Ongoing climate warming is causing a dramatic loss of sea ice in the Arctic Ocean, and it is
projected that the Arctic Ocean will become seasonally ice-free by 2040. Many studies of …

Stable isotopes have been used extensively to study food-web functioning, that is, the flow of
energy and matter among organisms. Traditional food-web studies are based on the natural …

The temporal and spatial dynamics of primary and secondary biomass/production in the
Barents Sea since the late 1990s are examined using remote sensing data, observations …

Temperature and biodiversity changes occur in concert, but their joint effects on ecological
stability of natural food webs are unknown. Here, we assess these relationships in 19 …

Microplastic debris has become a significant global environmental issue. Yet, the effects on
ingestion of microplastics by protozoan grazers—an important link in the microbial loop—are …

We assessed the relative importance of different prey types of the European pilchard
(European sardine) from the late larval to the adult stage. Two different methodologies for …

Greenland extends from 60° to 83° N, with 80% of its land mass covered by the Greenland
Ice Sheet (GrIS). This extensive latitudinal gradient is associated with concomitant …

The Barents Sea (BS) is a high-latitude shelf ecosystem with important fisheries, high and
historically variable harvesting pressure, and ongoing high variability in climatic conditions …

Although zooplankton occupy key roles in aquatic biogeochemical cycles, little is known
about the pelagic food web and trophodynamics of zooplankton in the Red Sea. Natural …

Stable isotopes of carbon (δ 13 C) and nitrogen (δ 15 N) were used to examine trophic
structures in an arctic marine food web at small and large spatial scales. Twelve species …
