Observations On A Cyclic Decline Of Lemmings (Lemmus) On The Arctic Coast Of Alaska During The Spring Of 1949, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The importance to the biotic community of various species of lemmings in arctic and subarctic regions has long been recognized, but there is little known about the ecology of these mammals. of the two species that occur on the Arctic Slope of Alaska, namely, the collared lemming, Dicrostonyx groenlandicus rubricatus (Richardson), and the brown lemming, Lemmus trimucronatus alascensis Merriam, during the spring of 1949 the writer had the good fortune to observe a cyclic decline in the population of the brown lemming on the Arctic Coast of Alaska. Observations were made during the peak density preceding this decline and were …

Special Text, St 55-30-1, Transportation Intelligence, November 1950, Robert Bolin , Depositor

United States Department of Defense Military Intelligence

This is a textbook used at the Army Transportation School run by the Transportation Corps. In the 1950s, military schools related to one of the Army Technical Services were run by that service.

The modern US Army vision of the technical intelligence developed during World War II. Shortly before World War II, Army Technical Services had been instructed to set up intelligence sections in the offices of their chiefs. The technical services were bureaus which supplied weapons, equipment, and services to the Army, managed the careers of officers in a particular branch, trained specialists, and organized and trained special purpose …

Airplanes were first used in agriculture shortly after the close of World War I. They proved valuable for locating mosquito breeding areas, for forest fire patrol work, as an aid in locating outlaw cotton fields in the campaign against pink bollworm, and for surveying damage caused in large forested areas by the spruce budworm.

A Preliminary Note On Trichinosis Investigations In Alaska, P. J. Brandly, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Trichinosis in the arctic regions of the world has received considerable attention during recent years, particularly since the work of Roth (1948) in Greenland. In Connell's (1949) review of arctic trichinosis some Alaskan and Canadian records were included but, until now, little has been known of the status of the disease in Alaska. Information available at the present time indicates that the incidence of trichinosis is high in circumpolar carnivores and that marine mammals have a definite place in its epizootiology. Present knowledge cannot explain the survival of trichinosis in marine mammal populations, but it is evident that they may …

Bear River: A National Wildlife Refuge, Vanez T. Wilson, Rachel Carson

United States Fish and Wildlife Service: Publications

In the autumn of 1824 a buffalo-hide canoe drifted down the Bear River to its mouth in the Great Salt Lake of Utah. Within sight of that vast inland sea, Jim Bridger must have paused in amazement. Everywhere he looked-in the sky, on the open water, over the marshy borders of the lake-there were birds. It is said that the famous explorer of the western wilderness brought back reports that he had that day seen "millions of ducks and geese."

The Bear River marshes were soon to know years when their waterfowl were numbered, not by millions, but by thousands; …

Notes On Microtine Rodents From The Brooks Range, Arctic Alaska, Robert L. Rausch, David H. Johnson

Harold W. Manter Laboratory of Parasitology: Faculty Publications

In connection with parasitological studies carried on during 1949 for the U.S. Public Health Service, the writer collected a considerable number of mammals from the northern edge of the "Endicott" section of the Brooks Range, in Arctic Alaska. The mammalian fauna of this region is poorly known, since apparently no previous collecting has been done here. About 200 microtine rodents were collected, mostly near Tolugak Lake (latitude 68° 24' N, longitude 151° 26' W), near the head of the Anaktuvuk River Valley. A few specimens were also taken at Umiat, on the Colville River, about 80 miles north of Tolugak …

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 …

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 …

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 …
