Observations On Eimeria From Ambystoma Tigrinum, With Descriptions Of Four New Species, L. H. Saxe

Proceedings of the Iowa Academy of Science

There appear to be only three records of coccidia of the genus Ezmeria from North American Amphibia. Rankin (1937) reported Eimeria ranarum from Ambystoma opacum. Walton (personal communication) says that his record (1942) of Eimeria from Ambystoma is based upon a letter from Dr. Harold Kirby who stated that he had seen E. ranarum from A. opacum. Doran (1953) reported Eimeria grobbeni from Taricha torosa. The author, on several occasions, has noted the presence of coccidian oocysts in the rectal contents of salamanders. Four species of Eimeria have been recognized in material from Ambystoma tigrinum (Green) and will be described …

Courtship Activities Of The Anatidae In Eastern Washington, Paul A. Johnsgard

Papers in Ornithology

The many interesting and sometimes spectacular aspects of waterfowl courtship have been observed and recorded by several writers. Among the best and most complete descriptions are those of Bent (1923, 1925), Townsend (1910, 1916), Wetmore (1920), and Hochbaum (1944). However, for the most part these are unillustrated, deal with only a few species, or are based on limited observations.

Quantitative Relationships Of Terrestrial Mosses With Some Coniferous Forests At Mt. Rainier National Park, N. Higinbotham, Betty Wilson Higinbotham

Butler University Botanical Studies

Relatively few studies have been made on the correlation of moss societies with tree species in climax associations in North America; this is true despite the fact that in Europe moss unions have been accorded considerable importance along with societies of larger plants in delimiting phytocoenoses. The present study is an attempt to characterize as accurately as possible the terrestrial moss communities of typical climax stands in a given area, largely in Mt. Rainier National Park, and to discover how closely related bryophyte occurrence, frequency, and coverage may be to the societies of higher plants.

The Parasite Of Necturus, Joseph P. Harris Jr.

Field and Laboratory

In all, some fifteen species of animals parasitic upon Necturus have been reported. It is probable that none is exclusively a parasite of Necturus, for nearly all have also been reported from other animals.

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 …

A Study Of The Ecological Distribution Of Income, Education And Occupation In Omaha, Nebraska, Francis A. Weathers

Student Work

A social ecological study involves the spatial, selective and distributive functions and relations of human beings in a given geographical and cultural area. In the present study, Omaha is viewed as an ecological area for purposes of the following analysis. Briefly stated, the purpose of this study is to present the ecological distribution of income, education, and occupation in the several census tracts in Omaha, Nebraska. Following the pattern of ecological studies in general, it is assumed that such characteristics will be distributed in a pattern. Ecological distribution, of these indices, refers to the differential distributionof Income, education, and occupation …

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.

An Investigation Of Relationship Between Personality Adjustment And Disparity Of Verbal And Performance Intelligence, Herman Edward Frick

University of the Pacific Theses and Dissertations

The problem of the thesis was as follows: On a selected group of children, to what extent are differences between scores of verbal and performance intelligence tests useful as group and individual measures of adjustment? Adjustment was measured by A Test of Personality Adjustment by Carl Rogers. Verbal and performance intelligence were measured by the Wechsler Intelligence Scale for Children. Differences between scores of verbal and performance tests were measured by a specified criterion, disparity. The problem, findings, and interpretations were limited to these criteria.

Secondary Succession In Stands Of Red Maple - Sweet Gum - Beech Forests In Ripley County, Indiana, J. E. Potzger, A. N. Liming

Butler University Botanical Studies

The vegetation of the leached Illinoian till plain has been described in detail by Braun, Keller, McCoy, and the progress of secondary succession in these habitats has been considered quantitatively by Potzger and Potzger, and in a more general way by Chapman. Realizing the insecure accuracy of empirical field impressions, the present quantitative study of seven stands on Illinoian till plain forests in the process of developing either from lumbering distrubance or from cleared land was undertaken.

Ecological Observations Upon The Fresh-Water Sponges In Dallas County, Texas, E. P. Cheatum, Joseph P. Harris Jr.

Field and Laboratory

Published distributional and ecological data on the fresh-water sponges of Texas are meager. Besides Marcus Old's (1936) report on sponges collected by us the only other published report for this region is a description of Asteromyenia plumosa by Weltner (1895) from McKinney, Collin County, Texas. Dr. Old reported Spongilla fragilis from a small pond 1½ miles west of Dallas, and from Parson's Slough near Seagoville in Dallas County; Trochospongilla horrida from Elm Fork of the Trinity River, Dallas County; Asteromyenia plumosa from White Rock Lake, Dallas; and Ephydatia crateriformis from the East Fork of the Trinity River in Rockwall County. …

Notes Of The Ecology Of The Fresh-Water Mussels Of Dallas County, Louis B. Read, Kelly H. Oliver

Field and Laboratory

The late John K. Strecker of the Baylor University Museum catalogued the Naiades of Texas in 1931. Since then, but little has been added to our knowledge of these mollusks in Texas. We need now, especially, studies on the general ecology of Texan species, with a modern revision of names, careful comparison of the synonymy, and close identification of Texas specimens in the museums. Last summer (1951) we made an ecological study of Parson's Slough in the southeastern part of Dallas County. In our work we gathered much information on the bivalve mollusks. Other data later gathered from this locality …

Polarographic Determination Of Nitrate In Sea Water, David Tung-Whei Chow, Rex J. Robinson

Journal of Marine Research

A new and accurate method for the determination of nitrate in sea water, based on the pola.rographic reduction of nitrate in the presence of uranyl ions, is presented. Sulfate ions depress the reduction current by a definite proportion, depending on the chlorinity of the water sample; for chlorinities in the range of 14 to 19 ‰, this effect is rather constant. Fluoride interferes strongly with the reduction of nitrate, but aluminum or zirconyl salts may satisfactorily eliminate this effect. Other interfering ions and preservatives are also discussed. A procedure for the determination of nitrate in sea water ha.s been proposed …

Further Observations On The Breeding And Migration Of The Bermuda Spiny Lobster, Panulirus Argus, W. H. Sutcliffe Jr.

The Ecology Of Mosquito Borne Viruses, Carl M. Eklund

United States Public Health Resources

The ecology of a mosquito borne virus involves a consideration of the growth of the virus within the vertebrate and arthropod hosts, the reaction of these hosts to the presence of the virus, and the vertebrate-arthropod associations which are necessary for the dissemination and maintenance of the virus. Little is known of the physiological properties of a particular host and virus which permit multiplication of the virus. In this review stress will be laid u pon studies which attempt to discover the mechanisms in nature which maintain these viruses. The first section will relate to the geographical distribution and time …
