| life history and habitat analysis of the eye fluke diplostomum spathaceum (trematoda: diplostomatidae) in utah. | diplostomum spathaceum which is widespread throughout utah in desert, mountain valley, and high alpine lakes, causes a disease known as diplostomatosis or eye fluke disease. snails (756) were examined and two species, lymnaea stagnalis and l. palustris were positive for d. spathaceum. examination of 838 fish, which included 19 species, revealed 10 species (salmo trutta, catostomus discobulus, salmo clarki, micropterus salmoides, catostomus platyrhynchus, salmo gairdneri, gila atraria, catostomus ... | 1977 | 864559 |
| pesticide and pcb residues in the upper snake river ecosystem, southeastern idaho, following the collapse of the teton dam 1976. | the teton dam in southeastern idaho collapsed on june 5, 1976. the resulting flood damaged a large area and caused the release of toxicants into the snake river. a pesticide recovery team in a helicopter worked the flooded area for three weeks and collected 1,104 containers, about 35% of which contained toxicants. it was estimated that less than 60% of the lost pesticide containers were recovered. this paper addresses the results of a one-time sampling effort designed to determine the magnitude ... | 1979 | 120135 |
| morphological and genetic structuring in the utah lake sucker complex. | population decline in the federally endangered june sucker (chasmistes liorus), a lakesucker unique to utah lake, utah, has been attributed in part to hybridization with the more widespread utah sucker (catostomus ardens). as a group, suckers in utah lake exhibit considerable external morphological variation. meristic and morphological ambiguities, presumably the result of hybridization, create a continuum of intermediate forms between chasmistes and catostomus extremes and prevent definitive id ... | 2008 | 19067800 |
| rangewide molecular structuring in the utah sucker (catostomus ardens). | the utah sucker (catostomus ardens) is endemic to the bonneville basin and the upper snake river drainage in western north america, and is thought to hybridize with the federally endangered june sucker (chasmistes liorus mictus) in utah lake (bonneville basin). here we describe the discovery of a major subdivision in utah suckers (4.5% mitochondrial sequence divergence) between the ancient snake river drainage and the bonneville basin. this boundary has not previously been recognized in utah suc ... | 2006 | 16780436 |
