The life strategy of bacteria rather than fungi shifts in karst tiankeng island-like systems.

ABSTRACT: Karst tiankeng is a typical terrestrial habitat island-like system, known as an oasis in a degraded karst landscape. However, we know little about the composition, structure, and life strategies of soil microbial communities in the karst tiankeng ecosystem. In this study, we use amplicon sequencing to investigate the soil bacteria and fungi of 26 karst tiankeng in two typical karst tiankeng groups. The results showed that the composition and structure of bacterial and fungal communities were significantly different at two dimensions (among and within the karst tiankeng group). Bacteria showed more sensitivity to variation in the karst tiankeng area and isolation than fungi. With the increase of karst tiankeng area and isolation, the bacterial life strategies shift from K-strategist
