Waterfowl Breeding Ground Survey, 1952 In Nebraska, Harvey W. Miller Jan 1952

Waterfowl Breeding Ground Survey, 1952 In Nebraska, Harvey W. Miller

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The Nebraska Breeding Ground Survey has been conducted for the fifth consecutive year. This survey is aimed at providing indicators to the waterfowl population through measuring the seasonal and year b,y year trends in breeding numbers and production success. The survey recognizes the sandhill region as the most important waterfowl-producing area of Nebraska and therefore, studies have been largely concentrated there.

Audio Census Of Some Wisconsin Game Birds, Donald R. Thompson, Charles W. Lemke Jan 1952

Audio Census Of Some Wisconsin Game Birds, Donald R. Thompson, Charles W. Lemke

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

Audio censuses of Wisconsin game birds were commenced in 1948, and now include the bobwhite quail, the pheasant and the ruffed grouse, in the order in which censuses were introduced.

Briefly, audio censuses are based on the characteristic sounds given by the male of the species concerned during the breeding season. An observer strategically located at a station, or stations in the field tallies the number of individuals calling, and/or the number of calls heard during a given time period.

In Wisconsin, only the transect method is used, with the observer following a given route and making listening stops of …

Life History Of The Utah Sculpin Cottus Bairdi Semiscaber (Cope) In Logan River, Utah, William M. Zarbook May 1951

Life History Of The Utah Sculpin Cottus Bairdi Semiscaber (Cope) In Logan River, Utah, William M. Zarbook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The study of the Utah sculpin in Logan River was based on 801 specimens collected during 1949 to March 1951. Numbers of fish examined for various catagories of the study wares length-frequency, 495; aging by vertebrae, 407; length-weight relationship, 601; and food habits, 275.

Fish were collected by use of an electric shocking machine generating 600 watts and 220 volts. Numbers of fish occurred as high as 150 per tenth mile of stream. Preferred habitats occurred in areas of coarse gravel and small rocks.

Vertebrae dissected from the fish were used in age determination. Length-frequency proved to be a general …


Pellet Seeding On Sagebrush Range, Gordon E. Gatherum May 1951

Pellet Seeding On Sagebrush Range, Gordon E. Gatherum

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Seeding deteriorated range lands efficiently and economically has become one of the most promising means of improving the agricultural economy of the western range states. By providing the most rapid means of increasing the quantity and improving the quality of forage for livestock, and aiding in the prevention of soil erosion, artificial seeding contributes directly to the stability of agriculture.

Although many successful methods of artificial revegetation have been developed by experience and through research, there is still a great need for refinement in techniques to insure better overall success and greater economy of operation. Improper methods often result in …

Harvest Of Wild And Stocked Fish From The Logan River Drainage, Louis S. Pechacek May 1950

Harvest Of Wild And Stocked Fish From The Logan River Drainage, Louis S. Pechacek

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Logan River heads in the southeastern corner of Franklin County, Idaho, and runs in a south and westerly direction. It enters the state of Utah through the northern boundary in the northeast corner of Cache County. The main stream is fed by two tributary streams which head in separate directions a few miles apart. The Franklin Basin branch is the main contributing tributary while the Beaver Creek branch is nearly as large.

It's Time To Take Stock

United States Environmental Protection Agency: Publications

Likening colleges and universities to the automobile industry may seem far-fetched, but is it? Each is engaged in fashioning and selling necessary products- one trained men, the other mechanical equipment. Both entered the post-war years with production at low ebb; unable to satisfy pent-up customer demands. Time and high-speed assembly lines have bridged the gap of gas buggy shortage. The impact of selective buying by a discriminating public is now real cause for concern among some of the motor moguls. Rumor has had it that schools teaching wildlife management are overproducing. We decided to gather facts and opinions at the …


Public Health Reports, Clarence M. Tarzwell Feb 1950

Public Health Reports, Clarence M. Tarzwell

United States Environmental Protection Agency: Publications

Preliminary tests with DDT for the control of mosquitoes, forest insects, and agricultural pests demonstrated that it was toxic to a wide variety of animal life. Because there were indications that the new insecticide would be widely used, apprehension was expressed by some groups that its extensive or indiscriminate use would cause extensive harm to wildlife.

The desirability of carefully controlled use was early recognized by those in charge of extensive programs for the control of insects of public health importance. A joint statement of policy for the use of DDT issued early in 1945 (1) by the Army and …

Leaflet No 1003 - The Salt Problem In The Wheat Belt, G. H. Burvill Jan 1950

Leaflet No 1003 - The Salt Problem In The Wheat Belt, G. H. Burvill

Bulletins 1 - 2999

IN the wheat belt of Western Australian bare patches in farm paddocks are often seen. Many are bare, or almost bare, because of too much salt in the soil. The excess of salt prevents the germination of seeds, or kills living plants, because it causes the water supply for germination or growth to be cut off. This salt problem is so serious in places that single farms or groups of farms have been ruined; wheat growing on them has become unprofitable.


Digestion Studies With Sheep And Wild Antelope On A Sagebrush Ration, Paul Harold Kohler Jan 1950

Digestion Studies With Sheep And Wild Antelope On A Sagebrush Ration, Paul Harold Kohler

Electronic Theses and Dissertations

Introduction: Those who are responsible for the management of antelope, range livestock, and the range seek to maintain such a balance that al may thrive and reproduce. This is inevitably a difficult objective since the balance in numbers of antelope and livestock may be changed annually, but range flora changes only in long-time cycles. Therefore, the balance between the wild and domestic species and the range must be adjusted frequently by range and livestock management. The adjustment of the number of domestic animals to fit the carrying capacity of the range may be accomplished by changing management and marketing practices …
