Om Peter Tiselius

Professor in marine zooplankton ecology. I work on predator prey-interactions in plankton, physical-biological coupling and food web dynamics in the pelagic environment.
Research interests

My overall research interests are:
Predatory control in marine pelagic ecosystems and the role of zooplankton as transformers of organic material
Marine pelagic food webs are characterised by more predators on each prey type and more prey types for each predator than limnetic communities. Controlling factors are harder to define and the trophic cascade typical of lakes are rarely found in the sea. A key group in the trophic transfer is the zooplanktivores. Each species target specific prey and the details of the encounter are necessary to account for when modelling the trophic transfer. Since the quality of the consumers is highly dependent on the primary production which in turn varies with hydrographic regime, the functioning of the zooplanktivores are likely very dynamic. The biodiversity of the plankton is therefore a key factor.
My main research interest is the dynamics of plankton interactions, both in terms of behaviour and in trophic role. All trophic transformations in plankton have wide ranging implications for fish and the role of fatty acid dynamics is a recent object of my research. In my laboratory there are several collaborators that work on different aspects of predation and we complement each other in competence.
Ongoing projects

• High speed filming of food capture in copepods
• Trophic cascades in coastal zooplankton communities
• Carbon and nitrogen fluxes associated with large cyanobacteria of the Baltic Sea - small-scale processes and their large-scale implications
• Long-term monitoring of primary production in the Gullmar Fjord
• Feeding and production in cladocerans
Recent projects

• Baltic zooplankton cascades, BONUS project 2009-2011
• A new invader in the Baltic Sea—Feeding and ecosystem impact by the ctenophore Mnemiopsis leidyi
• Assessment of community structure and seston quality effects on plankton carbon fluxes at two contrasting coastal sites
• Retinal development in flat fish larvae- the effect of dietary essential fatty acids
