Drivers of the small-scale spatio-temporal distribution of harbour porpoises (Phocoena phocoena) investigated via UAV around Kullaberg, Sweden
The harbour porpoise (Phocoena phocoena) is elusive and challenging to study. Recent reports indicate negative population trends in the Belt Sea population, which is found around the peninsula of Kullaberg in southern Sweden. In this study, the driving factors of the small-scale distribution of porpoises around Kullaberg were investigated by use of an unmanned aerial vehicle (UAV). Over 17 weeks f
