Lectures beyond this point not yet updated for 2013

Powerpoints for the remaining lectures (and the corresponding assigned original papers in Nature or Science) will be available on the WyoWeb course file site

Go to Lecture 34  (24-Apr-13)  TBA  (this is an older population genetics lecture, which I may not cover this year)

3-May-13 possibly an in-class review of material since Exam 2. 

Final exam is WEDNESDAY 8-May-13 8:00 to 10:00 in BC 138 (our regular classroom)

I will try to post "nearly final" Powerpoints ahead of scheduled lectures.
I will often revise the Powerpoints after I give a lecture, so that it more closely reflects what I actually covered in class. 
Look for a "revised dd-mmm-yy" message so that you can tell whether anything you want to print out is the "latest version".

A note on navigating the web pages:

Figures, Equations and Required Readings are labeled in a "chapter-like" manner, with each lecture as the equivalent of a chapter.  That is, Lecture 1's web page will be "Chapter 1".  All Figures in that web page will be numbered Fig. 1.1, 1.2, ...1.n for the n Figures it includes.  The same will be true for Equations (numbers for which will be toward the right-hand margin).  I will try to hot link most references to Figures or Equations WITHIN a web page, but may not do so BETWEEN web pages.  That is, a reference to Eqn 1.1 in the 2nd web page ("Chapter 2") might require you to jot that number down and surf back later.  The hot links will be the standard underline format.  I will have links between all the web pages that I design for this course.  I may even put in some external links. Come see me if you need help on browsing the web pages.  Please let us know, also, if you find typos, pages that won't print properly, or other glitches.
Reading numbers may change if the lecture schedule shifts -- the updated list of number will be reposted occasionally both on the web and in the WyoWebs Readings folders.

Finding required readings:

You can download various required readings (in PDF format) and other files by going to WyoWeb.

1) Go to the WyoWeb page (by going to the UW home page and clicking the WyoWeb link)
2) Log in (your campus username and password)
3) Click the "Student" tab near the top of the page
4) Near the upper left of the resulting window you should see a box that says "My Courses."
Click on the blue words "For Spring 2013 courses, click here"
5) In the next page, the biggest area should be labeled "Courses I'm taking"
6) Hit the "Population Ecology" link
7) On the Population Ecology page, the box near the upper left will have a link called "Files."  Click that. 
8) That will bring up a window that has a list of subfolders.  Choices include "Powerpoints", “Required readings ” (set of required readings including those from the Gotelli text), “Suggested” (recommended, but not required) and “Handouts” (most of these will be given out as hard copies in class).  Click the subfolders (make the arrow/triangle go from pointing sideways to pointing down, otherwise you won't be able to see or access the files) then click the file links to download them.

Required readings are listed by Lecture number and date corresponding to when I cover that material in class, just before the ".pdf" extension.  The lecture number is equivalent to the Lecture number in the syllabus.
