Biogeochemistry of Water and Sediment in the OB and Yenisey Estuaries, water column (for both dissolved and particulate forms of elements). The influence of biotic factors is more marked in the Yenisey estuary due to higher photosynthetic activity and primary production of phytoplancton.预知 发表于 2025-3-23 23:08:41

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 aMhc-Molecule 发表于 2025-3-24 09:17:30
Natural Variability and the Effects of Fisheries in the North Sea: Towards an Integrated Fisheriesthe 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平淡而无味 发表于 2025-3-24 13:09:55
Community Compositon of Tidal Flats on Spitsbergen: Consequence of Disturbance?, from only one or two areas. 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 depenEnervate 发表于 2025-3-24 16:11:28
The Problem of Scale: Uncertainties and Implications for Soft-Bottom Marine Communities and the Assany large-scale environmental issues there is a lack of both appropriate controls and an ability to rigorously demonstrate effects. This has important implications for resource management concerning a trade-off between confidence and generality in environmental information and emphasises the need fo胎儿 发表于 2025-3-24 21:14:34

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 to be in the order of $12,568 10. y.. For the world these services are far
