Tabula rasa in the Patagonian Channels II: The cushion peat bog species Astelia pumila (Asteliaceae) and Donatia fascicularis (Stylidiaceae) survived the last glacial in south‐central Chile

Abstract: Aim Plant phylogeographic data from the Patagonian Channels are scant and it is largely unknown how the extensive Quaternary glaciations affected the population dynamics of the region's major vegetation component, that is cushion peat bogs (Magellanic moorland). Whether ice‐age glaciers wiped out all terrestrial plant life or whether some populations persisted in situ remains unclear. We reconstructed the phylogeography of two dominant Patagonian cushion peat bog species, Astelia pumila (G.Forst.) Gaudich. (As… Show more

“…This is noteworthy because, during the LGM, Tierra del Fuego was not totally covered by ice and thus more suitable for potential periglacial refugia than the heavily glaciated western Patagonia. In line with this, recent molecular studies in plants failed to identify refugia in southwesternmost Patagonia (Pfanzelt et al, 2017, 2019). In this and other cases, the incorporation of multilocus data would be helpful to support further or discard the southern glacial refugia proposed.…”
