The labs will follow the syllabus outlined on the Biology of the Algae HuskyCT site. Lab handouts will be posted there 1-2 weeks ahead of the lab.
Not all, but most of the labs will likely take the full 3 hours they are scheduled for. FYI. <br>

We are going outside, so dress accordingly (including footware). <br>
 
Here are the handouts we will be using in the first lab: <br>
 
:{{pdf|http://hydrodictyon.eeb.uconn.edu/courses/greenplants/restricted/ocular%20micrometer%20handout.pdf}} ocular micrometer handout <br>
 
:{{pdf|http://hydrodictyon.eeb.uconn.edu/courses/greenplants/restricted/Lab1-2008.pdf}} handout for lab 1 <br>
 
  
===1st Field Trip - September 6th===
 
In spite of the weather threat, we've collected algae at Harkness Memorial State Park - yay! I will bring them to lab on Monday. We have extras for those who didn't come out with us, so everyone will be able to get a few specimens pressed. I WILL BE IN LAB FROM 1 PM (office hour). YOU CAN COME PRESS YOUR ALGAE THEN IF YOU ARE WORRIED YOU WON'T HAVE TIME DURING OR AFTER LAB. <br>
 
  
===Lab 2 - September 8th===
 
:{{pdf|http://hydrodictyon.eeb.uconn.edu/courses/greenplants/restricted/Lab2%263-terms%20to%20learn.pdf}}  Some terms you should look at before you go to lab on Monday <br>
 
:{{pdf|http://hydrodictyon.eeb.uconn.edu/courses/greenplants/restricted/Lab2%263-2008.pdf}} Handout for labs 2 and 3. This is the ''minimum'' you need to know for the upcoming quiz, including specified parts of the supplemental handouts I will bring to lab on Monday. There may be some optional material for you to look at, but you will not be quizzed on that. <br>
 
  
===Lab 3 - September 15th===
 
We will be using the handouts from last time. Don't forget to bring them to lab. This lab may not be as busy as the previous one, but take this as an opportunity to look at the specimens and slides again if you need to. There is a quiz coming up the following Monday. <br>
 
  
===Lab 4 - September 22nd===
 
Lab Quiz 1: I will ask you to identify several herbarium specimens (mostly to genus) and place them in the correct class and/or order, identify structures on permanent slides and determine what stage of the life cycle they represent. I will NOT ask you to draw life cycles of red algae, but you should be familiar with them enough to answer fairly detailed questions about them.
 
<br>
 
Handout for this and next lab to be posted soon...<br>
 
We will go over life cycles (yay!) of brown algae, so bring your handout from Wednesday's lecture.

If you'd like to explore the amazing world of algal diversity, here's a couple of links I personally find cool. <br>

[http://www.tolweb.org/tree/ The Tree of Life] is a nice one to start with. Can you locate algae on the tree of life? Are they in a single place, all neatly together? Well, look and see.<br>

Here you can find information on some of the morphologically most impressive algae - diatoms and desmids.
More about desmids here.
