Abstract: Temperature is an important non-biological environmental variable that drives the adaptive trajectory of animal lineages and the composition of animal communities. Ambient temperature, as one of the many factors affecting the changes of intestinal microbiota, can affect the composition and abundance of gut microbiota, and thereby regulate the biological process and functions of the host growth, development, reproduction and immunity. The composition of gut microbiota and its metabolites vary significantly at different temperatures, which have been reported in monogastric animals, ruminants and so on. Extreme temperature can affect host phenotypes mainly by inducing structural and functional differences in intestinal microbiota. At present, the understanding about how temperature affects the intestinal flora of animals is still very limited. In this paper, the differences in the structure and function of intestinal microbiota under different ambient temperatures were summarized and reviewed. Further discussion and exploration of the relationship between the gut microbiota and host adaptation mechanisms caused by ambient temperature, including the effects on mechanisms of heat production, digestive system and immune system of host, will provide references and ideas for the regulation of intestinal microflora on host health.

Key words: ambient temperature, intestinal microflora, immune system, adaptation mechanism
