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 …

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 …

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 Eight species were described by Park (1937) and five described by Johnson (1949-unpublished).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 …
