Melanie Massey defends her extraordinary MSc thesis!! (and immediately begins a PhD in evo devo at Dalhousie U.!). Well done Melanie.
The Original Bug Shirt Company (www.bugshirt.com) generously contributes to our long-term studies in Algonquin Park. The bugs are bad up here, and the Rollinson group greatly appreciates your contribution!
Njal is appointed to the Amphibians and Reptiles Species Specialist Subcommittee of COSEWIC

December 16th, 2016 Melanie Massey wins UofT's TAoftheyearaward- congratsMelanie!
September 1st, 2016 Hollis Dahn wins a prestigious Connaught Scholarship. Congrats Hollis!
September 11th, 2015 New paper "Persistent directional selection on body size and a resolution to the paradox of stasis" is covered on the eco-evo blog.
August 15th, 2014 This entry is a plug for the excellent programs offered byNIMBioS. Last week Njal attended a NIMBioS tutorial on evolutionary quantitative genetics at the University of Tennessee. The workshop was amazing, both in terms of content and instruction. Njal strongly encourage all evolutionary ecologists to check out theNIMBioSwebsite, and the ongoing tutorials they offer.
