From: Predation of archival tagged Dolly Varden, Salvelinus malma, reveals predator avoidance behaviour and tracks feeding events by presumed beluga whale, Delphinapterus leucas, in the Beaufort Sea

Fig. 1

Map of study area in the eastern Beaufort Sea illustrating the location where an anadromous Dolly Varden was satellite archival tagged in September, 2019, the area where the tagged fish was presumably eaten by a beluga whale on July 7, 2020, the location where the tag was presumably regurgitated by the beluga whale, and the location where the tag reported to satellites on July 15, 2020. Locations are shown where beluga whales were satellite archival tagged in summer 2018 and 2019, and whose depth and spatial habitat use were assessed in the Dolly Varden spatial polygon (delineated based on previously satellite archival tagged Dolly Varden from Canadian populations (Big Fish R. and Rat R.) that reported in mid-July in the Beaufort Sea (2015–2018)). Sea surface temperatures (SST) (average between July 3 and 10, 2020) and sea-ice conditions (July 8, 2020) of the Beaufort Sea near the approximate date of predation are shown along with the start locations of the detailed dive profiles illustrated in Fig. 4 from tagged belugas within the spatial polygon
