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

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!

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

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

ESA 2012 Thursday afternoon talks

Posted 10 Aug 2012 / 0

I spent Thursday afternoon once again hustling from one talk to another, with Organized Oral Session #47 (Universal Senescence? New Theories and Experimental Approaches Across the Tree of Life) being my primary focus. The writings of George C. Williams and his ingenious antagonistic pleiotropy hypothesis explaining aging have always fascinated me. Like a lot of Read More

HOME, a documentary about the impacted Biosphere

Posted 18 Sep 2011 / 0

I just watched the video Home, a production of Yann Arthus-Bertrand and his Good Planet Foundation. Composed solely of high-quality panoramic images intensified by a soaring new-age soundtrack, the film provides viewers with a fairly comprehensive overview of the earth’s ecosystems and the challenges to the future health of these ecosystems posed by human industry.
