This SOP standardises how to collect, extract, document, and preserve marine microscopic/meiofaunal/interstitial animals for genomic research. It covers the full pipeline from pre-collection planning (permits, logistics, safety, vouchering and repository coordination) through field sampling, lab extraction and sorting, identification and imaging, and DNA/RNA preparation via snap-freezing or other preservatives. Because whole specimens are usually consumed for sequencing, the SOP emphasises metadata ...

Within the Biodiversity Genomics Europe project, the "High Mountain Systems - Arthropods" case study was designed to evaluate how arthropod communities change along altitudinal gradients in seven selected mountain systems across different countries in Europe, establishing baseline sampling in mountain ranges to track biodiversity shifts associated with climate change. This SOP describes the sampling design and fieldwork methodology for retrieving arthropod bulk samples for metabarcoding analyses. ...
