Analyzing patterns of woody plant richness at multiple spatial scales with modeled photosynthesis

Creator:: Swenson, Jennifer J.
Abstract:: The hump-shaped relationship that predicts highest species richness (species/unit area) at intermediate levels of productivity was examined for woody plants across the Pacific and Inland Northwest of the U.S. Many studies have examined this relationship at regional scales, but commonly use species range maps and surrogate measures of productivity (e.g....

Middle school mathematics teachers' subject matter knowledge and pedagogical content knowledge of probability : its relationship to probability instruction

Creator:: Swenson, Karen A.
Abstract:: As a result of the calls for reform in mathematics education and the ever-changing nature of mathematics, today's teachers face the challenge of teaching unfamiliar content in ways that are equally unfamiliar. In view of this challenge, the purpose of this study was to investigate middle school teachers' subject matter...

Analyzing powers and cross sections of inclusive polarized proton scattering on ²⁰⁸Pb

Creator:: Chen, Xiao-yan
Abstract:: Inclusive polarized proton-nucleus scattering at 290 and 500 MeV was performed using a ²⁰⁸Pb(51 mg/cm²) target. A broad range (0-250 MeV) of excitation energy has been studied over the 4° - 27° angular range. The measured analyzing power and cross section of the continuum are compared with the recent DWIA...

Effects of intrinsic factors in the transmission of bean yellow mosaic virus by aphids

Creator:: Sohi, Sardara Singh
Abstract:: The effects of the inherent transmissibility of the virus and of the inherent transmitting ability of aphids on the transmission of bean yellow mosaic virus (BYMV) were studied along with four virus-vector relationships of BYMV and the green peach aphid, Myzus persicae (Sulz.). In addition, investigations were made on the...

Environmental biology of Eriosoma pyricola Baker and Davidson

Creator:: Sethi, Satnam Lal
Abstract:: A method of culturing Eriosoma pyricola on detached root pieces was developed to ensure a regular supply of aphids for experimental work. Another method was designed for studying the alate sexuparae formation in woolly pear aphid, whereby growing plants were infested so that the aphids or their progeny could be...

Some factors affecting aphid transmission of cucumber mosaic virus

Creator:: Stimmann, Michael W.
Abstract:: The frequency of aphid transmission of cucumber mosaic virus from diseased plants at different times after inoculation was determined. A cycle of infectious virus was found. Primary leaves of lima bean plants were inoculated mechanically when the first trifoliate leaf appeared and were kept at different temperatures. At 24° C...

Transmission variation and loss of aphid transmissibility of bean yellow mosaic virus

Creator:: Kamm, James A.
Abstract:: Several bean yellow mosaic virus (BYMV) strains, presumably not transmissible by aphids, were studied to determine the biological and environmental conditions which would possibly result in aphid transmission of these strains. Investigations were made to study the effect of different aphid rearing conditions on the transmission frequency of BYMV. Also,...
