Tibetan sheep grazing modifies rodent density and their interactions effect on GHG emissions of alpine meadow.

ABSTRACT: Digging and mound-building by rodents lead to considerable disturbances in the topsoil and may affect plant composition, soil properties. However, little is known about the effects of these activities on GHG emissions, especially under different grazing management. This paper aimed to measure changes in CO₂ and CH₄ efflux with varying grazing management during the warm and cold seasons and to relate CO₂ and CH₄ efflux to pika burrow density and zokor mound density with different grazing management. Results of this study showed that CO₂ efflux was significantly affected by the grazing season, whereas CH₄ efflux was significantly affected by the grazing system. There were significant relationships between GHG efflux and rodent
