Little information is available about glacier ice algae interactions with other microbial communities within the surface ice environment, including fungi, which may be important for sustaining algal bloom development. To address this substantial knowledge gap and investigate the nature of algal-fungal interactions, an ex situ co-cultivation experiment with two species of fungi, recently isolated from the surface of the Greenland Ice Sheet (here proposed new species Penicillium anthracinoglaciei Perini, Frisvad and Zalar, Mycobank (MB Microbial ecologyInteractions of Fungi and Algae from the Greenland Ice Sheet.PMC10293465J4-2549DNRF137856416NE/M021025/1P1-01706755462871P1-0198Zalar PFrisvad JCNicholes MPerini LLikar MWilliamson CAnesio AMGunde-Cimerman NGostincar CKostanjsek RfalseInteractions of Fungi and Algae from the Greenland Ice Sheet.Heavily pigmented glacier ice algae Ancylonema nordenskiöldii and Ancylonema alaskanum (Zygnematophyceae, Streptophyta) reduce the bare ice albedo of the Greenland Ice Sheet, amplifying melt from the largest cryospheric contributor to eustatic sea-level rise.
