Data set on chrysophytes algae in water bodies with territories above the 60th parallel north

The dataset includes a list of species of chrysiphytic algae from different water bodies located north of 60 degrees N. A set of species was formed on the basis of analysis of data from 193 scientific publications. In addition, the data contains information on T water temperature, pH, conductivity in the sampling period and month of sampling.<br>APPENDIX S1 - Integrated Data Table including the species composition and hydrochemical parameters (pH, Т, conductivity) of all 193 analyzed water bodies located above the 60th parallel north.<br>APPENDIX S2 - Results of the PERMANOVA analysis with AICc estimates for the selection of the most optimal linear combination of abiotic factors influencing the species composition of chrysophyte algae.<br>APPENDIX S3 - Species list of silica-scaled chrysophytes and their distribution in study regions (numbered as in Table 1). Geographic distribution types according to Kristiansen (2000, 2008): (cp) cosmopolitan, (wd) widely distributed, (sc) scattered, (bp) bipolar, (end) endemic, (ab) arctoboreal. Species occurring in in ancient floras (from Siver et al., 2013, 2015): (*) species similar to a fossil taxon (relict species); (**) species closely related to a fossil taxon; (***) relict species M. lancea that is similar in scale structure to two modern species, M. intermedia and M. corcontica.<br>APPENDIX S4 - Heat map of species representation in various water bodies. Filled rectangles at the intersection of rows and columns indicate that the species was present in the sample under study. The columns and rows of the heatmap are ordered according to the clustering results. Dendrograms of the clustering of regions and species according to the similarity of the representation spectra are presented in the left and upper parts.<br>
