Tice&Carlon_JEB_data.xlsx Spreadsheet Explanation Locus Information Worksheet: This worksheet summarizes information about the loci used in the study. Primer: primer combination that generated the AFLP locus (possible values from AF; see paper for primer sequences for each combination). Locus Number: number to identify each individual locus Size: size of the locus in base pairs Genotypes by Locus # Worksheet: This worksheet gives the genotypes of all snails in the study for all 1073 loci. Each locus is labeled with a unique number. A value of 0 in a locus column means the locus was absent for that particular snail, while a value of 1 means the locus was present. Sample #: number to identify each individual snail Morph: morphotype of the snail (smooth or rough) Island: island where the snail was collected (Oahu or Kaua’i) Site: site where the snail was collected (Kealia, Kewalo, Port Allen, Puaena) Genotypes by Locus Size Worksheet: This worksheet gives the genotypes of all snails in the study for all 1073 loci. Each locus is labeled by its size (in base pairs). A value of 0 in a locus column means the locus was absent for that particular snail, while a value of 1 means the locus was present. Sample #: number to identify each individual snail Morph: morphotype of the snail (smooth or rough) Island: Island where the snail was collected (Oahu or Kaua’i) Site: Site where the snail was collected (Kealia, Kewalo, Port Allen, Puaena)
