The Ecophysiology of Thiamine Deficiency Complex : Evaluating Sources of Thiaminase in Great Lakes Food Webs

Creator:: Evans, Allison N.
Abstract:: Thiamine (vitamin B₁) is required by all living organisms for carbohydrate metabolism and synthesis of amino acids. Thiamine deficiency is responsible for several related classes of early life stage mortality disorders in salmonines, including Thiamine Deficiency Complex (TDC) in the Laurentian Great Lakes, Cayuga Syndrome in the Finger Lakes, and...

Territorial behavior in juvenile steelhead trout (Oncorhynchus mykiss) : how redside shiner (Richardsonius balteatus) influence intraspecific interactions

Creator:: Tinus, Craig A.
Abstract:: Juvenile steelhead are known to associate with shiner groups, though they also compete for food. Steelhead form dominance hierarchies within cohorts and aggressively defend feeding territories against all other fish. This study focused on the differential effect of shiner competition on steelhead of different social standing. Survival of subordinate juvenile...

Born to run? Integrating individual behavior, physiology, and life histories in partially migratory steelhead and rainbow trout (Oncorhynchus mykiss)

Creator:: Sloat, Matthew R.
Abstract:: Steelhead and rainbow trout are common names for marine-migratory (anadromous) and freshwater-resident forms of Oncorhynchus mykiss, a partially migratory salmonid fish. Anadromous and resident forms are sympatric and can produce offspring with a life history different from their own (i.e., steelhead parents can produce rainbow trout offspring and vice versa)....

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...

Early self-sorting behavior in Chinook salmon is correlated with variation in growth, behavior and morphology later in life.

Creator:: Unrein, Julia R.
Abstract:: Juvenile Chinook salmon (Oncorhynchus tshawytscha) exhibit an array of life history tactics in Oregon's Willamette River Basin, yet we do not know to what extent it is driven by phenotypic plasticity or whether it is predetermined and how conditions in the early rearing environment may affect phenotype expression. We have...

Year-class regulation of mid-upper Columbia River spring Chinook salmon Oncorhynchus tshawytscha : the role of juvenile size, growth, and migratory behavior

Creator:: Tomaro, Londi M.
Abstract:: Early ocean residence is assumed to be a critical period for juvenile Pacific salmon Oncorhynchus spp. However, the specific mechanisms influencing growth and survival in the ocean have not been identified for most populations. Therefore, three hypotheses regarding the relationship between early marine residence and subsequent survival of mid-upper Columbia...

Influences of Thermal and Trophic Heterogeneity on Phenology, Growth, and Resource Use by Juvenile Coho Salmon

Creator:: Campbell, Emily Y.
Abstract:: Ecological resources available to freshwater fish shift spatially, temporally and across life stages. To better understand how spatial-temporal availability of resources influence fish, I examined the phenologies of hatching and emergence of Coho Salmon (Oncorhynchus kisutch) in streams with contrasting and strongly defined seasonal thermal variability. The study streams included...

The importance of egg size for the diversity of salmonids

Creator:: Leblanc, Camille A.
Abstract:: Understanding the origin and nature of intra specific biodiversity enables us to better conserve and manage animal populations. Biological diversity is seen at different scales and for different traits such as behavior, morphology, physiology, and life history. Behavior is especially important since behavioral changes are believed to precede changes in...

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...
