Aims. To evaluate how equilibrium (ETIB) and niche-based (NTIB) island-biogeography frameworks jointly explain taxonomic and phylogenetic diversity in a temperate–subarctic, volcanically active archipelago. Location. Kuril Islands, northwestern Pacific (44°–50° N). Time Period. Present. Taxon. Vascular plants. Methods. We compiled island-level floras. We quantified species richness (SR) and phylogenetic diversity metrics and related them to latitude, area, distance, a composite isolation index, elevation, volcanic bedrock cover, vegetation-type diversity and aggregated climatic indices. Analyses combined linear and second-order polynomial regressions, β-diversity partitioning, non-metric multidimensional scaling and structural equation models. Results...
