Pup mortality in a rapidly declining harbour seal (Phoca vitulina) population. [PDF]
PLoS ONE, 2013 The harbour seal population in Orkney, off the north coast of Scotland, has reduced by 65% between 2001 and 2010. The cause(s) of this decline are unknown but must affect the demographic parameters of the population.

Female harbor seal (Phoca vitulina) behavioral response to playbacks of underwater male acoustic advertisement displays [PDF]
PeerJ, 2018 During the breeding season, male harbor seals (Phoca vitulina) make underwater acoustic displays using vocalizations known as roars. These roars have been shown to function in territory establishment in some breeding areas and have been hypothesized to ...
