Biological systematics is the foundation of biodiversity and evolutionary studies. Systematics is important not only for our understanding of evolutionary processes and to describe the diversity of Life, but also for management of the environment and its biodiversity. The last few decades have witnessed a growing importance of integrated approaches which involve the use of morphology, as well as molecular tools, more recently using omics-based techniques. This integrative approach greatly boosted research in systematics, also providing the opportunity to deeper insights on the evolution of morphological characters and their utility for taxa description. The recent development of omic disciplines and their use in systematics studies are offering further opportunities but, at the same time, coming with new challenges. This symposium – accepting empirical, methodological, and theoretical contributions – aims to capture and to further catalyse this ongoing shift. We particularly welcome contributions using two or more data types (e.g., morphological, genomic, transcriptomic, ecological data) either in parallel (e.g., integrative taxonomy) or using one to support the other (e.g., studies of trait evolution, research ascertaining the utility of morphological character using molecular data). Ultimately, this symposium aims to offer updated views of systematics and to encourage a constructive discussion among experts.
