From: The gut microbiome mediates adaptation to scarce food in Coleoptera
The sampled cave species and sites in the Carpathian Mountains. Caves from where representatives of Coleoptera were analyzed for the gut microbiome are shown within the climatic zonation and influences (modified after [16]). The mandibles of a representative detritivore ((Drimeotus (Fericeus) kraatzi)) and of the two Duvalius species are also shown
