Wilkins, N. P. (with comment by Jeffrey Levinton) . 1973. 



Genetic variation in marine bivalvia (Mollusca) . Science 182(4115): 946. 



The author criticises a paper by Levinton (1973), abstracted elsewhere in 

 this bibliography, which concluded that the absolute and effective number of 

 alleles at the phosphohexose isomerase and leucine aminopeptidase loci in 

 6 species of bivalve mollusk from Long Island Sound decreased with depth of 

 burial within the sediment intertidally and with depth of water subtidally. 

 He argues that data available to Levinton were inadequate to support the 

 conclusions drawn. In his reply, Levinton stands by his argument. Among 

 other things he states that Mereenaria mereenaria is a very shallow 

 burrower. - J.L.M.

Genie variability in marine bivalvia: implications and applications in 

 molluscan mariculture. 10th European Symposium on Marine Biology, Ostend, 

 Belgium. Vol. I: 549-563. 



Changes in allele frequencies or genotype proportions may vary clinally over 

 large geographic areas, e.g., LDH in Mereenaria mereenaria. A great deal 

 remains to be done before genetic variability and its implications for 

 mariculture can be understood, but the stabilization of environmental 

 variation which accompanies hatchery production of poikilothermic inverte- 

 brates adds a strongly directional element to natural selection. In the 

 long term, a narrower range of genotypes may suffice for optimum fitness 

 under such stabilized conditions. - J.L.M.

A general evaluation of fishery production and trophic structure in 

 estuaries near Beaufort, North Carolina. Ctr. for Estuarine and Menhaden 

 Research, Bu. Comm. Fish., Ann. Rept. to AEC: 178-216 (xerox copy of ms) . 



This report deals primarily with community and trophic structures and energy 

 exchange rather than with particular species. Its importance to hard clam 

 fisheries lies in its discussion of levels of fishery production in relation 

 to basic productivity and possibilities for increasing sustainable yields 

 from fishery resources by manipulating food webs and shortening the trophic 

 chain by at least one link. (Abstracter's note: this was received 9 Nov 1977 

 through the SUNY-SB library. ) - J.L.M.
