Campaniform Sensilla Patterns On The Wings Of Drosophila, Charles L. Hamrum, Arthur W. Glass, Vern Sisson

Journal of the Minnesota Academy of Science

Campaniform sensilla have been described from the wings, mouthparts, legs, and other parts of the insect body. These small sense organs were known under several terms until Berlese ( 1909) applied the term "campaniformi" because of their dome, or bell-shaped character. Numerous functions have been suggested for these organs which seem to be stress receptors of some sort. Very few attempts have been made to utilize these sensilla as taxonomic characters.

Some Aspects Of Sport-Fishing Yields From Minnesota Lakes, Warren J. Scidmore

Journal of the Minnesota Academy of Science

The value of angling as a recreational feature is generally recognized by everyone in Minnesota. About one adult Minnesotan in three fishes, to say nothing of those younger. than 16 who need no fishing license. The impact of this sport fishing on the economy of the state is considerable. The 1.3 million resident and non-resident anglers spend some 100 million dollars annually to catch fish (Scheftel, 1958) and the annual sportfishing catch of fish from some 2 million acres of Minnesota fishing waters has been conservatively estimated at about 25 million pounds (50 million fish) (Moyle, 1958).

Larval Trematodes Of Fresh-Water Snails Of Lake Itasca, Minnesota, Omer R. Larson

Journal of the Minnesota Academy of Science

The purpose of this study was to determine the cercariae present in nine species of aquatic snails of Lake Itasca, Minnesota. Although Cort (1914), and Faust (1917) initiated cercarial survey studies in North America, no comprehensive survey has been reported from Minnesota. Sporadic reports since 1928 have described the occurrence of twenty-two species of cercariae in our state. This report adds seven species to the known cercarial fauna of Minnesota.

New Distributional Records Of Some Minnesota Fishes, Frank Nordlie, James C. Underhill, Samuel Eddy

Journal of the Minnesota Academy of Science

Minnesota is almost unique in that its waters drain by three divergent courses: the Red River to the Arctic, the Great Lakes to the Gulf of St. Lawrence and the Mississippi River to the Gulf of Mexico. The close proximity of the headwaters of these several drainages present opportunities for certain species to move from one basin to another. Species restricted to the Arctic basin have their southern limits in northern and western Minnesota. Many eastern and southern species have their northern and western limits within the state. In spite of the fact that intensive collecting has been carried on …

Intra-Specific Variation In The Common Shiner, Notropis Cornutus Frontalis (Agassiz) From Minnesota And South Dakota, James C. Underhill

Journal of the Minnesota Academy of Science

The voluminous literature relating to intra-specific variations in fishes has been reviewed by Hubbs (1934, 1940), Tanning (1952), Lindsay (1953) and others. A majority of the workers have supported the interpretation that the variation is influenced by various environmental factors, primarily the temperature during the pre-fry stages of development. Certain of the meristic characters which show such variability have been generally used in identifying various races of minnows. If such characters as the number of anal fin rays or scales in the lateral line are easily influenced by the environment, their usefulness in defining races is certainly open to question. …

Deer Studies At Camp Ripley, Minnesota, Bernard A. Fashingbauer

Journal of the Minnesota Academy of Science

The white-tailed deer has been studied by wildlife biologists throughout its range. Additional information is required for improved management of deer in Minnesota and elsewhere. With the permission and cooperation of military authorities, deer studies have been established within the seventy square mile Camp Ripley Military Reservation and State Game Refuge near Little Falls, Minnesota. The accessibility of the area, large deer population, and habitat conditions offered an excellent location for the proposed studies. In addition, the relatively complete control of hunter use of the Camp was a decided advantage in conducting big game research.

Some of the research work …

The Use Of Tree Rings To Date Beaver Colonies, J. Benton Kettleson

Journal of the Minnesota Academy of Science

In 1946, I began the periodic observation of several beaver colonies located near my family's summer cabin, in Crow Wing Co., central Minnesota. From 1953 to 1956, a detailed study of the colonies was conducted as a Junior Academy of Science project. During this period, several new colonies were established and many of the older ones abandoned. A study of aerial photographs, followed by a ground check on foot or by canoe, turned up many other beaver colonies, some active at the time of discovery and many apparently long deserted.

In searching for a method of ascertaining when these workings …

Relation Of Heart Girth To Weight In Holsteins And Jerseys, H. P. Davis, W. W. Swett, W. R. Harvey

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Body weight is the one measurement most extensively used to evaluate growth, condition, and value for beef, and as a basis for calculating feed requirements for cattle. Weight can be determined readily by scales but unfortunately scales of a capacity adequate for weighing cattle are not always available. Thus there is a real need for a basis of estimating weight from some body measurement that can be obtained easily and at a minimum of cost and time. It is the aim of this study to utilize additional data now available to increase further the accuracy and reliability of estimating weight …

List Of Registered Stock Foods And Stock Licks 1960-61, H G. Cariss

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

All foods for stock sold in Western Australia are required by the Feeding Stuffs Act, 1928-1955, to be registered annually with the Department of Agriculture.

For the purposes of the Act, "Food for Stock" includes stock licks, which in turn embrace all preparations claimed to supply or primarily intended to supply mineral matter to stock.

Correcting Cobalt Deficiency, Laurence C. Snook

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

COBALT is essential in the food eaten by sheep and cattle. As little as one part of cobalt in 10,000,000 parts of food appears to be adequate.

But if this mere trace is missing, ruminants will waste away and die, even when the feed appears excellent In every other way.

Third West Australian Random Sample Egg Laying Test : 1959-1960, R H. Morris

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

AS part of the poultry improvement plan for Western Australia, the Department of Agriculture inaugurated a random sample laying test for commercial grade chickens at the Poultry Research Station, Herdsman Lake, in 1957.

The results of the first test appeared in the May-June, 1959 issue of the Journal of Agriculture and those of the second test in the June, 1960 issue.

Swine Erysipelas : A Newly Reported Disease Of Pigs In Western Australia, M R. Gardiner

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

RECORDED in Western Australia for the first time last year, swine erysipelas is a potential menace to the pig raising industry.

This preliminary description is given to help farmers recognise its occurrence. I t is not known how widespread the disease might be, and farmers' co-operation is needed to estimate its extent.

Any suspected cases should be reported without delay.

HYDROCYANIC or prussic acid poisoning is a serious and not uncommon ailment of ruminants, and may be a cause of rapid death when pasture plants capable of developing dangerous levels of the poison are being grazed.

Is Your Water Supply Safe?, D C. Mickle

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

THERE can be no doubt in anyone's mind that the need for a clean, safe and adequate water supply is essential for the production of high quality milk and cream.

It naturally follows, that, even though every possible care has been taken in an endeavour to produce clean, germ-free milk and cream, contamination by bad water can render these efforts void.

Poisoning Rabbits From The Air, C D. Gooding

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

AERIAL baiting gives spectacular kills of rabbits in country which cannot be effectively treated by conventional means, and has been widely adopted in New Zealand and other States in Australia.

Here Mr. Gooding reports on developments in aerial baiting in Victoria, and suggests practical applications in Western Australia.

Avoid Losses From Poison Plants, Robert Dunlop Royce

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

E VERY country in the world has its poisonous plant problems, but in Western Australia we have more than our share.

Farmers in "Poison" districts can avoid serious stock losses if they can recognise dangerous poison plants, and have a knowledge of how the concentrations of toxic substances in these plants change with the seasons.

In this article, R. D. Royce, Officer in Charge of the Botany Branch, outlines the principles involved.

Feeding For Egg Yolk Colour, P Smetana

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

ON July 3, 1961, the Western Australian Egg Marketing Board commenced paying a bonus to producers for yolk colour.

This is an extremely important step in the marketing of eggs and should have a widespread beneficial effect on the poultry industry of this State.

Automatic Waterers For Day Old Chickens, P Smetana, W. Ward

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

ONE of the most tedious and time consuming tasks on a poultry farm is the provision of water to chicks from day old up to the age of three or four weeks.

Most poultry farmers use half-gallon glass fonts with metal bases for the first few weeks, until the chicks are old enough to use the automatic watering system usually situated along one wall of the brooder house.

This cumbersome glass font system can be replaced by the cheap and easily installed automatic watering system described below. This system has already been adopted by several local poultry farmers.

Let's Look At Dairying, Maurice C. Cullity

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

FOR several years there has been a lot of gloomy forebodings about the future of the dairying industry.

It has been said that there is a drift from dairying; the industry is declining; or even that it is finished.

The Open Range System Of Pig Farming, S R. Dunstan

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

THERE are several satisfactory systems which can be employed in planning a piggery, but under West Australian conditions, the paddock system has much to commend it.

Grazing admits an animal to the healthy influences of sunlight and stimulates exercise. The digestive processes of the pig are also stimulated and this helps to bring about more efficient utilisation of the feed.

Correspondence About "Evolutionary Relationships Among The North American Mallards", Allan R. Phillips, Paul A. Johnsgard

Papers in Ornithology

The confusing leading article of the 1961 Auk calls for comment. Despite his title, "Evolutionary Relationships among the North American Mallards," the author discusses primarily geographic distributions, population sizes, egg-white proteins( !), and certain behavioral patterns. Maps are based on ". . . the literature, personal communications, and the major United States collections," " . and from additional sight and specimen records available to me"; yet only two museums other than Cornell University are mentioned in the acknowledgments. These maps show many records of platyrhynchos far to the south; sometimes (Figure 1) the reader must search hard for any hint …

Incubation, R V. Vagg

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

TH E artificial incubation of eggs is not a recent innovation. For many centuries, some species of birds—our mallee-hen being a typical example—have hatched out their eggs by the heat generated in mounds of decaying vegetation.Furthermore, they have shown considerable skill in maintaining the mounds at uniform temperatures throughout the hatching period.

A number of reptiles employ similar methods to hatch their eggs, although in these instances there does not seem to be the same need for carefully-controlled temperatures

The Taxonomy Of The Anatidae—A Behavioural Analysis, Paul A. Johnsgard

Paul Johnsgard Collection

Delacour & Mayr's (1945) classic revision of the Anatidae took waterfowl behaviour into account to a much larger degree than had any previous classifications of the group. However, their utilization of behaviour was primarily at the tribal and generic levels, and no real attempt was made to use behaviour for determining intrageneric relationships. Thus far only Lorenz (1941, 1951-1953) has seriously attempteq this with waterfowl, and his analysis of the relationships within the genus Anas (sensu Delacour & Mayr) has provided a remarkable insight into the evolution of this group. I have attempted to expand Lorenz's behavioural delineation of relationships …
