Some effects of dissolved oxygen concentration on feeding, growth and bioenergetics of juvenile Coho salmon

Creator:

Thatcher, T. O.

Abstract:

The effects of three levels of dissolved oxygen (8, 5 and 3 mg/l) upon the feeding, growth and bioenergetics of juvenile coho salmon, Oncorhynchus kisutch (Walbaum), were determined in laboratory studies. Experiments with individual fish were conducted during the summer, fall and spring to measure rates of food consumption, standard...

Nitrogen fixation by scotch broom (Cytisus scoparius L.) and red alder (Alnus rubra Bong.) planted under precommercially thinned Douglas fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:

Helgerson, O. T.

Abstract:

Red alder (Alnus rubra Bong.), scotch broom (Cytisus scoparius L.) and snowbrush (Ceanothus velutinus Dougi ) were planted under precommercially thinned Douglas-fir (Pseudotsuga iuenziesil Mirb Franco) in the central Oregon Cascades. Plug grown red alder had significantly greater survival than all wildling propagules except for the second broom planting Browsing...
