Comparisons of Salinity Tolerances and Osmotic Regulatory Capabilities in Populations of Sailfin Molly (Poecilia latipinna) from Brackish and Fresh Waters
- F. Nordlie, Dennis C. Haney, S. Walsh
- Environmental Science
- 18 August 1992
Isolation in nature of populations in fresh and brackish waters has not greatly altered their physiological capabilities with respect to ambient salinity, and plasma osmotic concentrations of the two groups were not significantly different at common ambient salinities.
Urban Influences on Stream Chemistry and Biology in the Big Brushy Creek Watershed, South Carolina
- Gregory P. Lewis, Jennifer D. Mitchell, C. B. Andersen, Dennis C. Haney, M. Liao, K. A. Sargent

- 31 January 2007
The lack of significant differences in fish abundance and diversity between urban and rural sites may indicate that urban development in the Big Brushy Creek watershed has not yet degraded habitat conditions greatly for stream fishes.
Physiological and Hematological Changes in Chum Salmon Artificially Infected with Erythrocytic Necrosis Virus
- Dennis C. Haney, D. Hursh, M. C. Mix, J. Winton
- Medicine
- 1992
The hematology data indicated that erythrocytes of infected fish had highermean corpuscular volume, depressed mean corpuscular hemoglobin concentration, and less fragile ery Throcyte fragility than did control fish.
Influence of Environmental Salinity on Routine Metabolic Rate and Critical Oxygen Tension of Cyprinodon variegatus
- Dennis C. Haney, F. Nordlie
- Environmental SciencePhysiological Zoology
- 1 September 1997
The variations in routine metabolic rate and critical oxygen tension at high salinities suggest that C. variegatus responds to highSalinities by reducing energy expenditures, effectively increasing the time that individuals can tolerate hypersaline conditions.
The influence of ambient salinity on routine metabolism in the teleost Cyprinodon variegatus Lacepède
- F. G. Nordlie, S. Walsh, Dennis C. Haney, T. Nordlie
- Environmental Science
- 1991
It is suggested that routine metabolism is depressed at elevated salinities by reduced O, transfer, a consequence of maintenance of hydromineral balance in hypersaline waters.
Osmoregulation in the sheepshead minnow, Cyprinodon variegatus: Influence of a fluctuating salinity regime
- Dennis C. Haney
- Environmental Science
- 1 December 1999
Fish previously exposed to large salinity fluctuations regulated plasma osmolality better than fish that previously had experienced no change or small changes in salinity, and increasing salinity had a greater impact on osmoregulation than did decreasing salinity.
Adaptations in salt marsh teleosts to life in waters of varying salinity
- F. Nordlie, Dennis C. Haney
- Environmental Science
- 1998
Salinity tolerances and osmotic regulatory capabilities among these teleosts, and related differences in their physiological responses to patterns of utilization of salinity‐habitat zones, fresh to hypersaline waters, are examined.
Plasma Osmotic Regulation and Routine Metabolism in the Eustis Pupfish, Cyprinodon variegatus hubbsi (Teleostei: Cyprinodontidae)
- F. Jordan, Dennis C. Haney, F. Nordlie
- Environmental Science, Biology
- 18 August 1993
The Eustis pupfish, although long isolated in fresh waters, has retained the physiological plasticity generally characteristic of the cyprinodontoids.
Influence of salinity and temperature on the physiology of Limia melanonotata (Cyprinodontiformes: Poeciliidae): A search for abiotic factors limiting insular distribution in Hispaniola
- Dennis C. Haney, S. Walsh
- Environmental Science
- 2003
The results suggest that L. melanonotata may reduce energy expenditures at environ- mental extremes to tolerate harsh conditions for extended periods, and approaches the upper extreme in salinity and temperature tolerances known for poeciliids.
Variation in thermal tolerance and routine metabolism among spring- and stream dwelling freshwater sculpins (Teleostei: Cottidae) of the southeastern United States
- S. Walsh, Dennis C. Haney, C. M. Timmerman
- Environmental Science
- 1 June 1997
The results suggest that some spring-adapted populations or species may be more stenothermal than stream-dwelling congeners, but a greater understanding of the interactions of other physical and biological factors is required to better explain micro- and macro habitat distributions of eastern North American sculpins.
