The Biosystematic Problem, Robert W. Long Jr.

Field and Laboratory

The new approach to taxonomy, variously called "The New Systematics", "Experimental Taxonomy", or “Biosystematics", is now a recognized branch of biology. The growth of this new approach during the past three decades has not only renewed interest in taxonomy among taxonomists, but has also demonstrated to the other disciplines of biological science the implications of taxonomic research to their work. The purpose of the present paper is to review briefly the methods and purposes of the biosystematists in the hope that study of this kind may be encouraged in the Southwest. In this region, problems of species that lend themselves …

Plankton Studies Of The Tomales Bay, California, Andrew William Mcclain

University of the Pacific Theses and Dissertations

These studies on the plankton of Tomales Bay were designed to determine the effects of such physical factors as tides, temperatures, salinities and sunshine on the quantities of various types of organisms, and to obtain a more comprehensive picture of estuarine life at the Pacific Marine Station. The studies were begun in the summer of 1948 and continued through the summer of 1953.

Although various studies have been conducted on different aspects of marine plankton, the only general treatments of the subject of which the writer is aware are those of Johnstone (1924), Ricketts and Calvin (1951), Sproaton (1949) and …

North American Prairie, J. E. Weaver

Papers of John E. Weaver (1884–1956)

TO MOST AMERICANS, the word "Prairie" suggests either a romantic element in pioneer fiction or a vast expanse of level land which must be crossed in going from one coast to another. But to the botanist, the American Prairie is a wonderfully complex society of living organisms.

This book tells the story of that society-the variety of its inhabitants; the constitution of its several communities; the internal struggles for domination of the society; and the battles of the Prairie as a whole against its two most vicious enemies, drought and overgrazing. Most striking, perhaps, is the story of that portion …

The Growth Of Pathogenic Bacteria In Soluble Oil Emulsions, Hilliard Pivnik, W.E. Engelhard, T.L. Thompson

Papers in Microbiology

Mineral oils, when emulsified with materials such as soaps of petroleum sulfonates, fatty acids, abietic acid or resin, are referred to as soluble oils. These oils, mixed with water, form stable emulsions which are universally employed as coolants and lubricants for drilling, cutting, and grinding of metals. In addition to the emulsifying agent, soluble oils may also contain fatty oils, disinfectants and emulsion stabilizers.
The oils supplied by the manufacturer are sterile, but when mixed with water in the machine shop they support microbial growth (Duffet et al., 1943; Fabian and Pivnick, 1953; Lee and Chandler, 1941; Page and Bushnell, …

Rb54-175 Farm Family Housing Needs And Preferences In Nebraska, Virginia Y. Trotter, Margaret I. Liston

University of Nebraska-Lincoln Extension: Historical Materials

Some farm families in Nebraska want to build new houses. Many others are planning to remodel. These families will be asking architects, engineers, builders, contractors, and dealers for plans that meet their needs. Thus, farmhouse plans should be developed that provide for the basic needs of all farm families and that are adaptable to special requirements of some families.

This 1954 bulletin reports the results of a survey of Nebraska farm family preferences, activities and possessions as they are related to housing needs. The study was part of a cooperative research project for the improvement of farm family housing in …

How The Mud-Puppies Were Named, Joseph P. Harris Jr.

Field and Laboratory

The many names under which the mud-puppies have been described or cited have caused some confusion. At least 33 'common" names and 29 scientific names have been given them at one time or another, not considering the names that have been applied to the species described since 1924.

Feeding Minerals To Livestock Important, Lawrence B. Embry

Agricultural Experiment Station Animal Husbandry Pamphlets

Minerals have many important functions in the body and their needs in livestock rations have been known for many years. Bone and teeth are composed chiefly of minerals which are necessary for their proper growth and development. In addition to these functions, minerals are necessary constituents of soft tissue and body fluids and play important roles in the regulation of body processes. In spite of the known need for minerals for a long time, much remains to be learned about specific requirements, mineral content of feeds, mineral balances and factors affecting these. It is recognized that the requirements of an …

Birds Observed In The Potholes Region During 1953-1954, Paul A. Johnsgard

Papers in Ornithology

From June 15-August 15, 1953 and from February 15 to August 15, 19 5 4 the writer did extensive field work in the Potholes Region of Grant County,Washington, gathering data for an ecological study of the vegetation and wildlife of that area. During this time considerable observations of the bird life were made, which for the most part were restricted to the area adjacent to O'Sullivan Dam and Potholes Reservoir.

Long-Tailed Jaeger Collected In Eastern Washington, Paul A. Johnsgard

Papers in Ornithology

An adult female Long-tailed Jaeger (Stercorarius longicaudus) was collected on Potholes Reservoir. Grant County. Washington, June 27. 1953. The bird was observed resting on the water near the middle of the reservoir. and as I approached. I noticed it was unable to fly. It attempted to fly several times as I came near, but seemed too exhausted to be able to leave the water. It was readily captured and brought to shore. Although in apparent good health. it refused to eat. and died that night. The bird was skinned, and is specimen number 53-216 in the Charles R. …

Polyvinyl Alcohol-Fixative-Adhesive For Small Helminths And Protozoa, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

Following the method of Brooke and Goldman (1949), the author was able to fix, mount and stain small helminths and parasitic protozoa of fish in polyvinyl alcohol-fixative smears. However, because there was much granular material in the PVA-Schaudin's mixture, AFA fixative was substituted for the Schaudin's. The PVA went into solution readily using this fixative. The solution was accomplished by adding 5 grams Elvanol #71-30¹ to 62 ml. of water, heating to 950 C. until dissolved and adding 5 ml. of acetic acid, 1-1/2 ml. of glycerine, 10 ml. of formaldehyde, and 30 ml. of 95 percent alcohol.

The Occurrence Of Ornithodiplostomum Ptychocheilus (Faust) (Trematoda: Strigeida) In Fish And Birds, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

The metacercaria of Ornithodiplostomum ptychocheilush as been reported by Faust (1918; Illinois Biological Monographs 4(1): 1-120) from mesenteries of the squawfish, Ptychocheilus oregonensis (Richardson), and by Hughes and Piszcek (1928; Journal of Parasitology 15: 58-62) and Van Haitsma (1930; Transactions of the American Microscopical Society 49: 140-153) in the northeastern sand shiner, Notropis deliciosus stramineus (Cope). Van Haitsma (1930) found the adults in mergansers, Mergus americanus, M. serrator, Lophodytes cucullatus, and the old squaw duck, Harelda hyemalis. He also reared the metacercaria to the adult in young domestic ducks. Lyster (1940; Canadian Journal of Research 18D: 79-82) reported …

Spermatogenesis In The Sand Crab Emerita Analoga, Mario Martin Menesini

University of the Pacific Theses and Dissertations

Crustacean spermatozoa are among the most peculiarly modified germ cells in the animal kingdom. Many of their striking cytological specializations may be observed in the sperm cells or Emerita analoga, the so-called sand crab. This animal has been used by the writer for studies on spermatogenesis and on spermatozoan behavior during the summer or 1951, 1952, and 1953 at the Pacific Marine Station.
