Preview of the 2012 Ecological Society of America annual meeting in Portland, Oregon

Posted 02 Aug 2012 / 0

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.

This year I am proud to be returning to the Ecological Society of America annual meeting in Portland, Oregon. I missed last year’s meeting and I am excited to be overwhelmed by all the amazing scholarship that is on display at these meetings. I generally present talks at meetings, but this year I decided to do 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

Are the population dynamics of Dupont’s lark dictated by multilevel selective pressures?

Posted 25 Jun 2012 / 0

A fascinating new paper published this week in the journal PLoS One demonstrates how selection acting at least three different levels produces distinct selective pressures that shape the song behavior of male Dupont’s lark (Chersophilus duponti) in the Ebro Valley of northwestern Spain. Authored by Paola Laiolo and José Ramón Obeso and entitled “Multilevel Selection Read More

Mutualistic fungus transfers nitrogen from parasitized insects to its plant host

Posted 22 Jun 2012 / 0

Science “Endophytic Insect-Parasitic Fungi Translocate Nitrogen Directly from Insects to Plants” What I find fascinating about this story is how a fungus that parasitizes one species can use that ability to form a mutualism with a plant host. I wonder whether there is a value-added feature of this parasitism: are the parasitized insects potential parasites Read More

Who is the bigger bioterrorist, man or nature?

Posted 21 Jun 2012 / 0

Nature “Engineering H5N1 avian influenza viruses to study human adaptation” I think that the most interesting idea expressed by this article is: In considering the threat of bioterrorism or accidental release of genetically engineered viruses, it is worth remembering that nature is the ultimate bioterrorist. There is so much in this single statement, so many Read More
