Populations of the polymorphic land snail Cepaea nemoralis (L.) from Deepdale, Derbyshire, UK, sampled in 1965-67, showed a pattern of area effects, with steep clines among groups of populations differing in shell colour and banding morph frequencies. In 2010 most of these populations were resampled. In particular a continuous transect made in 1967 of 42 18.34m x 18.34m quadrats across a steep cline in several morph frequencies was completely resampled. In the dale as a whole, yellow shells had increased in frequency. In the transect the frequencies of banding morphs showed no significant changes, but colour morphs showed some changes. Pink shells had increased in frequency in a section in which scrub had developed, and brown shells had inc...
