Dried blood spots (DBSs) are gaining popularity for biomarker analyses in ecological research due to their advantages for use in field‐based research and in remote settings; however, many DBS biomarkers remain unvalidated. We validated the application of compound‐specific stable nitrogen isotope analyses of amino acids (CSIA‐AAs) to field‐prepared DBSs for determining trophic positions of wild‐caught Arctic char (Salvelinus alpinus).

使用氨基酸的氮稳定同位素分析验证干血斑取样以确定北极炭的营养位置

干血斑 (DBS) 在生态研究中的生物标志物分析中越来越受欢迎，因为它们在实地研究和偏远环境中具有优势；然而，许多 DBS 生物标志物仍未得到验证。我们验证了氨基酸化合物特异性稳定氮同位素分析 (CSIA-AAs) 在现场制备的 DBS 中的应用，以确定野生捕获的北极炭 ( Salvelinus alpinus ) 的营养位置。
