TABLE 2.
Network level information from the different lichen guilds, including the number of compartments (Com.) within the network not connected via mycobiont–photobiont interactions; connectance (Con.) indicating the proportion of realized interactions; NODF nestedness metric with Z score (Z > 1.64 indicates significance at p = 0.05), relative nestedness (RN) values, and whether the result differs significantly from a random matrix (Sig.), also separately to mycobionts (NODF my.) and cyanobionts (NODF cy.); specialization within the network (H2’), web asymmetry (Web asy.) indicating the difference between the numbers of mycobiont taxa and cyanobacterial variants; partner diversity (Partner div.) indicating the diversity and evenness of distribution among the interactions; and niche overlap indicating the similarity of interactions between taxa, i.e., the sharing of the mycobionts (My.) or cyanobionts (Cy.).
