Icescape-scale metabolomics reveals cyanobacterial and topographic control of the core metabolism of the cryoconite ecosystem of an Arctic ice cap
Gokul, Jarishma K.; Mur, Luis A. J.; Hodson, Andrew; Irvine-Fynn, Tristram D. L.; Debbonaire, Aliyah R.; Takeuchi, Nozomu; Edwards, Arwyn (Peer reviewed; Journal article, 2023)Glaciers host ecosystems comprised of biodiverse and active microbiota. Among glacial ecosystems, less is known about the ecology of ice caps since most studies focus on valley glaciers or ice sheet margins. Previously we ... -
Marked Seasonal Changes in the Microbial Production, Community Composition, and Biogeochemistry of Glacial Snowpack Ecosystems in the Maritime Antarctic
Hodson, A.J.; Šabacká, Marie; Dayal, A.; Edwards, Arwyn; Cook, J.; Convey, Peter; Redeker, Kelly Robert; Pearce, D.A. (Peer reviewed; Journal article, 2021)We describe seasonal changes in the biogeochemistry, microbial community and ecosystem production of two glacial snowpacks in the maritime Antarctic during a cold summer. Frequent snowfall and low, intermittent melt on the ... -
Spatially consistent microbial biomass and future cellular carbon release from melting Northern Hemisphere glacier surfaces
Stevens, Ian T.; Irvine-Fynn, Tristram D. L.; Edwards, Arwyn; Mitchell, Andrew C.; Cook, Joseph M.; Porter, Philip R.; Holt, Tom O.; Huss, Matthias; Fettweis, Xavier; Moorman, Brian J.; Sattler, Birgit; Hodson, Andrew (Peer reviewed; Journal article, 2022)Melting glacier ice surfaces host active microbial communities that enhance glacial melt, contribute to biogeochemical cycling, and nourish downstream ecosystems; but these communities remain poorly characterised. Over the ...
