ABSTRACT: One of the oldest published records of benthic fauna
was made in 1893 by dredging along transects from soft bottoms, sand and shell
debris to rocky bottoms in an archipelago at the Swedish Skagerrak coast. Three
of the transects were revisited in 2010 and then fewer taxa were recorded and
the shared species between sampling dates at the transects were only between 8%
and 12%. The main causes for the drastic changes are suggested to be
large-scale eutrophication changing the vegetation composition and variation of
climatic factors.
