A multi-year (2007-2025) moth community data across the islands of southern South Korea

This dataset contains standardized multi-year community data of moth assemblages collected across multiple islands. The dataset is designed to support analyses of spatial and temporal beta diversity, community assembly processes, and biodiversity responses to environmental gradients. The dataset includes site-level species abundance data, derived beta diversity metrics, and island-level environmental variables. Together, these components enable investigation of species turnover, nestedness, and community dynamics across both spatial and temporal scales.
