Cascading effects of the ctenophore Mnemiopsis leidyi on the planktonic food web in a nutrient-limited estuarine system
(Journal article; Peer reviewed, 2012-07-24)Increasing biomasses of gelatinous zooplankton presumably have major implications for the structure and function of marine food webs at large; however, current data on lower trophic levels are scarce, as most studies ... -
In situ swimming speed and swimming behaviour of fish feeding on the krill Meganyctiphanes norvegica
(Journal article; Peer reviewed, 2005)In situ swimming speed and swimming behaviour of dielly migrating planktivorous fish were studied at a 120-m-deep location. Acoustic target tracking was performed using a hull-mounted transducer and submersible ... -
Seasonal plankton dynamics along a cross-shelf gradient
(Journal article; Peer reviewed, 2006-08-08)Much interest has recently been devoted to reconstructing the dynamic structure of ecological systems on the basis of time-series data. Using 10 years of monthly data on phyto- and zooplankton abundance from the Bay of ... -
Spatial variability of the plankton trophic interaction in the North Sea: a new feature after the early 1970s
(Journal article; Peer reviewed, 2011-08-24)Traditionally, marine ecosystem structure was thought to be bottom-up controlled. In recent years, a number of studies have highlighted the importance of top-down regulation. Evidence is accumulating that the type of trophic ... -
Turbulence-induced contact rates in plankton: the issue of scales
(Journal article; Peer reviewed, 1996-08-29)
