Codweb: Whole-genome sequencing uncovers extensive reticulations fueling adaptation among Atlantic, Arctic, and Pacific gadids

Codweb: Whole-genome sequencing uncovers extensive reticulations fueling adaptation among Atlantic, Arctic, and Pacific gadids   Evolution, invasion, admixture, and introgression among the Gadids. The Arctic and Polar cod is an outgroup of the Gadids, which are marine fish supporting most important fisheries in the North Atlantic and North Pacific. A few million years ago an […]

Extensive structural variation between ecotypes of Atlantic cod, Gadus morhua, revealed with linked-read sequencing and optical mapping

Katrín Halldórsdóttir and Einar Árnason. 2019.  Extensive structural variation between ecotypes of Atlantic cod, Gadus morhua, revealed with linked-read sequencing and optical mapping. Poster presented at Speciation: Gordon Research Conference, Ventura, California, USA. March 10--15, 2019.   Several “stocks” are recognized for fisheries management among Atlantic cod. The stocks are populations that differ from each other […]

Identifying loci under positive selection in complex population histories

Alba Refoyo-Martínez, Rute R. da Fonseca, Katrín Halldórsdóttir, Einar Árnason, Thomas Mailund, Fernando Racimo https://doi.org/10.1101/453092 Abstract Detailed modeling of a species' history is of prime importance for understanding how natural selection operates over time. Most methods designed to detect positive selection along sequenced genomes, however, use simplified representations of past histories as null models of […]
