Fatty acid trophic markers in the pelagic marine environment.
Lipid storage in marine zooplankton
The various functions storage lipids serve during the life history stages of zooplankton are very complex and still not fully understood and hence offer a multitude of fascinating research perspectives.
Biomass and abundance
Lipids, trophic relationships, and biodiversity in Arctic and Antarctic krill
It is concluded that T. inermis, Thysanoessa raschii, T. macrura, and E. superba have a high ratio of 18:1(n-9)/ (n-7) fatty acids, indicating animal carnivory, which is a critical factor in structuring polar marine ecosystems.

Elevated levels of 20:5(n-3) in T. libellula indicate a close connection with ice-algal production and the importance of cryo-pelagic coupling processes (i.e. exchange processes between the sea ice and the pelagic communities) for the nutrition of this high-Arctic epipelagic species.
Life histories of the copepods Pseudocalanus minutus, P. acuspes (Calanoida) and Oithona similis (Cyclopoida) in the Arctic Kongsfjorden (Svalbard)
The reproduction of the two species in Kongsfjorden seemed to be linked to phytoplankton dynamics and reproduced more or less continuously throughout the whole year with all stages occurring during the entire sampling period, suggesting two generations per year.
Lipid metabolism of the Antarctic krill Euphausia superba and its ecological implications
Abstract Various developmental stages (early larvae to adults) of Euphausia superba have been collected in different seasons in the Weddell Sea, the Lazarev Sea and off the Antarctic Peninsula to…

Mesozooplankton community structure, abundance and biomass in the central Arctic Ocean
Three different mesozooplankton communities were differentiated according to their faunistic composition and are discussed in context with the major water masses: Polar Surface Water, Atlantic Layer and Arctic Deep Water.
