Variation in Cepaea populations over 42 years: climate fluctuations destroy a topographical relationship of morph-frequencies

Cepaea hortensis (Gastropoda: Pulmonata) populations in Hertfordshire, England, originally sampled in 1964-66, and sampled again in 1990, were sampled in 2007. Although the general pattern of shell colour and banding polymorphism remained stable, a significant trend for a reduction in the frequency...
