Z chromosome divergence, polymorphism and relative effective population size in a genus of lekking birds
Sara J. Oyler-McCance, Robert S. Cornman, Kenneth L. Jones, Jennifer A. Fike
2015, Heredity (115) 452-459
Sex chromosomes contribute disproportionately to species boundaries as they diverge faster than autosomes and often have reduced diversity. Their hemizygous nature contributes to faster divergence and reduced diversity, as do some types of selection. In birds, other factors (mating system and bottlenecks) can further decrease the effective population size of...

Brady A. Ziegler, Jennifer T. McGuire, Isabelle M. Cozzarelli
2015, Environmental Science & Technology (49) 13179-13189
Biodegradation of organic matter, including petroleum-based fuels and biofuels, can create undesired secondary water-quality effects. Trace elements, especially arsenic (As), have strong adsorption affinities for Fe(III) (oxyhydr)-oxides and can be released to groundwater during Fe-reducing biodegradation. We investigated the mobilization of naturally occurring As, cobalt (Co), chromium (Cr), and nickel...
