Factors Affecting Nesting Success Of The Canvasback In The Aspen Parklands, Jerome H. Stoudt

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The Minnedosa study area is located in the southwestern portion of Manitoba just south of the town of Minnedosa. It is 90 square miles in size and roughly square in shape. The Aspen Parkland, in which the study area is located, is characterized by gently rolling terrain and black soils. Mixed farming is the rule with emphasis on small grain production consisting of wheat, barley, and oats. Roughly 50 percent of the water areas in the parkland are ringed with aspen, Populus tremuloides, and large blocks of aspen are interspersed throughout the area. The Minnedosa area differs because of …

Report On A Visit To Israel August-September 1964, D J. Carder Jan 1965

Report On A Visit To Israel August-September 1964, D J. Carder

Soil conservation survey collection

The main features in which farming methods and the environment in Israel differ from those in Western Australia, as they appeared to me, are:- the dominant sedimentary and limestone geology with its accompanying soil and moisture conditions population pressure which puts a premium on agricultural productivity and research the widespread use of sprinkler irrigation. These factors interact in various ways so that, although many problems are similar in the two countries (both have many pioneering problems remaining) the approaches to them vary considerably.

WITH the ever-increasing spread of salt in certain poorly-drained soils in Western Australia, any plant which tends to restrict salt encroachment is of considerable economic importance.

In the genus Eucalyptus there are a few trees which will withstand a certain degree of soil salinity.


The Archeology Of The Lime Creek Site In Southwestern Nebraska, E. Mott Davis Jul 1962

The Archeology Of The Lime Creek Site In Southwestern Nebraska, E. Mott Davis

University of Nebraska State Museum: Staff and Affiliates, Publications

The Lime Creek site is a stratified Early Lithic (Paleo-Indian) camp site buried in the Terrace-2A alluvial fill of a valley in the dissected loess plains. Geological correlations indicate an early Valders (Wisconsin- IV) date. A radiocarbon date (No. C-471) of 9524 B.P. from just below Lime Creek I, the lowest occupation zone, must be taken only as a minimal possible age for the site. The animal bones in Lime Creek I are primarily of pronghorn and beaver, whereas those in Lime Creek III, the highest occupation zone, are exclusively of bison. The change in hunting patterns seems due to …

National Oceanographic and Atmospheric Administration: Technical Reports and Related Materials

Some general characteristics of thirteen tornadoes that occurred on the afternoon of June 27, 1955 in Scottsbluff County, Nebraska, are related. Two of these caused widespread attention due to their size and their proximity to the cities of Scottsbluff and Mitchell, Nebraska. These two were photographed extensively by residents near their paths. The experience of two men directly beneath one of the two large tornadoes is related.


Field Techniques For Sexing And Aging Game Animals, Donald R. Thompson Jan 1958

Field Techniques For Sexing And Aging Game Animals, Donald R. Thompson

Nebraska Game and Parks Commission: Publications

The purpose of this booklet is to provide a ready field reference for identification, sexing and aging of common game species. It has purposely been kept in simplified form, presenting only those techniques which can commonly be applied in the field and avoiding those which would require special equipment and skills. Untrained personnel should be given demonstrations of the techniques, and thereafter this reference should serve as a reminder. It is not expected that the reference could successfully be used without such demonstration. Certain of the techniques such as cloaca! examination of waterfowl may require considerable practice by the individual. …

These monogeneans were collected by Harold W. Manter in Wellington, New Zealand, in 1951 from the gills of Seriolella brama (Günther), the warehou (Family Nomeidae). A study of the three specimens collected indicates they belong to a new genus of the family Diclidophoridae, subfamily Cyclocotylinae.


Effect Of Time Of Cutting On Yield And Botanical Composition Of Prairie Hay In Southeastern Nebraska, Elverne C. Conard, Vincent H. Arthaud Nov 1957

Effect Of Time Of Cutting On Yield And Botanical Composition Of Prairie Hay In Southeastern Nebraska, Elverne C. Conard, Vincent H. Arthaud

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Approximately three and one-third million acres of native prairie are harvested annually in Nebraska for hay. In the four-year period 1948-1951, the State ranked first in wild hay production with an average yield of more than two and one-quarter million tons per year. This crop is an important natural resource in Nebraska's livestock industry. Studies were initiated in 1945 to determine the effects of time of cutting on the yield and feeding value of prairie hay in southeastern Nebraska. The studies were continued through the summer of 1952 to determine the effects of different cutting treatments on the vigor and …


Nebraska Deer, William Bailey Jr., George Schildman, Phillip Agee, C. G. Pritchard Jan 1957

Nebraska Deer, William Bailey Jr., George Schildman, Phillip Agee, C. G. Pritchard

Nebraska Game and Parks Commission: Publications

IN COMMON with the experience of most states, Nebraska's deer herds were reduced to a very low level by excessive harvests in our early history. Most American big-game animals were overharvested in the early history of this nation because of commercialization. Buffalo were killed for their hides, deer for their meat. This slaughter continued as long as the hunter (or poacher) could sell his take at a profit. Modem game management and public opinion reversed this trend. Deer are on the way back all over America, and in some states the protection-complex was so strong that deer were restored to …

Two New Species Of Prosorhynchinae (Trematoda: Gasterostomata) From The Fiji Islands, Harold W. Manter Jan 1953

Two New Species Of Prosorhynchinae (Trematoda: Gasterostomata) From The Fiji Islands, Harold W. Manter

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The following trematodes are part of a collection made by the author at Suva, Fiji in 1951.

1. Prosorhynchus squamatus Odhner, 1905 is believed to be distinct from P. crucibulus and most other species in the genus on the basis of its oval-shaped rhynchus. It thus remains, as originally, the type species of the genus.

2. Prosorhynchus thapari n. sp. is described from Plectropoma maculatum (Bloch) from Suva, Fiji. The "P. facilis (Ozaki, 1924)" of Nagaty (1937) is considered to be a synonym.

3. Neidhartia polydactyli n. sp. is described from Polydactylus plebius (Bonnaterre) from Suva, Fiji.

Microorganisms And Soil Structure, T. M. Mccalla Mar 1950

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 …
