Recent changes in abundance of intertidal barnacles in south-west England: a possible effect of climatic deterioration

Extract

Annual surveys carried out in south-west England since 1949 show that the arctic-boreal barnacle, Balanus balanoides, which was uncommon or rare in i960, has increased greatly in abundance during the colder years since then. Its numbers now approach those recorded in the 1930's, and there has been a corresponding reduction in abundance of the warm-water species, Chthamalus stellatus.
