Bird Populations Of The Wasatch Foothills, Delwyn G. Berett

Theses and Dissertations

One of the more interesting and unique of the natural habitats in the state of Utah is its chaparral zone, extending along the western foothills of the Wasatch Range. The purpose of this study has been to make an analysis of the bird population of this region in order to determine the comparative abundance of the species, their seasonal distribution within the area, and their ecological preferences.

Genetic Variation In Bluebunch Wheatgrass, Max P. Dunford

Theses and Dissertations

Agropyron spicatum (Pursh) Scribn, and Smith, an important forage grass distributed primarily throughout western United States and northward into Canada, exhibits considerable ecological, cytological, and genetic variation. Twenty-five populations of 100 plants each were scored to obtain data on morphological and ecological variation. Statistical analysis of the data from fourteen of the populations showed that correlations between awn divergence and length, rhizomes with number of culms, adn diameter with number of culms were inconsistent or not significant. However, the correltion between rhizomes and diameter was significant in all populations.

The Comparative Mineral Requirements Of Pioneer And Climax Range Grasses, Paul L. Steele

Theses and Dissertations

A study was made to determine the effects of variable levels of nitrogen, phosphorus, and potassium upon several species of pioneer and climax range grasses, and to determine if these grasses differ in their ability to grow when supplied with low levels of these nutrients. Five grasses were used. The climax grasses were Agropyron spicatum and Agropryon smithii, and the pioneer grasses were Aristida longiseta, Sporobous cryptandrus, and Oryzopsis hymenoides.

Agricultural Drought In South Dakota: How Many Droughty Days Per Season?, Ray F. Pengra

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

The purpose of this study was to determine the likelihood of different numbers of drought days per season in ten selected areas of South Dakota using weather data accumulated by the Weather Bureau. Information on the likelihood of drought within the Great Plains is of primary importance for any type of farming. For the prospective irrigation area in central South Dakota such information is essential to determine the extent of irrigation needed and the type of irrigation that will be best adapted to the needs of the area.

Economic And Legal Aspects Of Vertical Integration, Dale C. Dale

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

Vertical integration, on the other hand, is the grouping of two or more complementary firms on different levels of the production-marketing process. For example, a processor and a farmer may unite or a supplier, farmer, processor and wholesaler may combine under centralized management. The key idea is the extent of control that can be exercised by the central decision maker or "integrator," It is important to understand that vertical integration is concerned only with single enterprises or single commodities at the present time. A multi-enterprise farmer may integrate only part of his farming operation. A farmer who deals in wheat, …

Hypoxylon Infection Not Greatly Influenced By Sex Of Aspen Trees, G.W. Anderson

Aspen Bibliography

The results of a survey taken in northern Minnesota indicate that the occurrence of Hypoxylon canker on aspen has little or no correlation with the sex of the tree. This survey was made during the flowering seasons of 1957 and 1958.

The External Morphology Of Pseudopanurgus Aethiops (Cresson), Glenn A. Hackwell

Theses and Dissertations

In comparing the head of Pseudopanurgus with Anthophora and Apis, the general outline appears rather similar, the most significant variation being found on the posterior surface. Extending ventrally from the postoccipital suture to the dorsal wall of the proboscidial fossa is a suture known as the fused hypostomal suture. The hypostomal area is rather small and makes up only a small portion of the dorsal and lateral walls of the proboscidial fossa, the remainder being formed by the postgena. If this is correct, the hypostomal carinae (a term with which the author does not agree) are actually located on the …

The Occurrence And Distribution Of Birds On Middleton Island, Alaska, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A survey of the birds of Middleton Island was made in June 1956. Forty-five species of birds were recorded. Of these, at least 16 species were breeding, four other species were possibly breeding, and 2.5 species were regarded as transients. The distribution of the breeding birds was correlated with six major ecological formations. Five of the latter were based on vegetational characteristics, while the rocky cliffs comprised the sixth.

The avian fauna of Middleton Island consists mainly of species found in the Prince William Sound region, to the north. An important exception was the Lapland Longspur, which previously has not …

Classification Of Root Systems Of Forbs Of Grassland And A Consideration Of Their Significance, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Plants other than grasses constitute an important part of the native grasslands of North America. Most of these are forbs, a few are shrubs and half-shrubs. Probably 85 to 90 percent of the forbs are perennial and most are as deeply rooted and many far more deeply rooted than the grasses. Their number varies considerably from place to place. In the prairie of the central part of the North American Lowland and on the hard lands and sandy soils of the Great Plains they compose, perhaps, between 5 and 15 percent of the vegetation. They are least abundant in the …

Studies On The Microcrustacea Of Three Montane Lakes In Glacier National Park, Montana, Robert O. Megard

Biology ETDs

Grinnell Lake, Lake Josephine, and Swiftcurrent Lake, at an elevation of approximately 5,000 feet in northwestern Montana, are comparable with lakes in the montane zone defined by Pennak for lakes at elevations between 8,200 feet and 10,500 feet in the Rocky Mountains of northern Colorado. Five species of Copepoda, six Cladocera, and four Ostracoda were collected in the lakes studied. The population of microcrustacea in these lakes was most dense in or slightly above the masses of rooted aquatic vegetation growing to a height of six to 10 inches above the bottom wherever the water was between three feet and …
