Effects of temperature and other abiotic and biotic factors on development and survival of the immature stages of the alfalfa leafcutting bee, Megachile pacifica (Panzer) (=rotundata (F.)) (Hymenoptera:Megachilidae)

Creator:: Undurraga O., Jaime M.
Abstract:: Larval mortality of leafcutting bee, Megachile pacifica (Panzer) (= rotundata (F.)), is high, usually exceeding 50%. Parasites and predators are not a limiting factor in the survival of the progeny. The disease chalk brood has been an important mortality factor since 1974. Inadequate food supply, pollen and nectar, may affect...

Fitzgerald’s idealism and the question of wealth

Creator:: Wood, Amy
Abstract:: In This Side of Paradise, The Great Gatsby, and several of his short stories, F. Scott Fitzgerald questions the importance of wealth as a factor in supporting happiness and fostering the American Dream on an individual basis. With these texts, Fitzgerald acknowledges that wealth is a factor and, simultaneously, a...

Electrical characterization of transparent p–i–n heterojunction diodes

Creator:: Hoffman, R. L., Wager, J. F., Jayaraj, M. K., and Tate, Janet
Abstract:: Transparent p – i – n heterojunction diodes are fabricated using heavily doped, p-type CuYO₂ and semi-insulating i-ZnO thin films deposited onto a glass substrate coated with n-type indium tin oxide. Rectification is observed, with a ratio of forward-to-reverse current as high as 60 in the range −4–4 V. The...

Characterization of Pacific whiting proteinase P-II and partial cloning of cathepsins L and K cDNA from rainbow trout liver

Creator:: Nickel, Xianbin F.
Abstract:: Proteinase P-II purified from parasitized Pacific whiting muscle was previously identified to be one form of cathepsin L. It appeared to be present in three isozymatic forms on non-denaturing PAGE gel stained for activity. Its autolytic degradation was observed on SDS-PAGE gel under its optimum condition, 55°C and pH 5.5,...

A survey of alfalfa pollinators and polination in the San Joaquin Valley of California with emphasis on establishment of the alkali bee

Creator:: Torchio, Philip F.
Abstract:: The study involves the establishment, management, and behavioral observations of Nomia melanderi Cockerell and Megachile rotundata (Fabricius) in California, a survey of native bees within western Fresno County, a determination of selfing and/or parthenocarpy in two fields of alfalfa, and observations on the honeybee as an alfalfa pollinator. The alkali...

Persistence of prodiamine and norflurazon herbicides in soil and their activity on alfalfa rotational crops

Creator:: Fischer, Vernon F.
Abstract:: Norflurazon [4-chloro-5-(methylamino)-2(3-(trifluoromethyl) phenyl)- 3(2H)- pyridazinone] and prodiamine (N3, N3-di-n-propy1-2,4- dinitro-6-(trifluoromethyl)-m-phenylenediamine) are two herbicides being considered for weed control in alfalfa. Rotational crops following alfalfa may be sensitive to residues of these herbicides. Studies were conducted in Oregon and Washington to examine the soil persistence and activity of these herbicides on...

Effects of Elevated CO₂ on Speckled Sanddab (Citharichthys stigmaeus) Behavior

Creator:: Andrade, Jessica F.
Abstract:: The direct and indirect effects of ocean acidification (OA) are a growing concern, particularly in areas already experiencing elevated levels of oceanic CO₂. Studies with marine fishes suggest that elevated CO₂ levels may affect behavior by interfering with an important brain neurotransmitter. Studies examining the effects of OA fish behavior...

Influences of island characteristics on community structure and species incidence of desert bats in a near-shore archipelago, Baja California, Mexico

Creator:: Frick, Winifred F.
Abstract:: Island biogeography has strongly influenced the study of biodiversity because archipelagos provide natural model systems for investigating patterns of diversity and the processes that shape ecological communities. I investigated the influence of area and isolation of islands (n = 32) in the Gulf of California, Mexico on patterns of richness,...

Pulse reader for ionization chambers

Creator:: Boothe, Gary F.
Abstract:: A pulse reader for ionization chambers has been developed, tested, and calibrated. An insulated gate field effect transistor (IGFET) was used to detect the pulses and Victoreen Model 362 Pocket Chambers were used as ionization chambers. The energy dependence of the Victoreen Model 362 Pocket Chamber was determined to be...
