In the first quarter of 2010, the Broadcast TV networks sampled in the study streamed 380 million videos, with Web media brands coming up close behind at 326 million video streams.
It found traces of methylmercury, a form of mercury that is readily absorbed, in every fish sampled in 291 streams across the country.
Loss of Fe is most likely due to transport of micron-sized particles that are not sampled by porous-cup lysimeters, but which are sampled in stream and ground waters.
In addition, we found some evidence for greater pathogen load among the kokanee sampled in stream-spawning habitats, suggesting a possible evolutionary advantage to shore-spawning that warrants further study.
A single fish (BL7300) carrying a haplotype that nested well within the Northern Inland clade was sampled in a northern Bonneville Basin stream at the Utah/Idaho border.
Last year the U.S. Geological Survey released data showing that 80% of 139 streams sampled in 30 states contained traces of hormones, steroids, and other drugs.
In the second case, population GUAR, sampled in 2001, clustered to a great extent with San Juan populations but also showed considerable admixture with Cariaco genes, whereas CAS, sampled in 2011 from the same stream, grouped with the San Juan drainage populations.
For the Boot system with lower replication per locus in the stream sample (see above), 15 of the 35 singleton loci represented unreplicated RAD sequences.
Wet digestion and dissolution protocol (modified from Makishima and Nakamura [68]) for trace metals in the stream sediment samples was as follows.
Conductivity, pH, water temperature, and oxygen concentration were measured directly in the stream during every sampling event.
