Threat analysis

Barriers to migration – incl. damage by hydro. turbines (Winter et al. 2006, Acou et al. 2008, Azeroual

2010, van der Meer 2012)

Body condition (Boëtius and Boëtius 1980, Svedäng and Wickström 1997, van Ginneken and van den

Thillart 2000)

Climate change and/or changes in oceanic currents – including the influence of the North Atlantic

Oscillation (NAO) (Castonguay et al. 1994, Dekker 2004, Kim et al. 2004, Minegishi et al. 2005,

Bonhommeau et al. 2008, Miller et al. 2009, Durif et al. 2011, Pacariz et al. 2013)
