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...

Survival of natural and planted seedlings under a shelterwood in southwest Oregon

Creator:: Helgerson, O. T., Wearstler, Kenneth A., Bruckner, Werner K., and Oregon State University. Forest Research Laboratory
Abstract:: The effects of naturally shaded microsites on survival and height growth of natural and planted seedlings were evaluated after an initial shelterwood harvest in the eastern Siskiyou Mountains of southwestern Oregon. After 2 years, the probabilities of survival for planted Douglas-fir (84 percent) and ponderosa pine (56 percent) were significantly...

The role of costimulation and adjuvants in the development of T cell effector and memory responses

Creator:: Maxwell, Joseph R.
Abstract:: T cells are one of the key cells in the immune system. Although they are not the first line of defense against a pathogen, their functions can greatly enhance the phagocytosis and destruction of pathogens as well as the development of antibody responses. Furthermore, even when responding T cells have...

The effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin on T cell activation

Creator:: Shepherd, David M.
Abstract:: The immune system has been identified as a very sensitive target for the toxic effects of 2,3,7,S-tetrachlorodibenzo-p-dioxin (TCDD). Exposure to TCDD has been shown to disrupt the generation of both cell-mediated and humoral T cell-dependent immunity in laboratory animals; however, the mechanism remains unknown. In this dissertation, the hypothesis is...

Testing for location after transformation to normality

Creator:: Halawa, Adel Mahmoud
Abstract:: In the problem of testing the median using a random sample from a certain distribution, and if no other parametric family is suggested, the t-test is known to be the optimal procedure when this distribution is normal. If the sample appears to be non-normal, one has the choice either to...

The influence of aryl hydrocarbon receptor activation on T cell fate

Creator:: Funatake, Castle J.
Abstract:: 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) and related compounds are well-recognized for their immunosuppressive activity, which is mediated through an intracellular receptor and transcription factor, aryl hydrocarbon receptor (AhR). Laboratory animals exposed to TCDD are less resistant to infection and have severely impaired humoral and cell-mediated immune responses. This dissertation addressed the hypothesis that...
