Textbook and readings
There is no official text book. Instead, you will be assigned readings from the primary literature to go with the lectures. This material is considered part of the lecture material and must be read for the midterm and exam .
Announcements (NEW ONE ADDED APRIL 30)
- FINAL exam info:
A) we will post an assignment on this site on Monday; you must complete the assignment and bring it to the final; the assignment will consist in drawing a phylogenetic tree; the instructions will be explicit. You will be asked a few questions and use your tree to complete the assignment
B) I posted new links to all my lectures (BG) from the second half of the semester.
C) Here is
a study guide to the final. I will answer questions you have about it until Tuesday 5PM (included); i.e., I will be unable to answer questions submitted after that time.
- Watch This: Moss helps chart the conquest of land by plants
- Learn more about the Rhynie Chert at http://www.abdn.ac.uk/rhynie/intro.htm</br>
- Reading for Thursday April 1 class. This paper (: Strotheretal2004SM.pdf) will be discussed in class, in preparation of Dr. Strother's seminar which you have to attend and summarize. You should read this for Thursday and come prepared to ask questions and talk about it. After you have read through it once, go over the abstract and assess whether you got the main points.</br>
- I have made a pdf of several figures from a paper by Hemsley that may help you understand the difference between monads, dyads, etc... See : Hemsley spore figures.pdf
- I (BG) have posted two papers pertaining to the last two lectures. The short paper by Taylor provides a summary (dating from 1982 but still valid) on the reproductive biology of early land plants. The paper of Soltis is longer but you only must read 3-9 and 16-20. Make sure you read both of these papers for the final (I have not and will not add additional papers for the other lectures I covered).</br>
- Please read this copy of : assignment 4: a) it provides an excellent summary of the seminar (which is considered lecture material) and b) it may provide a reference and help you compose your summary of Dr. Pryer's seminar.
Schedule (updated April 13)

- 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
