“…Interestingly, previous research on fish reported a greater richness of microbiome composition under warmer temperatures, potentially attributed to selective pressure ( Kokou et al, 2018 ). Furthermore, an increase in microbial diversity and richness with temperature increases has been reported in Rana chensinensis tadpoles, possibly due to a higher prevalence of pathogenic taxa ( Niu et al, 2022 ). In our study, we observed significantly higher community richness of the gut microbiota in crocodile lizards at 28°C and 30°C than at 22°C.…”

The gut microbiota plays an essential role in maintaining the health and fitness of the host organism. As a critical environmental variable, temperature exerts significant effects on animal survival and reproduction. Elevated temperatures can influence the composition and function of the animal gut microbiota, which may have potentially detrimental effects on the host. The crocodile lizard (Shinisaurus crocodilurus) is an ancient and currently endangered reptile species due to human hunting and habitat destruction. Given the predicted shifts in global temperatures in the next century, it is important to understand how warming affects the gut microbiota of these vulnerable lizards, which remains unclear. To determine how the microbial communities change in crocodile lizards in response to warming, we analyzed the gut microbiota under five temperature conditions (22°C, 24°C, 26°C, 28°C, and 30°C) using 16S rRNA high-throughput sequencing. Results showed that the dominant phyla, Proteobacteria and Bacteroidetes, in gut microbiota were not significantly affected by temperature variations, but increasing temperature altered the structure and increased the community richness of the gut microbiota. In addition, warming changed the abundance of Pseudomonas aeruginosa and Actinobacteria, which may have negative effects on the physiological health of the crocodile lizards. Functional prediction analysis demonstrated that the functional pathways enriched in crocodile lizards were mainly related to metabolism, with no significant differences observed in these pathways at KEGG pathway level 1 after warming. These results provide valuable insights into the ecological adaptations and regulatory mechanisms employed by crocodile lizards in response to warming, which may be of benefit for their conservation.

“…However, some specific bacteria, such as Brucella and Lactobacillus, increased their relative abundance at 23°C and 37°C, but not at 5°C. The gut microflora was not only sensitive to environmental temperature, but also showed seasonal physiological plasticity in energy intake, resting metabolic rate (RMR), non-shivering thermogenesis (NST) [63] , and modifications of the intestinal immune system [64][65][66][67] . These results suggest that external environmental changes can affect the adaptability of intestinal microorganisms, which can further enhance the adaptability to the environment.…”

The gut microflora is a combination of all microbes in intestine and their microenvironment, and its change can sensitively reflect the relevant response of the body to external environment and remarkably affect body's metabolism as well. Recent studies have found that cold exposure affects the body's gut microflora, which can lead to changes in the body's metabolism of glucose and lipid. This review summarizes recent research on the effects of cold exposure on gut microbes and metabolism of glucose and lipid, aiming to provide some new ideas on the approaches and measures for the prevention and treatment of diabetes and obesity.

Many amphibian behaviors and physiological functions adapt to daily environmental changes through variations in circadian rhythms. However, these adaptations have yet to be reported in Dybowski’s frog (Rana dybowskii). We aimed to elucidate the dynamic changes in the behavior and gut microbiota of R. dybowskii within a 24 h cycle during their migration to hibernation sites. Thus, we monitored their behavior at 4 h intervals and collected samples for microbiome analysis. We found that the juvenile frogs arrived at hibernation sites earlier than the adults. Among the adults, the male frogs arrived earlier. The richness and diversity of the gut microbiota in the adult R. dybowskii were lowest at 14:00. At 6:00, the differences between the males and females were most significant. At 18:00, there was an increase in the activity of Bacteroides, Coprobacillus, Ruminococcus, and Dorea in the intestinal tracts of the male frogs, whereas in the intestinal tract of the female frogs, there was an increase in the activity of Pseudoramibacter_Eubacterium, Desulfovibrio, Anaerotruncus, and PW3. This indicated diurnal rhythmic variations in the gut microbiota and significant sex-based differences in the microbial activity at different time points. Our findings contribute to the understanding of the circadian rhythm of R. dybowskii and provide crucial insights into improving breeding strategies.
