The Distribution And Flower Preferences Of The Theclinae Of Texas (Lepidoptera, Rhopalocera, Lycaenidae), H. A. Freeman

Field and Laboratory

In 1944 I began work on the hairstreaks of North America. Since that year, nine new records for the United States, and one new species, were found in the vicinity of Pharr, Hidalgo County, Texas. While collecting over the State, I have found thirty-three species, five subspecies, and two forms, representing five genera of hairstreaks. One new Texas record is reported in this paper, Mitoura siva (Edw.) Most of the information contained here was obtained at first hand; but the fine collection of Stallings and Turner, at Caldwell, Kansas, was checked for Texas specimens.

Field and Laboratory

Four males of the species herein described as new, were collected by Dr. Richard E. Maxwell in Hardin County. Texas, May 11, 1940. Hardin County is in the Big Thicket area of southeastern Texas, where long and short leaf pines are common. The annual precipitation is c. 50 inches; springs, bogs and ponds are frequent; and the humidity is high.

Variations In The Vertebrae And Pelvis Of Necturus, Joseph P. Harris Jr.

Field and Laboratory

In most specimens of Necturus, the nineteenth vertebra serves as the sacrum; the iliac processes of the pelvic girdle articulate with it. In a number of specimens, Vertebra XX or (less frequently) Vertebra XVIII serves as the sacrum. But not always do the two iliac processes join the same vertebra. The iliac process of the left side may join the XVIII, XIX, or XX vertebra. The converse may also occur.

Potato Seed Treatment And Scab Control, L.T. Richardson

Agricultural Experiment Station Plant Pathology Pamphlets (1942-1962)

Treating seed potatoes before planting is recommended for two reasons: to kill the disease organisms on the surface of the tubers causing scab, rhizoctonia, blackleg, and silver scurf; and to prevent the decay of the seed pieces after they are planted. Seed treatment alone will not guarantee a scab-free crop if the soil is already infested with the organism that causes it. Treating cut seed with a suitable disinfectant will improve the stand of plants, particularly when emergence is slow due to weather conditions.

Bulletin No. 338 - Nutrient Deficiencies In Utah Orchards, D. W. Thorne, F. B. Wann

UAES Bulletins

When farm products are sold, some of the essential part of the soil are also marketed. If this process is continued, the soil may be eventually impoverished to the point where it cannot support high crop yields. In addition to direct soil depletion, unbalanced soil management practices may produce soil conditions that prevent or limit the uptake of certain elements by plants even though there may be enough total supply of the elements present to last hundreds or even thousands of years.

Both processes have been going on in many Utah orchards. Sale of fruit has gradually depleted the soil. …

Effects Of Different Intensities Of Grazing On Depth And Quantity Of Roots Of Grasses, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

The writer has been interested in prairies, pastures, and root depth and distribution over a period of many years. He had the privilege of examining these relationships in the Palouse prairie of Washington long ago while numerous representative areas still remained in a virgin condition (5, 6). Extensive studies have been made in the hardlands of Colorado, Kansas, and Nebraska many years before, during, and following the great drought of 1933-40 (7, 8, 1, 11). Vegetation and root habits have been studied in sand hills (7, 8, 4), in bluffs of wind-blown loess (12), and wet soils of lowland. The …

Observations On Histopathological Changes Associated With Starvation In Wisconsin Deer, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Heavy winter losses in deer, apparently resulting directly from an inadequate food supply, have long been known in the United States. The general situation has been well reviewed by Leopold (1943) and by Leopold, Sowls, and Spencer (1947). There is a conservable volume of literature available concerning deer starvation from the management standpoint. The ill-advised attempts at the total destruction or, at best, the severe reduction of natural predator on deer have resulted in the removal of this important population control.

Rodent Populations And Activities On A Moderately Grazed Mixed Prairie Near Hays, Kansas, John L. Paulk

Master's Theses or Doctor of Nursing Practice

The purpose of this investigation was to study rodent populations on a moderately grazed mixed prairie. A working knowledge of the activities of these small mammals, has satisfied to a certain degree the curiosity of the writer. So little work has been done in this plains region that the author felt the need for such an investigation, and hoped to arouse the interest of others along similar lines.

Monolith Method Of Root-Sampling In Studies On Succession And Degeneration, J. E. Weaver, John Voigt

Department of Agronomy and Horticulture: Faculty Publications

A new method has been devised by which a complete sample of an entire root system may be taken from soil surface to maximum depth of penetration. The roots are separated from the soil without injury to them or displacement of individual roots from their natural position. They are examined in the laboratory in relation to the various horizons of the soil profile. Monoliths 12 inches wide, 3 inches thick, and 3-5 feet in depth are taken from the walls of trenches made in selected pure stands of each species. Roots are obtained from the monolith by a system of …

Microorganisms And Soil Structure, T. M. Mccalla

Department of Agronomy and Horticulture: Faculty Publications

SUMMARY

Laboratory tests were made to determine the effectiveness of different compounds and microbial groups in increasing the stability of Peorian loess lumps against the action of falling water drops. The influence of these on percolation tests in the laboratory was also determined.

Many organic substances-dextrose, sucrose, starch, peptone, cullulose, and gum arabic-did not themselves contribute directly to soil-structure stability, though these substances do furnish energy material for soil microorganisms, which can convert them readily into either microbial tissue or decomposition products that increase soil-structure stability. Lignin, proteins, oils, fats, waxes, resin, and paraffin increased the stability of lumps of …

A Comparative Anatomical Study Of The Digestive Systems Of The Desert Jack Rabbit And The Pika, Dale Stanley Rupert

Theses and Dissertations

It is the purpose of this study to make gross and histological comparisons of the various segments of the intestinal tracts of the jack rabbit and the pika. The two animals used for this study were the desert jack rabbit (Lepus Californicus deserticola Mearns), and the pika (Ochotona princepts uinta Hollister). The jack rabbits were found only in the desert valleys and low foothills in the areas studied. These areas are typically open bush or sage brush types of communities. The pikas were restricted to certain high rockslides in this region. These areas are described more completely in the section …
