Allometric Scaling in Environmental DNA Concentration of Japanese Eel Anguilla japonica Confirmed Under Laboratory and Natural Conditions 日本鳗 (Anguilla japonica) 环境 DNA 浓度中的异速生长标度在实验室和自然条件下得到证实

open access: yesIntegrative Conservation, Volume 4, Issue 4, Page 675-685, December 2025.
We demonstrated that Anguilla japonica eDNA concentration was allometrically scaled with their body size in both the laboratory and riverine environments. Integrating body size allometry has the potential to improve population abundance estimates in the field, whereas further clarification is required for understanding eDNA production mechanisms ...
