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.

Now legal, Northern California’s pot farms join the rest of agriculture in impacting water supply

Posted 14 Jan 2014 / 0

NPR The Salt “California’s Pot Farms Could Leave Salmon Runs Truly Smoked” It is funny because as marijuana becomes legalized it joins tobacco and coffee as a potentially high-impact, low-necessity agricultural product. And I know there are a lot of cigarette smokers, coffee fiends, and potheads taking exception to that last sentence.

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

With all we know, we still know too little to reliably re-engineer ecosystems

Posted 06 Sep 2013 / 0

NPR Morning Edition “Saving One Species At The Expense Of Another” There are a number of really important points made by this nice short. The first is that scientists — even when acting carefully on the best available evidence and theory — can still fail to produce desired outcomes. The second is that modifying ecological communities Read More

Cooperative child-rearing pays dividends for ruffed lemurs, irrespective of kinship

Posted 23 Aug 2013 / 0

Mongabay News “The evolution of cooperation: communal nests are best for ruffed lemurs” Behavioral Ecology and Sociobiology “Communal nesting, kinship, and maternal success in a social primate” What I find particularly interesting about these findings is that they appear to show that kinship — if a factor at all — might well be a byproduct Read More

National Geographic “The Short Happy Life of a Serengeti Lion”

Posted 23 Aug 2013 / 0

National Geographic “The Short Happy Life of a Serengeti Lion” This article provides a great overview of the kind of work that Craig Packer’s research group does in the Serengeti to understand the social behavior of lions. There is valuable information here on why lions are social (unlike other large cats), why lions must cooperate, 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

Isabella Rossellini’s Green Porno

Posted 21 Jul 2013 / 0

I have been preparing for next semester’s Evolution of Sex course by looking for new media that might help my students. I just spent a few enjoyable hours checking out Isabella Rossellini’s Green Porno series, produced by the Sundance Channel. I have been aware of Rossellini’s rather interesting foray into the world of animal sex and reproduction for awhile Read More
