Microbiome-assisted carrion preservation aids larval development in a burying beetle.

ABSTRACT: The ability to feed on a wide range of diets has enabled insects to diversify and colonize specialized niches. Carrion, for example, is highly susceptible to microbial decomposers, but is kept palatable several days after an animal's death by carrion-feeding insects. Here we show that the burying beetle Nicrophorus vespilloides preserves carrion by preventing the microbial succession associated with carrion decomposition, thus ensuring a high-quality resource for their developing larvae. Beetle-tended carcasses showed no signs of degradation and hosted a microbial community containing the beetles' gut microbiota, including the yeast Yarrowia In contrast, untended carcasses showed visual and olfactory signs of putrefaction, and their microbial community consisted of endogenous
