Change strategy to save diversity of species
Date:4/18/2011

Active efforts are required to preserve biodiversity in the seas that far most people are in agreement. But in our enthusiasm to save uncommon species, we sometimes miss the common species that form the basis of marine ecosystems. 'Change strategy' is the challenge to the authorities from researchers at the University of Gothenburg, Sweden.

An inconceivably large proportion of the animals that live in the seas are so uncommon that it is difficult to find more than a few specimens. Committing most resources to saving individual species is not just an expensive business it would also risk destroying the foundation for ecosystems, the research of Professor Kerstin Johannesson shows.

Her research team is able to demonstrate that it is the common species that are of really great significance for ecosystems, by establishing habitats for other species. It is therefore in all probability the most common species that determine the future of all species. If the common species disappear, it will have great consequences.

An alarming example of what can happen is that the cod populations in the fjords of the Bohusln coast have almost without exception disappeared. These fjords have consequently lost one of their most important species. It can have far-reaching consequences for several other species when the environments of the shallow bays change.

"Without the big predatory fish, the sea-grass meadows become clogged, with the result that the shallow bays no longer act as larders and nurseries for inshore fish. While life slowly dies out, the blame is put on eutrophication."

Kerstin Johannesson's research is concerned with how different populations within one species may be so genetically different that they actually do not have very much to do with each other, and that in particular they are not interchangeable. If a local population disappears, it will not automatically be replaced by individuals from another population migr
