Seasonal diets supersede host species in shaping the distal gut microbiota of Yaks and Tibetan sheep

Abstract Yaks and Tibetan sheep are important and renowned livestock of the Qinghai-Tibetan Plateau (QTP). Both host genetics and environmental factors can shape the composition of gut microbiota, however, there is still no consensus on which is the more dominant factor. To investigate the influence...
