Free Amino Acids In A Cave Beetle Darlingtonea Kentuckensis Valentine (Coleoptera: Carabidae), R. J. Sperka

International Journal of Speleology

Free amino acids of Darlingtonea kentuckensis were investigated by two-dimensional, thin-layer chromatography on Silica Gel G. Thirteen amino acids which could be identifìed (alanine, glutamic acid, glycine, histidine, isoleucine and/or leucine, lysine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine and valine) and seven unidentified ninhydrin-positive spots were found. Beta-Alanine, alpha-amino-butyric acid, arginine, aspartic acid, cystine, hydroxyproline and methionine were not detected. No difference was observed in the free amino acids with respect to sex of beetle, time after feeding and method of sample preparation.

Subterranean Crustacea Decapoda Macrura Collected By Mr. L. Botosaneanu During The 1973 Cuban-Roumanian Biospeological Expedition To Cuba, L. B. Holthuis

International Journal of Speleology

During the 1973 Cuban Romanian Biospeleological Expedition to Cuba 5 species of cavernicolous Decapod Crustacea were collected: the Palaemonidae Troglocubanus gibarensis Chace, T. eigenmanni (Hay) and Macrobrachium faustinum lucifugum new subspecies. The second of these species now is reported for the first time from Isla de Pinos. The third form proved to be a new subspecies of Macrobrachium faustinum (De Saussure), a freshwater shrimp which is widely distributed in the West Indies. The new subspecies is not only known from Cuba, but also material from Jamaica, Curacao and Bonaire is reported. A new locality is reported for Barbouria cubensis (Von …

Measurement Of Wind-Driven Currents In A Lagoon, W. K. Schneider, P. S. Dubbelday, T. A. Nevin

Ocean Engineering and Marine Sciences Faculty Publications

Knowledge of the circulation processes and patterns of lagoonal waters is of major importance if their overall biological and physical characteristics are to be more completely understood. In addition, such circulation processes and patterns must be considered in the development of pollution controls. The Indian River actually is a lagoon since it is separated from the ocean by a narrow strip of land; it is moderately saline and has a limited number of inlets. There is visible movement of these waters; however, no evidence of defined circulation processes or patterns has been found reported in the literature.

Some Concepts In Rangeland Management, R B. Hacker

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

The arid and semi-arid zones of Australia occupy about 75 per cent of the land mass. The pastoral industries are located within these zones and, although productivity per unit area is low, the region nevertheless constitutes one of the nation's valuable renewable resources.

If properly managed, such a resource may be maintained as a productive asset indefinitely.

Samphire For Waterlogged Salt Land, C V. Malcolm, G. J. Cooper

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

For non-waterlogged and mildly waterlogged salt land a number of salt-tolerant shrubs may be used for forage production.

Areas which are highly saline and regularly waterlogged are not suited to these shrubs. However, during trials with shrub species, samphires (Arthrocnemum spp.) were found to volunteer and grow well on these sites.

Research into the use of samphires has shown that it is possible to harvest seed and obtain a seed sample suitable for sowing through a drill. Established samphire stands provide useful grazing in many parts of the Western Australian wheatbelt.

Dairying In W.A., Department Of Agriculture And Food, Western Australia

Bulletins - 3000 - 3999

Western Australia has a small dairy industry compared with its other rural production. However, the industry has consolidated over recent years.Tree clearing and pasture development on existing holdings and the amalgamation of small dairy farms has led to a rapid increase in the area of pasture per farm. The trend in Western Australia is towards bigger herds, more efficient dairies, more fodder conservation and increasing production per cow and per hectare. Commercial dairy farming in Western Australia is confined to the south-western corner of the State, south of Perth, extending in a 50-kilometre-wide strip along the coast to 50 kilometres …

Forage Production From Shrubs On Saline Land, C V. Malcolm

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

In the first volume of the Journal of the Department of Agriculture in the year 1900, the results of experiments at Tulare Experiment Station in California on the growing of Australian saltbushes are reported.

Seed was first sent from Australia by Baron von Mueller in June, 1881. Three species of saltbush (A. semibaccata, A. numularia and A. vesicaria) are all reported to have grown well.

Although C. A. Gardner in 1929 suggested the growing of saltbushes for forage, the earliest and clearest recommendations are those of Teakle and Burvill in 1945.

Early research tended to concentrate mainly on the possibility …

A Field Study Of Infiltration On Various Agricultural Soils, Stephen J. Stephen

Theses and Dissertations (Comprehensive)

The purpose of the study was to ascertain if infiltration and temperature varied significantly among the selected soil types of the Smithfield, Otonabee, Wendigo and Farmington Series. These data were gathered from field tests performed during the summer months in Ontario and Victoria Counties.

A stopwatch was used to measure the number of seconds that were required for 0.8 inches of water to disappear into the soil inside a 4 inch diameter single ring infiltrometer which had been placed one inch into the soil surface. The soil temperature was recorded at the same time.

The sites were chosen by stratified …

Pesticide Effects In A Simulated Soil Ecosystem, Raymond J. Samp

Masters Theses

The screening of pesticides to determine which were most inhibitory to bacteria was accomplished by testing the effects of 10 pesticides on 9 different organisms using the disk assay method. Results showed that Gram positive bacteria were more sensitive to all pesticides tested than were the Gram negative bacteria. In addition, the hormone herbicides were found to be the most inhibitory to these bacteria and 2,4-D (2,4-dichlorophenoxyacetic acid), a hormone herbicide, was chosen for subsequent in vivo studies.

A soil perfusion apparatus was used to determine the effects of 2,4-D in a typical soil ecosystem. Bacterial plate counts and nutrient …

The Water Quality And Benthic Macroinvertebrate Fauna Of Lake Charleston, Coles County, Illinois, Paul Barding

Masters Theses

The benthic macroinvertebrate fauna and 15 water quality parameters for five sites on Lake Charleston, Coles County, Illinois were examined for 26 weeks from March 14 through September 5, 1974. None of the water quality parameters studied showed sufficient deviations at any particular area on the lake to merit demarcated water quality zonation. The lake, with its continuous mixing and shallow depth, represented a fairly stable and continuous environment. The benthic macroinvertebrate fauna was determined as fairly diverse and some indication of seasonal variation was apparent. No significant compositional variation over different areas of the lake was found, also indicating …

Conodonts Of The Mecca Quarry Shale, Timothy Charles O'Neill

Masters Theses

Conodonts were found to be abundant in the Middle Pennsylvanian, Mecca Quarry Shale, Parke County, Indiana. Nine forms were identified in this black fissile shale from a locality along Montgomery Creek near the town of Mecca. These elements are: Hindeodella parva, Idiognathodus delacatus, Gondolella sp. a, Ozarkodina delacatula, Lonchodina clarki, Ligonodina typa, Lonchodus simplex, Metalonchodina bidentata, and Neoprioniodus conjunctus.

Ratios of elements to each other were determined and used to arrive at an idea of what conodont assemblages were present. At least three asemblages are presented; Scottognathus, Duboisella, and Illinella …

Effect Of Temperature On Algal Removal By Alum Coagulation, Muhammad Anis H. Al-Layla, E. Joe Middlebrooks, Donald B. Porcella

Reports

Questions about the effect of temperature on algal cell coagulation and the relationships between algae removal and temperature, alum dosage, paddle speed, flocculation time, and settling time are answered. The investigations consisted of two series of tests: Studies on algae cultured under laboratory control, and algae in wastewater stabilization ponds. The jar-test technique was used for the coagulation of algal suspensions by alum. Coagulation of algae is caused mainly by the insoluble flocs of aluminum hydroxide. Other aluminum species also have coagulative properties but are far less effective. The destabilization of algal colloids results from enmeshment within the hydroxide precipitates, …

KWRRI Research Reports

Samples of water, bottom fauna, and fishes were collected from 66 stations in the Salt River and one of its principal tributaries, the Beech Fork and its tributary, the Chaplin River, Kentucky. Precipitation ranged from 38.86 inches (1969) to 58.04 inches (1970), an increase of nearly 50 percent with marked fluctuations in discharge. Intensive comparisons of phosphates, sulfates, specific conductance, total alkalinity, total hardness, and turbidity showed the streams to be relatively clean and healthy. Nearly 300 different kinds of benthic organisms and other macroinvertebrates have been collected and identified from the basin. Detailed studies of caddisflies and stream drift …

Crop Depredations By Waterfowl In Wisconsin, Richard A. Hunt, James G. Bell

Bird Control Seminars Proceedings

On December 5, 1965 the Governor of Wisconsin signed into law a statute permitting claims against the State for damages to crops by wild geese and ducks. This law had been rushed through the legislature in the wake of a rash of crop depredation complaints caused by Canada Geese in their off-refuge feeding flights from the Horicon National Wildlife Refuge. This paper reviews our experiences with waterfowl depredations in the development of a cooperative program by State and Federal wildlife agencies that has held a potentially serious wildlife problem to a minimum of financial losses and public relations concern.

Application Of An Avian Bioenergetics Simulation Model To Red-Winged Blackbird - Crop Relations, John A. Wiens, Melvin I. Dyer

Bird Control Seminars Proceedings

The impact of bird populations upon the properties or processes of ecosystems is mediated through patterns and magnitudes of energy flow. This impact may be either direct, by processing of large quantities of energy or nutrients, or indirect, through feedback control of other ecosystem rate processes or components. In either case, however, the impact is a result of the population dynamics and the pattern and magnitude of food consumption of the birds. Recent research by several groups points to a relatively small direct impact on birds on most natural ecosystems (Wiens 1973). Impact through feedback control, a more difficult relationship …

Night Flight Across A Blue Sky: Prognostics, Robert H. Giles Jr.

Bird Control Seminars Proceedings

The purpose of this presentation is to gain new perspectives on pest control and related phenomena. Some will call it “blue sky.” I would claim it informal futuristics. Systems men call such efforts feedforward; others grandify it with “prognostics.” Some say prognostics is one of the leading challenges of the day. We must anticipate future developments and imagine or invent new alternatives as a background for rational choice. The activity can influence today’s decisions, modify our concepts of risks and probable payoffs, and can help those of us who ask: “What am I really doing; what should I be doing?”

Plant-Animal Interactions: The Effects Of Redwinged Blackbirds On Corn Growth, Melvin I. Dyer

Bird Control Seminars Proceedings

Red-winged Blackbirds (Agelaius phoeniceus) in agricultural crops likely create the worst possible images in the minds of various segments of our society today. To some there is only repulsion, which results in desire for total annihilation of Red-wings (by many agriculturists); while to others there is only attraction, which results in desire to leave the situation absolutely alone (by conservancy minded purists). The great middle ground includes those who vascillate back and forth, between these extremes, those who are not cognizant of the problems, and those that do not care. This picture apparently is a common problem for our wildlife …
