areas of West Greenland in October–November and remain in the area through April. They spend the summer in the Cana-dian high Arctic around Somerset Island (Innes et al., 2002; Fig. 1). Only one segment of the beluga aggregation near Som-erset Island moves to West Greenland in the winter (Heide-Jørgensen et al., 2003).
Rebuilding beluga stocks in West Greenland Heide
2016-11-11 · Only one segment of the beluga aggregation near Somerset Island moves to West Greenland in the winter (Heide‐Jørgensen et al., 2003). The rest winters in the North Water region in northern Baffin Bay (Heide‐Jørgensen et al ., 2016 ) and therefore abundance estimates from Somerset Island (e.g. Innes et al ., 2002 ) are not directly

Fig.1 The territory of Greenland is panelized into 28 mascons, which are aggregated into five drainage systems. In addition, 9 mascons outside Greenland are defined to account for possible mass variations there. Red stars denote the glaciers considered in the estimation of
An important late summer aggregation of fin whales
2014-8-7 · The distribution at sea of upper trophic levels—seabirds and marine mammals—is depending on their food availability: high concentrations reflect high prey abundance and thus high biological production. Polar marine ecosystems are characterized by low biodiversity and high biological patchiness. The distribution of predators, as a consequence, shows a similar patchiness. During two

Suppose that individual correlations, estimated during the first stage of the analysis, were found to be statistically significant. The same (or similar) relationships are likely to emerge under the aggregation scheme featured in Fig. 1a. According to this scheme, the aver-
