To examine whether stream nitrogen concentrations in forested reference catchments have
changed over time and if patterns were consistent across the USA, we synthesized up to 44 yr
of data collected from 22 catchments at seven USDA Forest Service Experimental Forests.
Trends in stream nitrogen presented high spatial variability both...

The oxygen concentration in a stream is an important
parameter of water quality. Changes in oxygen concentrations
can affect various stream organisms including fish.
Foresters have become concerned with predicting the impacts
of forest activities on oxygen levels in streams. Slash,
which accumulates in streams as a result of harvesting...
These data contain temperature readings from dataloggers launched in Deer Creek, Flynn Creek, and Needle Branch from 2006 to 2010. These loggers were apart of the Alsea Watershed Revisisted Study Revisited articles, but the data was incomplete due to logging gaps, temperature spikes, or other issues. The "Thermistor Functionality" datasets...
The heat inactivation of the psychrophilic marine bacterium,
Ant-300, was investigated in terms of permeability control, glucose
uptake, and respiration. Extensive leakage of 14C-cellular material
occurred at 13 C, the maximum growth temperature of the organism.
Protein and RNA were released from the cells in significant
quantities. Inhibition of glucose...
Cells of the marine bacterium, Ant-300, accumulate loosely bound
amino acids during amino acid uptake. The fraction of amino acid taken
up that exists in the loosely bound state depends on the substrate in
question. Shock treatment studies indicate that, in general, the initial binding, uptake, and retention of amino...
