eDNA recovered over 10 days of daily sampling for 3 different densities of C. maenas (1, 3, or 6 crabs) within 3 separate temperatures: A 6.7 ℃, B 12.8 ℃, C 17.8 ℃. The grey shade within each graph represents when crabs were present in the containers, crabs were removed on day 7. Mean ± SEM, n = 5 per data point. Data points are nudged slightly along the x-axis to avoid overlaying of the respective symbols. The fourth panel (D) shows a representative standard curve that was used to quantify the data
