Unjustifiably Ignored: Reflections on the Role of Benthos in Marine Ecosystems,deed be one of the key facets of benthic research, they would like to stress that this is not simply a one-way interaction and the benthos influences pelagic processes in many ways. Furthermore, benthic processes have intrinsic values that go much beyond the value as a resource for human use or as a

Natural Variability and the Effects of Fisheries in the North Sea: Towards an Integrated Fisheries the species studied the fishing mortality appeared to range from 7 to 48%. Long term observations indicate that stocks of several species declined and some species disappeared from the southern North Sea..So far, attempts to control overfishing failed. Measures to regulate fisheries should be integ

Macrofaunal biomass ranged from 0.9 to 10g dw/m. while density ranged from 100 to 8000 ind/m.. Meiofauna abundance ranged from 100 to 8000 ind/10cm., and biomass from 0.1 to 1.7g dw/m.. It is proposed that the suite of taxa occupying intertidal flats on Spitsbergen depen

Conclusions and Recommendations,iods of up to thousands of years. Additionally, coastal and near-shore sediments are sites for accumulation of contaminants. The economic value of services for coastal areas has recently been estimated by Constanza et al [3] to be in the order of $12,568 10. y.. For the world these services are far
