| Abstract: | Puffins, climate change and fisheries Long term changes in north Atlantic weather leading to climate changes have measurable influences on marine eco systems. Seabirds have to cope with changes in the food web, driven by rising SST and other abiotic factors. The Atlantic Puffin is a good example for this. We can study its breeding success and colony size as measurements for changes in the food resources, mainly sandeels or herring over a wide area from the southern boreal to the arctic waters and from the east to west coast colonies of the Atlantic ocean. The findings show that population changes and breeding success in several seabird species like the Puffin and Common Guillemots or Black‐legged Kittiwakes as well show strong correlations to declining sandeels as a consequence of intensive industrial fishing, changes in SST and plankton, especially the most abundant copepod Calanus finmarchicus, development. |
