Microorganisms And Soil Structure, T. M. Mccalla, F. A. Haskins
Microorganisms And Soil Structure, T. M. Mccalla, F. A. Haskins
Department of Agronomy and Horticulture: Faculty Publications
SUMMARY
Good stable soil structure is valuable for promoting the growth of plants and micro-organisms by permitting enhanced aeration and water penetration and by decreasing erosion under some conditions.
Micro-organisms influence water percolation through the soil. They may plug up soil pores with byproducts of growth and reduce water percolation. On the other hand, if a soil containing a large amount of microbial products is stirred and allowed to dry, then the percolation may be high.
Micro-organisms are involved in stabilizing soil structure by their products of decomposition and their cellular binding material, such as mycelia. Microorganisms differ greatly in …

Pensternon In Your Garden, Glenn Viehmeyer
Pensternon In Your Garden, Glenn Viehmeyer
Department of Agronomy and Horticulture: Faculty Publications
A new race of hardy perennials is beginning to appear in American gardens. These are the penstemons, a genus of plants closely related to the familiar snapdragon, which may become important ornamentals as they become better known to gardeners. The purpose of this bulletin is to show the possibility of the genus as an ornamental and to suggest species and species hybrids of possible value to Great Plains gardeners; to provide information about propagation and culture; and to encourage gardeners to engage in penstemon breeding as an avocation.
Evolutionary Relationships Among The North American Mallards, Paul A. Johnsgard
Evolutionary Relationships Among The North American Mallards, Paul A. Johnsgard
Papers in Ornithology
A comparative morphological, behavioral, and electrophoretic study was undertaken on six populations of North American mallards that are currently considered by the A.O.U. Check-list to comprise four species and two additional subspecies. These include Anas p. platyrhynchos, A. d. diaxi, A. d. novimexicana, A. f. fulvigula, A. f. maculosa, and A. rubripes. These forms are essentially allopatric in their breeding distributions, with the major exception of A. p. platyrhynchos and A. rubripes, which overlap throughout a several-hundred-mile zone in east-central United States.
Geographic ranges and population sizes are estimated, and evidence is presented to indicate that the …
Notes On The Collared Pika, Ochotona Collaris (Nelson), In Alaska, Robert L. Rausch
Notes On The Collared Pika, Ochotona Collaris (Nelson), In Alaska, Robert L. Rausch
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Maps showing the geographic range of the collared pika, Ochotona collaris (Nelson), have been published recently by Hall (1951) and by Hall and Kelson (1959). According to these, this mammal occurs in the mountains between the Tanana and Yukon Rivers, and in the Alaska Range as far west as Mt. McKinley. A specimen from the summit of the Chugach Mountains (Baker, 1951) was not included on the aforementioned maps. Osgood (1904) referred to two specimens collected by C. L. McKay in the Chogmit Mountains, east of Lake Clark at the base of the Alaska Peninsula, and also mentioned a sight …

Mycorrhizae Of Ponderosa Pine In Nebraska Grassland Soils, R. W. Goss
Mycorrhizae Of Ponderosa Pine In Nebraska Grassland Soils, R. W. Goss
Nebraska Agricultural Experiment Station: Historical Research Bulletins
While the genus Pinus has been the subject of extensive mycorrhizal studies there are only a few scattered references to western yellow pine, P. ponderosa, and no detailed descriptive literature on the mycorrhizae of this species. P. ponderosa is indigenous to Nebraska and the one species most extensively grown in local nurseries for windbreaks and farm plantings. Similarly, there is little information on mycorrhizae in the Great Plains between the forested regions of the Mississippi River states and the Rocky Mountains. Because this predominantly grassland area is sparse in natural tree growth the individual tree as an ornamental or …

Genetic Control Of Coumarin Biosynthesis And Β-Glucosidase Activity In Melilotus Alba, G. W. Schaeffer, Francis A. Haskins, H. J. Gorz
Department of Agronomy and Horticulture: Faculty Publications
Two pairs of alleles, Cu/cu and g/5, are known to influence coumarin biosynthesis in Melilotus alba Desr. (Goplen e t al., 1957 ; Haskins and Gorz, 1957). Young leaves from CuCuBB plants characteristically contain substant i a l akounta of both free and bound co-in, CuCubb leaves are high in "coumarin" but virtually a l l the substance is in the bound form, and cucuBB and cucubb leaves are low in both forms. Lt has been suggested that the gene is involved in the formation of bound coumarin from coumarin precursors and that the gene is concerned with the conversion …

A Quantitative Study Of Sexual Behavior Of Mallards And Black Ducks, Paul A. Johnsgard
A Quantitative Study Of Sexual Behavior Of Mallards And Black Ducks, Paul A. Johnsgard
Papers in Ornithology
In recent years an increased interest in the use of behavioral characteristics in evolutionary studies has developed, and this is particularly true in the case of waterfowl. The classical studies of Heinroth (1911), who was one of the first to apply knowledge of waterfowl behavior to systematics, have been elaborated on by Lorenz (1941; 1951-1953) in his important contribution toward the understanding of relationships in the Anatinae. These, and other, studies have stressed the qualitative behavioral differences occurring among different species as providing possible isolating mechanisms through their presumed function of conveying species-specific recognition signals. To the present, no extensive …
The Nebraska Sandhill Lakes: Their Characteristics And Fisheries Management Problems, D. B. Mccarraher
The Nebraska Sandhill Lakes: Their Characteristics And Fisheries Management Problems, D. B. Mccarraher
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
A brief look at the map of Nebraska will readily point out the obvious fact that the sandhills comprise a considerable portion of the land area of the state. To be more precise, an area encompassing around 20,000 square miles or about one quarter of the total state area. This is indeed a vast prairie region long noted for its fine cattle and native hay crops. It is a region of vegetative dune sandhills, sandy basins and valleys, exposed ground water, spring seep lakes and marshes. Since much is already known concerning the land portion of the sandhills it is …

Coordination Of Mosquito Control And Wildlife Management Some Effects Of Mosquito Larviciding And The New Pesticides On Fishes, Clarence M. Tarzwell
United States Public Health Resources
It is apparent to one who has been brought up on a farm and who has worked in the fields of mosquito control, fisheries management, and water pollution abatement, that there are some conflicts of interest and methods used in these fields. There are, however, many common interests and areas in which the aims and objectives coincide. All too often in the past. there has been a failure to explore and stress common interests and a tendency to emphasize conflicting interests. Our present age of specialization in, training and interest is in part responsible for this situation. In order to …
Hybridization In The Anatide And Its Taxonomic Implications, Paul A. Johnsgard
Hybridization In The Anatide And Its Taxonomic Implications, Paul A. Johnsgard
Papers in Ornithology
Without doubt, waterfowl of the family Anatidae have provided the greatest number and variety of bird hybrids originating from both natural and captive conditions. The recent compilation by Gray (1958) has listed approximately 400 interspecies hybrid combinations in this group, which are far more than have occurred in any other single bird family. Such a remarkable propensity for hybridization in this group provides a great many possibilities for studying the genetics of speciation and the genetics of plumage and behavior, and it also provides a valuable tool for judging species relationships. It may generally be said that the more closely …
Application Of Beutel’S Experimental Jurisprudence To Japanese Sociology Of Law, Shin Oikawa
Application Of Beutel’S Experimental Jurisprudence To Japanese Sociology Of Law, Shin Oikawa
Nebraska Law Review
This translation of a Japanese study of an American scholar’s work in Experimental Jurisprudence is perhaps best introduced in the words of the Japan Reading Newspaper review of February 29, 1960: “Shin Oikawa . . . tries to absorb Beutel’s study which is, among the recent fruits of American Jurisprudence, inclined toward legal realism, and he does so from the standpoint of a specialist in sociology of law in Japan. Considering the present condition of Japanese Jurisprudence, it is important to realize the necessity that such an article be read by many people. Conclusively, his article has important significance.” Professor …

Pike Hybrids (Esox Lucius X E. Vermiculatus) In A Sandhill Lake, Nebraska, D. B. Mccarraher
Pike Hybrids (Esox Lucius X E. Vermiculatus) In A Sandhill Lake, Nebraska, D. B. Mccarraher
Nebraska Game and Parks Commission: Staff Research Publications
In the sandhill region of Nebraska both northern pike, Esox lucius, and grass pickerel, Esox vermiculatus, are abundant in several shallow natural lakes. Both species are known to utilize the same vegetative habitat for spawning during March and April. The pike is an important game species but the smaller pickerel is of little value to fishermen although in winter is at times taken by angling through the ice.

Annual Report- Game Division, Lloyd P. Vance, Shirley Lindholm
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
Two classes of game farm permits were made available by the 1957 legislature to persons keeping protected species of wildlife in captivity. A pet or fancier permit authorizes the possession of fifty or less game birds or game animals where no commercial use is made of such wildlife. A commercial permit authorizes the possession of game birds and game and fur-bearing animals of regardless of number, where trade, sale, barter, or any commercial use is involved. During 1960, 195 pet permits and 92 commercial permits were issued for a total of 287 permits. In 1959 a total of 432 permits …

Comparison Of Vegetation Of Kansas-Nebraska Drift-Loess Hills And Loess Plains, J. E. Weaver
Comparison Of Vegetation Of Kansas-Nebraska Drift-Loess Hills And Loess Plains, J. E. Weaver
Department of Agronomy and Horticulture: Faculty Publications
The western edge of True Prairie gives way very gradually on the Loess Plains south of the Platte River to Mixed Prairie of the Great Plains. North of the Platte a similar transition occurs in the valleys and on the slopes of the Loess Hills. But in northern Kansas the True Prairie of the Kansas-Nebraska Drift-Loess Hills is definitely separated by the Flint Hills Region from its western edge on the Kansas-Nebraska Loess Plains. In this study the vegetation, soils, and other environmental factors of the two areas are described and compared.

Studies On The Helminth Fauna Of Alaska. Xxxvi. Parasites Of The Wolverine, Gulo Gulo L., With Observations On The Biology Of Taenia Twitchelli Schwartz, 1924, Robert L. Rausch
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Natural biotic relationships already had been severely disrupted in the United States by the time significant interest had developed in faunistic helminthology. Some mammalian species, particularly the larger carnivores, had been extirpated or were represented only by scattered individuals in the few remaining wilderness areas. Thus, it is not remarkable that the helminths of such species as the wolverine, Gulo gulo Linnaeus, have been little studied. Fortunately, however, much of arctic and subarctic North America has endured in its primitive state, and here it is still possible to undertake basic biological studies under undisturbed conditions.
