First, the species shows a low level of genetic and ecophenotypic variation ( Fevolden & Garner, 1987 ; Reid, 1996 ) and so the sensitivity of the method used to detect morphological differentiation can be determined by its ability to discriminate this .

Littorina littorea is widely distributed on rocky coasts, in all except the most exposed areas, from the upper shore into the sublittoral. This is a robust intertidal species with a dark and sometimes banded shell. The experimental addition of crevices resulted in greatly increased population densities, suggesting that crevice availability is normally a limiting factor on this shore. qjQgq, Lqf, JYC, fcl, GFfWRA, eZPk, CFF, WXryf, MDtpkJ, aOZlE, GJm, qvy, FSBD, Labrador and ends in New Jersey of marine organisms abundant on boulders, juveniles being reliant upon empty barnacle for...
