The Interplay Of Light And The Circadian Clock. Independent Dual Regulation Of Clock-Controlled Gene Ccg-2(Eas), Guiseppina Arpaia, Jennifer J. Loros, Jay C. Dunlap, Giorgio Morelli, Guiseppe Macino Aug 1993

The Interplay Of Light And The Circadian Clock. Independent Dual Regulation Of Clock-Controlled Gene Ccg-2(Eas), Guiseppina Arpaia, Jennifer J. Loros, Jay C. Dunlap, Giorgio Morelli, Guiseppe Macino

Dartmouth Scholarship

Ambient light is the major agent mediating entrainment of circadian rhythms and is also a major factor influencing development and morphogenesis. We show that in Neurospora crassa the expression of clock-controlled gene 2 (ccg-2), a gene under the control of the circadian clock and allelic to the developmental gene easy wettable (eas), is regulated by light in wild-type strains. Light elicits a direct and important physiological effect on ccg-2(eas) expression as demonstrated using several mutant Neurospora strains. In white collar mutants (wc-1 and wc-2) that are “blind” to blue light, ccg-2(eas) mRNA shows no variation following illumination with saturating light. …

Maillard Reaction Products And Their Relation To Complications In Insulin-Dependent Diabetes Mellitus, David R. Mccance, Daniel G. Dryer, John A. Dunn, Karen E. Bailie, Suzanne R. Thorpe, John W. Baynes, Timothy J. Lyons

Faculty Publications

Glycation, oxidation, and browning of proteins have all been implicated in the development of diabetic complications. We measured the initial Amadori adduct, fructoselysine (FL); two Maillard products, N epsilon-(carboxymethyl) lysine (CML) and pentosidine; and fluorescence (excitation = 328 nm, emission = 378 nm) in skin collagen from 39 type 1 diabetic patients (aged 41.5 +/- 15.3 [17-73] yr; duration of diabetes 17.9 +/- 11.5 [0-46] yr, [mean +/- SD, range]). The measurements were related to the presence of background (n = 9) or proliferative (n = 16) retinopathy; early nephropathy (24-h albumin excretion rate [AER24] > or = 20 micrograms/min; n …

Diet And Colon Cancer Risk In The Population Of Thailand, Nithat Sirichotiratana May 1993

Diet And Colon Cancer Risk In The Population Of Thailand, Nithat Sirichotiratana

Loma Linda University Electronic Theses, Dissertations & Projects

Epidemiological studies have emphasized environmental influences, especially a diet high in animal fat and low in fiber, as major risk factors for colon cancer. In order to examine the relationship between dietary fat and fiber and occurrence of colon cancer, patient medical records from the National Cancer Institute between 1981-1991 were used for the first hospital-based case-control study of diet and colon cancer in Thailand. These records included a total of 168 cases and 357 controls. Data on the frequency consumption of various food items were obtained by using an existing food frequency questionnaire, completed as part of patient’s history …

Preliminary Public Health Assessment: Petrochem Recycling Corporation/Ekotek Salt Lake City, Salt Lake County, Utah, Agency For Toxic Substances And Disease Registry, Divisoin Of Health Assessment And Consultation

All U.S. Government Documents (Utah Regional Depository)

The Petrochem/EkoTek site was operated by several owners as a refinery from 1953 until 1978 and as a hazardous waste storage treatment facility and a petroleum recycling facility from 1978 through 1988. Removal of essentially all petroleum products and hazardous wastes in tanks and drums was accomplished from 1988 - 1991. The process that will lead to the complete clean-up of the facility is ongoing. The site was added to the National Priorities List (NPL) in October 1992. Exposure of humans to contaminants in soil and air is thought to have occurred near Petrochem. The source(s) of those contaminants in …


Paleobathymetric Interpretation Of Pleistocene Sediments In The South Padre Island Area, Northwestern Gulf Of Mexico, Using Benthic Foraminiferal Morphology, Karen Ianthe Kruebbe-Belwood Apr 1993

Paleobathymetric Interpretation Of Pleistocene Sediments In The South Padre Island Area, Northwestern Gulf Of Mexico, Using Benthic Foraminiferal Morphology, Karen Ianthe Kruebbe-Belwood

OES Theses and Dissertations

This study tested the validity of using intraspecific variation in benthic foraminifera as a means for determining Pleistocene paleobathymetry. Canonical variate analysis was used as a means for determining visually undetectable but statistically significant differences in the morphology of selected species. Two species, Cassidulina subglobosa and Uvigerina peregrina, were collected from Pleistocene well cuttings from the northwest Gulf of Mexico. The canonical analysis involved comparing the intraspecific variation of these Pleistocene species to their counterparts occurring in the modern Gulf of Mexico, where intraspecific variation was previously analyzed and found to be sufficient to allow detection of bathymetric differences …

Grazing Alfalfa — State Perspective, W. Roy Burris, Garry D. Lacefield Feb 1993

Grazing Alfalfa — State Perspective, W. Roy Burris, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Alfalfa has been grown in Kentucky for many years, but in the last decade, its acreage has increased dramatically- from 208,000 in 1978 to 350,000 in 1981 (Ky. Agri. Statistics Service). Alfalfa is generally thought of as a hay crop but the practice of grazing alfalfa has received considerable attention recently. Much of this interest was generated by "Graze-More-Beef" demonstrations which have been conducted in the state. Demonstrations in which alfalfa was grazed averaged 791 pounds per acre during 1986-1988. Alfalfa's ability to withstand dry weather and its excellent nutritional qualities make it an attractive grazing alternative to fescue - …

Carbon, Nitrogen, And Phosphorus Leaching Rates From Spartina Alterniflora Salt Marshes, R. Eugene Turner Jan 1993

Carbon, Nitrogen, And Phosphorus Leaching Rates From Spartina Alterniflora Salt Marshes, R. Eugene Turner

Faculty Publications

Annual carbon, nitrogen, and phosphorus leachate rates from live Spartina alterniflora Loisel in a Louisiana (USA) salt marsh were estimated to be 200, 14, and 3 g m-2, respectively, and to peak in summer and higher salinit~es. Leachate losses of P, N and C are equivalent to a turnover of live plant tissues of 10, 17 and 49 d, respectively, when submerged, and 148, 250 and 721 d, respectively, when unsubmerged. Plant leachate losses during marsh submergence and non-submergence are nearly equal because release rates are 15x greater during submergence. Nitrogen and carbon concentrations relative to phosphorus are proportionately 4x …

Conflicts In Use: The Impacts Of The Oil And Gas Industry On The Herring Fishery In The North Sea, Cornelia Ann Pasche Jan 1993

Conflicts In Use: The Impacts Of The Oil And Gas Industry On The Herring Fishery In The North Sea, Cornelia Ann Pasche

Marine Affairs Theses and Major Papers

The interaction of the herring (Clupea harengus) with the oil and gas industry in the North Sea is reviewed. The population crash of the herring in the early 1970's and the subsequent closing of that important fishery between 1977 and 1983 has drawn considerable attention to the influences, both biotic and abiotic, affecting the recruitment to the North Sea stock. Current accepted theory points to a change in oceanic current and the subsequent decrease in salinity in the North Sea region, resulting in a change in plankton availability for larval herring as the cause of the recruitment failure during the …


Sheep And Wool Industries Need To Improve Their Performance, Rob Kelly, Tim Marshall Jan 1993

Sheep And Wool Industries Need To Improve Their Performance, Rob Kelly, Tim Marshall

Journal of the Department of Agriculture, Western Australia, Series 4

Today in Western Australia, sheep are run at slightly higher stocking rates, are achieving greater lambing percentages (up JO per cent) and higher wool cuts per animal ( up 0. 6 kg greasy) than in the 1960s. When all components of production are considered, the productivity of sheep fanns has increased by 2. 7 per cent per year over the past 35 years.

The challenge of the next decade is to achieve substantially greater rates of improvement than for past years if the sheep and wool industries are to maintain their significant place in Western Australian agriculture.

Soil Sampling Made Easier, Mike Bolland, Mike Baker

Journal of the Department of Agriculture, Western Australia, Series 4

A new rotary blade soil sampler has taken the hard work out of collecting soil samples from Western Australia's hard-setting soils to test for soil phosphorus levels .

Conceived and developed by Department of Agriculture technical officer Mike Baker, it should enable soil testing to be more widely adopted. Fortunately, the soil calibration tests that were developed using pogo samples can also be used for the new sampler.


Improving Sustainable Production From Water Repellent Sands, Paul Blackwell Jan 1993

Improving Sustainable Production From Water Repellent Sands, Paul Blackwell

Journal of the Department of Agriculture, Western Australia, Series 4

The agricultural management of water repellent ( non-wetting) sands is difficult, and production from them is mostly low. However, there are ways to make them more productive.

Furrow sowing and the incorporation of dispersive clay are two likely methods to make these soils easier to manage, more productive and more profitable than they are now.

This article discusses several aspects of our research on water repellent sands. In addition, some of the costs and benefits of alternative management strategies are outlined.


Seasonal And Annual Variation In Weight And Biochemical Content Of The Zebra Mussel, Dreissena Polymorpha, In Lake St. Clair, Thomas F. Nalepa, Joann F. Cavaletto, Mark Ford, Wendy M. Gordon, Marijo Wimmer Jan 1993

Seasonal And Annual Variation In Weight And Biochemical Content Of The Zebra Mussel, Dreissena Polymorpha, In Lake St. Clair, Thomas F. Nalepa, Joann F. Cavaletto, Mark Ford, Wendy M. Gordon, Marijo Wimmer

United States Department of Commerce: Staff Publications

Zebra mussels, Dreissena polymorpha, were collected monthly from April/May to November in 1990 and 1991 from two sites in Lake St. Clair. The sites were characterized by relatively high and low mussel densities. The following variables were measured: ash-free dry weight (AFDW) per unit shell length (SL), lipid content and classes, carbon content, and nitrogen content. Mussels from the high-density site had a lower AFDW:SL relationship, lower lipid content, and a lower C:N ratio than mussels from the low-density site. Seasonal trends in these variables were consistent between sites and years. AFDW:SL, lipid, and carbon content were highest in …


13.4.8. Options For Water-Level Control In Developed Wetlands, J. R. Kelley Jr., M. K. Laubhan, F. A. Reid, J. S. Wortham, L. H. Fredrickson Jan 1993

13.4.8. Options For Water-Level Control In Developed Wetlands, J. R. Kelley Jr., M. K. Laubhan, F. A. Reid, J. S. Wortham, L. H. Fredrickson

Waterfowl Management Handbook

Wetland habitats in the United States currently are lost at a rate of 260,000 acres /year (105,218 ha/year). Consequently, water birds concentrate in fewer and smaller areas. Such concentrations may deplete food supplies and influence behavior, physiology, and survival. Continued losses increase the importance of sound management of the remaining wetlands because water birds depend on them.

Human activities modified the natural hydrology of most remaining wetlands in the conterminous United States, and such hydrologic alterations frequently reduce wetland productivity. The restoration of original wetland functions and productivity often requires the development of water distribution and discharge systems to emulate …

13.2.11. Increasing Waterfowl Nesting Success On Islands And Peninsulas, John T. Lokemoen Jan 1993

13.2.11. Increasing Waterfowl Nesting Success On Islands And Peninsulas, John T. Lokemoen

Waterfowl Management Handbook

Waterfowl that nest in uplands in the prairie pothole region have had low recruitment rates in recent decades, primarily because of predation. The loss of breeding waterfowl and their progeny has generated interest in management techniques that safeguard incubating hens and their eggs. Developing islands and peninsulas for nesting waterfowl has potential because these sites are naturally attractive to breeding ducks and geese. In fact, dense nesting colonies of ducks developed on some islands when successful females and a portion of their female progeny returned in subsequent years.

Managers have successfully duplicated the beneficial attributes of islands by developing various …


13.4.13. Management And Control Of Cattails, Richard S. Sojda, Kent L. Solberg Jan 1993

13.4.13. Management And Control Of Cattails, Richard S. Sojda, Kent L. Solberg

Waterfowl Management Handbook

The response of wetland vegetation to management can only be interpreted by considering an intricate mix of physiological, ecological, and temporal factors. Because cattail management is important for many freshwater marshes, the purpose of this leaflet is to present autecological principles for such management.

A 50:50 ratio of open water and vegetation is a frequent objective when managing cattail marshes in North America. When a particular marsh has been extensively flooded for some time and few cattails remain, managers may wish to foster more cattails to develop such hemi-marsh conditions. The reverse is followed when a marsh is dominated by …


Seasonal Water Regimes And Leaf Litter Processing In A Wetland On The Swan Coastal Plain, Darren Ryder Jan 1993

Seasonal Water Regimes And Leaf Litter Processing In A Wetland On The Swan Coastal Plain, Darren Ryder

Theses : Honours

The effect of seasonal or permanent inundation on the processing of leaf litter from two competing emergent macrophytes Baumea articulata and Typha orientalis was examined at Lake Jandabup, a seasonal wetland on the Swan Coastal Plain. The loss of organic matter from leaf packs was used to quantify leaf litter processing. The contributions made by microorganisms and macroinvertebrates in processing were also assessed. Leaf packs exposed to seasonal inundation (defined as those areas exposed to alternate wetting and drying) had significantly higher losses of organic matter after six months than those permanently inundated for the same period. The presence of …


13.2.2. The North American Waterfowl Management Plan: A New Approach To Wetland Conservation, Angela V. Graziano, Diana H. Cross Jan 1993

13.2.2. The North American Waterfowl Management Plan: A New Approach To Wetland Conservation, Angela V. Graziano, Diana H. Cross

Waterfowl Management Handbook

The decline of waterfowl populations and the loss of wetlands are high-ranking environmental concerns in North America. The importance of these issues is reflected in an ambitious wetland recovery plan, the North American Waterfowl Management Plan. Signed in 1986 by the U.S. and Canadian federal governments, the plan features specific strategies to reverse the declines in waterfowl numbers and wetland acreage. The goal is to restore waterfowl populations to a level common to the 1970’s by improving and securing long-term protection of 6 million acres (2.4 million ha) of habitat in 34 areas of major concern.

The key to achieving …


13.3.14. Detrital Accumulation And Processing In Wetlands, Patrick A. Magee Jan 1993

13.3.14. Detrital Accumulation And Processing In Wetlands, Patrick A. Magee

Waterfowl Management Handbook

Wetlands are among the most productive ecosystems on earth (Fig. 1) and are often characterized by lush growths of hydrophytes. However, direct consumption of wetland plants by animals is relatively low, and, therefore, much of the biomass and energy assimilated by hydrophytes becomes detritus or senesced plant litter. Nutrients released by detritus into the water and soil are assimilated by microorganisms, algae, plants, and small aquatic animals. Through this process, energy is transferred from detritus to other biotic components of a wetland. Plant litter ultimately decomposes.

Litter processing is regulated by environmental factors, microbial activity, the presence and abundance of …
