They found a greater number of harp seal strandings, particularly of male yearlings, in years with low sea ice cover. The authors found no difference in genetic diversity between stranded seals and by-caught seals, which represented the healthy population; the study found overall high genetic diversity in the harp seal.

Life history theory predicts that resource competition increases as a population increases, leading to changes in life history traits such as growth, survival, and reproduction.

The Northwest Atlantic (NWA) harp seal population has increased from a low of million animals. Harp seals are a midsized phocid (true seal or earless seal) that is silver in colour, with a black face and a characteristic black pattern on the back that resembles a harp.

Harp seals occur only in the North Atlantic region. They are a migratory species that is much more wide-ranging and more pelagic than most of the other arctic seals.

They suggested that their approach was similar to that of Beddington and Williams (). Beddington, J.R. y H.A. Williams, The status and management of the Harp seal in the North-West Atlantic: a review and evaluation. Comm., (MMC/03) Benjaminsen, T., On the biology of the bottlenose whale.
