Abstract Arctic climate change has profound impacts on the cryosphere, notably via shrinking sea‐ice cover and retreating glaciers, it is essential to evaluate forecast ecological consequences of such changes. We studied zooplankton‐feeding little auks ( Alle alle ), a key sentinel species Arctic, at their northernmost breeding site in Franz‐Josef Land (80°N), Russian Arctic. tested hypothesis that still benefit from pristine arctic environmental conditions this remote area. To end, we...
Continental slopes – steep regions between the shelf break and abyssal ocean play key roles in climatology ecology of Arctic Ocean. Here, through review synthesis, we find that narrow slope contribute to ecosystem functioning disproportionately size habitat area (∼6% total Ocean area). Driven by inflows sub-Arctic waters steered topography, boundary currents transport boreal properties particle loads from Atlantic Pacific Oceans along-slope, thus creating both along cross-slope connectivity...
Plastic pollution has been reported to affect Arctic mammals and birds. There are strengths limitations monitoring litter microplastics using One strength is the direct use of these data understand potential impacts on biodiversity as well effects human health, if selected species consumed. Monitoring programs must be practically designed with all purposes in mind, a spectrum approaches will required. Spatial temporal trends plastic can built information obtained from studies northern...
Marine plastic is a ubiquitous environmental problem that can have an impact on variety of marine biota, such as seabirds, making it important concern for scientists and policy makers. Although research ingestion by seabirds increasing, few studies examined policies long-term monitoring programs to reduce in the Arctic. This paper provides review international, national, regional address relation Arctic countries: Canada, Kingdom Denmark (Greenland Faroe Islands), Finland, Iceland, Norway,...
We found high levels of contaminants, in particular organochlorines, eggs the ivory gull Pagophila eburnea, a Arctic seabird species threatened by climate change and contaminants. An 80% decline breeding population Canadian last two decades has been documented. Because dependence on sea ice its trophic position, suggested environmental threats are The present study investigated contaminant (organochlorines, brominated flame retardants, perfluorinated alkyl substances, mercury) from four...
The post‐breeding movements of three northeast Atlantic populations (north Greenland, Svalbard and Franz Josef Land) the ivory gull Pagophila eburnea , a threatened high‐Arctic sea‐ice specialist, were studied between July December 2007 using 31 satellite transmitters. After leaving their breeding grounds, all birds first dispersed eastward in August–September, to an area extending from Fram Strait northwestern Laptev Sea (off Severnaya Zemlya). Most returned along same flyway...
Abstract The emperor penguin ( Aptenodytes forsteri ) is highly dependent on sea ice conditions, and future climate change may affect its distribution numbers. Most studies the demography population dynamics of penguins in relation to characteristics were conducted at a single colony (Pointe Géologie). Several non-exclusive hypotheses have been proposed explain dramatic decline this colony, including changes predation, flipper banding human disturbance. Here, we report analyse updated...
Cryophilic algae thrive in liquid water within snow and ice alpine polar regions worldwide. Blooms of these lower albedo (reflection sunlight), thereby altering melting patterns (Kohshima, Seko & Yoshimura, 1993; Lutz et al., 2014; Thomas Duval, 1995). Here metagenomic DNA analysis satellite imaging were used to investigate red Franz Josef Land the Russian Arctic. metagenomes confirmed that communities are composed autotroph Chlamydomonas nivalis is supporting a complex viral...
Despite the limited direct anthropogenic mercury (Hg) inputs in circumpolar Arctic, elevated concentrations of methylmercury (MeHg) are accumulated Arctic marine biota. However, MeHg production and bioaccumulation pathways these ecosystems have not been completely unraveled. We measured Hg stable isotope ratios Hg, carbon, nitrogen feathers blood geolocator-tracked little auk Alle alle from five breeding colonies. The wide-range spatial mobility tissue-specific integration times this...
Bird migration is commonly defined as a seasonal movement between breeding and non-breeding grounds. It generally involves relatively straight directed large-scale movements, with latitudinal change, specific daily activity patterns comprising less or no foraging more traveling time. Our main objective was to describe how this general definition applies seabirds. We investigated characteristics of 6 pelagic seabird species (little auk Alle alle , Atlantic puffin Fratercula arctica common...
Mercury (Hg) is a heterogeneously distributed toxicant affecting wildlife and human health. Yet, the spatial distribution of Hg remains poorly documented, especially in food webs, even though this knowledge essential to assess large-scale risk toxicity for biota populations. Here, we used seabirds assess, at an unprecedented population geographic magnitude high resolution, North Atlantic marine webs. To end, combined tracking data 837 from seven different species 27 breeding colonies located...
Quantifying patterns of genetic diversity and differentiation among populations Arctic birds is fundamental for understanding past ongoing population processes in the Arctic. However, many important species remains uninvestigated. Here, phylogeography genetics were examined worldwide a small seabird, little auk (dovekie, Alle alle)—the most numerous avian ecosystem. Blood samples or feathers collected from 328 auks (325 nominate subspecies 3 A. a. polaris) nine main breeding aggregations...
Abstract The ivory gull Pagophila eburnea is a high‐Arctic species threatened by climate change and contaminants. objective of the present study was to assess spatial variation contaminant levels (organochlorines [OCs], brominated flame retardants [BFRs], perfluorinated alkyl substances [PFASs], mercury [Hg]) in gulls breeding different areas across Arctic region as baseline for potential future changes associated with change. Contaminants were already determined eggs from Canada (Seymour...
We examined diatom assemblages from 18 stream and pond samples in the Franz Josef Land Archipelago (FJL), most northern land of Eurasia. More than 216 taxa were observed, revealing a rich circumpolar flora, including many undescribed taxa. Widely distributed abundant by cell densities, while species rich. Stream habitats hosted different assemblages, varied along pH gradient. Diatoma tenuis was ubiquitous taxon. However, several such as Chamaepinnularia gandrupii, Cymbella botellus,...
The ongoing decline of sea ice threatens many Arctic taxa, including the ivory gull. Understanding how ice-edges and concentrations influence distribution endangered gulls is a prerequisite to implementation adequate conservation strategies. From 2007 2013, we used satellite transmitters monitor movements 104 originating from Canada, Greenland, Svalbard-Norway Russia. Although half positions were within 41 km ice-edge (75% 100 km), approximately 80% on relatively highly concentrated ice....
Abstract Forestalling the decline of global biodiversity requires urgent and transformative action at all levels government society, particularly in Arctic Ocean adjacent seas where rapid changes are already underway. Amid growing scientific support mounting pressure, majority nations have committed to most ambitious conservation targets yet. However, without an approach that inclusively equitably reconciles sustainable ocean use, these will likely go unmet. Here, we present ArcNet: a...

Tracking data of marine predators are increasingly used in spatial management. We developed a set with estimates the monthly distribution 6 pelagic seabird species breeding Northeast Atlantic. The was based on year-round global location sensor (GLS) tracking 2356 adult seabirds from 2006-2019 network colonies, describing physical environment and population sizes. environmental were combined models (SDMs). Cross-validations to assess transferability between years locations. analyses showed...
Life under the earth surface is highly challenging and associated with a number of morphological, physiological behavioral modifications. Subterranean niche protects animals from predators, fluctuations in environmental parameters, but characterized by high levels carbon dioxide low oxygen implies energy requirements burrowing. Moreover, it lacks most sensory inputs available above ground. The current study describes results RNA-seq analysis four subterranean voles subfamily Arvicolinae:...
