【タイトル】
Gut microbiota composition of Japanese macaques associates with extent of human encroachment

【要旨】
Humans have become unavoidable part of most environments inhabited by wild animals nowadays. Noting the role of the gut microbiome in host, it is essential to understand how human-wildlife interactions and availability of anthropogenic food in habitats can affect an animal’s gut microbiome. This study therefore set out to examine the gut microbiota of Japanese macaques (Macaca fuscata) with varying accessibility to anthropogenic food and the possibility of using gut microbiota as indicator for macaques’ reliance on anthropogenic food. Using 16S rRNA gene sequencing, we described the microbial composition of Japanese macaques experiencing different types of human disturbance– captive, provisioned, crop-raiding and wild. We found gut microbiome composition sorted by level of anthropogenic food reliance of the macaques, reflecting macaques’ diet and associated functional need in different situations. We also identified potential bacterial taxa at different taxonomic ranks whose abundance potentially could help in assessing macaques’ accessibility to anthropogenic food. This study provided possible indices based on the gut microbiome profile in assessing macaques’ accessibility to/reliance on anthropogenic foods.
