Likewise, DNA metabarcoding can be used to monitor biodiversity.

同样地，DNA 复合条形码还能用于监测生物多样性。

While metabarcoding can detect elusive animals like the Canada lynx, it can also help scientists identify invasive species.

DNA 复合条形码不仅可以帮助科学家监测像加拿大猞猁这样行踪不定的动物，也帮助科学家识别那些入侵的物种。

Fortunately, eDNA and metabarcoding give us the tools to document rapid change in real time.

幸运的是，eDNA 和元条形码为我们提供了实时记录快速变化的工具。

Using a technique called DNA metabarcoding, researchers can take a sample from the environment and learn which organisms are in it or have recently passed through it.

通过使用 DNA 复合条形码这技术，研究者们可以通过检测从环境中所收集到的样本，进而得知该样本中包含哪些物种或是近期哪些物种经过此地。

The process of DNA metabarcoding starts with an environmental sample like a core of soil, a vial of water, some feces, an insect trap, or even the blood from leeches' stomachs.

在使用 DNA 复合条形码之前，我们需要收集相关环境样本。像是一份核心土壤，一小瓶水，一些排泄物，一个捕虫器，甚至是来自水蛭胃里的血液都能作为很好的样本。
