The Hohenlohe lab is part of the
Department of Biological
Sciences and the Institute for Bioinformatics and
Evolutionary Studies (IBEST)
at the University of Idaho. Our research
focuses on the genomic architecture of evolving populations.
Congratulations to Cody Wiench, who received an Undergraduate
Research Award from the Department of Biological Sciences to work
in the lab for the summer. Cody will be working on
estimating the G matrix in experimental yeast populations.
Hybrids between introduced rainbow trout and native westslope
cutthroat trout generally have lower fitness than the parental
species. Nonetheless, we identified a small set of loci at
which rainbow trout alleles have introgressed rapidly into
hybridized populations and now occur at significantly higher
frequency than the overall level of admixture. See the

theory and speciation. See Andrew Hendry's commentary here,

analyzing the dimensionality of sexual isolation in Timema
stick insects, Patrik Nosil and I detected a novel signature of
reinforcement -- parapatry appears to increase the dimensionality
of traits and preferences involved in mate choice and sexual
isolation. Check out the paper in early view here,

In 2011 we used RAD
sequencing to identify thousands of candidate diagnostic SNPs to
differentiate westslope cutthroat and rainbow trout. Now in
a new paper in Molecular Ecology Resources, we show a high rate of
validation for high-throughput SNP assays based on a subset of
these candidates. Early view is available here. [Mar
