Fig. 6: Ancylonema spp. ITS2 haplotype diversity and phylogenetic placement from Robert Island and wider studies.
From: Surface darkening by abundant and diverse algae on an Antarctic ice cap
Sequence-structure phylogenetic maximum-likelihood tree of Ancylonema ITS2 haplotypes from Robert Island and elsewhere, including reference and environmental sequences for A. nordenskioeldii, A. alaskanum, and Ancylonema sp.22,37, environmental sequence haplotypes from Greenland, Svalbard, Alaska, Sweden, and the European Alps37,39,40, and an outgroup reference, C. cushlekae. Sequence data for “Remias_2023 H2” are in supplementary data for Remias et al. (2023)37. Haplotype occurrence by region is indicated in the ‘Region’ column. Maximum CBC positions between members of assigned clades are indicated in the inset table. Read distributions for ITS haplotypes are in Table S2.
