Genetic differentiation in Littorina saxatilis (Gastropoda)

  • T. P. Snyder
  • J. L. Gooch


Littorina saxatilis, an ovoviviparous gastropod, displays considerable morphological variability, perhaps due to limited dispersal abilities. Gene and genotype frequencies of 2 polymorphic enzymatic loci were determined electrophoretically for 7 populations of L. saxatilis, to estimate degree of population differentiation. Results show that significant population differentiation may occur over distances of as little as 2 km, while widely separated populations may be nearly identical. An index of probability of genotypic identity calculated for populations of L. saxatilis shows variable and heterogeneous values. Comparison of this index for L. saxatilis with an index for 12 populations of Nassarius obsoletus —which possesses strong dispersal abilities due to long-term veliger larva and high, homogeneous indices of probability of genotypic identity between populations — indicates a strong correlation between population differentiation and dispersal ability of the organism. Possible factors influencing population differentiation in L. saxatilis are discussed.
