Fungal disease and temperature alter skin microbiome structure in an experimental salamander system

Pathogens compete with host microbiomes for space and resources. Their shared environment impacts pathogen–microbiome–host interactions, which can lead to variation in disease outcome. The skin microbiome of red‐backed salamanders ( Plethodon cinereus ) can reduce infection by the pathogen Batrachochytrium dendrobatidis (Bd) at moderate infection loads, with high species richness and high abundance of competitors as putative mechanisms. However,...
