Beneath the surface: DNA metabarcoding reveals shifting biofouling patterns on marine artificial structures across season, depth, and substrate
Recent research illuminates the complex dynamics of marine biofouling, revealing how seasonal shifts, depth, and substrate type significantly influence community composition on artificial structures. Utilizing DNA metabarcoding across two seasonal periods and three depths, our study identified over 10,000 genetic variants, demonstrating that season explains the largest variation in biofouling biomass and diversity. These findings underscore the need for adaptive antifouling strategies considering interacting environmental factors—a perspective further explored in our related article, "Machine learning predictions for microbial eukaryotic plankton."
Compositional convergence of island demersal fish assemblages in the East Sea: a long-term trammel-net comparison between Dokdo and Ulleungdo
Rapid ocean warming is fundamentally reorganizing marine fish assemblages, yet definitive, long-term evidence of compositional convergence between adjacent island ecosystems remains limited. A recent study published by World Data Ocean analyzed two decades of standardized trammel-net surveys around Dokdo and Ulleungdo in the East Sea, revealing a significant decline in inter-island dissimilarity between 2013 and 2025.
