摘要： Grasslands are vital ecosystems that play a crucial role in providing numerous services to both humans and the environment. Healthy grasslands are characterized by diverse vegetation, efficient soil, and abundant microbial communities, which enable them to function effectively. However, these ecosystems are at risk of degradation due to various factors, such as overgrazing, land conversion for agriculture, climate change, and rodent activities. Rodents, in particular, are known to have a significant impact on grassland ecosystems. Moderate and low rodent density can be beneficial for grassland dynamics by acting as ecological engineers, and playing a role in the food chain, while heavy rodent density and outbreaks can have detrimental effects. The rodent's activities are associated with and influenced by other driving factors of grassland degradation. Depending on their density and habitat, rodents can have either beneficial or detrimental effects on the dynamics of grasslands by altering the microbial communities, edaphic factors, and vegetation. This review focuses on rodent activities as one of the potential drivers of grassland degradation on vegetation, soil physicochemical dynamics, and microbial communities. This work also deciphers the interplay between rodent activities and other driving factors of grassland degradation. It also discusses potential strategies for mitigating the impact of rodent disturbance on degraded grasslands. Additionally, suggestions for future research directions are provided to explore the role of rodent activities in shaping the structure and functions of grassland ecosystems. The exact influence of rodent activities on grasslands is still not fully understood, and further manipulative research is needed to determine its impact on grassland dynamics.
