Allozyme data from Echinorhynchus gadi spp and Echinorhynchus brayi. Allozyme data are summarized in table 1 and figure 1 of the published paper (Wayland et al 2005). Comma separated value file with the following columns: 1: Plate (cellulose acetate gel) 2: Lane (lane on cellulose acetate gel) 3: Species 4: Specimen (unique identifier for acanthocephalan) 5: Host 6: ICES (International Council for the Exploration of the Sea) statistical rectangle (geographical region) 7-15: Genotypes for each of nine presumptive loci: GPI, LDH, MDH-1, MDH-2, PEP-1, PEP-2, PEP-3, PGM-1, PGM-2 This file also contains results of allozyme electrophoresis of the following acanthocephalan species (not reported in the published paper): Acanthocephalus anguillae Acanthocephalus lucii Echinorhynchus trachyrinci N.B. There is an error on page 143 of the published paper (Wayland et al 2005) in the naming of electromorphs at the MDH-2 locus. Under the subheading "Electrophoretic study" of the results section, are the following lines: "The absence of heterozygotes MDH-2*100/85 among the 88 individuals screened at this locus is strong evidence of complete reproductive isolation. Here, the species with the MDH-2*100/100 genotype is designated E. gadi sp. A and the species with the MDH-2*85/85 genotype is designated E. gadi sp. B." These lines should read: "The absence of heterozygotes MDH-2*120/100 among the 88 individuals screened at this locus is strong evidence of complete reproductive isolation. Here, the species with the MDH-2*120/120 genotype is designated E. gad sp. A and the species with the MDH-2*100/100 genotype is designated E. gad sp. B."
