Work Description

Title: Data from "Genomic evidence of a widespread southern distribution during the Last Glacial Maximum for two eastern North American hickory species" Open Access Deposited
Attribute Value
  • Genotypes of bitternut hickory (Carya cordiformis) and shagbark hickory (Carya ovata) were generated from rangewide populations of each species. Individuals from each population were sequenced using double-digest Restriction-site Associated DNA (ddRAD) sequencing. Single nucleotide polymorphisms (SNPs) were identified and genotyped using the program Stacks (Catchen et al. 2011 G3: Genes, Genomes, Genetics; Catchen et al. 2013 Molecular Ecology). Occurrence records of each species used in species distribution modelling were obtained from the US Forest Service Forest Inventory Analysis Database (
  • Raw SNP genotypes are provided in STRUCTURE format, with a maximum of one SNP reported per ddRAD locus. The files "caryco_SNP.str" and "caryov_SNP.str" are genotypes for Carya cordiformis and Carya ovata, respectively. The first column of each file is the individual name, the second column is the population (see original publication for information on population locations), and the remaining columns are genotypes of individual SNPs. Rows represent individuals, with the diploid genotypes contained on two lines per individual. Missing data are entered as "0" (zero). The first row is a header with a unique identifier for each SNP.

  • Occurrence records for each species are provided in the file "occs_carya.csv" and contain the latitude and longitude of each record.
