Abstract High Arctic ecosystems and Indigenous livelihoods are tightly linked exposed to climate change, yet assessing their sensitivity requires a long-term perspective. Here, we assess the vulnerability of North Water polynya, unique seaice ecosystem that sustains world’s northernmost Inuit communities several keystone species. We reconstruct mid-to-late Holocene changes in sea ice, marine primary production, little auk colony dynamics through multi-proxy analysis lake sediment cores. Our...
In some arctic areas, marine-derived nutrients (MDN) resulting from fish migrations fuel freshwater and terrestrial ecosystems, increasing primary production biodiversity. Less is known, however, about the role of seabird-MDN in shaping ecosystems. Here, we examine how most abundant seabird North Atlantic, little auk (Alle alle), alters ecosystems around Water Polynya (NOW) Greenland. We compare stable isotope ratios (δ15N δ13C) biota, vegetation indices physical-chemical properties,...
Abstract Aim Extensive development of human activities in combination with ocean warming is rapidly modifying marine habitats the A rctic and N orth tlantic regions. To understand potential impacts on biodiversity, there an urgent need to determine distributions habitat preferences potentially vulnerable species identify sensitive hotspots that might require particular protection. Our aims were track one most abundant seabirds world, little auk ( lle alle ), provide a large, meta‐population...
The little auk is the most numerous seabird in North Atlantic and its important breeding area eastern shores of Water polynya. Here, a population an estimated 33 million pairs breeds huge colonies significantly shapes ecosystem. Archaeological remains document that has been harvested over millennia. Anthropological research discloses how role both as social engineer significant resource for Inughuit today. hunting can be practiced without costly equipment, no gender age discrimination...
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...
Considering seabirds as indicators of environmental change, we compared thick-billed murre ( Uria lomvia (Linnaeus, 1758)) adult and chick diet in the North Water polynya region, NW Greenland, during 1997 2023. In diet, fish accounted for 86% 42% food items by number, 99% wet mass (WM) both Arctic cod Boreogadus saida (Lepechin, 1774)) was most important prey, contributing 90% WM 2023, respectively. murres ate mostly small 1-year-old but 2023 they mainly took larger 2- 3-year-old cod. gadids...
The North Water (NOW) polynya is one of the most productive marine areas Arctic and an important breeding area for millions seabirds. There is, however, little information on dynamics or bird populations over long term. Here, we used sediment archives from a lake peat deposits along Greenland coast NOW to track long-term patterns in seabird populations. Radiocarbon dates show that thick-billed murre (Uria lomvia) common eider (Somateria mollissima) have been present at least 5500 cal. years....
Information from a collaborative GPS tracking project, Piniariarneq, involving 17 occupational hunters Qaanaaq and Savissivik, Northwest Greenland, is used to explore the resource spaces of in Avanersuaq today. By comparison with historical records time Thule Trading Station decades following its closure, we reveal marked variability over time. It argued that dynamics resources are not underlain by animal distribution migration patterns, or changes weather sea ice conditions alone; but also...
1. Oxygen uptakes from air and water have been measured in relation to weight of the African lungfish Protopterus amphibius Peters. 2. Combined O2 uptake ranged 60 ml kg-1 h-1 STPD, a 3-7 g specimen, 30 O2kg-1 h-1, 255 specimen. 3. While combined changed by factor 2, within range under study, aquatic 8-fold same range. The smaller fish satisfy 70% their requirement breathing compared 10-15% grown specimens. 4. pattern bimodal P. is discussed natural habitat species.

Development of new methods for obtaining basic demographic data from difficult-to-access breeding colonies and easily disturbed species is an important challenge in studies seabirds. We describe a method that can generate concerning annual success cliff-nesting seabirds or other colonial birds with open nests. Our requires only single visit to colony every second third year, based on the use automated time-lapse photography. To test our method, we used photos examine Thick-billed Murres...
Abstract We explored the implications of reaching Paris Agreement Objective limiting global warming to <2°C for future winter distribution North Atlantic seabird community. predicted and quantified current habitats five Ocean species ( Alle alle , Fratercula arctica Uria aalge lomvia Rissa tridactyla ) using tracking data ~1500 individuals through resource selection functions based on mechanistic modeling energy requirements, a dynamic bioclimate envelope model prey.

Abstract This contribution is a critical survey and discussion of patterns settlement land use at the Mesolithic-Neolithic transition in Southern Scandinavia. The Ertebolle Culture (EBK) earliest stage Funnel Beaker Culture, early Neolithic I (EN I), are thoroughly examined, leading to comparison between two periods. It found that our view on system EBK needs revision. In recent years, has been characterised according model complex hunters. Large groups live sedentary life big year-round...
The Environment & Oil Spill Response tool (EOS), supports oil spill response planning and decision making. This is developed on a research basis, an index based, generic open-source analytic tool, which environmentally can optimise the choice of methods for given situation sea area with respect to environment nature. not linked particular simulation model, although it recommended using models have detailed data available analysis.

Summary Ritenbenk/Innaq in Disko Bay is the only remaining Thick-billed Murre colony central West Greenland. It has declined by 72% since 1980 and now (2012) holds c.1,100 breeding pairs. In 2005–2006 2011–2012, a number of studies were carried out this to improve our understanding population decline its causes. Hunting previously been identified as problem for colony, but local conditions have never studied non-breeding distribution was known from ringing. Our showed that success moderate...
The South-west Greenland Open Water Area is an internationally important wintering area for seabirds in the North Atlantic. Nearly two decades after was last surveyed, we conducted a replicate aerial survey March 2017 to update information on distribution and abundance of seabirds. With total effort about 5800 km, covered coastal from Aasiaat (69°N) Kap Farvel (60°N), 56% open water fjords, offshore bank, Store Hellefiskebanke. Line transect methodology used except which were censused by...
