Multiple decades of stocking has resulted in limited hatchery introgression in wild brook trout (Salvelinus fontinalis) populations of Nova Scotia

Sarah Lehnert, Shauna Baillie, John MacMillan, Ian Paterson, Colin Buhariwalla, Ian Bradbury & Paul Bentzen
Many populations of freshwater fishes are threatened with losses, and increasingly, the release of hatchery individuals is one strategy being implemented to support wild populations. However, stocking of hatchery individuals may pose long-term threats to wild populations, particularly if genetic interactions occur between wild and hatchery individuals. One highly prized sport fish that has been heavily stocked throughout its range is the brook trout (Salvelinus fontinalis). In Nova Scotia, Canada, hatchery brook trout have been...

Supplementary material for: Long branch attraction biases in phylogenetics

Edward Susko & Andrew Roger
Long branch attraction is a prevalent form of bias in phylogenetic estimation but the reasons for it are only partially understood. We argue here that it is largely due to differences in the sizes of the model spaces corresponding to different trees. Trees with long branches together allow much more flexible internal branch-length parameter estimation. Consequently, although each tree has the same number of parameters, trees with long branches together have larger effective model spaces....

Data from: Divergent and linked selection shape patterns of genomic differentiation between European and North American Atlantic salmon (Salmo salar)

Sarah Lehnert, Tony Kess, Paul Bentzen, Marie Clément & Ian Bradbury
As populations diverge many processes can shape genomic patterns of differentiation. Regions of high differentiation can arise due to divergent selection acting on selected loci, genetic hitchhiking of nearby loci, or through repeated selection against deleterious alleles (linked background selection); this divergence may then be further elevated in regions of reduced recombination. Atlantic salmon (Salmo salar) from Europe and North America diverged >600,000 years ago and despite some evidence of secondary contact, the majority of...
