Abstract Many taxa around the globe are threatened by often unexplained mass mortality events (MMEs), which can decimate populations and compromise key ecosystem functions. One example of a highly taxon facing frequent MMEs is freshwater mussels (Unionida). There has been recent increase in interest understanding causes mussel MMEs, but standardised methodologies for how best to respond them facilitate diagnoses unavailable. When an MME observed, swift appropriate sample collection imperative owing transient nature these phenomena. Here we provide structured guidance that will rapid sampling using as example. We set out procedures collection, preparation preservation. The outline improve our capacity diagnostic investigations other events, not only also across many taxa. This, turn, inform management responses.
