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.
