It is well known that tropical oceans harbour a rich biodiversity of calanoid copepods.
However, their functional traits, ecophysiological adaptations and life strategies have hardly …

The northern Humboldt Current upwelling system (HCS) belongs to the most productive
marine ecosystems, providing five to eight times higher fisheries landings per unit area than …

Knowing the migratory movements and behaviour of baleen whales is fundamental to
understanding their ecology. We compared δ15N and δ13C values in the skin of blue …

Lanternfishes (Myctophidae) constitute the most important component of the daily vertically
migrating mesopelagic fish community. This research addresses the estimation of the trophic …

Zooplankton are important consumers of sinking particles in the ocean's twilight zone.
However, the impact of different taxa depends on their feeding mode. In contrast to typical …

Southern hemisphere humpback whales are classified as high-fidelity Antarctic krill
consumers and as such are vulnerable to variability and long-term changes in krill biomass …

Recent studies suggest that the global biomass of fish in the ocean is dominated by meso-
and bathypelagic fish. However, despite their abundance and important role in marine …

The importance of microbes for the functioning of oceanic food webs is well established, but
their relevance for top consumers is still poorly appreciated. Large differences in individual …

We used linear inverse ecosystem modeling techniques to assimilate data from extensive
Lagrangian field experiments into a mass-balance constrained food web for the Gulf of …

Small copepod genera play an important role in marine food webs and biogeochemical
fluxes but have been neglected in many studies. This is the first study determining biomass …
