ECOmotion Studios on Huffaker’s crazy experiments to make prey and predators coexist

Posted 06 Oct 2015 / 0

Here’s the last of four ECOmotion Studios animated shorts celebrating the Ecological Society of America’s centennial. This one’s a bit thin in my humble opinion. It captures the essentials of Huffaker’s really odd experiments (I am always struck by what extents Huffaker had to go to stabilize predator and prey populations), but mostly uses the narrative Read More

ECOmotion Studios on Hairston Smith Slobodkin and why the earth is green

Posted 06 Oct 2015 / 0

Here’s another fun and informative video from ECOmotion Studios. I thought that it was interesting how this short discussed the connection between decomposers and the eventual supply of oil, although I wonder if many viewers will gain enough information from this short video to fully understand this idea. The basic ideas behind Hairston-Smith-Slobodkin (HSS) are 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

Urban Wildlife Podcast on Cats and Coyotes

Posted 20 Sep 2015 / 0

Urban Wildlife Podcast “Episode 4: Cats and Coyotes” What I really enjoyed about this particular episode of the Urban Wildlife Podcast was the interaction between topics covered. The effects of both cats and coyotes are still largely unknown, even as both animals are fairly common in urban areas. Domesticated cats are pretty easy to track Read More

WmD Episode #00002 has been released

Posted 07 Aug 2015 / 0

It took me a lot longer than I would have wished, but I have released the second episode of WmD’s video blog: You can see this episode in its ‘native habitat’ here. The first season of WmD is dedicated to the “big questions in ecology and evolution“. This episode, “Keep on keeping on… until you 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

Evolution beyond adaptation: a critical step for evolutionary theory

Posted 04 Jul 2015 / 0

The July 2015 issue of Trends in Ecology & Evolution features a really important review article entitled “Selection on stability across ecological scales“. The paper embraces the idea that the stability properties of ecological systems dictate the configuration of extant social groups, interacting species pairs, and overall ecological communities. Lev Ginzburg, my Ph.D. advisor, has Read More

Zoonosis, Ebola, and the Elusive Reservoir Host

Posted 24 Jun 2015 / 0

There’s a really interesting article in the upcoming (July 2015) issue of National Geographic entitled “Stalking a Killer“. Using the most recent outbreak of Ebola in West Africa as a case study, the article looks at the nature of a variety of unusual and rare diseases caused by filoviruses. Ebola is not a virus that 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

Evolution 2014: Day 1

Posted 21 Jun 2014 / 0

My first session of the day was spent entirely in a Symbiosis session. I am fascinated by symbiosis, particularly mutualistic symbiosis, so I am always looking for cool new stories to help illustrate the concept for my students. This session featured a lot of talks on microbial symbionts, which are also of interest to me. The Read More
