Hermaphroditism in Fundulus heteroclitus

Warm acclimation improves hypoxia tolerance in Fundulus heteroclitus.

Human activities are increasing both the frequency of hypoxic episodes and the mean temperature of aquatic ecosystems, but few studies have considered the possibility that acclimation to one of these stressors could improve the ability to cope with the other stressor. Here, we used Atlantic killifish, Fundulus heteroclitus, to test this hypothesis. Hypoxia tolerance was measured as time to loss...

Parasite Infection Mediates Trait Tradeoffs in Fundulus heteroclitus

Benzo[a]pyrene effects on reproductive endpoints in Fundulus heteroclitus.

Benzo[a]pyrene (BaP) is a polycyclic aromatic hydrocarbon (PAH) that has been implicated in modulating aromatase enzyme function with the potential to interrupt normal reproductive function. The aim of this study was to use a fish model, Fundulus heteroclitus, to assess whether BaP exposure adversely impacts reproduction. Adult fish were exposed to waterborne BaP nominal concentrations of (0, 1...

Trivalent chromium alters gene expression in the mummichog (Fundulus heteroclitus).

Mummichogs (Fundulus heteroclitus) were used as a model fish species to study the effects of trivalent chromium exposure. To ascertain chromium's effects, we examined altered gene expression by differential display between fish exposed in the laboratory and fish collected from a chromium-impacted estuarine site. Twenty differentially expressed genes were found from either laboratory-exposed fis...

Endocrinological Studies on the Euryhaline Killifish, Fundulus Heteroclitus (Linn.) **

The common killifish of the eastern United States, Fundulus heteroclitus (Linn.), is widely employed as an experimental animal by zoologists, em-bryologists, and comparative physiologists. The late Dr. Myron Gordon8' points out that it is a hardy species of convenient size, readily caught in tidal pools but not usually bred in aquaria for purposes of raising the stock. Dr. Gordon warns against ...
