Paleodistribution of the alerce and cypres of the Guaitecas during the interstadial stages of the Llanquihue Glaciation: The authors have collected at eight different sites subfossil tree trunks of alerce Fitzroya cupressoides Mol. The tree trunks were in situ and very well preserved. According to six preliminary radiocarbon alredefor showing finite ages between Conifer tree trunks at both sites are associated with organic silt and peat underlying a thick succession m of laminated grey silt lacustrine rhytmite and capped by fluvioglacial sand and gravel which correspond to the Last Glacial Maximum.

The pollen spectra of the tree-containing organic deposits at the base of the succession are dominated mainly by arboreal forest taxa: Nothofagus dombeyi -type and several conifers, Fitzroya cupressoides Mol.

Don Florin, Saxe-gothaea conspicua Lindl. The spectra suggest a relatively warm and wet interstadial during middle Llanquihue glaciation.


These forests have a disjunct distribution at present, with populations present on the summits and high elevation sites of both mountain ranges Andes and Coastal in the Lake Region, and small isolated populations present at alededor elevations.

Alrededor Del Torno

This montane distribution is attributed to increasing trno since the late glacial and during the Holocene, and hence, the populations at lower elevations would be relicts from glacial stages, as it is suggested by a greater degree of genetic divergence present in these relicts as compared to the high elevation populations.
