| Abstract: | The Kenai River supports two temporal runs of Chinook salmon. Previous studies detected genetic differences between these early and late Chinook salmon runs using microsatellite markers. Here we examine a baseline of 11 populations using 42 single nucleotide polymorphism markers to determine population structure, which provides insight into potential identifiable units (reporting groups) for mixed stock analysis. As with earlier studies, we confirmed significant genetic difference between the temporal runs. This new baseline also includes larger sample sizes for several populations (lower Kenai River mainstem, Quartz Creek, and Grant Creek), enabling a more fine-scale analysis of reporting groups. The baseline was examined for variation at three levels of population groupings: 1) broad-scale (2 groups); 2) mid-scale (3 groups); and 3) fine-scale (6 groups). Baseline tests indicated that there is sufficient variation within population groups for all three levels for Kenai River Chinook salmon genetics applications. |
