Risks and Opportunities for Locale Stakeholders of the North Sea
Anthropogenic activities, like air and water pollution, fisheries, tourism and exploitation of resources (oil, gas, sand etc.) have induced changes in marine ecosystems of expanding dimensions. One apparent global effect induced in particular by climate change is the shift in species range in marine flora and fauna influencing local biodiversity, population structures, food webs and the coexistence of many ecological and economical relevant species.
Some marine ecosystems are less affected, while other marine regions are suffering vastly from those changes. Species native to the North Sea (Blue mussel and cod) are migrating to colder and slower warming regions in the higher latitudes, whereas those species are exhibited to increasing ecological pressure through increasing sea temperatures and competition by Lusitanian species (Mediterranean mussel and European sea bass) immigration from lower latitudes at the southern border of their distribution range.
