Isolation of compounds from bleached kraft mill recovery condensates associated with reduced levels of testosterone in mummichog (Fundulus heteroclitus).

Natural and anthropogenic factors shape metazoan parasite community structure in mummichog (Fundulus heteroclitus) from two estuaries in New Brunswick, Canada.

Previously published multidisciplinary studies in the Miramichi and Bouctouche rivers (New Brunswick, Canada) noted significant changes in fish health parameters, including elevated tissue levels of organic contaminants and a wide range of physiological disturbances, in mummichog Fundulus heteroclitus (L.) from a site on the Miramichi River that received bleached kraft pulpmill and municipal ef...

Genetic structure of Fundulus heteroclitus from PAH-contaminated and neighboring sites in the Elizabeth and York Rivers.

Population genetic characteristics of mummichog, Fundulus heteroclitus, from the heavily industrialized Elizabeth River and nearby York River (Virginia USA) were assessed relative to sediment PAH concentrations. Allozyme genotype frequencies for all loci were consistent with random mating expectations at each locality and age class. Fish from all sites had comparable levels of enzyme polymorphi...

Genetic structure and mtDNA diversity of Fundulus heteroclitus populations from polycyclic aromatic hydrocarbon-contaminated sites.

Genetic structure and diversity of mummichog (Fundulus heteroclitus) populations were investigated using mitochondrial DNA (mtDNA) sequences. Forty-six haplotypes were identified among 208 mummichog from the Elizabeth and York Rivers in Virginia, USA. No evidence of decreased gene or nucleotide diversity for mummichog from polycyclic aromatic hydrocarbon (PAH)-contaminated sites was observed. H...

Distribution and habitat preferences of the introduced mummichog Fundulus heteroclitus (Linnaeus) in southwestern Spain

Hg- and Cu-induced hepatocellular changes in the mummichog, Fundulus heteroclitus.

To investigate mechanisms by which the mummichog (F. heteroclitus) successfully withstands heavy metal pollution, fish were treated with Hg2+ at up to 0.10 mg/L, Cu2+ at up to 1.0 mg/L, or combinations of Hg2+ and Cu2+. In earlier work, protein analysis of liver indicated that most of the cytosolic Cu is bound to the sulfhydryl-rich metallothionein, but that Hg is not associated with cytosolic ...
