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

Megan Frederickson shares the wonder of ant cooperation with Toronto Library patrons

Toronto Public Library/University of Toronto Exploring Evolution series “The Evolution of Cooperation: Ant-Plant Associations in Peru” We need more scientists out there explaining the wonders of evolutionary biology!

Does anthropogenic change make natives into invaders?

Posted 19 Sep 2012 / 0

Frontiers in Ecology and the Environment “Native invaders – challenges for science, management, policy, and society” This article makes an important point: the “alien” criteria for invasives is a bit arbitrary when the problem with invasives is their ability to explode in population and inordinately impact other populations. Perhaps we need to re-think the way Read More

Rachel Carson still under attack for bringing her values to bear on her science

Posted 17 Sep 2012 / 0

Slate “Rachel Carson Didn’t Kill Millions of Africans: How the 50-year-old campaign against Silent Spring still distorts environmental debates” There is a lot of interesting stuff here, including a fascinating view into how scientific findings get processed by the public (both left and right leaning). The ad hominem attacks on Carson are interesting because they seem 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

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

Steven Pinker makes it clear that he is not a “group selectionist”

Posted 26 Jun 2012 / 5

Frequently I feel like I am listening to an early 2000’s George W. Bush speech when the ‘opponents of group selection’ step up to the podium. Seemingly, you are either “with us or against us” when it comes to considering selection acting at a level above the individual. As someone who is open to thinking 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

“Creatures of Light: Nature’s Bioluminescence” exhibit at the American Museum on Natural History

Posted 19 Jun 2012 / 0

Today I had the pleasure of accompanying my daughter’s fourth grade class to the “Creatures of Light: Nature’s Bioluminescence” exhibit at the American Museum of Natural History. Beyond making sure that all students returned home safely, I was also interested in how this exhibit explained bioluminescence as an evolved adaptation. When I teach Evolution, one Read More
