| seasonal, interannual, and long-term variation in sport fish contamination, san francisco bay. | this study documents changes in contamination over time at seasonal, interannual, and decadal time scales for sport fish collected in san francisco bay. samples from seven fish species were prepared according to common consumption practices (muscle fillets either with or without skin) and analyzed for trace metals (mercury and selenium) and trace organochlorine contaminants (pcbs, ddts, chlordanes, and dieldrin). in 2000, sport fish samples exceeded human health screening values for mercury, pcb ... | 2005 | 15589247 |
| persistence of historical population structure in an endangered species despite near-complete biome conversion in california's san joaquin desert. | genomic responses to habitat conversion can be rapid, providing wildlife managers with time-limited opportunities to enact recovery efforts that use population connectivity information that reflects predisturbance landscapes. despite near-complete biome conversion, such opportunities may still exist for the endemic fauna and flora of california's san joaquin desert, but comprehensive genetic data sets are lacking for nearly all species in the region. to fill this knowledge gap, we studied the ra ... | 2017 | 28370723 |
| contaminant concentrations in sport fish from san francisco bay, 1997. | in 1997, seven sport fish species were sampled from seven popular fishing areas in san francisco bay. mercury exceeded a human health screening value in 44 of 84 (52%) samples. all collected samples of leopard shark and striped bass exceeded the mercury screening value of 0.23 microg/g wet weight. pcbs exceeded the screening value in 51 of 72 (71%) samples. ddt, chlordane, and dieldrin, had lower numbers of samples above screening values: 16 of 72 (22%) for ddt, 11 of 72 (15%) for chlordanes, an ... | 2002 | 12474973 |
