The influence of sex, migration distance, and latitude on expression of anadromy in Oncorhynchus mykiss

Creator:: Ohms, Haley
Abstract:: The evolution and maintenance of multiple phenotypes within populations is an interesting evolutionary and ecological question, and is becoming increasingly important for the restoration and conservation of partially migratory species. In particular, why individuals adopt a particular phenotype has been the focus of numerous research efforts. In the partially migratory...

Description and prediction of broad-scale spatial variability in expression of anadromy in female Oncorhynchus mykiss in the John Day River, Oregon, USA

Creator:: Mills, Justin S.
Abstract:: Partial migration is a common migratory behavior where some individuals in a population migrate and others do not. Patterns of partial migration can vary dramatically, especially for species that inhabit a wide range of environments. I described and predicted spatial variation in marine migration (anadromy) of female Oncorhynchus mykiss (steelhead...

How the animals found their places : pattern detection, experimentation, and epistemology in a high desert stream fish assemblage

Creator:: White, Seth Michael
Abstract:: I examined the relative roles of biotic and abiotic factors in structuring redband trout Oncorhynchus mykiss distributions in the South Fork John Day. I first examined the relationship between the biological traits of the fish assemblage and riparian-geomorphic features in context of prevailing theories of stream ecology stemming from the...

From continua to patches : longitudinal patterns in the Middle Fork of the John Day River, Oregon

Creator:: Wright, Kristopher Keith
Abstract:: The Middle Fork John Day River is composed of low gradient, alluvial valley segments separated by constrained, canyon-like reaches, and has a history of multiple land-uses. These factors can alter the physical and biological structure of streams, and disrupt the longitudinal river continuum. I examined habitat, fish, macroinvertebrates, and primary...

Early maturing males in a partially migratory population of anadromous and resident rainbow trout Oncorhynchus mykiss: influences of individual condition and stream temperature

Creator:: McMillan, John R.
Abstract:: Alternative male phenotypes in salmonine fishes arise from individuals that mature as either larger and older anadromous marine-migrants or as smaller and younger freshwater residents. Variability in age and size of males at maturity is hypothesized to be preceded by early differences in growth in size and lipid storage. Water...

Seasonal life history of Oncorhynchus mykiss in the South Fork John Day River Basin, Oregon

Creator:: Tattam, Ian A.
Abstract:: Understanding seasonal changes in growth, survival, and movement rates is crucial to salmonid management. These life history characteristics provide a context for evaluation of management actions. We evaluated the life history of individually marked Oncorhynchus mykiss gairdneri in the South Fork John Day River basin in Northeastern Oregon. This thesis...

Enzyme-Linked Immunosorbent Assay (ELISA) of Vitellogenin in Temperate Basses (Genus Morone): Plasma and In Vitro Analyses

Creator:: Heppell, Scott A., Jackson, Leslie F., Weber, Gregory, M., and Sullivan, Craig, V.
Abstract:: Blood levels of the egg yolk precursor vi- tellogenin (VTG) can be used as a deﬁnitive marker for the onset and progress of maturation in female teleosts. In the present study, an enzyme-linked immunosorbent assay (ELISA) was developed to measure VTG in blood plasma from three species of temperate basses....

Biophysical factors driving the distribution and abundance of redband/steelhead trout (Oncorhynchus mykiss gairdneri) in the South Fork John Day River Basin, Oregon, USA

Creator:: Madriñán, Luis Francisco
Abstract:: The overall goal of this study was to identify multiple scales of habitat use and habitat electivity by redband/steelhead trout and define the limiting factors affecting the distribution patterns of this species during summer flows. The main objective in chapter 2 was to identify the most important habitat associations that...
