Marine Chemical Ecology

Chemical substances play an important role in the interaction between all living organisms and their environment. The research that considers the impact of naturally occurring substances in the interaction between organisms, is called chemical ecology. Research in chemical ecology in marine environments is still in the beginning of its exploitation and it is reasonable to assume that it has a great potential. Many groups of plankton, algae and sessile animals in the sea produce a variety of different, often unique, types of molecules. These molecules probably function as protection against different kinds of attacks. Chemical signals in water are of vital importance for most organisms behaviour and reproduction, e g settlement of larvae and spores.

Areas of interest:

  • Chemical defence in marine organisms against marine fouling and other attacks
  • Settlement of marine larvae and spores with focus on signal / receptor-system
  • Toxic algae blooms: Induced signals and also physiological effects and adaptations in mussels
  • Effect of environmental changes on chemical signal systems and the production of chemical defence molecules (stress indicators)

PhD projects

Industrial interest and regional effects
In the long run several positive spin-offs are expected both on local and regional level. Research and development on bioactive substances in marine organisms have a great potential for establishment and development of biotechnical companies based on new discoveries and innovations.

Facilities:

The chemical ecology laboratory can provide both standard and state-of-the-art laboratory equipment for extraction, isolation, identification and quantification of natural products. Also several cultured and wild organisms are available, eg for bioassay-guided-fractionation of extracted metabolites.

Special instrumentation includes:

  • Liquid Chromatography-Mass Spectrometer (Ion-trap)
  • Gas Chromatography-Mass Spectrometer (Electron Impact and Chemical Ionization)
  • Analytical and preparative High Performance LiquidChromatography-systems with UV-, fluorescens- and refractive index-detectors
