Drought is a major limiting abiotic stress influencing wheat production in
many parts of the world. The erratic nature of water deficits makes breeding
and selection for drought resistance deficient. In environments with late
season drought stress, yield losses are usually associated with kernel abortion
or reduction in kernel growth....
Genetic resistance is the most appropriate way to control diseases in crop plants. Resistance can be described as qualitative (involving a gene-for-gene system) or quantitative (with continuous distribution of disease levels). The relationships between different types of resistance remain obscure, as does the genetics of quantitative traits. The use of...
Samples of weathervane scallops taken on Oregon Department of
Fish and Wildlife cruises off Oregon waters during 1981-1982 were
analyzed for a comparative growth study. No evidence of internal
growth marks were found in the shell structure when analyzed by the
acetate peel technique. Internal growth lines formed in the...
Until the 1930s, flows of the Colorado River maintained approximately 781,060 hectares of wetlands in its delta. These wetlands provided important feeding and nesting grounds for resident and migratory birds as well as spawning and protection habitat for many fish and other invertebrate species. However, the Delta's wetlands started to...
Setting aside the traditional simplistic “tragedy of the commons” notion, fisheries crises observed in the Northern Atlantic may be seen as the result of “mismatches” in the decision making process. The collapse of two fisheries, Atlantic Cod (Gadus morhua) in Canada and European Hake (Merluccius merluccius) in Europe, illustrate the...
The Department of Nuclear Engineering and Radiation Health Physics (NE/RHP) at Oregon State University (OSU) has been developing an innovative modular reactor plant concept since being initiated with a Department of Energy (DoE) grant in 1999.
This concept, the Multi-Application Small Light Water Reactor (MASLWR), is an integral pressurized water...
Indigenous and Latinx communities have always used storytelling to pass along ancestral histories and memories, whether it be through the act of speaking, performing or other types of artwork. This thesis examines the ways that queer Latinx artists are retelling the stories that have been mistold to erase, repress and...
During the Colonial Period, in Mexico there was no rational
forest development policy and, as a result, forest resources were
squandered and to a considerable extent destroyed. During the
Nineteenth Century, a rational forest policy began to be promoted, but
in the end, it was translated into a policy of...
