The authors note that reservoir construction often leads to many-fold increases in the area of standing water in a region and that reservoirs typically replace varied stream habitats with habitats more similar t...

This emergence and rapid distribution of FL, despite the vaccination program that was started in September 2005, also suggests that the current H5N1 control measures are still inadequate, Webster said. Moreover,...
