Influence of dissolved oxygen concentration and swimming velocity on food consumption and growth of juvenile Coho salmon

Creator:: Hutchins, Floyd E.
Abstract:: Laboratory studies were conducted on the food consumption, growth, and bioenergetics of juvenile coho salmon (Oncoynchus kisutch) held at various swimming velocities and dissolved oxygen concentrations at 15 C. Food consumption and growth of salmon fed to repletion on housefly larvae (Mus domesticus) were reduced by increasing activity at and...

Nutritional aspects of artificially feeding captive and wild deer

Creator:: Dean, Ronald E.
Abstract:: Most of the nutritionally related difficulties of winter feeding deer apparently result from either poor acceptability of artificial rations or digestive disturbances that result from feeding starved animals feeds to which they are not accustomed. Reported in this thesis are studies conducted with both captive and wild deer concerning acceptability...

Man and the land : an ecological history of fire and grazing on eastern Oregon rangelands

Creator:: Shinn, Dean Allison
Abstract:: Ecological and historical information are combined in examining the environmental influence of fire and grazing on rangelands in eastern Oregon through time. Competitive relationships between herbaceous and woody flora in the northern Great Basin are discussed, focusing broadly on the shrubsteppe regions 'of Franklin and Dyrness (1973) but with special...

Pool absorption of gas entrained by a plunging liquid jet

Creator:: Hauxwell, Gerald Dean
Abstract:: A mathematical model was developed to predict the absorption rate of a slightly soluble gas entrained by a plunging liquid jet. The single parameter of the model, the transfer factor, TF, was defined as the summation of the product of the mass transfer coefficient and interfacial area over all the...

The effect of soil acidity and lime placement on root growth and yield of winter wheat and alfalfa

Creator:: Kauffman, Marvin Dean
Abstract:: The application of lime to an acid Nekia soil significantly increased the yield of winter wheat and alfalfa in a field experiment. Crop yields maximized when the lime was partially mixed into the surface four inches of the soil. Thorough mixing of the lime into the surface six inches of...
