Copper sensitivity of Gonyaulax tamarensis1
The copper sensitivity of the dinoflagellate Gonyuulax tamarensis was examined in artificial seawater medium. Two short term responses of the organism to copper toxicity are rapid loss of motility and reduced photosynthetic carbon fixation. The chelators tris(hydroxymethylamino)methane (Tris) and cthylenedinitrilotetraacetic acid (EDTA) were used to dcmonstrate that copper toxicity is a unique ...
متن کاملInfluence of developmental stage on sensitivity to ammonium nitrate of aquatic stages of amphibians.
In static renewal experiments, we studied how developmental stage influences the effect of ammonium nitrate on embryonic and larval stages of anuran amphibians. The observed lethal effects caused by ammonium nitrate increased with both concentration and duration of exposure. Significant differences were observed in sensitivity to ammonium nitrate as a function of developmental stage in Discoglo...
متن کاملSensitivity of Mediterranean woody seedlings to copper, nickel and zinc.
The restoration of heavy metal contaminated areas requires information on the response of native plant species to these contaminants. The sensitivity of most Mediterranean woody species to heavy metals has not been established, and little is known about phytotoxic thresholds and environmental risks. We have evaluated the response of four plant species commonly used in ecological restoration, Pi...
متن کاملSensitivity of marine microalgae to copper: the effect of biotic factors on copper adsorption and toxicity.
Microalgae are sensitive indicators of environmental change and, as the basis of most freshwater and marine ecosystems, are widely used in the assessment of risk and development of environmental regulations for metals. However, interspecies differences in sensitivity to metals are not well understood. The relationship between metal-algal cell binding and copper sensitivity of marine microalgae ...
متن کاملAn examination of amphibian sensitivity to environmental contaminants: are amphibians poor canaries?
Nearly two decades ago, the global biodiversity crisis was catapulted to the front pages of newspapers with the recognition of worldwide amphibian declines. Amphibians earned their appellation, 'canaries in a coal mine', because of apparent high sensitivity to human-mediated environmental change. The most frequently cited causes for high susceptibility include permeable skin, a dual aquatic-ter...
