Last Glacial and Holocene dynamics override post-colonial disturbance in shaping genetic diversity of a heavily exploited palaeoendemic conifer, <em>Lagarostrobos franklinii</em>

The impact of past anthropogenic disturbance on the amount and distribution of genetic diversity is a key factor in determining the resilience of tree species to environmental change. This is particularly the case for narrowly distributed species where disturbance has impacted most of the species’ range. Here we examine the legacy of post-colonial logging and fire on patterns of genetic diversity in the Tasmanian palaeoendemic conifer Lagarostrobos franklinii (Podocarpaceae), a fire sensitive and slow growing rainforest tree valued for its durable timber. Thirty-three populations (12 of which represent primary stands) from across the species range were genotyped using eight nuclear SSRs (871 samples) and MIG-seq-based single nucleotide polymorphisms (254 samples). Genetic differentiation was relatively high for conifers (Fst of 0.113 and 0.143 for nuclear SSR and MIG-seq, respectively) with cryptic divergence between populations geographically close but in differing river catchments lik..., , # Last Glacial and Holocene dynamics override post-colonial disturbance in shaping genetic diversity of a heavily exploited palaeoendemic conifer, *Lagarostrobos franklinii* Dataset DOI: [10.5061/dryad.80gb5mm37](https://doi.org/10.5061/dryad.80gb5mm37) ## Description of the data and file structure The vcf file contains the filtered MIG-seq data for 254 individuals of *Lagarostrobos franklinii.* For population information of each individual see the 'Sample info' Excel file. ### Files and variables #### File: Sample_info.xlsx **Description:** A list of all individuals and the population they belong to #### File: L.franklinii_MIG-seq_data_845_SNPs.vcf **Description:** The filtered MIG-seq dataset ## Code/software The VCF file can be converted to other formats using VCFtools, Plink or Stacks populations and/or imported in R directly using a package like VcfR. ,
