Mapping genomes and navigating behavior for wildlife conservation

Virginia Aida wrote this post as a final project for Stacy Krueger-Hadfield’s Science Communication course at the University of Alabama at Birmingham. She is currently evaluating a potential pharmacotherapy in traumatic brain injury and anticipates graduating with her MS in summer 2017.  Although she … Continue reading

Molting on the molecular level: how blue crabs become soft-shell crabs

Megan Roegner wrote this post as a final project for Stacy Krueger-Hadfield’s Science Communication course at the University of Alabama at Birmingham. Megan spent her early years in Cape Town, South Africa playing in the tidal pools along the coast and developing … Continue reading

The not so singular process of hybridization

What, if anything, are hybrids? Zach Gompert and Alex Buerkle ask this question in a special issue in Evolutionary Applications. Hybrids occur when unrelated individuals mate, but how distant do the taxa need to be to constitute a cross? The varied … Continue reading

To the final estuaries

For the final stop on our Japanese sampling leg, we ventured to the most populous metropolitan area in the world. Tokyo was known as Edo (江戸), or estuary, until it became the imperial capital in 1868. An apt location to end our field expedition … Continue reading

Genomics of domestication in chicken and cattle

Two recent studies attempt to understand the process of adaptive evolution in domestication and artificial selection by characterizing (a) sweeps, and their association with phenotypes in extant hybrid lines (Sheng et al. 2015), and (b) phylogenomic position of an extinct … Continue reading

Small mammalian genomics of adaptation

While large mammals have had their day on our blog, two recent studies on small mammals reveal the genetics of size evolution in island mice, and differential introgression of mitochondrial and nuclear genomes in chipmunks – steps towards understanding the … Continue reading

The unforeseen genomic consequences of domestication

When a desired genome is selected for propagation, all mutations, beneficial, neutral, or deleterious, shift in frequency, and this sometimes can have unforeseen consequences. Natural selection takes the good with the bad. Beneficial and harmful mutations combine to provide a net … Continue reading
