Atlantic water influx and sea-ice cover drive taxonomic and functional shifts in Arctic marine bacterial communities
The Arctic Ocean is experiencing unprecedented changes because of climate warming, necessitating detailed analyses on the ecology and dynamics of...
-
Salinity-controlled distribution of prokaryotic communities in the Arctic sea-ice melt ponds
The thawing of snow and sea ice produces distinctive melt ponds on the surface of the Arctic sea ice, which covers a significant portion of the...

Contrasting sea ice conditions shape microbial food webs in Hudson Bay (Canadian Arctic)
The transition from ice-covered to open water is a recurring feature of the Arctic and sub-Arctic, but microbial diversity and cascading effects on...

Behavior of Arctic fourhorn sculpin (Myoxocephalus quadricornis) beneath winter sea ice assessed with passive acoustic telemetry in Tremblay Sound (Baffin Island, Canada)
The Arctic experiences dramatic annual cycles in environmental condition, including winters that can last two thirds of the year. During these long...

Influence of sea-ice-related features and anthropogenic subsidies on the foraging behaviour of a high-Arctic seabird, the ivory gull (Pagophila eburnea)
The Arctic region is currently experiencing major modifications in sea ice extent and phenology due to global climate and anthropogenic changes. As...

Arctic bacterial diversity and connectivity in the coastal margin of the Last Ice Area
Arctic climate change is leading to sea-ice attrition in the Last Ice Area along the northern coast of Canada and Greenland, but less attention has...
-
First trait-based characterization of Arctic ice meiofauna taxa
Trait-based approaches connect the traits of species to ecosystem functions to estimate the functional diversity of communities and how they may...
-
Nitrogen and sulfur metabolisms encoded in prokaryotic communities associated with sea ice algae
Sea ice habitats harbour seasonally abundant microalgal communities, which can be highly productive in the spring when the availability of light...

Sea ice directs changes in bowhead whale phenology through the Bering Strait
BackgroundClimate change is warming the Arctic faster than the rest of the planet. Shifts in whale migration timing have been linked to climate...

Sea ice presence is linked to higher carbon export and vertical microbial connectivity in the Eurasian Arctic Ocean
Arctic Ocean sea ice cover is shrinking due to warming. Long-term sediment trap data shows higher export efficiency of particulate organic carbon in...

Sea ice extent and phenology influence breeding of high-Arctic seabirds: 4 decades of monitoring in Nunavut, Canada
Seabirds breeding in the high Arctic contend with variable annual sea ice conditions, with important consequences depending on a species’ unique...

Water Mass Controlled Vertical Stratification of Bacterial and Archaeal Communities in the Western Arctic Ocean During Summer Sea-Ice Melting
The environmental variations and their interactions with the biosphere are vital in the Arctic Ocean during the summer sea-ice melting period in the...

Diversity of heterotrophic picoeukaryotes in the ice of the Kandalaksha Gulf (White Sea, Russia) based on rRNA gene high-throughput sequencing
Contemporary climate change in the Arctic is causing the reduction of the ice habitat. This process induces rearrangements in the community...

Armored fish in cold polar waters: New information on the Arctic alligatorfish Aspidophoroides olrikii (Agonidae, Perciformes, Teleostei) from the Kara Sea (Siberian Arctic)
Data on the spatial and vertical distributions, temperature regime of habitat, size-age and, size-sex structure of Arctic alligatorfish Aspidophoroides...

Reduced seasonal sea ice and increased sea surface temperature change prey and foraging behaviour in an ice-obligate Arctic seabird, Mandt’s black guillemot (Cepphus grylle mandtii)
While decreases in Arctic sea ice affect all marine communities in the Arctic Basin, the effects are greatest on the cryopelagic ecosystem and...

Morphological and genetic diversity of ice-associated nematodes of the family Xyalidae Chitwood, 1951
The ice-associated nematode Theristus melnikovi has a long-distance dispersal throughout the Arctic. However, this species’ taxonomic position and...

Migration timing and marine space use of an anadromous Arctic fish (Arctic Char, Salvelinus alpinus) revealed by local spatial statistics and network analysis
BackgroundThe ice-free season (typically late-June to early-October) is crucial for anadromous species of fish in the Arctic, including Arctic Char (

Eastward journey: a second capture and first genetically confirmed record of Greenland shark Somniosus microcephalus in the Laptev Sea (Siberian Arctic)
The Greenland shark Somniosus microcephalus is the most northern and cold-water shark, longest-lived vertebrate, and species at risk. A single...
