Eco 101: Exponential Growth & Decay

Posted 27 Jan 2017 / 0

Different rates of positive and negative growth create different population trajectories over time In biology, a population is a group of organisms that belong to the same species and occupy a defined land area (or volume of air or water). These populations have the tendency to grow and shrink over time. This is because the rate at which members of Read More

My ecological footprint for 2016-2017

Posted 31 Oct 2016 / 0

It’s that time of year again. Once again I send my students in my Ecology course out to estimate their ecological footprints, so to show that I am holding myself to a similar standard — and to make sure to keep myself ecologically self-aware — I always make sure to make my own footprint public. This should Read More

The question is how — not whether — students use electronic devices in the classroom

Posted 14 Sep 2016 / 0

The Chronicle of Higher Education “No, Banning Laptops Is Not the Answer (And it’s just as pointless to condemn any ban on electronic devices in the classroom)” I appreciate this nuanced approach to technology use in the classroom, but I tend to lean towards the “any ban is counter-productive” perspective. I like the idea of being Read More

Announcing “Eco 101”, a series of blog posts on the basics of ecology

Posted 01 Feb 2016 / 0

After about three decades of people adding content non-stop to the free internet, you would figure that it would be relatively easy to find well-written, accurate articles on basic concepts in ecology. But Read More

Eco 101: Carrying Capacity

Posted 25 Jan 2016 / 0

Fundamentally, carrying capacity is a measure of the maximum density of a particular population How many organisms of a particular species can an area support? What determines this maximum population density? The answer to these questions is captured by the ecological concept of carrying capacity. The carrying capacity tells us how many organisms of a particular species Read More

How much impact can a set of free game theory infographics have?

Posted 02 Dec 2015 / 0

A few years ago, I worked with graphic designer Greg Riestenberg to come up with a series of infographic images designed to make several foundational game theory constructs easier to understand. Our approach was to take all the numbers out of the representations, using information design to highlight how the games work and how they differ from each Read More

W.W. Norton’s new InQuizitive partner to the Bergstrom and Dugatkin Evolution textbook

Posted 15 Oct 2015 / 0

W.W. Norton Company, the publisher of Carl Bergstrom and Lee Alan Dugatkin’s Evolution textbook, have released a demo version of a new learning tool called InQuizitive. This activity leads students through a series of questions designed to test their understanding of phylogenies as well as the rather bizarre and counter-intuitive jargon of phylogenetics. I played Read More

My new favorite concept mapping activity: depicting whole-system ecological flows

Posted 17 Jul 2015 / 0

Concept mapping is increasingly becoming an important part of my overall approach to teaching. I started out using it in my own research, and quickly realized how valuable it can be as a teaching tool. Because the only real goal of making a concept map is to explore and express understanding of a topic, concept Read More

Basic instructions for making effective concept maps using VUE

Posted 29 Sep 2014 / 0

For years now I have been guiding my students through a variety of concept mapping activities. Almost every one of my classes involves at least one concept mapping assignment, and I now require that proposals for a variety of term papers and projects be presented in concept map form. I also created this guide to Read More

My Evolution 2014 talk is on YouTube

Posted 17 Jul 2014 / 0

One nice thing that organizers of the Evolution 2014 conference did was to offer the opportunity for presenters to have their talk recorded and archived. These recorded talks now have their own Evolution 2014 YouTube Channel, and my talk is included in this collection: This was an experiment for this conference, and I think that it came Read More
