Evolution 2014: Aphids protect themselves from parasitoids by harboring a bacteria whose viral parasite is toxic

Posted 21 Jun 2014 / 0

Andrew Smith of Drexel University spoke about a four-species interaction that could best be described as “my symbiont’s enemy is my parasitoid’s toxic enemy” scenario. Aphids can avoid being parasitized by a parasitoid wasp if they harbor particular bacterial strains. What’s interesting is that the bacteria don’t directly confer resistance to the parasitoid: instead, it is the Read More

Evolution 2014: Day 0

Posted 20 Jun 2014 / 0

I started off this year’s Evolution meeting early. The conference is — at its core —  a four-day affair. But the days leading into the “official” start on Friday evening feature larger workshops aimed at building skills. I chose to attend the Experiencing Evolution workshop. Here’s what this session promised: Evolution is a key biological concept, Read More

Evolution 2014: Evolution of cooperation in the high school classroom? You bet!

Posted 20 Jun 2014 / 0

Will Ratcliff presented an absolutely amazing set of laboratories that explore the evolution of multicellularity (http://www.snowflakeyeastlab.com/). They can be done with high school or college students, and allow students to see the benefits of cooperation and the action of multilevel selection in a few weeks’ worth of laboratory work. Really impressive classroom activity design!

EnviroAtlas is now live, publicly available

Posted 30 May 2014 / 0

For the past couple of years I have been playing around with a really cool tool called EnviroAtlas, a project of the U.S. Environmental Protection Agency. This past semester I created two classroom activities that use EnviroAtlas, implementing them for the first time in my Ecology for Architects course. The EnviroAtlas tool was in beta-testing Read More

John Oliver holds first “balanced” climate debate on television

Posted 30 May 2014 / 0

Very nicely done! The monologue is great, but then the “performance” of the balanced climate change debate is really what drives home the point here. Don’t watch networks that present false “debates”.

Our review paper on Late Pleistocene Extinction Modeling published in QRB!

Posted 21 May 2014 / 0

I am proud to announce that a paper on which I am co-author, “A review and synthesis of late Pleistocene extinction modeling: Progress delayed by mismatches between ecological realism, interpretation, and methodological transparency“, has been published in the June 2014 issue of The Quarterly Review of Biology. The paper looks at the history of modeling aimed Read More

Is “nest parasitism” really “nest mutualism”?

Posted 20 May 2014 / 0

NPR All Things Considered “This Freeloading Bird Brings Help — And The Help Smells Gross” It is hard to believe that feeding an entire extra non-offspring would be in the self-interest of a bird, but as this short points out, costs and benefits are always environment-specific. In this case, the “parasitic” effect of having to raise Read More

There’s No Such Thing as Qualitative Sustainability

Posted 16 Apr 2014 / 1

Thinking green is just not enough It was one of those classic moments where the irony just seemed too severe to be unplanned. I was riding my bike to work when I passed a parked vehicle and noticed a remarkable bumper sticker. I still regret not taking out my phone and snapping a picture; because Read More

New glacial maximum on Mount ARC provides definitive evidence that Pratt’s sustainability efforts are working

Posted 01 Apr 2014 / 1

Pratt Institute’s Mount ARC, part of the central Brooklyn range, has been a hotbed of climatological research. A unique geological feature within the mostly-flat borough of Brooklyn, Mount ARC rises above Pratt Institute’s majestic campus, looming over this community of creative makers like a stern warning from good old Mother Nature herself. Mount ARC’s two Read More

I receive funding to initiate the WmD Project

Posted 06 Mar 2014 / 2

It seemed like a proposal with a dim chance of being funded, but on a bizarre whim of inspiration I decided to apply for a small bit of money so I could initiate a new creative venture that I am calling the WmD Project. It turns out that Pratt’s Faculty Development Fund has a bit Read More
