eDNA snapshots of invasion, infection and extinction from a freshwater crayfish tragedy
For the first time, a devastating crayfish plague outbreak has been monitored from the onset to crayfish extinction using eDNA methodology. David A. Strand and colleagues surveyed a watercourse over three years and discovered a remarkable correlation between eDNA fluctuations and host-pathogen dynamics. Noble crayfish (Astacus astacus) are macroinvertebrates that can be found in both lotic and lentic freshwater systems across most of Europe. Previously … Continue reading eDNA snapshots of invasion, infection and extinction from a freshwater crayfish tragedy
