The Experimental Histopathology Of The "Tumor" On The Brain Of The Stickleback Caused By Diplostomum Baeri Eucaliae Hoffman And Hundley, 1957 (Trematoda: Strigeoidea)), Glenn L. Hoffman, James B. Hoyme

United States Fish and Wildlife Service: Publications

The structure of the "tumor" on the brain of the stickleback fish, Eucalia inconstans (Kirtland) caused by Diplostomum baeri eucaliae, has been briefly reported (Hoffman and Hoyme, 1957; Hoffman and Hundley, 1957) and consists of an outgrowth of the columnar epithelium of the choroid plexus which surrounds the metacercariae at the postero-lateral aspect of the optic lobes. The present report deals with the experimental development of the "tumor."
No record of a comparable structure in fish could be found and the reader is referred to our earlier paper (Hoffman and Hundley, 1957) for further introduction, and materials and methods.

Studies On The Life-Cycle Of Ornithodiplostomum Ptychocheilus (Faust) (Trematoda: Strigeoieda) And The "Self Cure" Of Infected Fish*, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

During the summer of 1956 the following fish of Turtle River (Arvilla), North Dakota were found infected with the Neascus metacercaria of Ornithodiplostomum ptychocheilus (Faust): Northern common shiner (Notropis cornutus frontalis), bigmouth shiner (Notropis d. dorsalis), creek chub (Semotilus a. atromaculatus), fathead (Pimephales p. promelas), and johnny darter (Boleosoma n. nigrum). The cysts were usually very numerous (up to 400 per fish) in the mesenteries of the chub and common shiner; they were also very numerous in the cranial cavity and in the fat bodies behind the eyes of the …

Taxonomic Studies On Adult And Larval Ascidians From California, Robert Christian Haugsten

University of the Pacific Theses and Dissertations

The primary purpose of this research is to further morphological studies on larval ascidians and to encourage greater reliance on larval structures in ascidian taxonomy. This may necessitate some revisions in current classifications, but it is hoped that such revisions will lead to a better understanding of the group. Some general considerations of ascidians are here included for the benefit of those who may not be familiar with them. All specimens used in this study were collected at the Pacific Marine Station area at Dillon Beach, California, during June, July, and August of 1957.

Evaluation Of Ground Corncobs And Corncob Components As Nutritive Materials In Rations For Beef Cattle, J. Matsushima, T. W. Dowe, V. H. Arthaud

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Two feeding trials were conducted to (1) determine the comparative feeding values of ground corncobs with two fractions of the corncobs--namely, the beeswing and woodyring, and (2) to compare different factors that might affect the utilization of ground corncobs and cob fractions in wintering rations for beef cattle.

Studies On The Periodicity Of Certain Plankton Species Of Salem Lake, Gene A. Pratt

Theses and Dissertations

Plankton samples were taken periodically from one station in Salem Lake from the fall of 1955 through the winter of 1957. Other data including the pH, dissolved oxygen content, turbidity, brightness of day, temperature, and time of day were recorded at the time of each collection. The plankton samples were centrifuged and preserved in a 4% formalin solution. They were later examined microscopically, and density, percent density, and percent frequency calculations were made from them for ten selected species and for the five phyla which they represent.

Observations On The White-Faced Ibis, Plegadis Chihi, In Louisiana, Horace William Belknap

LSU Historical Dissertations and Theses

The eight-month study deals with the White-faced Ibis, Plegadis chihi, in southwestern Louisiana. It affirms the absence of the closely related Glossy Ibis, Plegadis falcinellus, as a breeding bird in that area today. Data on feeding habits, social behavior, nesting cycles, and plumage changes in chihi are presented as a step toward clarifying the relationship of these two puzzling forms of ibis; but the full significance of these findings cannot be ascertained until more is known about the habits of falcinellus. The most important conclusions concern plumage changes. It is shown that published descriptions of plumage and molt in chihl …
