Vegetational Changes Of The Uinta Basin Since Settlement, Bernard Curtis Dastrup

Theses and Dissertations

A general survey of the vegetational changes of the rangelands of the Uinta Basin was made using historical records, documents, interviews, and recent vegetational surveys. Historical vegetatienal information about the Uinta Basin is very limited, most of it pertaining to the vegetation along the streams and rivers. Escalante, in 1776, mentioned the splendid groves of cottonwoods, the fine pastures, and the abundance of game along the rivers. Ashley in 1825 and Powell in 1870 entered the Basin via the Green River. Ashley crossed the Basin following the Duchesne River and its tributary the Strawberry River. He described the groves of …

Behavioral Isolating Mechanisms In The Family Anatidae, Paul A. Johnsgard

Paul Johnsgard Collection

The ducks, geese, and swans present a host of species-recognition and isolating-mechanism problems that are equaled by few other groups of birds. As a family, the Anatidae have provided the greatest number of interspecific hybridization records of any avian family (see Gray, 1958, and Johnsgard, 1960a) both in captivity and under natural conditions. A surprising number of these hybrids have proved to be fertile, even when obtained between what appear to be well-marked genera. This remarkable capacity for hybridization indicates that isolating mechanisms must be operating effectively if species are to retain their integrity under natural conditions. Since genetic isolation …

Comparative Morphology In Nemic Phylogeny, Armand R. Maggenti

Harold W. Manter Laboratory of Parasitology: Faculty Publications

In 1945 Simpson wrote: "Phylogeny cannot be observed. It is necessarily an inference from observations that bear on it, sometimes rather distantly, and that can usually be interpreted in more than one way." Certainly this applies to a study of nemic phylogeny where our reasoning is based upon degree of resemblance and subject to confusion by convergence and reversal. Many feel that, because fossil records are lacking, it is of little purpose to indulge in speculation on nemic phylogeny. Nemic taxonomy, however, requires such speculation when it is based upon comparative morphology. Our attempts in taxonomy are really an effort …

Two New Gyrodactylus (Trematoda: Monogenea) From Cyprinid Fishes With Synopsis Of Those Found On North American Fishes, Glenn L. Hoffman, Robert E. Putz

United States Fish and Wildlife Service: Publications

Gyrodactylus atratuli from the blacknose dace (Rhinichthys atratulus) and the pearl dace (Semotilus margarita) is compared with known species of Gyrodactylus from North American fishes and described as a new species. Gyrodactylus margaritae from the pearl dace (Semotilus margarita) is compared with known species of Gyrodactylus from North American fishes and described as a new species. The average number of G. atratuli per blacknose dace in the natural habitat is 7.8 (1 to 32) and in the laboratory at the same water temperature after 55 days in captivity, 5.4 (0 to 11). G. atratuli …

Studies On Neogogatea Kentuckiensis (Cable, 1935) N. Comb. (Trematoda: Strigeoidea: Cyathocotylidae), Glenn L. Hoffman, Clarence E. Dunbar

United States Fish and Wildlife Service: Publications

The cercaria of N. kentuckiensis was found in Anaplocamus dilatatus (Nitrocris d.) and Mudalia carinata. The metacercaria was found in all fishes examined from Opequon River, West Virginia, except Cottus bairdi which was also refractory to experimental infection. Two species of Centrarchidae, four of Cyprinidae, three of Salmonidae, Etheostoma flabellare, Platypoecilus maculatus, and Trichogaster trichopterus were experimentally infected. The development of the metacercari and cyst and effect on the fish are described. The histopathology initially consists of hemorrhage and muscle necrosis about the metacercaria, followed by reorganization and formation of a loose connective tissue cyst. The controversial adult names …

Index Catalogue To Russian, Central And Eastern European, And Chinese Literature In Medical Entomology, Volume 1: Diptera, George Anastes

United States Naval Medical Research Unit 3: Publications

Over the past several years a large number of references from the USSR, Eastern Europe, and China have been collected dealing with arthropods of medical importance. These references were coded on keysort cards which made it possible to index as many as fifteen subject areas on one card. The usefulness of this indexing system was evident by the number of medical entomologists who used it in searching for references in their specialty. In response to requests from workers in the United States and other countries who did not have ready access to the index. it was decided to publish these …

Biological Investigations Of The St. Lucie Estuary (Florida) In Connection With Lake Okeechobee Discharges Through The St. Lucie Canal, Gordon Gunter, Gordon E. Hall

Gulf and Caribbean Research

A survey of the turbidity, salinity and sediment effects of St. Lucie Canal discharge into the St. Lucie Estuary was authorized by the Chief of Engineers on May 9, 1955. Expansion of that program to include the work of the present biological investigation was authorized by the Chief of Engineers on June 12, 1956.

The scope and purpose of this biological work was to: (a) review the history of the St. Lucie Canal and analyze the problems concerned with discharges of fresh water into the St. Lucie Estuary: (b) present biological data from a 2-year investigation of estuarine conditions, January …

Southeast South Dakota Experiment Farm Annual Progress Report, 1962, Q.S. Kingsley, F.E. Shubeck, Dwight Hovland, J.J. Bonnemann

Agricultural Experiment Station and Research Farm Annual Reports

This report marks the completion of the second year of research at this farm. Experimental work was continued in the areas of fertility and cultural practices, plant disease control, crop management, and crop variety testing. Investigations were expanded into corn plant populations, potassium deficiency, plant breeding and genetic studies on corn, grasses, legumes, sorghum and soybeans. Livestock research was initiated in the spring of 1962 when 106 feeder pigs were placed in three temporary buildings constructed for this purpose. Results of this trial are summarized in this report. Ninety(90) fall pigs have been started as a continuation of this experiment.

Helminths Of The Shrew-Mole Neürotrichus Gibbsii (Baird) In Oregon, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Helminths of the shrew-mole from Oregon are described. They include a cestode Hymenolepis neurotrichi sp. n., a trematode Microphallus aspalacis sp. n., and the third-stage larva of an undetermined species of Porrocaecum (nematode), probably P. depressum (Zeder, 1800), or P. angusticolle (Molin, 1860). Preserved viscera of ten animals were examined. Three were infected.

Light Horses, M. E. Ensminger

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Light horses stand 14-2 to 17 hands high, weigh 900 to 1,400 pounds, and are used primarily for, riding, driving, or racing, or for utility purposes on the farm. Light horses generally are more rangy and are capable of more action and greater speed than draft horses.

Increasing interest is being shown in light horses. Today, there are 2¼ million horses in this country, of which 1.8 million are light horses. It is further estimated that 433,000 light horses are suburban-owned. About 250,000 horses are registered in a light horse breed registry.

Saddle clubs and 4-H horse clubs are growing …
