| Notes | Shifts in fish genetics can show how fish interact with their environment. Here, the author looks at coastal steelhead and finds some differences, both in terms of basin size and geographical area. The author notes that, “Steelhead allelic frequencies for several isozymes gradually change in a north to south pattern in populations along the Oregon coast. . . . Small basin populations were shown to have some distinct differences from the large basin populations. While the cause of the differences is not known, the effects of genetic drift on these small, relatively isolated populations is suggested.” (p.42) Major professor was Hiram W. Li. |
