The commercial importance of Pacific and Atlantic herring (Clupea pallasii and Clupea harengus) has ensured that much of their biology has received attention. However, their sound production remains poorly studied. We describe the sounds made by captive wild-caught herring. Pacific herring produce distinctive bursts of pulses, termed Fast Repetitive Tick (FRT) sounds. These trains of broadband ...

OBJECTIVE To make an useful identification method for the molecule of DNA on 3 herbs of Artemisia genus and compare the differences of the genes of Korean and Chinese species of Artemisia. METHODS Sequence of 3 herbs (Artemisia sacrorum Ledeb., Artemisia iwayomogi Kitam. and Artemisia capillaris Thunb.) was determined by PCR sequence system. DNA was extracted from rDNA/ITS (internal transcrib...
