a The nearest taxon index (NTI) and (b) the net relatedness index (NRI) as functions of lava rock age (in days). The x-axis is presented on a broken scale to highlight changes over different time intervals. The horizontal dashed line at zero denotes the transition from phylogenetic clustering (NRI or NTI > 0), associated with strong environmental filtering, to phylogenetic overdispersion (NRI or NTI < 0), associated with competitive exclusion. c Processes of microbial community assembly for Fagradalsfjall samples at different age bins using the beta diversity component of NRI (βNRI) to partition deterministic processes where |βNRI| > 2, and the Raup Crick (RC) diversity metric to partition stochastic processes where |βNRI| < 2.
