Biogeographic distribution of autotrophic bacteria was more affected by precipitation than by soil properties in an arid area.

ABSTRACT:

Introduction

Autotrophic bacteria play an important role in carbon dioxide fixation and are widespread in terrestrial ecosystems. However, the biogeographic patterns of autotrophic bacteria and the driving factors still remain poorly understood.

Methods

Herein, we conducted a 391-km north to south transect (mean annual precipitation <600 mm) survey in the Loess Plateau of China, to investigate the biogeographic distributions of autotrophic bacteria (RubisCO cbbL and cbbM genes) and the environmental drivers across different latitude sites with clear vegetational and climatic gradients.

Results and discussion

The soils in northern region with lower precipitation are dominated by grassland/forest, which is typically separated from the soils in southern reg
