Abstract
Genetic variability of the phosphoglucose isomerase (PGI) and phosphoglucomutase (PGM) loci are compared in Patella vulgata L. and P. aspera Lamark from two sites on the west and south coasts of Ireland. P. vulgata was less variable than P. aspera at these 2 loci, and in only 1 of 7 other loci briefly examined was P. vulgata more variable. Evidence is also presented that the PGI enzyme in P. vulgata is more stable at high temperature than that of P aspera. The significance of these observations is discussed in the light of, the different zonal distributions of these species on the shore.
