Environmental DNA (eDNA) Workflows & Biodiversity Calls — Hands-on

Build end-to-end environmental DNA (eDNA) pipelines from field sampling to defensible biodiversity calls. Learn contamination-safe collection and extraction, marker/primer selection, sequencing and QC, ASV/OTU inference, taxonomic assignment against curated references, and decision-grade reporting with occupancy/detection models and uncertainty quantification.
