The paradox of methane oversaturation in oxygenated surface water has been described in many pelagic systems and still raises the question of the source. Temora sp. and Acartia sp. commonly dominate the surface and subsurface waters of the central Baltic Sea. It is hypothesised that their gut microbiome at least partly contributes to the methane anomaly in this ecosystem. However, the potential pathway for this methane production remains unclear. Using a microcapillary technique, we successfully overcame the challenge of sampling the gut microbiome of copepods <1 mm. 16S rRNA gene amplicon sequencing revealed differences among the dominant bacterial communities associated with Temora sp. (Actinobacteria, Betaproteobacteria and Flavobacteriia) and Acartia sp. (Actinobacteria, Alphaproteobacteria and Betaproteobacteria) and the surrounding water (Proteobacteria, Cyanobacteria and Verrucomicrobia), but also intraspecific variability. In both copepods, gut-specific prokaryotic taxa and indicative species for methane production pathways (methanogenesis, dimethylsulfoniopropionate or methylphosphonate) were present. The relative abundance of archaea and methanogens was investigated using droplet digital polymerase chain reaction and showed a high variability among copepod individuals, underlining intra- and interspecific differences in copepod-associated prokaryotic communities. Overall, this work highlights that the guts of Temora sp. and Acartia sp. have the potential for methane production but are probably no hotspot.
