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

If sloths endure costs to maintain closed-loop agricultural systems, why can’t we?

Posted 05 Feb 2014 / 0

The New York Times “The Sloth’s Busy Inner Life” This is a great story about how paradoxical behaviors can be understood through appreciating mutualisms. If you don’t understand the benefits of algae to sloths and sloths to algae,  you can’t understand this behavior. But you also need to understand how sloths directly benefit moths and how Read More

What happens when a landscape ecologist takes on urban ecology

Posted 29 Jan 2014 / 0

What’s so cool about the work that Eric Sanderson is describing is that it really amounts to doing historical research using an ecological forensics approach. The idea of mapping out “probable areas” of different populations — including humans — using mapped data is pretty smart. It is amazing how humans have transformed Manhattan. Thanks to Read More

Sweet Fern Productions puts Alfred Russel Wallace to paper

Posted 26 Jan 2014 / 0

Sweet Fern Productions “The Animated Life of A.R. Wallace” I loved the Sweet Fern video on whale fall, but this is even more valuable as a historical account of Wallace’s life. I really like the way that this video depicts natural selection! Great way of showing differential survival as Wallace might have seen it!

Was Teilhard de Chardin the real inventor of an evolutionary approach to culture?

Posted 26 Jan 2014 / 0

On Being “Teilhard de Chardin on The “Planetary Mind” and Our Spiritual Evolution” We often give credit to Richard Dawkins — who is undeniably the inventor of the term “memetics” — for introducing an evolutionary approach to cultural change. But as this piece makes clear, de Chardin was already thinking on far more large scales about 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.

Why socially-progressive scientists should not make bets…

Posted 25 Jan 2014 / 0

NPR Morning Edition “A Bet, Five Metals And The Future Of The Planet” This is an excellent piece that encapsulates the argument between “population pessimists” and “technological optimists”, an argument that seems to have been won by the technologists. It is frustrating how much damage has been done by people like Paul Ehrlich. His overconfidence Read More

Cod gone on Cape Cod

Posted 25 Jan 2014 / 0

NPR Morning Edition “Why The Cod On Cape Cod Now Comes From Iceland” It is fascinating how “cultural” the alteration of this fishery turns out to be. Somehow “Cape Dogfish” just does not have the same ring.

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

Posted 25 Jan 2014 / 0

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.
