Pool-Type Fishways: Two Different Morpho-Ecological Cyprinid Species Facing Plunging and Streaming Flows
Fish are particularly sensitive to connectivity loss as their ability to reach spawning grounds is seriously affected. The most common way to circumvent a barrier to longitudinal connectivity, and to mitigate its impacts, is to implement a fish passage device. However, these structures are often non-effective for species with different morphological and ecological characteristics so there is a ...
متن کاملEffects of Aggradation and Degradation on Riffle-Pool Morphology in Natural Gravel Channels, Northwestern California
After the flood of December 1964, 12 gaging sections in northern California widened as much as 100% and aggraded as much as 4 m, and then degraded to stable levels during a period of 5 years or more. As channels aggraded, bed material became finer, and low to moderate flow through gaging sections in pools became shallower, faster, and steeper. Comparisons of longitudinal profiles also show the ...
متن کاملSerum antibiotic concentrations pre- and postcardiopulmonary bypass.
Serum concentrations of cephalothin or kanamycin, or both, were determined in 53 patients undergoing cardiopulmonary bypass. Conventional doses of these antibiotics did not provide serum levels above the accepted minimum inhibitory concentrations in children. Adults had adequate serum antibiotic concentrations only when the antimicrobials were administered within 4 h of beginning cardiopulmonar...
متن کاملHabitat compensation in nature-like fishways
STINA GUSTAFSSON H aitat om pesation in nare-like fshw ys The construction of nature-like fishways has become an increasingly common measure to restore longitudinal connectivity in streams, but these fishways also have the potential to compensate for habitat degradation and loss associated with hydropower. The habitat potential of fishways has largely been overlooked, and therefore the aim of t...
متن کاملIon Channels, Natural Nanovalves
Ion channels are proteins with holes down their middle that control the flow of ions and electric current across otherwise impermeable biological membranes. The flow of sodium, potassium, calcium (divalent), and chloride ions have been central issues in biology for more than a century. The flow of current is responsible for the signals of the nervous system that propagate over long distances (m...
