There is evidence of recovery from symptoms of imposer in populations of dogwhelks Nucella lapillus (L.) from study sites on the Isle of Cumbrae (Scotland) and, in particular, on shores adjacent to the town of Millport. RPSI scores and the numbers of 'penis-bearing' females have decreased, and the numbers of dogwhelks on the shore have increased, between 1988 and 1993. Dogwhelks were not found at all at one site at Millport in 1988 but were abundant there by 1992-93.
