Incinerated sewage sludge use as a soil amendment for sweet corn (Zea mays L.)

Creator:: Mellbye, Mark Edward
Abstract:: Field and greenhouse experiments were conducted to determine the suitability of using incinerated sewage sludge ash as a soil amendment for sweet corn production on Willamette silt loam. In 1977, field plots were treated with 0, 11, 22, and 43 mt/ha of ash containing lime, in factorial combination with a...

You are What, When, Where, and How you Eat : Mercury in Avian Food Webs across Multiple Spatial Scales

Creator:: Jackson, Allyson K.
Abstract:: Human alterations of landscapes take many forms, one of which is anthropogenic pollution. Mercury (Hg) is a complex contaminant because its uptake into the food web is not driven entirely by loading to the system; methylation is necessary to make Hg bioavailable and toxic to fish and wildlife. Because methylation...

The effects of atrazine on growth of flax (Linum usitatissimum L.) plants and on yield, chemical composition and germination of flax seeds

Creator:: Locatelli, Eduardo Atilio
Abstract:: Reports of previous research indicated a stimulatory effect of triazine herbicides on growth, yield and protein content of plants and seeds of various species. Studies were conducted in the greenhouse, laboratory and field to investigate the effects of atrazine (2-chloro-4-ethylamino-6-a sopropylarnino- s-triazine) on growth, yield, seed composition, and seed germination...

Genetic variation and phenotypic stability among three elevational sources of coastal Douglas-fir from southwest Oregon

Creator:: Mangold, Robert
Abstract:: This study had three objectives: (1) to determine the degree to which within-source genetic variation and genetic correlations differ among elevational sources of Douglas-fir [Pseudotsuga menziesii (Mirb). Franco var. menziesii]; (2) to ascertain the degree to which phenotypic stability differs among and within elevational sources; and (3) to compare the...

Larval settlement and juvenile group dynamics in the domino damselfish (Dascyllus albisella)

Creator:: Booth, David J. (David John), 1958-
Abstract:: Patterns of settlement of larvae and population dynamics of juveniles are poorly known for coral reef fishes. During 1987 to 1989, I studied these phenomena in the domino damselfish (Dascyllus albisella), a species endemic to the Hawaiian Islands. Larvae settle onto branching coral heads as new recruits (10-15 mm in...

Environmental behavior of Dacthal

Creator:: Wettasinghe, Asoka
Abstract:: The herbicide, Dacthal (dimethyl 2,3,5,6,-tetrachloroterephthalate) is hydrolyzed to give the corresponding diacid and this derivative is a common contaminant in ground water. In the Ontario region of eastern Oregon the use of this herbicide on onions has resulted in the contamination of an aquifer with this derivative. Since movement to...

The nature and properties of amorphous colloids formed from Mazama tephra

Creator:: Dingus, Delmar DeLee
Abstract:: Soil samples from the Mazama tephra deposit were collected from the AC and C2 horizons at five different locations along the axis of the main depositional lobe. The clay fraction from the samples was recovered and studied by means of chemical, x-ray, DTA and electron microscopy methods in order to...

Nutritional and management strategies of trace mineral supplementation for beef cattle

Creator:: Puerto Hernandez, Gracia Maria
Abstract:: Two studies evaluated the mineral status of supplemented beef cattle over two different methods of supplementation. The objective of study 1 was to evaluate the mineral status at weaning and subsequent post-weaning performance of calves supplemented prior to weaning, with limited-fed supplements fortified with trace minerals (Cu, Se, and Zn)...

Downstream Rearing Chinook Salmon (Oncorhynchus tshawytscha) in the Upper Mainstem of the John Day River

Creator:: Scheu, Michael P.
Abstract:: Juvenile Chinook Salmon (Oncorhynchus tshawytscha) leave the natal reach at different times and move downstream at different rates which can increase their productivity by allowing them to utilize habitats on different temporal scales and spreading risk of localized stochastic events. This life history diversity can also allow fish to adapt...
