Polymorphism in relation to habitat in the snail Cepaea hortensis in Iceland.
Polymorphism for shell colour and banding pattern in Cepaea hortensis was studied in a confined area in south Iceland. Morph freqquencies can be related to habitat. Yellow unbanded snails are more frequent in grassland and herb meadows thatn in “darker” habitats such as in ddense Angelica . Fused ba...
