Swimming behavior as an indicator of sublethal toxicity in fish
Swimming behavior of fish is impaired by exposure to a diversity of contaminants. Gross aberrations in swimming can be qualitatively assessed while subtle changes in swimming behavior arising from… Expand
Photoenhanced toxicity of a carbamate insecticide to early life stage anuran amphibians
- Angela Zaga, E. Little, C. F. Rabeni, M. Ellersieck
- Biology
- 1 December 1998
Aican clawed frog (Xenopus laevis) and gray tree frog (Hyla versicolor) embryos and tadpoles were exposed to sublethal levels of carbaryl, a broad-spectrum insecticide, and ultraviolet radiation to… Expand
Physiological measures of neurotoxicity of diazinon and malathion to larval rainbow trout (Oncorhynchus mykiss) and their correlation with behavioral measures
- S. Beauvais, S. B. Jones, S. Brewer, E. Little
- Biology
- 1 July 2000
Relations between neurotoxicants and changes in physiological parameters and behavior were investigated in larval rainbow trout (RBT; Oncorhynchus mykiss) exposed to sublethal concentrations of two… Expand
Behavioral Dysfunctions Correlate to Altered Physiology in Rainbow Trout (Oncorynchus mykiss) Exposed to Cholinesterase-Inhibiting Chemicals
- S. Brewer, E. Little, A. J. DeLonay, S. Beauvais, S. Jones, M. Ellersieck
- Biology, Medicine
- Archives of environmental contamination and…
- 2001
We selected four metrics of swimming behavior (distance swam, speed, rate of turning, and tortuosity of path) and the commonly used biochemical marker, brain cholinesterase (ChE) activity, to assess… Expand
Toxicity and bioaccumulation of waterborne and dietary selenium in juvenile bluegill (Lepomis macrochirus)
- L. Cleveland, E. Little, D. Buckler, R. H. Wiedmeyer
- Biology
- 1 December 1993
Abstract Juvenile bluegill (Lepomis macrochirus) were exposed to waterborne selenium as a 6:1 mixture of selenate to selenite (as Se) for 60 d and to dietary seleno- l -methionine for 90 d. Measured… Expand
Behavioral indicators of sublethal toxicity in rainbow trout
- E. Little, R. D. Archeski, B. A. Flerov, V. Kozlovskaya
- Chemistry, Medicine
- Archives of environmental contamination and…
- 1 May 1990
Four measures of behavior-spontaneous swimming activity, swimming capacity, feeding behavior, and vulnerability to predation-were assessed as indicators of sublethal toxicity in rainbow trout… Expand
The effect of chronic chromium exposure on the health of Chinook salmon (Oncorhynchus tshawytscha).
- A. Farag, T. May, +4 authors L. Cleveland
- Biology, Medicine
- Aquatic toxicology
- 10 March 2006
This study was designed to determine fish health impairment of Chinook salmon (Oncorhynchus tshawytscha) exposed to chromium. Juvenile Chinook salmon were exposed to aqueous chromium concentrations… Expand
Behavioral avoidance: Possible mechanism for explaining abundanc and distribution of trout species in a metal‐impacted river
- J. Hansen, D. Woodward, E. Little, A. DeLonay, H. Bergman
- Chemistry
- 1 February 1999
Behavioral avoidance of metal mixtures by rainbow trout (Oncorhynchus mykiss) was determined in the laboratory under water quality conditions that simulated the upper Clark Fork River, Montana, USA.… Expand
Multiple stressors in amphibian communities: effects of chemical contamination, bullfrogs, and fish.
- Michelle D. Boone, R. D. Semlitsch, E. Little, Meaghan C. Doyle
- Biology, Medicine
- Ecological applications : a publication of the…
- 2007
A leading hypothesis of amphibian population declines is that combinations of multiple stressors contribute to declines. We examined the role that chemical contamination, competition, and predation… Expand
Metals-contaminated benthic invertebrates in the Clark Fork River Montana: effects on age-0 brown trout and rainbow trout
- D. Woodward, A. Farag, +4 authors F. Barrows
- Biology
- 1 September 1995
Benthic organisms in the upper Clark Fork River have recently been implicated as a dietary source of metals that may be a chronic problem for young-of-the-year rainbow trout (Oncorhynchus mykiss). In… Expand
