There is little doubt that Arctic ecosystems will continue to face unprecedented change in the coming decades. The identification of food web structures that confer stability to these systems is, therefore, a priority. Here, we use stable isotopes and fatty acids to resolve the food web structure of a seasonally ice-covered fjord (Cumberland Sound, Baffin Island, Canada) sampled in late summer. We show that the food web is structured such that upper trophic levels couple separate energy…

Food-Web Structure in Four Locations Along the European Shelf Indicates Spatial Differences in Ecosystem Functioning

Studies of trophic interactions give valuable insights into the functioning of ecosystems and can be used to identify qualitative differences among ecosystems. Here, we use natural stable isotope

Deciphering the structure of the West Greenland marine food web using stable isotopes (δ13C, δ15N)

The Arctic is facing major environmental changes impacting marine biodiversity and ecosystem functioning. One way of assessing the responses of an ecosystem to these changes is to quantitatively

Deciphering the structure of the West Greenland marine food web using stable isotopes (δ13C, δ15N)

Stable isotope analyses of 39 Arctic marine species to investigate trophic relationships and isotopic niches of the West Greenland food web in 2000–2004 provide new insights into species and functional group interactions, as well as into the food web structure and ecosystem functioning of an important Arctic region that can be used as a template to guide future modelling of carbon, energy and contaminant flow in the region.

Climate change and diminishing seasonality in Arctic benthic processes

Seasonality in benthic biogeochemical cycling at three stations in a high Arctic fjord that has recently lost much of its seasonal ice-cover is investigated, finding little seasonality in sediment community respiration and bioturbation rates, although different sediment reworking modes varied through the year.

Horizontal and vertical food web structure drives trace element trophic transfer in Terra

14 Despite in the last decades a vast amount of literature has focused on trace element (TE) 15 contamination in Antarctica, the assessment of the main pathways driving TE transfer to the biota 16 is



Benthic food-web structure of an Arctic fjord (Kongsfjorden, Svalbard)

Findings confirmed findings from other areas indicating that Arctic food chains are long, consisting of between 4 and 5 trophic levels, and suggested relatively little variability in food-web structure over the temporal and spatial scales studied.

Kelp as a trophic resource for marine suspension feeders: a review of isotope-based evidence

The evidence showing that phytoplankton isotope values can, and are expected to, vary widely in coastal waters and that inshore phy toplankon may often be enriched in 13C compared to offshore phy Topolankton is reviewed, which may have systematically biased the results of trophic studies toward finding large contributions of kelp detritus to suspension-feeder diets.

Energy Flow through the Marine Ecosystem of the Lancaster Sound Region, Arctic Canada

This paper synthesizes the trophic dynamics of a Canadian arctic marine ecosystem in so far as it is known, using new data on primary production, zooplankton, the bivalve Mya truncata , and arctic

Trophic relationships and pelagic-benthic coupling during summer in the Barents Sea Marginal Ice Zone, revealed by stable carbon and nitrogen isotope measurements

Food web structure and pathways from primary production were studied in pelagic, sympagic (ice-associated) and benthic communities during summer in a seasonally ice covered region of the northern

General Ecology of the Canadian Arctic Benthic Marine Algae

The Canadian Arctic marine flora is basically a regional extension of Atlantic species. As the extreme environmental conditions of low temperature, low salinity and long periods of darkness intensify
