Migrations are often influenced by seasonal environmental gradients that are increasingly being altered by climate change. The consequences of rapid changes in Arctic sea ice have the potential to affect migrations of a number of marine species whose timing is temporally matched to seasonal sea ice cover. This topic has not been investigated for Pacific Arctic beluga whales (Delphinapterus leucas) that follow matrilineally maintained autumn migrations in the waters around Alaska and Russia. For… 

Annual variation of oceanographic conditions changed migration timing of bowhead whales Balaena mysticetus in the southern Chukchi Sea

The Chukchi Sea environment changes considerably in physical and biological conditions, driven by the expanding volume of warm Pacific summer water. These environmental changes can affect the

Seasonal patterns in acoustic detections of marine mammals near Sachs Harbour, Northwest Territories1

The Arctic is changing rapidly, leading to changes in habitat availability and increased anthropogenic disturbance. Information on the distribution of animals is needed as these changes occur. We

Interannual variability in acoustic detection of blue and fin whale calls in the Northeast Atlantic High Arctic between 2008 and 2018

Northern Hemisphere blue and fin whales are regular summer migrants to Arctic waters. Given the profound changes the Arctic is currently undergoing due to global warming, changes in habitat use and

Decadal migration phenology of a long-lived Arctic icon keeps pace with climate change.

Animals migrate in response to seasonal environments, to reproduce, to benefit from resource pulses, or to avoid fluctuating hazards. Although climate change is predicted to modify migration, only a

Timing is everything: Drivers of interannual variability in blue whale migration

The correlation between krill abundance and the transition from D to B calls suggested that in high-krill-abundance years, whales switched earlier from social to reproductive-related behavior on their feeding grounds, which may allow blue whales to accommodate environmental variability while balancing important biological needs.

Decadal‐scale phenology and seasonal climate drivers of migratory baleen whales in a rapidly warming marine ecosystem

Species' response to rapid climate change can be measured through shifts in timing of recurring biological events, known as phenology. The Gulf of Maine is one of the most rapidly warming regions of

Migration dynamics of polar bears (Ursus maritimus) in western Hudson Bay

It was found that ice concentration, wind speed, and wind direction affected polar bear migration onto ice during freeze-up and ice concentration and wind Direction affected migration onto land during breakup.

Circumpolar phylogeography and demographic history of beluga whales reflect past climatic fluctuations

The association between climate, population size, and available habitat in belugas is suggested, and vulnerable populations which, if extirpated as a consequence of ocean warming, will lead to a substantial decline of species‐wide haplotype diversity are identified.

Habitat selection by two beluga whale populations in the Chukchi and Beaufort seas

The results indicate that sea ice variables were rarely the primary drivers of beluga summer-fall habitat selection, and associations with bathymetric features that affect prey availability seemed key to habitat selection during summer and fall.

An examination of seasonal occurrence, foraging plasticity and (for bowhead whales) body condition suggests that the current state of Pacific Arctic marine ecosystem may be ‘boom times’ for baleen whales.

Increased Land Use by Chukchi Sea Polar Bears in Relation to Changing Sea Ice Conditions

Comparing land use patterns in the Chukchi Sea between two periods when substantial summer sea-ice loss occurred suggests that the ecology of this region may provide a degree of resilience to sea ice loss, and is consistent with other studies supporting increased land use as a common response of polar bears to sea- ice loss.
