Erin McKenney of Duke University talked about three lemur species with different diets: a frugivore (fruit-eater), a generalist, and a folivore (leaf-eater). Not surprisingly their gut morphologies and passing times vary with their diet, but McKenney showed that they also have unique trajectories as infants are colonized by symbiotic bacteria of different types.

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

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

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!

Susan Singer, who is part of the National Science Foundation’s Undergraduate Biology Education division, talked about funding opportunities for faculty who want to create pedagogical materials at small undergraduate institutions. She pointed out that the NSF‘s Research Coordination Networks program funds projects that are sited at multiple institutions, including those in undergraduate biology education (“RCN-UBE“). This kind of Read More

Julie Noor’s classroom activity in Drosophila breeding points out a really great “best practice” for any data collection in undergraduate laboratory exercises: if you ask students to first interpret only the data they collected, then allow them to interpret the aggregated data of the whole class, you can allow them to see the importance of sample size.

Julie Noor of Duke University shows how a very simple classroom experiment in fly breeding to the F3 generation can force students to answer the following question in the affirmative: “Have you ever seen evolution actually occurring?” It is powerful when students are able to report that they have seen “evolution in action”.

Jim Costa of the Highlands Biological Station points out that Darwin’s scientific explorations in his own backyard were as profoundly important to his theories as his voyage on the H.M.S. Beagle.

After landing at Raleigh-Durham airport today I am ready for Evolution 2014! It has been four years since I last attended the annual meeting that brings together members of the Society for the Study of Evolution (SSE), the Society of Systematic Biologists (SSB), and the American Society of Naturalists (ASN). I do not always get the chance to attend this conference, so Read More

When I was in graduate school working towards my doctorate, we were required to take “comprehensive exams” to stay in the program and qualify for candidacy. This made a lot of sense: I was lucky to be in a program whose required courses created a very strong background in my disciplines, and the comprehensive exams Read More
