Dear all, We are pleased to announce the upcoming Physalia online course: Eukaryotic (eDNA) Metabarcoding Dates: 14-18 July 2025 Format: Online Course website: ( https://www.physalia-courses.org/courses-workshops/course4/ ) This hands-on course offers an in-depth overview of metabarcoding techniques for the qualitative and quantitative assessment of biodiversity in natural communities. Participants will explore practical pipelines using short (Illumina)- and long (Nanopore)- data, and gain the skills to design and analyze their own metabarcoding projects. By the end of this course, participants will be able to: Understand the principles and workflow of DNA metabarcoding, including technical replication, sequencing depth, and methodological biases Recognize good laboratory practices for sample collection, DNA extraction, PCR, and library preparation Apply the APSCALE pipeline and BOLDigger for raw read processing and taxonomic assignment Use TaxonTableTools (TTT) for data filtering, alpha and beta diversity analysis, and result visualization Explore eDNA metabarcoding using Nanopore sequencing and understand its advantages and limitations in environmental applications Build local reference databases and design metabarcoding primers for custom applications Confidently troubleshoot and design their own metabarcoding projects with expert support This course is intended for researchers in ecology, biodiversity, evolution and community biology, as well as those in bioinformatics interested in ecological applications. Basic experience with Unix commands and R is recommended.
