“…Although colonies elsewhere in the Eastern Atlantic may also be approaching or have reached their carrying capacity, it is interesting that the Orkney Islands are the sole subregion that reveals a strong signal of emigration, mostly to other sites within the Eastern Atlantic, although with weak evidence of perhaps indirect movement as far as Sable Island via colonies in southern Greenland (Rosing‐Asvid et al . ). Although not undertaking seasonal migrations such as ringed seals ( Pusa hispida ), harp seals ( Pagophilus groenlandicus ) and hooded seals ( Cystophora cristata ), long‐distance movements of individual grey seals within the Eastern Atlantic have been documented by tagging studies (Thompson et al .…”

Global population structure and demographic history of the grey seal

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 known about how the species as a whole may have historically responded to climate-driven changes in habitat availability and anthropogenic exploitation. We therefore analysed samples from over 1500 individuals collected from 22 colonies spanning the Western and Eastern Atlantic and the Baltic Sea regions, represented by 350 bp of the mitochondrial hypervariable region and up to nine microsatellites. Strong population structure was observed at both types of marker, and highly asymmetrical patterns of gene flow were also inferred, with the Orkney Islands being identified as a source of emigrants to other areas in the Eastern Atlantic. The Baltic and Eastern Atlantic regions were estimated to have diverged a little over 10 000 years ago, consistent with the last proposed isolation of the Baltic Sea. Approximate Bayesian computation also identified genetic signals consistent with postglacial population expansion across much of the species range, suggesting that grey seals are highly responsive to changes in habitat availability.

“…Indeed, the population of grey seals on the Norwegian coast and the Kola Peninsula in Russia has been increasing for the past 30 years which may trigger an expansion of their distributional range. Anecdotic records of grey seals in Greenland have been reported where individuals have been observed North up to Disko Bay and suggest that grey seals are occasional visitors to Greenlandic waters (Rosing-Asvid et al, 2010). Harbour and grey seals often haul out in similar areas and there is a permanent harbour seals population on the West coast of Svalbard (Lydersen and Kovacs, 2005;Blanchet et al, 2014).…”

Marine mammals are important players in the Barents Sea ecosystem but their structural role in the foodweb has been little explored. We compare foodweb-related characteristics within and between phylogenetic groups for 19 marine mammals. As a group, they directly connect to the most central species (i.e cod and haddock) in the Barents Sea (i.e. cod and haddock) and consume over half of the available species. Pinnipeds are the most homogenous phylogenetic group with high omnivory and high prey richness. Mysticetes are split between well-connected species with high omnivory like the humpback whale, and peripheral specialists like the blue whale. Based on foodweb-derived indices some species consistently cluster together forming two groups, suggesting topological redundancy within them. One is dominated by Arctic seals and the other includes most of the baleen whales. Marine mammals generally contribute to network modularity as their trophic links are mainly within their own module. However, Atlantic species such as the grey seal act as a module connector decreasing modularity. This might negatively affect ecosystem robustness with perturbation effects spreading further and quicker in the foodweb. In the Arctic reaches of the Barents Sea, climate warming is likely to bring about extensive changes in the foodweb structure through a redistribution of species.

“…In addition, the 19th-century Scottish explorer Robert Brown (1868) claimed to have collected a grey seal skull found near Disko Island, yet the seal skull was destroyed and its species identity could not be confirmed. The first confirmed sighting of a grey seal in Greenland occurred in 2009 when a lone grey seal was spotted near the coast of Southeast Greenland (Rosing-Asvid et al 2010). The grey seal bones at the Skraeling Island site suggest that this species may have periodically made trips further north than previously noted.…”

This paper presents the faunal material excavated from an Early Thule Inuit semi-subterranean house, house 15, from the Skraeling Island site (SfFk-4). In an effort to understand how the occupants of the house interacted with animals, a fine-grained zooarchaeological analysis is employed. Patterning in taxonomic and bone modification frequencies, skeletal element distributions, and prey demography are discussed. Inuit oral histories, mythology, and ethnographic sources are used to help interpret the results of the analysis and reconstruct the group’s subsistence economy.Cet article présente le matériel faunique provenant d’une habitation semi-souterraine datant du Thuléen ancien, l’habitation 15, située sur l’île Skraeling (SfFk-4). Afin de comprendre l’interaction entre les occupants de l’habitation et les animaux, une analyse détaillée des données zooarchéologiques a été produite. La répartition taxonomique, les fréquences des modifications des os, la répartition des éléments du squelette et la démographie des proies sont discutées. L’histoire orale inuit ainsi que les sources mythologiques et ethnographiques ont été utilisées pour contribuer à l’interprétation des résultats de l’analyse et pour reconstruire l’économie de subsistance du groupe
