Size-structured spatial patterns as a measure of larval dispersal and emigration

Creator:: Markle, Douglas F.
Abstract:: Size-structured spatial patterns in larvae of 2 sucker and 3 minnow species are described from fixed-site sampling in Upper Klamath Lake, Oregon, and are used to demonstrate patterns of size-based losses downstream and retention in the lake. The smallest larvae of shortnose suckers (Chasmistes brevirostris), Lost River suckers (Deltistes luxatus),...

The Oregon Coastal Subprovince, a new biogeographic subprovince for primary freshwater fishes in Oregon

Creator:: Kettratad, Jes
Abstract:: The Pacific Northwest has a relatively low diversity of primary freshwater fishes with most of the endemism and diversity in the Columbia River and Klamath River. However, the Oregon Coastal Subprovince defined as the coastal rivers from Miami River in the north to Sixes River in the south, has a...

Taxonomy and systematic relationships of tui chubs (Siphateles: Cyprinidae) from Oregon's Great Basin

Creator:: Remple, Stacy L.
Abstract:: There are three recognized species of Siphateles from the Great Basin; S. alvordensis, S. boraxobius and the tui chub, S. bicolor. One species, S. boraxobius, is endangered and one population of tui chub at Hutton Spring is threatened. Despite several morphological and molecular studies, the taxonomy and relationships of tui...

Spawning, larval recruitment, and early life survival of Pacific lampreys in the South Fork Coquille River, Oregon

Creator:: Brumo, Abel F.
Abstract:: Recently, there has been concern over the decline of the Pacific lamprey, Lampetra tridentata, in the northwestern United States. However, effective management has been impeded by data gaps in basic biology, especially in the early life stages. Consequently, in 2004 and 2005 I examined reproductive ecology, larval recruitment, and lamprey...

Metamorphosis, growth, and settlement of Pacific sanddab (Citharichthys sordidus) to a continental shelf nursery, inferred from otolith microstructure

Creator:: Donohoe, Christopher James
Abstract:: Processes of metamorphosis, settlement, and growth were examined in Pacific sanddab using field studies and otolith microstructure. This flatfish transforms at large sizes, has a gradual metamorphosis, and settles to a nursery on the middle continental shelf. Eye migration takes 3 months and "metamorphosis proper" which begins after completion of...

Species identification of Klamath Basin suckers (Pisces : Catostomidae) and an assessment of hybridization using anonymous nuclear loci

Creator:: Wagman, David Wolfe
Abstract:: Low copy number anonymous nuclear loci were used to search for species markers in four species of Klamath Basin suckers. We sequenced 28 randomly chosen loci representing 10,421 bp; 21 loci were similar to sequences in GenBank. Eight fixed sequence differences were found among Klamath species. Locus 120 contained rare...

Settlement, distribution, growth, and mortality of juvenile dover sole (Microstomus pacificus) off northern Oregon

Creator:: Toole, C. L. (Christopher L.)
Abstract:: Demographic characteristics of juvenile Dover sole (Microstomus pacificus) were examined in relation to physical and biotic factors to develop a hypothesis explaining annual variations in recruitment. Surveys were conducted along the Oregon continental shelf at depths between 50-400 m bimonthly during 1989 and annually (in March) between 1990 and 1993....

Age and growth of young-of-the-year Lost River suckers Deltistes luxatus and shortnose suckers Chasmistes brevirostris of Upper Klamath Lake, Oregon

Creator:: Logan, Daniel Joseph
Abstract:: Upper Klamath Lake in southern Oregon has two species of lacustrine suckers, Lost River sucker Deltistes luxatus and shortnose sucker Chasmistes brevirostris that were historically abundant. Results of surveys performed in the mid-1980's indicated that populations of both species were declining and ageing with apparent recruitment failure in most years...

Taxonomic analyses of the Oregon chub, Oregonichthys crameri

Creator:: Bills, Debra T.
Abstract:: The Oregon chub. Oregonichthys crameri. one of Oregon's endemic freshwater fishes. is restricted to the Willamette and Umpqua rivers and their tributaries. Specimens from the two rivers have traditionally been considered the same species. The goal of this study was to re-examine that assumption and determine if the Willamette Oregon...
