Abstract The processes driving species co‐occurrence across scales are poorly understood. Bryophytes especially interesting in this respect because, while they disperse over long distances and have broad distributions, particularly affected by local conditions due to their small size. We investigated the relationship between pairwise associations within epiphytic bryophytes macroclimatic niche similarities taxonomic relatedness at four (global, regional, habitat microhabitat). used community data for 2000 trees from 107 forests northwest Iberian Peninsula, global occurrences 33 with calculate each scale bioclimatic similarity. also obtained distance matrices bibliography as a proxy phylogenetic species. Co‐occurrence relates similarity all scales, but decreases towards smaller scales. Taxonomic affinity was good indicator of not explained finest Interestingly, most relationships positive or neutral rather than negative, although direction approximately 7% these shifts microhabitat negative regional scale. Macroclimatic requirements progressively less important coexistence diminishes, probably effect unmeasured interactions, community‐level processes, microclimatic variations. Synthesis . Our results highlight that interactions may be least ones, if more, bryophyte They underscore patterns shift critical role both macro‐ microenvironmental shaping life strategies persistence populations plant group population dynamics characterized extensive geographic distributions. implications findings go beyond relevance ecology, challenging prevailing assumption limiting primarily shape ecological communities.
