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

Production on marginal lands can meet only 25% of our biofuel mandates

Posted 17 Jan 2013 / 0

Nature “Bioenergy: Biofuel production on the margins” & “Sustainable bioenergy production from marginal lands in the US Midwest” This is fascinating, and provides further evidence that even the smartest biofuel production methods are not going to be enough to mitigate our energy demands. In order to really get off of fossil fuels, we need to find Read More

Lee Alan Dugatkin blesses Slate with a piece on Kropotkin

Posted 31 Oct 2012 / 0

Slate “The Russian Anarchist Prince Who Challenged Evolution” I really appreciate the fact that Dugatkin uses Kropotkin to bring to light that Darwinian evolution has been — even in the time and work of Darwin — a process that was imagined to involve both competition and cooperation. Only in recent times has evolution become synonymous Read More

National Geographic on the yartsa gunbu bubble

Posted 23 Aug 2012 / 0

National Geographic “Tibetan Gold” This story encapsulates a whole host of unsustainable human behaviors: First, we have people over-harvesting an ecological product in a manner that risks its collapse; Second, the over-harvesting is driven by a cultural superstition that has spread without any real basis in fact; and Third, the entire over-valuation of these parasite-infested-worms is Read More

ESA 2012 Symposium #23, Commodifying Nature: The Scientific Basis for Ecosystem Service Valuation in Environmental Decision Making

Posted 10 Aug 2012 / 0

Friday morning is a tough spot at an ESA meeting. It is the last day of a six-day conference, and there are only morning events, so many people evacuate before this final session. And for those who do drag themselves out of bed for sessions beginning at 8 am (perhaps, like me, for the sixth 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

The many ecotones of the Columbia Gorge

Posted 04 Aug 2012 / 0

Before heading over to spend six twelve-hour days in the Oregon Convention Center, I had the good fortune to go on a backpacking trip along the Eagle Creek, Pacific Crest, and Ruckel Creek trails in the Mount Hood Wilderness Area. Although I am far from being an expert in the nuances of biomes (and certainly Read More
