Acid-Base Regulation In Three Marine Teleosts: The Oyster Toadfish (Opsanus Tau), The Winter Flounder (Pseudopleuronectes Americanus), And The Long-Horned Sculpin (Myoxocephalus Octodecimspinosus), Dana Compton Mccullough

College of Graduate Studies: Theses & Dissertations (1964–2006)

In this study, three species of marine fish were exposed to a variety of dilute salinities in order to determine what effects exposure to diluted seawater may have on acid-base and ion balance. The oyster toadfish (Opsanus tau) and the winter flounder (Pseudopleuronectes americanus) are considered to be able to live in a broad range of salinities, euryhaline (Evans, 1979). The long-homed sculpin, Myoxocephalus octodecimspinosus, is considered to be a stenohaline fish, not able to withstand drastic changes in ambient salinity (Claibome and Evans, 1988).

Initially, toadfish exposed to 20 mM diluted seawater took up …

Biota Of Magazine Mountain (I): An Outline Of The Natural History Of Magazine Mountain, Robert T. Allen

Journal of the Arkansas Academy of Science

One plant and five invertebrate species are thought to be endemic to Magazine Mountain, Logan County, Arkansas. The mountain is the highest point in the Interior Highlands reaching 2,753 feet. Previous studies have recorded over 650 species of plants including (or in addition to) 27 fern species. The animal fauna is less well known. It is suggested that an inventory of the biota of the mountain could be completed within the foreseeable future. It is further suggested that such an inventory would be useful in answering questions relevant to understanding the evolution and biogeography of selected taxa in North America. …

Sodium/Proton Exhange In Membrane Vesicles From Crab (Callinected Sapidus And Carcinus Maenas) Gill, Robert Eric Shetlar

Master's Theses

The existence of a sodium-ion-for-hydrogen-ion exchange mechanism in the membranes of certain epithelial cells has been demonstrated by many investigators (Murer et al., 1976; Tsai et al., 1984; Seiler et al., 1985 ) • This mechanism has been shown to exchange one Na+ for one H+ (Aronson & Igarashi, 1986) and is thought to be more prominent in the brush-border membranes (Murer et al., 197 6; Reenstra et al., 1981 ; Ives et al., 1983) of mammalian kidney tubules and intestinal tissues than in basolateral membranes of these tissues. The roles the exchanger plays in the cell may include intracellular …

Oral History Collection

Susan Mehrtens' Note:

We have in this tape the recollections of one of the most prolific authors in the field of mouse mutants, an indefatigable co-worker of Margaret Dickey, Margaret Green and currently, Muriel Davison. Full of scientific terms, this tape reveals clearly Lane's thorough absorption in the field to which she has devoted nearly the last forty years of her life. Toward the end of this tape, Lane alludes to Earl Green's sexist attitude, which other women have also mentioned to me on and off tape. Lane also waxes eloquently here about her efforts to establish a hiera'rchy within …

Body Fluid Solutes Of Juveniles And Adults Of The Euryhaline Bull Shark Carcharhinus Leucas From Freshwater And Saline Environments, Thomas B. Thorson, C. Michael Cowan, Donald E. Watson

Investigations of the Ichthyofauna of Nicaraguan Lakes

Since the discovery of the phenomenally high urea content of the body fluids of cartilaginous fishes by Staedeler and Frerichs (1858), the unique osmoregulatory system of this vertebrate class has been studied by many investigators. In broad outline, the mechanisms are essentially similar in all three of the major subtaxa: the selachians, the batoids, and the holocephalans. A single exception is the genus Potamotrygon (fresh-water stingrays of South America and Africa), which has apparently lost the ability to concentrate urea even when transferred to salt water.

Taxonomic Studies On The Genus Podocotyle (Trematoda: Opecoelidae), Paul Clinton Edmiston

University of the Pacific Theses and Dissertations

The original intent of this study was to reinvestigate and confirm the validity of thirteen species of Podocotyle reported from Dillon Beach, California. Eight species were described by Park (1937) and five described by Johnson (1949-unpublished). Among these species basic similarities were evident in such features as: cirrus sac, seminal vesicle, body shape, extent and distribution of vitellaria, which indicated the possibility of conspecificity. Because four of these species (Podocotly blennicottusi, P. california, P. pedunculata, and P. pacifica) were also reported from fishes of the Pacific Northwest coast by Ching (1960), Pratt and McCauley (1961), Arai (1969), and Hall and …

Trap Manifested Behavior Trap Reflected Density Trap Reflected Distribution And Foods Consumed By Raccoons (Procyon Lotor L.) In Two Natural Areas Of Virginia, Elton L. Winslow

Biological Sciences Theses & Dissertations

A study was undertaken comparing populations of raccoons (Procyon lotor L.) in two natural areas of Virginia, one in the Piedmont physiographic province at Montpelier and the other in the coastal plain at Newport News. Comparisons were made with respect to differences in: (1) capture and recapture success, (2) relative trap reflected density, (3) trap reflected distribution with respect to aquatic habitat, and (4) in food consumption. Comparison of capture data indicated that capture success per 100 trap nights was much higher at Newport News (1.58) than at Montpelier (.76). However a similar comparison of recapture success per …

The Effect Of Soil Moisture On The Establishment Of Spruce Reproduction In British Columbia, Percy Munson Barr

Most of the field work has been conducted at the Aleza Lake Forest Experiment Station, in the valley of the Upper Fraser River, near the city of Prince George [British Columbia].

I. A series of twelve permanent plots (numbers 1 to 12) was established for the purpose of studying the occurrence of natural reproduction on various types of seed bed, under different densities of overwood and on northern and southern aspects. 2. A second series of four plots (numbers 17 to 20) was laid out in logged-off land for the purpose of studying the survival and growth of advance reproduction …

Some Marine Fish Trematodes Of Maine, Harold W. Manter

Harold W. Manter Laboratory of Parasitology: Library Materials

During the summer of 1924 a study of marine fish parasites was made at the Mount Desert Island (Maine, USA) Biological Laboratory. The present paper represents a preliminary report on the trematode group. Three new species of trematodes are described. Only brief consideration is here given to species already known. A later paper will deal more completely with these and related forms.
