In a typical experiment, the two streams merging in the central channel contained buffer with ATP (0 500 μM, blue stream; Figure 1C and Figure 1 figure supplement 3), and buffer with XPD helicase (6 nM, red stream).
We simulated the pesticide entry on the landscape level at 737 sites in small streams situated in the central lowland of Germany with winter wheat, barley, and sugar beat as the main agricultural crops.
Pesticides are a major burden for stream ecosystems in the central European cultivated landscape.
Because of the spatial limitations of electrophysiological techniques, however, the mechanisms underlying information processing of the natal stream odor in the central nervous system of salmon, especially in the telencephalon, has not been completely elucidated.
Like more than 300 other streams in the south-central region of the country, the creek waters are made up largely of wastewater that is legally regulated and discharged from a reclamation plant, Brooks notes.
To date, studies have not determined if the olfactory memory of the natal stream is stored in the central or peripheral olfactory nervous system in salmon.
Cedar River, nonnavigable stream in the north-central United States, flowing from southeastern Minnesota southeasterly across Iowa and joining the Iowa River about 20 miles (32 km) from the Mississippi River.
Rock River, nonnavigable stream in the north-central United States that originates north of Horicon Marsh, near Brandon in Fond du Lac county, eastern Wisconsin, and flows in a generally southwesterly direction to join the Mississippi River at Rock Island, Illinois.
In the present study, BOLD fMRI was used to investigate natal stream odor information processing in the central nervous system by measuring the response to natal stream water in the olfactory bulb and telencephalon of lacustrine sockeye salmon.
I started on the analytical fast stream where I worked in the central management unit for the government operational research service, and then moved into an analytical team in HMRC.
