My review of “How Species Interact” published in Ecological Modelling

Posted 18 Aug 2012 / 1

My review of How Species Interact: Altering the Standard View of Trophic Ecology by Roger Arditi and Lev R. Ginzburg was just published in Ecological Modelling. You can also read the review here. Lev Ginzburg was my dissertation advisor, so clearly this review has to be seen as subjective; however, if you look at how strong Read More

ESA 2012 Overall Impressions

Posted 12 Aug 2012 / 0

What was the ‘big news’ at this year’s Ecological Society of America meeting? Given that this meeting is composed of so many different meetings running concurrently, this just might be an impossible question to answer fairly. But for me, this year’s meeting could be summarized as the ‘year of computational ecology’. At a great variety 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

ESA 2012 Workshop #8, Getting off the Ground with Individual-Based Modeling: A Primer for Instructors and Researchers

Posted 05 Aug 2012 / 0

I got off to a running start at this year’s Ecological Society of America (ESA) annual meeting with a workshop orchestrated by Steven Railsback and Volker Grimm. Entitled “Getting off the Ground with Individual-Based Modeling: A Primer for Instructors and Researchers“, the workshop was a practical introduction to the material provided in their new textbook Agent-Based Read More

I am off to another Ecological Society of America (ESA) meeting, my sixth and the society’s ninety-seventh. As I already covered in a previous post, I will be presenting a poster entitled “The Evolution of Sustainable Use, a flash-based classroom tool for teaching population biology and sustainable resource management” during the Tuesday afternoon poster session.

If your loners are truly loners they won’t punish, and cooperation thrives even in the presence of antisocial punishment

Posted 28 Jun 2012 / 1

Last summer I discussed a paper by Rand and Nowak that explored the dynamics of antisocial punishment in groups composed of cooperators, defectors, and loners playing a public goods game. In a conventional public goods game, at least some players must make a contribution in order to reap group reward. Cooperators make that contribution and Read More

Perhaps nestedness is just an artifact of ecological opportunity (and not stability)

Posted 27 Jun 2012 / 0

One of my chief interests is stability: I am curious about what allows for the persistence of genes, individuals, groups, species, and communities. This is a broad question and it may not have single, simple answer, but it is exciting to think that there may be ‘rules of stability’ in nature that might help us Read More
