Spatial distribution and foraging behaviour of Harbour Seals (Phoca vitulina) in the Wadden Sea

Movement and habitat use are essential population processes fundamental for the management and conservation of animal species. Hence, the ability to track and infer specific animal behaviours are problems that have concerned scientists for many years. Technological advances have contributed to the i...
