Excited to share this work, out today in MBE! In polar fishes, we found that antifreeze protein genes expanded in copy number at low temperatures and contracted in the deep sea, highlighting a role of depth and pressure in AFP evolution.

Oxygen supersaturation has been reported to protect aquatic animals from heat waves. We tested this in a large collaborative experiment on many species of fish and crustaceans. Our new paper in @plosbiology.org shows that the effect of hyperoxia on thermal tolerance is negligible. Unfortunately.

Duplication–translocation played an unexpectedly large role in the associations we found between gene copy number, temperature, and depth. Variation in copy number at tandem arrays formed by inter- and intrachromosomal translocations drove environmental gradients in AFP copy number.
