Computer-Based Tools for Teaching about Robert Axelrod’s Prisoner’s Dilemma Tournaments

Posted 20 Jan 2011 / 7

In a recent posting I discussed the book The Evolution of Cooperation by Robert Axelrod [1, 2]. The book chronicles Axelrod’s work in the 1980’s to understand the dynamics of the Iterated Prisoner’s Dilemma (IPD), which is perhaps the most well-known of game theory constructs. Axelrod’s work is important because it points out how rich Read More

“The Evolution of Cooperation” by Robert Axelrod

Posted 10 Jan 2011 / 0

I just finished reading Robert Axelrod’s seminal book entitled The Evolution of Cooperation. Although I had read a lot about Axelrod’s work and am quite familiar with the body of literature that it inspired, I had never actually read his book cover to cover. Going in, my expectation was of finding a rather primitive treatment Read More

In the Light of Evolution V: Cooperation (January 7th)

Posted 07 Jan 2011 / 0

John C. Avise [1, 2] started off the colloquium by giving a very brief introduction to the In the Light of Evolution series, highlighting much of the history I discussed in my preview. Peter Nonacs “Insect Societies: Pinnacles of Cooperation” Nonacs began his talk by giving it an additional subtitle: “peaks of runaway niceness”. His Read More

Saving Puffins, One Clip at a Time

Posted 15 Dec 2010 / 0

There’s an interesting article in a recent issue of the Chronicle of Higher Education entitled “A Path for Puffins“. The article discusses the campaign to help eradicate an invasive plant species from a somewhat-remote Scottish Island that is home to thousands of puffins. The puffin population was showing steady decline on the island, and an Read More

Mirsky on Poop in Space

Posted 29 Nov 2010 / 0

As an ecologist one of my biggest pet peeves is the way that manned space travel is treated in the mainstream media, both fictional and non-fictional. Without going deeply into the details, suffice it to say that our dependence on ecosystem services makes manned space travel of any appreciable duration or distance completely unrealistic. Of Read More

Using Ecological Footprints to Teach Sustainability

Posted 27 Nov 2010 / 1

Technically- and traditionally-speaking, an ecology course should not really deal too much with policy. A strict definition of ecology should limit the topic to the study of the interaction between organisms and their environment, and for decades now that has meant looking at how non-human animals and other organisms constitute ecosystems. Discussions of policy, economics, Read More

Reclaiming a Rigorous Definition of “Sustainability”

Posted 18 Nov 2010 / 0

The latest issue of Frontiers in Ecology and the Environment features a great guest editorial by David N. Laband and David B. South entitled “Walking the talk on sustainability”. In this short piece, Laband and South make a point that is brought to light far too infrequently: that we use the word “sustainable” in a Read More

Are Eco-labels an Effective Tool for Conservation?

Posted 17 Nov 2010 / 0

On of the things that I like about the Ecological Society of America’s “accessible” journal Frontiers in Ecology and the Environment is that it always contains an eclectic mix of articles. The November 2010 issue contains an article entitled “Strategic tradeoffs for wildlife-friendly eco-labels” that you just would not see in most academic journals. Authored Read More

Official video of the International Year of Biodiversity 2010

Posted 17 Nov 2010 / 0

One of my current Ecology students brought this video, produced by the United Nations, to my attention today: I think what is most fascinating about this video is the premise upon which it is built. Using the video screen to represent some sort of biodiversity catalog console, it envisions a time when future generations have Read More

Delayed Development and Human Evolution

Posted 16 Nov 2010 / 0

For hundreds of thousands of years, Homo neanderthalensis was the dominant hominid species of Europe and the Middle East. Then, somewhere in the range of 80,000 to 50,000 years ago, modern humans (Homo sapiens) expanded out of Africa and came in contact with the Neanderthals. Although there is some evidence of limited interbreeding between Homo Read More
