The effects of ice keels on the upper ocean are examined using a combination of
turbulence measurements and output from a large-eddy simulation (LES) model. Two
cases are examined, one during the winter when the under-ice boundary layer is relatively
deep (~20 m) and near the freezing point and a...

Morphologically divergent ecotypes arise in fish populations on postglacial time scales, and resource polymorphisms
are often invoked to explain their origin. However, genetic recombination can constrain the ability of divergent selection to produce
reproductive isolation in sympatry. Recombination breaks up favorable combinations of traits (”adaptive suites”) if individual
traits are...
