Genetic Studies Of Induced Mutants In Melilotus Alba. Iv. Inheritance And Complementation Of Six Additional Chlorophyll-Deficient Mutants, R. R. Ronnenkamp, Herman J. Gorz, Francis A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

Six ethyl methanesulfonate-induced chlorophyll-deficient mutants of Melilotus alba Desr. were studied. Each of the mutants behaved as a monogenic recessive. Complementation analysis revealed that the genes from five of the mutants were nonallelic to each other and to the previously reported mutants ch₄, ch₅, ch₆, and ch₇. Proposed symbols for the five genes are ch₈, ch₉, ch₁₀, ch₁₁, and ch₁₂. No linkage was detected between ch₅ and ch₇, ch₇, and M_f, (multifoliolate leaf), ch_{8 …}

The Changing Congressional Climate, Clayton K. Yeutter

Clayton K. Yeutter, United States Secretary of Agriculture: Papers

The current legislative climate for American agriculture is illustrated by the House Agriculture Committee in the new Congress. The committee in the last session had 37 members and was chaired by Rep. Poage of Texas. The House Agriculture Committee today has 43 members, and is chaired by Rep. Foley of the State of Washington.

The committee was enlarged this session to make room for all of the new Congressmen who wanted to serve on it. Only a few years ago, new Congressmen had to be dragooned onto the Agriculture Committee.

Quick Economic Action Needed To Help Agriculture, Yeutter Says:, Clayton K. Yeutter

Clayton K. Yeutter, United States Secretary of Agriculture: Papers

"American agriculture needs a healthy non-farm economy to prosper fully. Right now, that means taking some strong economic medicine, which President Ford has prescribed," said Clayton K. Yeutter, Assistant Secretary of Agriculture and Nebraska farmer-rancher in Omaha today. Speaking to the Omaha Chamber of Commerce Agribusiness Club, Mr. Yeutter said that the economies of the United States and most of the world have been thrown out of kilter by the combination of the oil crisis and business cycle downturns.

Looking Forward, Clayton K. Yeutter

Clayton K. Yeutter, United States Secretary of Agriculture: Papers

A couple of weeks ago, on my Far Eastern tour, I visited a farm in Taiwan. The contrast with Montana could not have been more striking.

This was a good-sized farm by Taiwanese standards, about 10 acres. It is farmed by a father and his six sons, and provides most of the support for the 40 people in their families. The agriculture is highly intensive. They alternate rice and vegetables on their land, getting at least two crops of each per year. They were also raising hogs--completely confined from birth to slaughter because land is so precious. There were no …

Scimitar-Toothed Cats, Machairodus And Nimravides, From The Pliocene Of Kansas And Nebraska, Larry D. Martin, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum (1924–2023)

"Machairodus catocopis Cope" is shown to be a pseudaelurin cat belonging to the genus Nimravides Kitts. Nimravides thinobates (Macdonald) is a possible synonym of N. catocopis (Cope). Nimravides is compared with the Eurasian Machairodus-like cat, Dinofelis. Machairodus (Heterofelis) coloradensis is reported from the Kimball Formation, upper Pliocene (Kimballian) of Cheyenne County, Nebraska, and from the upper part of the Ash Hollow Formation, Pliocene (Hemphillian) of Sherman County, Nebraska. The Kimballian form is described as a new subspecies, Machairodus coloradensis tanneri.

The genus Machairodus has long been associated with the Hemphillian of North America and the …

A New Kimballian Peccary From Nebraska, C. Bertrand Schultz, Larry D. Martin

Bulletin of the University of Nebraska State Museum (1924–2023)

A new species of Pliocene peccary, Prosthennops (Macrogens) graffhami; is described from the Kimball Formation, Ogallala Group, Frontier County, Nebraska. This new species is the latest in geologic age and most advanced in the genus.

The remains of fossil vertebrates are generally rare in the upper part of the Ogallala group, and some have maintained that Hemphillian faunas such as Coffee Ranch and Smith County, Kansas, represent the latest Ogallala faunas. Later faunas than are typically considered as Hemphillian, containing more advanced forms, occur in the Kimball Formation and deposits of equivalent age. Known faunas which may …

Bears (Ursidae) From The Late Cenozoic Of Nebraska, C. Bertrand Schultz, Larry D. Martin

Soybeans -- What To Look For In 1975, Clayton K. Yeutter

Clayton K. Yeutter, United States Secretary of Agriculture: Papers

I have just returned from a tour of our major farm product customers in the Far East -- Japan, Korea, Taiwan and the Philippines. The most impressive thing I found there was the forward-looking spirit of these nations, and their driving determination to continue their economic growth in spite of the world's current energy and inflation problems.

All of these nations are vitally interested in American farm products, with soybeans high on their priority lists. All of them are looking past the current recession atmosphere, and planning for the future. All of them have more protein for their diets as …

Food Trade And Aid, Clayton K. Yeutter

Clayton K. Yeutter, United States Secretary of Agriculture: Papers

The key question on food policy in the world today is how we can get maximum effective output from the world's agriculture in the years ahead. ·World food production will likely need to double in the next 25 years if we are going to meet the needs of the world's rapidly growing population and to provide the higher standard of eating that so many of the world's peoples desire.

We cannot attain that level of efficient food production without a far more efficient and effective world agriculture than we have today.

The Prediction Of Lake Huron Lake-Effect Snowfall Systems, Kenneth F. Dewey

School of Natural Resources: Faculty Publications

Data was collected during the 1971-72 snowfall season for the Lake Huron basin. The bulk aerodynamic approach, as formulated by Priestly, was utilized to estimate the daily average flux of heat and moisture over the lake. It was hypothesized that discriminant analysis could be employed to determine the threshold value (discriminant index) of the energy flux which is necessary for the occurrence of the lake-effect snowfall system. To determine the validity of this threshold value, the discriminant index was applied to a series of historical data. The results of this analysis indicated that the discriminant index could be utilized to …

Physics Teaching and the Development of Reasoning: Workshop Materials

Most physics teachers think about their courses in terms of topics covered, concepts explained, and principles applied. Our effort in this workshop has been to call your attention to another impartant dimension of physics teaching: your students' patterns of reasoning. By this time, you have probably concluded that most physics courses are addressed primarily to students who can use formal reasoning patterns with ease, and we would agree with that. Yet there are also the students who use formal reasoning patterns only with difficulty and in limited areas. To help you analyze course content and present it in a way …

A Revision Of The Nearctic Species Of The Genus Phronia (Diptera: Mycetophilidae), Raymond Gagne

USDA Systematic Entomology Laboratory

Phronia contains 86 species of small, brown or black mycetophilids. Adults of these fungus gnats are most often caught flying above the forest floor, especially along damp ravines. The fungivorous larvae have been found grazing on slime molds growing on the surface of decaying logs. Most species occur in the Holarctic region, but 1 described and several undescribed species are known from the Ethiopian region. In North America, there are 49 species, 33 of which are known also from Europe.

Age Determination Of Female Redhead Ducks, Charles W. Dane, Douglas H. Johnson

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

Eighty-seven fall-collected wings from female redhead ducks (Aythya americana) were as- signed to the adult or juvenile group based on "tertial" and "tertial covert" shape and wear. To obtain spring age-related characters from these fall-collected groupings, we considered parameters of flight feathers retained until after the first breeding season. Parameters measured included: markings on and width of greater secondary coverts, and length, weight, and diameter of primary feathers. The best age categorization was obtained with discriminant analysis based on a combination of the most accurately measured parameters. This analysis, applied to 81 wings with complete measurements, resulted in …

Herpesvirus Disease Of Salmonids, Ken Wolf, Tokuo Sano, Takahisa Kimura

United States Fish and Wildlife Service: Publications

A newly recognized virus, lethal for fry and fingerlings, has been isolated from brood stock rainbow trout (Salmo gairdneri) at the Winthrop National Fish Hatchery, Washington. A similar if not identical virus has been found in natural epizootics occurring annually since 1970 among fry of landlocked sockeye salmon (Oncorhynchus nerka) on Honshu Island, Japan. More recently, this agent was isolated from moribund and dead adult O. nerka on Hokkaido Island; Japan, but it remains to be determined whether or not the virus causes death in adult salmonids. The purpose of this leaflet is to bring the …
