claimThere is currently no information on temporal changes in migration for marine fish, as most data comes from annual trawling which reveals distribution changes over time rather than migration timing, according to Fossheim et al. (2015), Frainer et al. (2017), and Levine et al. (2023).
claimFor capital migrants, the timing of movements is critical and depends on the availability of food and suitable environmental conditions immediately upon arrival at their destination.
claimGlobal warming has induced variability in the timing of migration for many marine mammal species, including Arctic endemics.
claimDuring the post-breeding period, seabirds in the eastern Chukchi Sea must replenish body reserves and prepare for winter and migrations south.
referenceA. R. Szesciorka, K. M. Stafford, and C. L. Berchok documented a basin-wide shift in bowhead whale migration in the Pacific Arctic in a 2024 study published in Geophysical Research Letters.

claimIncreased water temperatures and higher productivity are associated with the increasingly northward extent of migration in Subarctic and temperate species, such as Pacific salmon.
referenceFrederiksen, M., Descamps, S., Erikstad, K. E., Gaston, A. J., Gilchrist, H. G., Grémillet, D., et al. (2016) published 'Migration and wintering of a declining seabird, the thick-billed murre Uria lomvia, on an ocean basin scale: conservation implications' in Biological Conservation, volume 200, pages 26–35, investigating the migration and wintering patterns of the thick-billed murre.
claimSome species may benefit from climate change by gaining access to more direct migration routes and higher-quality food over a longer season, which reduces individual energetic expenditures.
claimInterannual variability in spatial distribution during migration is common for species such as short-tailed shearwaters, black-legged kittiwakes, and red phalaropes.
claimIncome migrants forage while moving toward their migration endpoint, rely on multiple ecosystems for replenishment, and undergo little or no physiological preparation for migration.
referenceThick-billed murres in breeding pairs migrate and overwinter in locations far apart from each other but within similar photic environments, according to a 2024 study by Huffeldt et al.
claimAnadromous and marine fishes, certain marine mammals, and at least three species of seabirds exhibit resident migration patterns within Subarctic or Arctic areas.
referenceThe article titled 'A review of climate change impacts on migration patterns of marine vertebrates in Arctic and Subarctic ecosystems' was published in the journal Frontiers in Environmental Science on October 25, 2024.
claimArctic resident fish species typically perform limited migrations within Arctic waters, moving between spawning, feeding, and overwintering areas.
referenceClimate warming and the reduction of the Bering Sea “Cold Pool” thermal barrier (bottom water approximately −1.5°C) could facilitate increased migration of skates and other fishes from the Bering Sea through the Bering Strait into the Arctic Ocean, according to Mueter et al. (2021).
claimThe ivory gull faces a high risk of population decline and potential extinction before the end of the century due to changes in the ice habitat used for migration and overwintering, combined with the impact of receding summer sea ice near breeding colonies.
claimThe forms of migration vary widely within and among animal taxa.
claimClimate change-induced impacts on migration can affect reproductive success and overwintering survival, with repercussions for entire populations, as noted by Harrison et al. (2011).
claimUnpredictability in Arctic physical and biological conditions poses a significant challenge for marine vertebrates that rely on migration for survival and reproductive success.
claimAnimals that are restricted to specific habitats during migration or are limited to small movement areas face greater impacts from climate-driven habitat alterations.
claimThere is a lack of comprehensive data regarding the extent to which seabirds rely on cross-Arctic routes for migration between breeding and overwintering areas, though satellite tracking and radar studies have confirmed that such routes exist.
claimNon-breeding migrants arrive in the Arctic during summer and fall specifically to feed.
claimCapital migrants must store adequate energy reserves for their entire journey and often undergo physiological alterations to conserve energy until they reach their migration endpoint.
claimResearch on how climate change affects migration has focused more on Atlantic salmon (Salmo salar), Arctic char (Salvelinus alpinus), and brown trout (Salmo trutta) compared to coregonines and endemic populations of Pacific salmon north of the Bering Strait.
procedureThe review of Arctic marine ecology regarding migration covers fishes, seabirds, and marine mammals, utilizing sources from scientific journals, books, and agency reports identified via Google Scholar and Web of Science.
claimHooded seal populations have shifted the phenology of their migration by leaving breeding areas earlier and have shifted their migratory endpoints farther north to maintain access to their preferred oceanographic characteristics.
claimAnimals must synchronize the timing of their movements with food resource availability, a requirement that is particularly critical for species migrating to the Arctic to breed.
claimFish species that perform multiple lifetime migrations are particularly vulnerable to climate change because they must repeatedly time their migrations to match pulses of marine production during spring and summer.
Climate Change & Its Impact on Migration and Breeding Cycles husson.edu Aug 20, 2025 6 facts
claimArctic caribou are delaying migration and experiencing increased stress from insect swarms and unpredictable conditions due to climate change.
claimWarming waters and changing seasonal habitats in the Arctic and Subarctic are altering migration and breeding patterns for fish, seabirds, and marine mammals.
claimWarming ocean waters have caused marine species to alter their migration routes and feeding patterns.
claimArctic caribou face migration disruptions because thawing ice makes river crossings more dangerous and warmer weather increases insect harassment along their traditional routes.
claimPied flycatchers migrate based on fixed triggers like day length, but often arrive at breeding grounds after food sources have already peaked, which negatively impacts their survival and reproduction.
claimGlobal temperature increases are causing significant shifts in species migration, disruptions in breeding cycles, and changes in long-established animal behaviors.
