Our understanding of the response of vascular, terrestrial plants to nitrogen (N) addition is advanced and provides the foundation for modern agriculture. In comparison, information on responses of marine macroalgae to increased nitrogen is far less developed. We investigated how in situ pulses of nitrate (NO3 −) affected the growth and N physiology of(More)
Keywords: Whitewater park Fish passage Barrier Hydraulic modeling Flow complexity Design A B S T R A C T Evaluating and designing channel spanning structures for successful fish passage requires description of hydraulic conditions at scales meaningful to fish. We describe novel approaches combining fish movement data and hydraulic descriptions from a(More)
Electromyographic detection of increased neuromuscular conduction latency that follows electrostimulation of spinal nerves has been used widely as a clinical tool for detection of ischemic muscle injury. We hypothesized that a biochemical marker for stagnant hypoxia provides more direct evidence for evaluating severity and monitoring resolution of ischemic(More)
