Abstract The Baltic Sea is home to a genetically isolated and morphologically distinct grey
seal population. This population has been the subject of 120‐years of careful …

Gray seals were first observed breeding in the Dutch Wadden Sea in 1985, after centuries of
absence. The breeding colony there is now the largest on the European continent. We …

A crucial first step in assessing and managing the role and impacts of predators on their
environment is knowledge on their foraging behaviour and diet. Here, we synthesize …

Growing marine mammal populations have led to renewed conflicts with fisheries and
discussions of culling as a management measure. In order to evaluate the effects of such …

The grey seal became locally extinct in the southern Baltic Sea, Danish Straits and Kattegat
in the early 1900s after prolonged culling campaigns. Here, we combine national monitoring …

The prey spectrum of grey seals has to date been described as largely consisting of different
fish, cephalopod and shrimp species. On the German island of Helgoland Düne, where …

Abstract Dietz, R., Teilmann, J., Andersen SM Rigét, F., and Olsen, MT 2013. Movements
and site fidelity of harbour seals (Phoca vitulina) in Kattegat, Denmark, with implications for …

Identifying the processes that drive changes in the abundance and distribution of natural
populations is a central theme in ecology and evolution. Many species of marine mammals …

Although the grey seal Halichoerus grypus is one of the most familiar and intensively studied
of all pinniped species, its global population structure remains to be elucidated. Little is also …

Grey (Halichoerus grypus) and harbour seals (Phoca vitulina) are sympatric seal species,
but they display distinct strategies of habitat use and connectivity between haulout sites. The …
