Project description:Adult male fish were exposed to the various temperature acclimation conditions as outlined in the published manuscript and RNA was extracted from fish at each time point as listed in the experiment set description.
Project description:Research on the effects of contaminants on fishes is often conducted on well-studied model test species, whose responses may be different than those of species of conservation concern. We used an oligonucleotide microarray to examine the effects of permethrin, a widely used pyrethroid pesticide, on a critically endangered fish species endemic to Northern California, the delta smelt (Hypomesus transpacificus). These results demonstrate the effects of a widely used pesticide on a sensitive fish species at concentrations below those that affect model test species.
