ABSTRACT: Characterization of the complete chloroplast genome of Polyspora tiantangensis (Theaceae), an endemic and endangered species in southwestern China
Project description:The delta smelt (Hypomesus transpacificus) is a pelagic fish species endemic to the Sacramento-San Joaquin Estuary in Northern California, listed as endangered under both the USA Federal and Californian State Endangered Species Acts and acts as an indicator of ecosystem health in its habitat range. Interrogative tools are required to successfully monitor effects of contaminants upon the delta smelt, and to research potential causes of population decline in this species. We used microarray technology to investigate genome-wide effects in 57-day old larvae after a 4-day exposure to ammonia; one of multiple contaminants arising from wastewater treatment plants and agricultural runoff. Genomic assessments were carried out between larvae exposed to 10 mg/L total ammonium; the lowest observed effect concentration (LOEC), and controls.

Project description:The delta smelt (Hypomesus transpacificus) is a pelagic fish species endemic to the Sacramento-San Joaquin Estuary in Northern California, listed as endangered under both the USA Federal and Californian State Endangered Species Acts and acts as an indicator of ecosystem health in its habitat range. Interrogative tools are required to successfully monitor effects of contaminants upon the delta smelt, and to research potential causes of population decline in this species. We used microarray technology to investigate genome-wide effects in 47-day old larvae after a 7-day exposure to ambient water samples from the Sacramento River at a monitoring field station (Hood) situated 8 miles downstream of the Sacramento regional Wastewater Treatment Plant. Genomic assessments were carried out on surviving organisms and contrasted to laboratory controls.

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.
