TL;DR: It is found that genes that were retained as duplicates after the teleost-specific whole-genome duplication 320 million years ago were not more likely to be retained after the Ss4R, and that the duplicate retention was not influenced to a great extent by the nature of the predicted protein interactions of the gene products.

TL;DR: The genome sequence of Atlantic cod is presented, showing evidence for complex thermal adaptations in its haemoglobin gene cluster and an unusual immune architecture compared to other sequenced vertebrates.

TL;DR: Together, the habituation of the stress response shown in both species did not eliminate the growth difference found in the repeatedly stressed fish versus the control fish, and the lower growth performance of Eurasian perch compared to rainbow trout could partly be due to the increased energy consumption in the more stress responsive Eurasia perch.

TL;DR: It is shown that MHC II is missing in the entire Gadiformes lineage and thus was lost once in their common ancestor, and an association between high MHC I copy number and elevated speciation rates using trait-dependent diversification models is identified.

TL;DR: The data suggest that adaptive responses to the environmental conditions in the Baltic Sea may contribute to a strong and effective reproductive barrier, and that Baltic cod can be viewed as an example of ongoing speciation.
