Ground Squirrel Control In California, Richard H. Dana

Vertebrate Pest Conference Proceedings: 1st (1962)

The control of ground squirrels in California is important in two ways. First, it is necessary to prevent destruction of agricultural crops. Second, it is important from a health standpoint where rodent-borne diseases have been demonstrated to be present. Ground squirrel control in this State is the responsibility of the county agricultural commissioners, the State Department of Agriculture and on Federal lands the Bureau of Sport Fisheries and Wildlife. Most control measures are concerned with but two of the nine species of ground squirrels found in California. These include four subspecies: Beechey ground squirrel (Citellus beecheyi beecheyi), Douglas ground squirrel …

Controlling Muskrats, Rollo E. Talbert

Vertebrate Pest Conference Proceedings: 1st (1962)

Today damage attributed to muskrat activities occurs both to irrigation systems and waterways serving agricultural interests as well as to power company installations, waterfowl refuges and hunting clubs. Direct damage or destruction of agricultural crops is relatively minor although the muskrat is known to feed on a variety of produce including ear corn, alfalfa, clover and carrots and frequently will cut a rather wide swath of rice near water control boxes separating rice paddies. The brief activities of fur trappers appear to have little significance as applied to alleviating these losses, so we are forced to recognize that we will …

Linnets, Horned Larks, Crowned Sparrows And Woodpeckers, James W. Koehler

Vertebrate Pest Conference Proceedings: 1st (1962)

CALIFORNIA HOUSE FINCH Carpodacus mexicanus frontalis: Depredations. In California the linnet is an abundant resident throughout the State wherever food and water are available. It is most numerous on the valley floors and in the foothills where man's development has created an extensive favorable habitat. The linnet is primarily a seed eater and before the introduction of domestic fruits into California probably lived largely on weed seeds. Linnets attack the ripening fruit of the apricot, cherry, peach, pear, nectarine, plum, prune, avocado, grape, apple, fig, strawberry, blackberry, raspberry and many others. They disbud almond, apricot, pear, peach, plum, prune and …

Controlling Yellow-Billed Magpies (Pica Nuttalli), Rex Lynda Ii

Vertebrate Pest Conference Proceedings: 1st (1962)

The yellow-billed magpie is a little smaller than the American or black-billed magpie, but the difference in size is very slight. The birds look exactly alike, except one has a black beak and the other has a yellow bill and a bit of yellow skin back of the eye.There are concentrated populations in the Los Banos area, Gustine area, and along the course of the Merced River comprising about 19,100 acres. They are occasionally seen in other areas of the County, but only infrequently observed in the southwestern portion of the County. The heaviest populations are in walnut orchards, dairy …

Methods Of Controlling Starlings And Blackbirds, Adolph Zajanc

Vertebrate Pest Conference Proceedings: 1st (1962)

Most people have accepted the fact that all living things can be beneficial to mankind in some way or other. This is especially true of our wild birds, since they provide enjoyment and wholesome recreation for most of us, regardless of whether we live on farms or in the city. But despite the fact that wild birds are for the most part beneficial, at times individuals or populations of certain species can seriously affect man's interests. When such situations occur, some measures of relief are desirable and usually eagerly sought. This report is not intended to answer all the questions …

Banquet Address: People, Pests And Some Plans, Daniel G. Aldrich Jr.

Vertebrate Pest Conference Proceedings: 1st (1962)

We can probably say that the California way of farming has made California fanners the most over-run hosts to vertebrate pests in the agricultural world. We can certainly say, too, that new pests—and here I don't mean people--are on their way. I'm told that the starlings are just exploring here now. The relatives are coming later. We'll see, and hear, a lot more of them. Our problem is: How do we keep from being such good hosts to our small vertebrate guests? I have been told by experts that right now the vertebrate pest control man is woefully underequipped for …

Control Of Meadow Mice, Kangaroo Rats, Prairie Dogs,, John A. Ludeman

Vertebrate Pest Conference Proceedings: 1st (1962)

Meadow mice, kangaroo rats, prairie dogs and cotton rats are broadly classified as field rodents. The control of their populations have been necessary since man first began to farm and raise livestock within the areas in which these rodents live. The intensity of control has varied with land values and the population fluctuation of the rodents. Rodent control, like other farming practices must be profitable to the land owner, or he cannot afford to undertake a control program. If he is to continue in business his control efforts must be done efficiently and as successfully as possible. To accomplish these …

ALL natural water supplies contain dissolved salts. In wet climates these salts are usually not present in sufficient quantity to cause plant damage.

However, in Western Australia many natural water supplies contain harmful amounts of dissolved salts.

The Magnetic Pole In The Formulation Of Electricity And Magnetism, Robert Katz

Robert Katz Publications

The use of the magnetic pole in the development of the concepts of electricity and magnetism leads unambiguously to a relativistic formulation of the field vectors which is well within the grasp of the sophomore student. The development is wholly consistent with Maxwell's equations and leads to clear and understandable definitions of the field vectors both in vacuum and in the material medium, as well as to the relations defining the transformations of the field vectors.

Effects Of Surface Roughness On The Intensity Distribution Of Light Reflected From Aluminum Surfaces, Harvey N. Wingfield

Master's Theses

Only over the past few years have investigations of the intensity distribution of the light reflected from materials been attempted. Most of these investigations have been done by personnel at the National Bureau of Standards on matt surfaces, and acid etched black glass. It should be noted that separate investigations in the two fields, the methods of analysis of a surface's topography and the intensity distribution of reflected light from different materials have been and still are being performed. However, most correlations which exist between a surface's topography and its optical effects such as reflectance, intensity, absorption, and transmission are …

Growth Study Of Young Gizzard Shad, George Pahl, Gordon Willfahrt

Journal of the Minnesota Academy of Science

This investigation was part of a general study aimed at shedding light upon the role of the gizzard shad (Dorosoma cepedianum) as a forage fish of certain game fish species. Recent changes in the populations of such game fish species as the walleye ( Stizastedion vitreum), northern pike ( Esox lucius) , and largemouth bass (Micropterus salmoides) in the upper Mississippi River suggest that the gizzard shad population might have an important bearing on the present situation. The purpose of this investigation was to study the growth rates of the gizzard shad in the Upper Mississippi River during their first …

A Geologic And Gravity Survey Of The Belle Plaine Area, Minnesota, R. E. Sloan, Z. F. Danes

Journal of the Minnesota Academy of Science

Combined geologic and gravity investigations in the vicinity of Belle Plaine, in the Minnesota River valley, have disclosed a hitherto unknown fault of possible major significance. The fault is inferred on the basis of available evidence to have a left lateral displacement of the order of 100 miles and later vertical movements of about 1,000 feet. The field work was supported by the Minnesota Geological Survey. The writers wish to express their great appreciation to the late Dr. Edward Thiel of the Department of Geophysics and to Dr. J. C. Craddock and Barton Gross of the Department of Geology, University …

The Gascoyne River Catchment Area, W M. Nunn

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

A RECENT Department of Agriculture survey of the Gascoyne River catchment area has indicated that deterioration of plant cover in the area contributes to the severity of floods which regularly damage the town of Carnarvon.

It is hoped that the results of the survey will help efforts to regenerate the catchment area, and reduce the risk of flooding.

On The Structure Of A Class Of Archimedean Lattice-Ordered Algebras, Melvin Henriksen, D. G. Johnson

All HMC Faculty Publications and Research

By a Φ-algebra A, we mean an Archimedean lattice-ordered algebra over the real field R which has an identity element 1 that is a weak order unit. The Φ-algebras constitute the class of the title. It is shown that every ф-algebra is isomorphic to an algebra of continuous functions on a compact space X into the two-point compactification of the real line R, each of which is real-valued on an (open) everywhere dense subset of X. Under more restrictive assumptions on A, ropresentations of this sort have long been known. An (incomplete) history of them …

Lattice-Ordered Rings And Function Rings, Melvin Henriksen, John R. Isbell

All HMC Faculty Publications and Research

This paper treats the structure of those lattice-ordered rings which are subdirect sums of totally ordered rings -- the f-rings of Birkhoff and Pierce [4]. Broadly, it splits into two parts, concerned respectively with identical equations and with ideal structure; but there is an important overlap at the beginning.

K₂O/Na₂O Content As A Possible Index To The Chronological Sequence Of Some Precambrian Igneous Rocks Of Missouri, Erwin Joseph Mantei

Masters Theses

"Flame photometric analyses for K₂O and Na₂O were run on 31 samples of the Precambrian igneous rocks of Missouri. Samples were collected from the field, physically prepared and dissolved by a standard method and a modified standard method of rapid silicate analyses. The K₂O, Na₂O values obtained are averages between two methods of analyses. The modified method reduces by 80% the time required to chemically digest a rock sample. The results for both methods are not significantly different. Curtin and Company Advanced Flame Photometer was used.

Results have been plotted on graphs and a chronological sequence for the named Precambrian …
