Assessment of long-distance detection of gillnets by porpoises:Reply to Dawson and Lusseau
Nielsen et al. (2012; Mar Ecol Prog Ser 453:241-248) analyzed surface observations of harbour porpoises in a small coastal area where a modified gillnet was introduced at randomized time intervals. The study concluded that porpoises reacted to the gillnet at surprisingly large distances (in some cas...
