Zusammenfassung
Chemical signals are important mediators of organismal interactions. These interactions significantly influence ecosystem structure and thus are crucial to understand. Ecologists and analytical chemists work closely together to identify the specific molecules regulating ecological interactions. However, limitations in the analytical techniques on the one hand and time-demanding bioassays on the other have been restraining chemical ecology research. Application of metabolomics techniques has recently led to significant advancement of the field. Here, we discuss modifications to the traditional bioassay-guided fractionation approach with metabolomics techniques. We focus on two challenging topics within chemical ecology, waterborne cues and single-cell investigations, to highlight how metabolomics techniques can succeed where traditional approaches have failed.
