TitleHigh diversity of lichens at 84 deg S, Queen Maud Mountains, suggests preglacial survival of species in the Ross Sea region, AntarcticaAbstractInvestigations of lichens collected in 1959/1960, 1963/1964 and 2003 from near the Beardmore Glacier in the southern Ross Sea region (84°S) have more than doubled the number of known lichen species in the area to around 30. The ranges of 15 species have been extended to 84°S. A lichen diversity hotspot has also been found along Ebony Ridge and its associated peaks where 28 of the species occur, a number equivalent to more northerly sites in the Ross Sea (e.g. Botany Bay 77^circS). Furthermore, 6 species had been previously recorded only from the Antarctic Peninsula region. In agreement with previous studies on mites and springtails from the same area, we suggest that these populations represent relicts that predate the present Ross Ice Shelf extension, with a possible age of 2,000,000 years or older.

The New Zealand Foundation for Research, Science and Technology (FRST), the University of Waikato Vice ChancellorÅ› Fund, and the Department of Biological Sciences, University of Waikato provided financial support. During completion of the research, TGAG and IDH were supported by the FRST grant, understanding, valuing and protecting AntarcticaÅ› unique terrestrial ecosystems: predicting biocomplexity in Dry Valley ecosystems, and TGAG and LGS by the Spanish Education Ministry grants POL2006-08405 and CTM2009- 12838-C04-01. Ulrike Ruprecht is thanked for assistance in identifying Lecidea species. Barbara Polly at the Domininion Museum, Wellington, is particularly thanked for excellent curation of the Antarctic samples and for drawing our attention to the collections. Catherine Beard is thanked for drawing Figure 2b.
