SRP327729 PRJNA744022 rumen fungal diversity of high plateau ruminants Previous studies showed that the yak (Bos grunniens) rumen microbiome and fermentation differ from those of other ruminants, but there is limited knowledge of the features of the rumen microbiome that make yak adapted to its unique environmental and dietary conditions. Here we investigated the rumen fungal to understand how yak adapts to the coarse forage and harsh environment in the high Qinghai-Tibetan plateau.
