Gut microflora may facilitate adaptation to anthropic habitat: A comparative study in Rattus.

摘要: Anthropophilic species ("commensal" species) that are completely dependent upon anthropic habitats experience different selective pressures particularly in terms of food than their noncommensal counterparts. Using a next-generation sequencing approach, we characterized and compared the gut microflora community 53 commensal Rattus rattus 59 satarae captured 10 locations Western Ghats, India. We observed that, while identity was important characterizing communities two hosts, environmental factors also had significant effect. While there geographic variation R. satarae, no effect distance on R. rattus. Interestingly, host genetic did not significantly influence either hosts. Collectively, these results indicate shift habitat is likely to result change imply complex trait, influenced by various parameters habitats.
