Background and aims: Plant‐derived, ester‐bound substituted fatty acids have been used for decades as biomarkers to identify input of plant materials in sediments and soils. However, the long‐term decomposition patterns of these biomarker compounds under natural conditions are not well understood, although this is a basic prerequisite for quantitative biomarker applications.

凋落物分解过程中针状和根状生物标志物的稳定性

背景和目的：源自植物的酯键合取代脂肪酸已被用作生物标记物，以识别沉积物和土壤中植物原料的输入。然而，尽管这是定量生物标志物应用的基本前提，但人们对在自然条件下这些生物标志物化合物的长期分解模式还没有很好的了解。
