	title = {The Oregon Coastal Subprovince, a New Biogeographic Subprovince for Primary Freshwater Fishes in Oregon},
	year = {2008},
	note = {"The goals of this study were: 1) to describe fishes in the genera Catostomus and Ptychocheilus in the Oregon Coastal Subprovince using morphological data and mitochondrial cytochrome b sequences; 2) to investigate the relationships of fishes in the Oregon Coastal Subprovince to nearby provinces; and 3) to address competing distribution theories." (from the Abstract)  The author proposes that, based on the endemic distribution of freshwater fishes, the Oregon coast may deserve designation as a biogeographic subprovince, ranging from the Miami River in the north to the Sixes River in the south. Possible explanations for the distribution of these fishes are considered. The major professor was Douglas Markle.},
