Addressing incomplete lineage sorting and paralogy in the inference of uncertain salmonid phylogenetic relationships.

ABSTRACT: Recent and continued progress in the scale and sophistication of phylogenetic research has yielded substantial advances in knowledge of the tree of life; however, segments of that tree remain unresolved and continue to produce contradicting or unstable results. These poorly resolved relationships may be the product of methodological shortcomings or of an evolutionary history that did not generate the signal traits needed for its eventual reconstruction. Relationships within the euteleost fish family Salmonidae have proven challenging to resolve in molecular phylogenetics studies in part due to ancestral autopolyploidy contributing to conflicting gene trees. We examine a sequence capture dataset from salmonids and use alternative strategies to accommodate the effects of gene tree conflict b
