY ATTENDANCE: you are required to attend the labs. If you miss 3 labs or more, without a written excuse you will automatically fail the class.
LECTURE FINAL: You can download the study guide for the final here.
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: Introduction to Bryophytes by A. Vanderpoorten & B. Goffinet (2009) (here the link to the book, http://www.cambridge.org/gb/knowledge/isbn/item2326970/?site_locale=en_GB). This book is the most appropriate external reference for the class. Other books are Shaw & Goffinet (2000) Bryophyte Biology or its latest version Goffinet & Shaw (2008) and Nash (Lichen Biology, here the link to Amazon http://www.amazon.com/Lichen-Biology-Thomas-H-Nash/dp/0521459745). 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%: midterm and - in part cumulative - final each worth 25%, and each of the two assignments worth 5%) and lab (40%: 30% final based on hands-on labs, and 5% of your paper presentation, 2.5% for summaries and 2.5% for participation in discussions).
Links
- 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 antheridium 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.
- Mosses in the news: Single peat moss plant 'conquered America'.
- Watch this short video, highlighting aspects of the biology of mosses, a great complement to the lectures.
NOTES UPLOADEDHere is the book chapter that I mentioned in class that you must read to complement your lecture notes. The figures must be downloaded separately:

Schedule
Notes:
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.
