Titre : Scientists map geographic patterns of soil microbe communities in Hexi Corridor deserts

Based on field survey and next-generation sequencing, the researchers mapped soil microbial geographic diversity patterns in the Hexi Corridor deserts to further determine the main driving factors responsible for shaping the soil microbial community.

Présentation
The researchers found that bacteria and eukaryotic diversity increased linearly with increasing longitude and altitude, but decreased with increasing latitude in the Hexi Corridor deserts, whereas archaeal diversity showed little change along these geographic gradients. The research results showed that soil microbial community composition in the Hexi Corridor was shaped by geographic distance and environmental variables, among which geographic distance was slightly more important than the environmental variables.

Besides, this study also suggested that the archaea were the core groups for building this region’s soil microbial co-occurrence network.
This study deepens our understanding of the roles of biogeochemical processes in shaping microbial diversity. It also provides clues for developing better management strategies in response to accelerating climate change.
