  • The systemic discovery of metal–small-molecule complexes from biological samples is a difficult challenge. Now, a method based on liquid chromatography and native electrospray ionization mass spectrometry has been developed. The approach uses post-column pH adjustment and metal infusion combined with ion identity molecular networking, and a rule-based informatics workflow, to interrogate small-molecule–metal binding.

  • A characteristic of costal-pelagic fishes is their large population size fluctuations, yet the drivers remain elusive. Here, the authors analyze a 45-year timeseries of nitrogen stable isotopes measured in larvae of Northern Anchovy and find that high energy transfer efficiency from the base of the food web up to young larvae confers high survival and recruitment to the adult population.

  • Molecular networking connects molecules based on their fragment ion mass spectra (MS2), but may leave adduct species from the same molecular family separate. To address this issue, the authors develop a networking approach that fuses MS1- and MS2-based networks and integrate it into the GNPS environment.

  • A mesocosm heating experiment reveals that corals stressed by bleaching and/or heating exude compositionally distinct dissolved organic matter, which in turn yields elevated microbial loads and may increase abundance of copiotrophic and putatively pathogenic bacterioplankton on stressed coral reefs.
