Eothenomys miletus(E.miletus)is one of the rodent species found in Yunnan,and it has caused significant harm to local agricultural production.In this study,we aimed to investigate the differences in feeding habits and stomach fungi of E.miletus across different areas in the Hengduan mountain regions.By exploring the main factors affecting the feeding habits and fungi of E.miletus,this study provides a theoretical basis for the prevention and control of this species.We collected E.miletus specimens from five regions,namely Deqin,Xianggelila,Lijiang,Jianchuan,and Ailaoshan.We measured their feeding habits and the types of fungi in their stomachs using high-throughput sequencing technology.The results showed that E.miletus primarily fed on Poaceae,Oxalidaceae,Asteraceae,and Fabaceae.Food diversity of E.miletus in Ailaoshan and Jianchuan was significantly lower than in the other three regions.As for stomach fungi,Ascomycota and Basidiomycota were the absolute dominant sectors.Changes in the diversity of fungi in different regions were consistent with changes in food diversity.The diversity of fungi in Ailaoshan and Jianchuan regions was lower than in the other three regions.These findings suggest that the feeding habits of E.miletus in different regions were affected by plant species,which,in turn,affects the diversity of fungi in their stomachs. 展开更多

In order to explore how the sympatric species of Eothenomys olitor,Apodemus chevrieri,Eothenomys miletus will adjust their thermogenic capacity to adapt to the environment under the background of global warming,as well as which species has stronger high-temperature adaptation ability.Body mass,liver and brown adipose tissue(BAT)mass and their protein contents under high-temperature conditions(30±1°C,acclimation for 28 days)were measured in the present study.The results showed that all three kinds of animals in the warm acclimation group increased body mass and reduced thermogenic capacity,in which the indicators of thermogenesis for E.olitor had the smallest change range,and there were significant differences in body mass and thermogenic capacity among the three species.All of the above results suggested that the three sympatric rodents chosen to increase their body mass,reduced thermogenesis and energy consumption to adapt to the environment under high temperature conditions,which showed a phenomenon of convergent adaptation.Moreover,the change amplitude of the E.olitor was the smallest,indicating that high temperature has the least impact on its survival,indicating that E.olitor may had stronger adaptability under the conditions of global warming. 展开更多
