Data from: Rethinking long-term vegetation dynamics: multiple glacial refugia and local expansion of a species complex

Joseph D. Napier, Guillaume De Lafontaine, Katy D. Heath & Feng Sheng Hu
Evidence is accumulating that some arcto-boreal plant taxa persisted through the Last Glacial Maximum (LGM) in Alaska and adjacent Canada. However, the spatial patterns of glacial persistence and associated postglacial colonization remain largely unknown. In this study, we investigated the LGM refugia of an alder (Alnus) species complex (n = 3 taxa) and assess the spatiotemporal dynamics of Alnus in this vast region. Specifically, we conducted high-throughput DNA sequencing (ddRADseq) on Alnus foliar samples collected...
