DU delegates visited the University of Western Australia. The highlight of the trip was kangaroos!
Spermatogenesis and the Evolution of Mammalian Sex Chromosomes
Erica L. Larson, Emily E.K. Kopania, and Jeffrey M. Good
Developmental constraint and sexual conflict shape the evolution of hetero- morphic sex chromosomes. These contrasting forces are perhaps strongest during spermatogenesis in species with XY males. In this review, we consider how the unique regulatory environment and selective pressures of spermato- genesis interact to impact sex chromosome evolution in mammals. We explore how each developmental phase of spermatogenesis influences sex chromo- some gene content, structure, and rate of molecular evolution, and how these attributes may contribute to speciation. We argue that a developmental context is fundamental to understanding sex chromosome evolution and that an evolutionary perspective can shed new light on our understanding of sperm development. PAPER
The Murphy, Tinghitella and Larson Labs have been sampling clover across Denver as part of the Global Urban Evolution Project. We had great help from Veronica Huizar and Gui Zheng, who are participating in the University of Denver STEM Student Research Initiative. Check out Veronica and Gui's blogs about their summer research experience!

Guild of Rocky Mountain Ecologists and Evolutionary Biologists (GREEBs) met at the University of Colorado Mountain Research Station for a great weekend of talks, posters and great conversations with local researchers.
I am thrilled to be joining the faculty at the University of Denver, Department of Biological Sciences as an assistant professor in September, 2017.
