What is Intraspecific variation in the population dynamics and growth of the limpet, Cellana tramoserica about?

Populations of the limpet Cellana tramoserica (Sowerby) from high, mid, and low intertidal regions, and from a subtidal zone, were studied at Cape Banks (N.S.W.), Australia. Individuals from the subtidal population had the largest mean and maximum shell size, the low and high shore populations were intermediate, while the midshore population had both the smallest mean and maximum size. The density of adults showed the reverse trend: the midshore region had the greatest adult population density while the subtidal population had the smallest density. The density of juveniles and recruits was negatively correlated with tidal height in the intertidal areas, but the density of both age-classes was smallest in the subtidal region. The rate of growth of individuals was negatively correlated to the adult density of a site; individuals from the subtidal population grew the fastest, while those from the midshore region grew the slowest. The level of adult mortality of the four populations was similar, with an annual rate of between 50-60%. Juvenile mortality did, however, differ among populations; reduced percentages of juveniles reached adult size in the mid and low shore populations than i
