Erica and Kelsie were awarded a grant from Jefferson County to study three species of cottontail rabbit in the Denver area. This grant is a collaboration with Dr. John Demboski at the Denver Muesum of Nature and Science. Kelsie is ready to get to the DMNS and get started!

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
