The advantages of going large: genome-wide SNPs clarify the complex population history and systematics of the threatened western pond turtle.

摘要: As the field of phylogeography has matured, it become clear that analyses one or a few genes may reveal more about history those than populations and species are targets study. To alleviate these concerns, discipline moved towards larger individuals genes, although little attention been paid to qualitative quantitative gains such increases in scale scope yield. Here, we increase number markers by an order magnitude over previously published work comprehensively assess phylogeographical well-studied declining species, western pond turtle (Emys marmorata). We present new analysis 89 independent nuclear SNP mitochondrial gene sequence scored for rangewide sampling >900 individuals, compare smaller-scale, genetic morphological analyses. Our enlarged data fundamentally revise our understanding evolutionary this lineage. results indicate from greatly increasing both substantial worth effort, particularly high conservation concern as turtle, where accurate assessments population prerequisite effective management.
