• Advanced Photogrammetry to Assess Lichen Colonization in the Hyper-arid Namib Desert

      Hinchliffe, G; Bollard-Breen, B; Cowan, DA; Doshi, A; Gillman, LN; Rios-Murillo, A; Maggs-Kolling, G; Pointing, SB (Frontiers Media, 2017)
      The hyper-arid central region of the Namib Desert is characterised by quartz desert pavement terrain that is devoid of vascular plant covers. In this extreme habitat the only discernible surface covers are epilithic lichens ...
    • Global Diversity of Desert Hypolithic Cyanobacteria

      Lacap-Bugler, DC; Lee, KK; Archer, S; Gillman, LN; Lau, MCY; Leuzinger, S; Lee, CK; Maki, T; McKay, CP; Perrott, JK; de los Rios-Murillo, A; Warren-Rhodes, KA; Hopkins, DW; Pointing, SB (Frontiers Media S.A., 2017)
      Global patterns in diversity were estimated for cyanobacteria-dominated hypolithic communities that colonize ventral surfaces of quartz stones and are common in desert environments. A total of 64 hypolithic communities ...
    • Lipid Biomarkers in High-altitude Geysers With Resemblance to Hesperian Surfaces on Mars (El Tatio, Chile)

      Sánchez-García, L; Fernández-Martínez, MÁ; García-Villadangos, M; Blanco, Y; Cady, SL; Hinman, N; Bowden, ME; Pointing, SB; Lee, C-Y; Warren-Rhodes, K; Lacap-Bugler, D; Cabrol, NA; Parro, V; Carrizo, D (Copernicus Publications, 2019)
    • Niche Filtering of Bacteria in Soil and Rock Habitats of the Colorado Plateau Desert, Utah, USA

      Lee, KC; Archer, SDJ; Boyle, RH; Lacap-Bugler, DC; Belnap, J; Pointing, SB (Frontiers Media S.A., 2016)
      A common feature of microbial colonization in deserts is biological soil crusts (BSCs), and these comprise a complex community dominated by Cyanobacteria. Rock substrates, particularly sandstone, are also colonized by ...
    • Subsurface Microbial Habitats in an Extreme Desert Mars-analog Environment

      Warren-Rhodes, KA; Lee, KC; Archer, SDJ; Cabrol, N; Ng-Boyle, L; Wettergreen, D; Zacny, K; Pointing, SB; NASA Life in the Atacama Project Team (Frontiers Media, 2019)
      Sediments in the hyper-arid core of the Atacama Desert are a terrestrial analog to Mars regolith. Understanding the distribution and drivers of microbial life in the sediment may give critical clues on how to search for ...
    • Taxonomic and Functional Diversity of Soil and Hypolithic Microbial Communities in Miers Valley, McMurdo Dry Valleys, Antarctica

      Wei, ST; Lacap-Bugler, DC; Lau, MC; Caruso, T; Rao, S; de Los Rios, A; Archer, SK; Chiu, JM; Higgins, C; Van Nostrand, JD; Zhou, J; Hopkins, DW; Pointing, SB (Frontiers Media S.A., 2016)
      The McMurdo Dry Valleys of Antarctica are an extreme polar desert. Mineral soils support subsurface microbial communities and translucent rocks support development of hypolithic communities on ventral surfaces in soil ...
