The concentration of n-alkanes (C 17–C 35) and sterols in marine particulate matter were
investigated to trace the origin of organic carbon in Kongsfjorden in early spring (April). The …

Explaining food web dynamics, stability, and functioning depend substantially on
understanding of feeding relations within a community. Bulk stable isotope ratios (SIRs) in …

The Barents Sea is a hotspot for environmental change due to its rapid warming, and
information on dietary preferences of zooplankton is crucial to better understand the impacts …

Stable isotope (SI) analysis is a standard tool to study marine food webs, usually based on
the measurement of a few individuals from a small list of subjectively pre-defined species …

Mesozooplankton play a crucial role as primary or secondary consumers in Arctic
ecosystems and are sensitive indicators of environmental changes. This research is the first …

Spatial variation and interspecies differences in the trophic position (TP) of copepods were
investigated using nitrogen isotope ratios of amino acids. In the summer of 2021, coastal …

Trophic position estimation has been a central issue in food web studies. Estimates using
compound‐specific isotopic analyses of amino acids were generally based on the trophic …

The zooplankton community composition in the Pacific Arctic Ocean depends heavily on the
sea ice and hydrodynamic conditions. The calanoid copepod Calanus hyperboreus is a …

Despite their crucial roles in transporting primary productions in marine food webs, the
trophic dynamics of zooplankton throughout the seasons have rarely been studied. In this …

Nemopilema nomurai is a frequently bloomed species in the China seas. Their feeding
organ has an ontogenetic change when they grow up, but whether their diet changes along …
