Data from: Parallel tagged next-generation sequencing on pooled samples – a new approach for population genetics in ecology and conservation

Next-generation sequencing (NGS) on pooled samples has already been broadly applied in human medical diagnostics and plant and animal breeding. However, thus far it has been only sparingly employed in ecology and conservation, where it may serve as a useful diagnostic tool for rapid assessment of species genetic diversity and structure at the population level. Here we undertake a comprehensive evaluation of the accuracy, practicality and limitations of parallel tagged amplicon NGS on pooled population samples for estimating species population diversity and structure. We obtained 16S and Cyt b data from 20 populations of Leiopelma hochstetteri, a frog species of conservation concern in New Zealand, using two approaches – parallel tagged NGS on pooled population samples and individual Sanger sequenced samples. Data from each approach were then used to estimate two standard population genetic parameters, nucleotide diversity (π) and population differentiation (FST), that enable population genetic inference in a species conservation context. We found a positive correlation between our two approaches for population genetic estimates, showing that the pooled population NGS approach is a reliable, rapid and appropriate method for population genetic inference in an ecological and conservation context. Our experimental design also allowed us to identify both the strengths and weaknesses of the pooled population NGS approach and outline some guidelines and suggestions that might be considered when planning future projects

Sample details of Leiopelma hochstetteri individuals used in the pooled samples next-generation sequencing (NGS) approach. For each sample species, sampling location, population number, sample number, Cyt b Genbank accession number, 16S Genbank accession number and geographical coordinates of the sampling location are provided. This table corresponds to a modified supplementary material that is available with the online version of the article Fouquet et al. 2010, Conservation Genetics, 11, 907-919 (doi:10.1007/s10592-009-9935-8). Accession numbers in bold indicate unsuccessful PCR amplifications for the given locus and individual. Note that the sequences deposited in the Genbank under these accession numbers are sequences generated by Sanger sequencing in the study of Fouquet et al. 2010
