Project description:Linking transcriptional responses to organismal tolerance reveals mechanisms of thermal sensitivity in a mesothermal endangered fish
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.
