Since I am not an ecologist, when I teach the ecology lecture I 'go by the book' and trust that the textbook will be reasonably accurate. But now, perhaps I should rethink the way I teach about ecological succession...What do my ecological readers think?

I just got the teaching schedule for Spring, so I decided to follow up on last week's post by putting, under the fold, a series of short posts I wrote when I taught the last time, musing about teaching in general and teaching biology to adults in particular. These are really a running commentary…
I see that Doug at Nanoscale Views has fond memories of the hit show The Mechanical Universe. If you have never seen this show, it is quite excellent (even if old).
Perhaps the best thing about The Mechanical Universe is that it might be the best that traditional lecturing can provide. Oh, I know…
The first thing I think when I read the title to this post is, "Man, that's a long friggen title, and it's not at all catchy." The next thing I think is, "I thought I said I wasn't going to write about ecology." Well, I actually wrote:
"I am in no way, shape, or form an organismal biologist nor…
Inside Higher Ed has an op-ed piece up urging faculty to abandon textbooks:
Here's a statement with which everyone can agree: College instructors cannot assume that students come to their classes in possession of basic knowledge. Now here's one sure to generate some controversy: In many cases…
Well, this has sort of thing has really been known for decades. Indeed in the early 20th century, Clements was competing with Gleason, who argued for a more random view of things. The Gleasonian view has been in vogue for years now.
I agree with Steve. Also, most ecologists recognize stochastic processes like recruitment in thinking about succession. I'm biased towards the marine world, but I think you might find salt marsh and rocky intertidal succession useful examples for class. There's a lot of discussion on how different forces, such as competition, facilitation, and physical stress, interact to influence successional patterns. This book is a good reference.
