Ichthyofaunal Diversification And Distribution In Jane's Creek Watershed, Randolph County, Arkansas, Cheryl Lynn Fowler, George L. Harp

Journal of the Arkansas Academy of Science

The purposes of this study were to determine the qualitative and quantitative distribution of fishes in the Jane's Creek watershed. Jane's Creek is a clear, spring-fed Ozark stream in northeastern Arkansas. A knowledge of the ichthyofauna of this stream prior to a long-range impoundment is of significance to the natural history of Arkansas. Jane's Creek and its tributaries were found to be alkaline, with no measurable turbidity, and to have low levels of carbon dioxide. Dissolved oxygen values ranged from 6.1 to 16.0 ppm. Only slight differences in physicochemical conditions were noted among stations and between pool and riffle areas …

The Ecology Of Marron Cherax Tenuimanus (Smith) Introduced Into Some Farm Dams Near Boscabel In The Great Southern Area Of The Wheatbelt Region Of Western Australia, Noel M. Morrissy Dr

Fisheries Research Bulletins

A large scale survey was conducted in 1968 and 1969 over the inland area of the southwest of Western Australia to establish the degree of success of introductions of marron, Cherax tenuimanus (Smith), in small, private, turbid farm dams. The results of this investigation stimulated further research, described in this paper, on marron in this type of water

Fisheries Report No 15 - The Western Rock Lobster Fishery 1972 - 1973, G. R. Morgan, E H. Barker

Fisheries Research Reports

The fishery for the western rock lobster* is one of the most important single fisheries in Australia and an important export earner for the State. The fishery is governed by a complex set of regulations which have been reviewed by Bowen (1971) and which are designed to limit the total effort to acceptable levels and to enforce a legal minimum size. It is thus important to constantly monitor the state of the fishery both to ensure that the effort is remaining within the accepted limits and that the regulations are adequately performing their function of maintaining reasonably stable catches. Inherent …

Review Of Curassows And Related Birds, Paul A. Johnsgard

Papers in Ornithology

To contemplate the appearance of a new book dealing for the first time with an exhaustive coverage of an entire avian family is to evoke an excitement that is all too rare an occurrence for most ornithologists. This excitement is enhanced when the bird group is one of the least studied and yet, evolutionarily speaking, most significant of the galliform families, and when the authors are as well known and highly respected as Delacour and Amadon. Anticipation reaches its apogee when the contributing artists are as competent as Albert E. Gilbert, George M. Sutton, and David Reid-Henry. After reading the …

The Taxonomy And Relationships Of The Northern Swans, Paul A. Johnsgard

Paul Johnsgard Collection

The recent (1972) publication of the Wildfowl Trust's book The Swans has brought together an unprecedented array of information on all of the swans of the world, and makes it desirable to raise once again the question: how many species of northern swans are there, and what are their evolutionary relationships to one another? Delacour (1954) suggested the comprehensive vernacular name 'northern swans' to distinguish 'the various knobless white swans which breed in or near the Arctic parts of the northern hemisphere' from the Mute Swan (Cygnus olor) and the three southern hemisphere swans. The northern swans have …

Beef Marketing As A Guide To Production Techniques, D J. Barker

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

Until about a year ago beef was in strong demand. Almost anything was marketable at favourable prices and good profits could be made even if the production process was wasteful in some respects.

Now the tide has turned. The demand for beef is weak, prices are low and some types of beef are virtually unsaleable. Now more than ever it is important to look critically at the factors which affect beef quality and to seek ways of reducing waste in both feed used and end products marketed.

This article examines production and marketing of beef and points out some inadequacies …

Development Of A Selective Bait For Rabbits, A J. Oliver, S. H. Wheeler

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

It has long been recognised that a means of killing rabbits selectively in the presence of stock would be a major advance in rabbit control. It would enable a whole farm to be treated for rabbit control at one time, saving operational costs and cutting down reinfestation of rabbits into treated areas from untreated areas.

A literature search and some pilot trials indicated that indandione derivatives were more toxic to rabbits than to ruminants.

Pindone (2- pivalyl-l,3-indandione) was selected for evaluation.

Influence Of Nutritional Regime On Age At Puberty In Gilts, P. J. Cunningham, C. H. Nabor, Dwane R. Zimmerman, E. R. Peo, Jr.

Department of Animal Science: Faculty Publications

Age at puberty was determined for 205 Gene Pool gilts; 68 fed a 10% protein diet (HLC) consisting of high-lysine corn, minerals and vitamins and 137 fed a 14% protein corn soybeam meal diet (CS). Gilts fed the CS diet reached puberty 18.7 days earlier than gilts fed the HLC diet. Use of post-weaning daily gain as a covariable reduced the difference between diets to 9 days. The pooled within diet regression of age at puberty on post-weaning gain was -22.75 days per kilogram. The correlation between pubertal age and daily gain was significantly higher on the HLC diet (-.30 …

Annual ('Wimmera') Ryegrass Toxicity, Geoffrey A. Pearce, O. M. Goss, P. H. Berry, J. L. Wise

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

Because annual ryegrass is one of the most widespread pasture plants in Western Australia, annual ryegrass toxicity is a threat to livestock in many agricultural areas—even though the area now affected is small.

The problem is being intensively studied by the Department of Agriculture and a working group has been set up to investigate potential control measures.

In this article the group reviews the problem and reports progress in its investigations to the end of 1973.

The Effects Of Changing Flock Structure On The Amount And Type Of Turn-Off From Sheep Flocks, T Marshall

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

In the past the proportion of mated ewes in Western Australia's sheep flocks carried through summer has averaged about 40 per cent and sheep meat production has been basically lamb and old mutton.

If the proportion of mated ewes was lifted to an average of around 50 per cent and wethers were sold off at an average of about 2 1\ 2 years old, there would be substantial increases in sheep meat production. The extra meat produced would be young sheep meat ideally suited for table meats for consumers in W.A. and in many overseas countries.

As a result of …

Bulletin No 3887 - Cattle Yard Construction, Western Australian Department Of Agriculture

Bulletins - 3000 - 3999

Good cattle yards allow animals to be handled quietly, safely and efficiently. If yards are well designed, animal uneasiness is minimised and so, too, are frayed tempers.

This bulletin outlines general points of cattle yard design and construction. There are many and varied cattle yard designs in use—many good ones and some bad ones. This bulletin should help in avoiding the bad ones.

The Medina Pig Research Station, Department Of Agriculture, Western Australia

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

Before the Department of Agriculture's Medina Pig Research Station was established in 1964, pig production research had been carried out on Denmark Research Station, Muresk Agricultural College and in some commercial herds.

However, with increasing specialisation in the pig industry better facilities were needed. Medina Research Station provides such facilities, allowing it to carry out research to provide detailed information of immediate practical value for both extensive and intensive pig production enterprises.

Effect Of Dietary Calcium And Phosphorus Level Upon Calcium, Phosphorus And Nitrogen Balance In Swine, P. E. Vipperman, Jr., E. R. Peo, Jr., P. J. Cunningham

Department of Animal Science: Faculty Publications

Three metabolism trials were conducted to determine the effects of dietary calcium and phosphorus level upon calcium, phosphorus and nitrogen balance in growing swine. The nine pigs in each trial averaged 22.6, 25.2 and 26.5 kg initially for trials 1, 2 and 3, respectively. The diets contained three levels of calcium and three levels of phosphorus and were rotated among the pigs in the three trials. Feed intake was adjusted to metabolic size.

Effects Of Mississippi Delta Flooding On Spider Populations, Peggy Rae Dorris

Journal of the Arkansas Academy of Science

The Mississippi Delta flooded in the spring of 1973. Spider collections made in a Delta area of Mississippi in 1972 are compared with those made in 1973 during the flood and after it subsided. Because many egg cases and immature and mature spiders were destroyed by the flood, the spider population was diminished.

Effects Of Fungus-Fermented Soybeans On Broiler Growth And Life Cycle Performance Of Coturnix Quail, Cheong Choo Chah

Electronic Theses and Dissertations

Despite the extensive data that have accumulated on the detrimental effect of molds on the growth of farm animals, very little is known as to the beneficial role of fungi in animal feed. Recent studies at South Dakota State University research laboratories revealed, however, that only 164 of 392 strains of Aspergilli were found to be toxic. When the cultures were grown on sterile soybeans or wheat, some of the tested cultures exerted positive effects on growth of chicks and mice. Hence, the investigations reported herein were initiated to obtain further information on those cultures beneficial to chick performance and …

Electronic Theses and Dissertations

In experiment I a series of in vitro buffer and rumen fermentation studies were conducted to evaluate protein solubility at pH 6.8 and pH 2.5 (with pepsin) and ammonia production from whey protein concentrates (WPC, 55% protein) treated with 0, .25, .5, 1.0, and 3% formaldehyde; 1, .5, 1.0, 2.0, 3.0, and 6% tannic acid; and 0, 1, 2, and 3 hr of heat treatment at 104 C. Protein solubility and ammonia production from casein treated with 0, .5, 1.0, and 3% formaldehyde and 0, .5, 1.0, and 3% tannic acid were also studied. All levels of formaldehyde treatment of …

Light And Electron Microscope Study Of The Mitotic Apparatus Of The Ring-Legged Earwig, Euborellia Annulipes (Lucas), Vonnie R. Prentice, William L. Evans

Journal of the Arkansas Academy of Science

The mitotic apparatus in dividing cells of the ring-legged earwig is composed of the cell center or pole, chromosomal fibers, continuous fibers, and chromosomal and background structure. Parts from cellular elements such as Golgi membranes, endoplasmic reticulum, and nuclear envelope as well as whole mitochondria associate with the spindle microtubules to produce the diffraction pattern of the spindle fibers as seen with the light microscope. The microtubules of the chromosomal fibers attach independently and demonstrate the diffuse nature of the centromere or polycentric condition of the chromosomes.

Defensive Behavior Of The Hognose Snake (Heterodon Platyrhinos), Brenda S. Hemken

Masters Theses

Fourteen out of sixteen Heterodon platyrhinos eggs were hatched in late August, 1973. The immature snakes were manually stimulated and the resultant bluffing and death-feigning behaviors were observed. All of the experimental snakes bluffed, but only three out of ten feigned death. The major components of the bluffing behavior are spreading the neck, hissing, and striking. Death-feigning is preceded by contortions and shows variations in the positions of the mouth and tongue. The newly-hatched snakes exhibited both bluffing and death-feigning, indicating that the behaviors are innate.

Status Of The Wild Turkey In Southwestern Illinois In 1970, Robert Merle Cottingham

Masters Theses

Wild-trapped turkey were first released in southwestern Illinois in 1959. This, and subsequent releases have established a huntable population of wild turkey in the area. Until 1970, no evaluation of the status of the bird had been made. This study was conducted in June, July, August and September, 1970, to determine the distribution, productivity and relative abundance of the wild turkey in Alexander, Jackson, Union and Williamson Counties and to make recommendations for future management of the population. Information was supplied by rural mail carriers, Illinois Department of Conservation and U. S. Forest Service personnel and local residents together with …

An Introduction To The Ethology Of Citellus Variegatus, John W. Bell

Masters Theses

The above ground activity of the rock squirrel Citellus variegatus between November 6, 1972 and May 1, 1973, is described. This is a non-colonial species. Recognition was established between siblings by a nose to nose contact. In foraging they utilize almost any edible material available and during this time of year foraging is most intense between 11:00 a.m. and 4:00 p.m. Vocalization was limited to alarm calls, which brought the other squirrels to the top of the rocks to become alert, and squeals. Hibernation varied in length depending in part on the elevation and in some did not occur at …

Helminth Parasites Of Illinois Wild Turkeys, James W. Jackson

Masters Theses

Viscera from 69 wild turkeys (Meleagris gallopavo silvestris) collected from Jackson, Union and Alexander counties, Illinois, were examined for helminth and coccidian parasites. A total of eight species of parasites was found, all in the alimentary tract. The coccidian parasite Eimeria sp. was found in 9.6% of birds examined. The nematodes Heterakis gallinarum, Ascaridia galli and Ascaridia dissimilis were found in 13.2%, 27.9% and 48.5% respectively of all birds examined. Three species of cestodes, Raillietina williamsi, Metroliasthes lucida and Hymenolepis sp., were recovered from 41.1%, 27.9% and 1.4% respectively of birds examined. One species of trematode, …
