“…The most abundant birds with Arctic distributions are seabirds, shorebirds, and waterfowl, with other less represented species groups including passerines, grouse and birds of prey [1]. Most of these species are migratory [35] and spend the winter in more southern regions.…”

Migratory vertebrates shift migration timing and distributions in a warming Arctic

Climate warming in the Arctic has led to warmer and earlier springs, and as a result, many food resources for migratory animals become available earlier in the season, as well as become distributed further northwards. To optimally profit from these resources, migratory animals are expected to arrive earlier in the Arctic, as well as shift their own spatial distributions northwards. Here, we review literature to assess whether Arctic migratory birds and mammals already show shifts in migration timing or distribution in response to the warming climate. Distribution shifts were most prominent in marine mammals, as expected from observed northward shifts of their resources. At least for many bird species, the ability to shift distributions is likely constrained by available habitat further north. Shifts in timing have been shown in many species of terrestrial birds and ungulates, as well as for polar bears. Within species, we found strong variation in shifts in timing and distributions between populations. Ou r review thus shows that many migratory animals display shifts in migration timing and spatial distribution in reaction to a warming Arctic. Importantly, we identify large knowledge gaps especially concerning distribution shifts and timing of autumn migration, especially for marine mammals. Our understanding of how migratory animals respond to climate change appears to be mostly limited by the lack of long-term monitoring studies.

“…Each year, hundreds of species of birds migrate to the Arctic for feeding and breeding. By the end of the summer, most of which birds start to migrate to other wintering areas, spread across six continents (Fox, 2020). Our latest study found that 95% of studied birds from the arctic were carriers of ARBs and the longest migrating bird, the Arctic tern, has a signi cant role in carrying ARBs to the Arctic (Prakash et al, 2022).…”

The Arctic is losing its pristine nature due to the increased warming and human activities in the region. This may lead to the introduction of mesophilic and antibiotic-resistant bacteria (ARB) into the environment. The warming trend in the Arctic will support those bacteria to thrive in the environment. The horizontal gene exchange mechanism in the bacteria will lead to an exchange of antibiotic-resistant genes with the environmental microbes. Migratory birds have a significant role in the dissemination of pathogenic and ARB into the Arctic. In this study, the survival of pathogenic and multidrug-resistant mesophilic bacteria, E. coli isolated from migratory birds, Barnacle goose was carried out. In-situ microcosm studies were carried out in the Arctic during the summer (2017) and fall (2018) to evaluate the survival of the bacteria in the environments. In addition, this study also tested the factors such as biological, chemical, and physical parameters that determine the survival of E.coli in the Arctic waters. In the Arctic summer, the removal of the bacteria is mainly influenced by biological factors and solar radiation during summer and prolonged survival of E.coli during the fall season.
