Host-genotype dependent gut microbiota drives zooplankton tolerance to toxic cyanobacteria

Abstract

Variations in the gut microbiota may affect the host’s performance in changing environments. Here, Macke et al. show, in the freshwater crustacean Daphnia magna, that host genotype and external microbial inoculum interact to shape the gut microbiota, which in turns mediates tolerance to toxic cyanobacteria.
