Abstract The melting of the Greenland Ice Sheet is accelerating, with glaciers shifting from marine to land termination and potential consequences for fjord ecosystems downstream. Monthly samples in 2016 two fjords southwest show that subglacial discharge marine-terminating sustains high phytoplankton productivity dominated by diatoms grazed larger mesozooplankton throughout summer. In contrast...

Experiments were carried out with different Baltic Sea zooplankton taxa to scan their potential to ingest plastics. Mysid shrimps, copepods, cladocerans, rotifers, polychaete larvae and ciliates were exposed to 10 μm fluorescent polystyrene microspheres. These experiments showed ingestion of microspheres in all taxa studied. The highest percentage of individuals with ingested spheres was found ...

Environmental change strongly affects primary productivity of ecosystems via modifYing bo([om-up and top-down regulation of primary producers. Here we present a novel approach to quantifY the relative importance of regulating factors in natural systems over various time scales: we calculated daily effect sizes of major factors affecting phytoplankron , growth during the spring bloom period duri...
