| dc.description.abstract | Protein electrophoretic analysis of nuclear-gene variation and restriction fragment length polymorphism (RFLP) analysis of mitochondrial (mt)DNA was used to assess spatial heterogeneity among six samples of undulus dis from the Gulf of Mexico and Atlantic coast of Florida. Significant heterogeneity was revealed among sampled localities in both nuclear-gene and mtDNA allele frequencies. No consistent geographic pattern of genetic diversity was detected. UPGMA cluster analyses revealed similarities among localities from the western Gulf of Mexico and from Florida. Individuals from the site sampled at Mobile Bay, Alabama, were divergent genetically from all other samples. Maximum-parsimony analysis revealed one geographically cohesive clade that contained haplotypes sampled from the site at Mobile Bay. undulus ndis appears to be subdivided spatially. This is consistent with the limited dispersal capabilities of the species. The structure of F. grandis was compared to the structure of a similar species F. heteroclitus. Comparisons revealed that the genetic structure in F. grandis is more extensive than that found in F. heteroclitus. | en |
