    Distinctive characters of Nostoc genomes in cyanolichens 
    Gagunashvili, Andrey; Andrésson, Ólafur (Springer Nature, 2018-06-05)
    Background Cyanobacteria of the genus Nostoc are capable of forming symbioses with a wide range of organism, including a diverse assemblage of cyanolichens. Only certain lineages of Nostoc appear to be able to form a close, stable symbiosis, raising ...

    Faster nitrogen cycling and more fungal and root biomass in cold ecosystems under experimental warming: a meta‐analysis 
    Salazar, Alejandro; Rousk, Kathrin; Jónsdóttir, Ingibjörg Svala; Bellenger, Jean‐Philippe; Andrésson, Ólafur (Wiley, 2019-12-31)
    Warming can alter the biogeochemistry and ecology of soils. These alterations can be particularly large in high northern latitude ecosystems, which are experiencing the most intense warming globally. In this meta‐analysis, we investigated global trends ...

    Fungi in liverwort-based biocrust 
    Guðmundsdóttir, Petra Landmark; Andrésson, Ólafur (Agricultural University of Iceland, 2019)
    Fungal distribution in a liverwort-based biocrust was examined at different depths (0, 5 and 20 mm) by direct counting using both light and fluorescence microscopy. The DNA-based taxonomic composition of fungi was also determined and differences between ...
