Deep Look on nutrient transport by salmon

Posted 09 Oct 2017 / 0

I have taught about the importance of nutrient transport by salmon in my Ecology course before, using an old Scientific American article. But this video is amazing. The footage of the salmon spawning and of blowfly maggots devouring a salmon carcass are phenomenal. A great teaching tool for talking about how community ecology drives nutrient Read More

EcoMotion studios celebrates Robert Paine’s Pisaster experiments

Posted 06 Oct 2015 / 0

Back at the Evolution 2014 meeting I encountered the great “Drift” animated short, which I still use in my evolution course. Well the producers of that short have formed ECOmotion Studios, and they have made a bunch more videos in honor of the Ecological Society of America‘s centennial. This one is a fun “spoken word” jam Read More

New article in Science provides a comprehensive overview and update on Yellowstone National Park

Posted 24 Apr 2015 / 0

Since I began teaching Ecology at Pratt, I have used the re-introduction of wolves to Yellowstone as the cornerstone case study of my community ecology lessons. Using material originally developed by my colleague Damon Chaky for the Ecology for Architects course, I ask my students to use ecological theory to explain some of the changes that Read More

Understanding the cascading effect of carnivore loss… before we lose all the carnivores

Posted 25 Jan 2014 / 0

NPR Morning Edition “When Big Carnivores Go Down, Even Vegetarians Take The Hit” Science “Status and Ecological Effects of the World’s Largest Carnivores” Both of these articles are great for introducing the idea of trophic cascades as well as how trophic inefficiency implies that large predators require large ranges containing abundant prey.
