Data from: Historical and anthropogenic factors affecting the population genetic structure of Ontario’s inland lake populations of walleye (Sander vitreus)

Ryan P. Walter, Christopher J. Cena, George C. Morgan & Daniel D. Heath
Populations existing in formerly glaciated areas often display composite historical and contemporary patterns of genetic structure. For Canadian freshwater fishes, population genetic structure is largely reflective of dispersal from glacial refugia and isolation within drainage basins across a range of scales. Enhancement of sport fisheries via hatchery stocking programs and other means has the potential to alter signatures of natural evolutionary processes. Using 11 microsatellite loci genotyped from 2182 individuals, we analyzed the genetic structure...

Data from: Disentangling invasion processes in a dynamic shipping - boating network

Anaïs Lacoursière-Roussel, Christopher W. McKindsey, Dan G. Bock, Melania E. Cristescu, Frédéric Guichard, Philippe Girard & Pierre Legendre
The relative importance of multiple vectors to the initial establishment, spread, and population dynamics of invasive species remains poorly understood. This study used molecular methods to clarify the roles of commercial shipping and recreational boating in the invasion by the cosmopolitan tunicate, Botryllus schlosseri. We evaluated i) single vs. multiple introduction scenarios, ii) the relative importance of shipping and boating to primary introductions, iii) the interaction between these vectors for spread (i.e., the presence of...

Data from: Sex-biased genetic component distribution among populations: additive genetic and maternal contributions to phenotypic differences among populations of Chinook salmon

Tutku Aykanat, Colleen A. Bryden & Daniel D. Heath
An approach frequently used to demonstrate a genetic basis to population-level phenotypic differences is to employ common garden rearing designs, where observed differences are assumed to be attributable to primarily additive genetic effects. Here, in two common garden experiments, we employed factorial breeding designs between wild and domestic, and among wild populations of Chinook salmon (Oncorhynchus tshawytscha). We measured the contribution of additive (VA) and maternal (VM) effects to the observed population differences for 17...
