Experiments investigating effects of temperature on the composition of animal gut microbiomes. (A) Phylogenetic tree of animal species in which the effects of ambient temperature on the composition of the gut microbiota have been examined by experimental manipulations. Scale bar indicates divergence time in millions of years (MY). (B) Boxes correspond to host species at tips of phylogeny in (A) and contain lines indicating the relationships observed between temperature and the relative abundances of Firmicutes and Proteobacteria, two predominant gut bacterial phyla that display consistent trends across animal taxa. Upward and downward sloping lines indicate positive and negative associations within temperature, respectively. Dashed lines indicate instances in which temperature displayed consistent associations with relative abundances of genera within either Firmicutes or Proteobacteria.
