Fig. 1From: Microbiome species diversity and seasonal stability of two temperate marine sponges Hymeniacidon perlevis and Suberites massaAlpha diversity matrices (observed, Shannon diversity index, Simpson diversity index) for A) H. perlevis and S. massa, B) H. perlevis and associated seawater and C) S. massa and associated seawater. Significant differences between each group are measured by Kruskal-Wallis one-way ANOVA (*= p ≤ 0.05, **= p ≤ 0.01, ns = not significant). Full alpha diversity values and statistics can be found in Supplementary Tables 2–3.Back to article page
