Grass on a Pedestal

Posted 08 May 2015 / 0

Around this time of year at Pratt a great variety of student sculpture work sprouts up on the grounds. I thought that this one was particularly interesting. I could not find out what its title was or who made it, but I thought that it nicely captured our relationship to grass, especially on the Pratt Read More

The costly nature of wind pollination

Posted 05 May 2015 / 2

It is once again that time of year, the time when trees that rely on wind pollination dump a really absurd amount of pollen into the air. The surfaces of outdoor objects become covered in a layer of yellow dust that is shockingly visible to the naked eye. When it rains, run-off nearly glows yellow 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

My ecological footprint for 2014-2015

Posted 06 Apr 2015 / 0

Every year in my ecology courses I have my students complete an ecological footprint analysis of their own lifestyle and the lifestyle of an older relative. I have been asking my students to do these for each of the eight years that I have taught at Pratt Institute, so I have accumulated a lot of Read More

Envirolutions brings bottle transformation to Green Week 2015

Posted 03 Apr 2015 / 0

There have been a lot of great projects done by the club over these years, and some of the best have been centered on Pratt’s Green Week, an annual on-campus celebration of sustainability.

How stupid professorial attitudes towards Wikipedia are making students less savvy

Posted 03 Mar 2015 / 1

Recently I have come to realize that (too) many professors have a profound disdain for Wikipedia. Although I sometimes encounter this disdain directly, most of the time I see contempt for Wikipedia reflected through my students. These stupid professorial attitudes about Wikipedia tend to cast a pretty unflattering reflection off of their students. It is Read More

PCB Bioaccumulation and Polar Bear Penises

Posted 20 Feb 2015 / 0

National Geographic News “Is Pollution Weakening Polar Bears’ Ability to Mate?” This sounds like fodder for a late-night television laugh line, but this is a pretty scary example of how bioaccumulation of toxins can have important conservation consequences. From a conservation perspective, there is nothing worse than a ubiquitous pollutant reducing the ability of a Read More
