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

EnviroAtlas is now live, publicly available

Posted 30 May 2014 / 0

For the past couple of years I have been playing around with a really cool tool called EnviroAtlas, a project of the U.S. Environmental Protection Agency. This past semester I created two classroom activities that use EnviroAtlas, implementing them for the first time in my Ecology for Architects course. The EnviroAtlas tool was in beta-testing Read More

Interesting numbers on the sustainability (or lack thereof) of the aviation industry

Posted 20 Feb 2014 / 0

Air Transport Action Group “Facts & Figures” I recognize that these statistics are being presented by an industry advocacy group, so they should be taken with some skepticism (I don’t have the time to fact-check them). But they are interesting, and damning enough of air transport (while also accenting our very strong dependence on this Read More

Concentrated factory farming of livestock massively alters the phosphorus cycle

Posted 25 Jan 2014 / 0

NPR Morning Edition “How Mass-Produced Meat Turned Phosphorus Into Pollution” This short feature provides a clear example of how human agricultural practices massively modify nutrient cycles, decoupling what used to be inseparable: where animal feed is grown and where animals are raised. This separation means that we no longer have closed-loop agricultural systems. I would suggest Read More

Once considered clear, the line between ecological and evolutionary time scales is becoming more blurry

The Chronicle of Higher Education “What Darwin Got Wrong” Great article on the importance of better understanding rapid and/or fluctuating evolution! The number of applications to applied human issues is fascinating.

Scientific American “Tiny Plants” article provides a primer on the inter-relationship between ecological and evolutionary change

Posted 07 Jan 2014 / 0

I am always on the lookout for great popular science articles to assign to my students. What makes a popular science article great? Well, to start with it should address concepts that are core to my classes (admittedly, this definition of “greatness” is highly relative to what I decide is important to teach). Concept density Read More

US EPA’s EnviroAtlas project promises to give researchers, students new insights into the geography of ecosystem services

Posted 13 Aug 2013 / 0

At the 2012 Annual Meeting of the Ecological Society of America, I first learned about a really interesting initiative of the U.S. Environmental Protection Agency. The project –now dubbed EnviroAtlas — is dedicated to creating a free, interactive online tool for exploring the geography of ecosystem services. I had the opportunity to check out a beta version Read More

NPR piece suggests that economics are pushing us towards nutrient recycling

Posted 10 Apr 2013 / 0

NPR All Things Considered “Cities Turn Sewage Into ‘Black Gold’ For Local Farms” This is a really interesting piece because it suggests that the costs associated with properly disposing of human waste are beginning to incentivize municipalities to repurpose this waste as fertilizer. As this feature indicates, landfilling and (even worse) incineration have been in Read More

Fracking study retracted after the discovery of a massive conflict of interest

Posted 07 Dec 2012 / 0

All Things Considered “Positive Fracking Study Was Funded By Gas Company” 1.5 million dollars is a lot to receive from a corporation with interest in your research! Scientists can be bought, and transparency is the only thing that prevents profit-driven scientific fraud.
