ABSTRACT

Simple Summary Rodents are important components of ecosystems with diverse ecological functions, both maintaining biodiversity and potentially causing disaster. Plants provide food and shelter for rodents and are closely associated with rodent community succession. Exploring the mechanisms of rodent community evolution is the theoretical basis for rodent integrative management. The study explored the relationship between vegetation cover and rodent community characteristics in Dongting Lake, China, based on long time series data. The study confirmed the significant spatial and temporal variability of rodent communities in the Dongting Lake area and the correlation with vegetation cover. The results of the study showed that there was a significant correlation between the fatness of Microtus fortis and low and medium levels of vegetation cover, while the relationship between the fatness of Apodemus agrarius and vegetation cover is the opposite. The study suggests that we should continue to further strengthen the long-term monitoring of rodent communities and vegetation communities in the Dongting Lake area. This study is the first time the relationship between rodent communities and vegetation cover in the Dongting Lake area has been monitored over a long period of time, which provides a reference for clarifying the patterns of animal succession and plant succession, and also provides a basis for wildlife management in the area.
