Genetic variation and differentiation in Armadillidium vulgare (Isopoda: Oniscoidea)


Genetic variation was examined with polyacrylamide and starch gel electrophoresis at 22 loci in 8 populations of Armadillidium vulgare. Polymorphism was observed at 9 loci, and the average heterozygosity was 3.0%. Heterozygosity was low when compared to most invertebrates but was similar to that reported for certain decapods. A significant heterozygote deficiency occurred in most populations of A. vulgare and considerable genetic differentiation was observed among isopod populations. © 1985 Dr W. Junk Publishers.
