Mummichogs or killifish (Fundulus heteroclitus) are abundant estuarine fish that can tolerate widely varying environmental conditions. They are found in some highly contaminated sites, and their development of tolerance to toxicants has been studied. Populations have developed resistance to methylmercury, kepone, dioxins, polychlorinated biphenyls, and polyaromatic hydrocarbons. This article describes what is known about their tolerance, and discusses similarities and differences among these…

Adaptation of the Estuarine Fish Fundulus heteroclitus (Atlantic Killifish) to Polychlorinated Biphenyls (PCBs)

It is shown here that tolerance to PCB126 is extreme, with some mechanistic similarities among these four least-sensitive killifish populations, however, these populations do not respond identically to each other, and in at least one population, tolerance appears to degrade over the F1 and F2 generations tested.

Population genetic structure of a nonmigratory estuarine fish (Fundulus heteroclitus) across a strong gradient of polychlorinated biphenyl contamination

Results indicated neither significant loss of genetic diversity nor alteration of allele frequencies for populations of F. heteroclitus in NBH, indicating other potential genetic effects of these stressors on resident populations are suggested.

Paracelsus' Dictum, addressing human toxicology, forms the basis for both modern medicine and ecotoxicology. The Dictum can be paraphrased as ‘The right dose makes the poison.’ What this means in…

Desiccation resistance in embryos of the killifish, Fundulus heteroclitus: single embryo measurements.

Data support the hypothesis that low permeability embryonic compartment surface membranes retard water loss significantly and promote prolonged survival of these embryos during desiccation and show this mechanism cannot completely account for the survival of severely desiccated embryos and that there must also be complementary cellular responses.

Effects of the toxic dinoflagellate, Alexandrium fundyense on three species of larval fish: a food‐chain approach

Sublethal behavioural effects of exposure to paralytic shellfish toxins from the toxic dinoflagellate Alexandrium fundyense were investigated in newly settled winter flounder, larval sheepshead minnow and larval mummichog through a novel food-chain approach with zooplankton as vectors.

Impacts of multiple stressors on growth and metabolic rate of Malaclemys terrapin

It is shown that PCB 126 disrupts the ecophysiological mechanisms that affect life history traits and thus ultimately could alter population structure and dynamics and enriches the understanding of the environmental toxicology of reptiles.

Adaptations of wild populations of the estuarine fish Fundulus heteroclitus to persistent environmental contaminants

It is concluded that DLC contamination in NBH has contributed to the selection of fish that are resistant to the short-term toxic effects of these environmental-contaminant exposures, and this adaptation may be a critical mechanism by which fish populations persist in this highly contaminated site.

Variation in Response to Methylmercury by Killifish ( Fundulus heteroclitus ) Embryos

Some female killifish from Montauk, N.Y., produce eggs that are much more resistant to the craniofacial, cardiovascular, and skeletal effects of 0.05 ppm methylmercury than eggs of other females.

The contaminants in PC may cause the differences in thyroid structure and function, which may be partly responsible for the behavioral differences between fish from the polluted PC and from the reference TK.
