Dual-Domain Primary Succession of Bacteria in Glacier Forefield Streams and Soils of a Maritime and Continental Glacier.

ABSTRACT: Glaciers retreat rapidly and create newly exposed terrestrial and aquatic habitats in glacier forefields, where primary succession proceeds synchronously in glacier forefields. Here, we introduced the "Dual-Domain Primary Succession" concept to examine the parallel yet distinct primary succession processes in soil and stream ecosystems within glacier forefields, by focusing on Hailuogou Glacier and Urumqi Glacier No.1 in China. Findings showed that soil bacterial communities exhibited higher α-diversity with a decreasing pattern in Hailuogou Glacier, in contrast to Urumqi Glacier No.1, which displayed lower and unimodally distributed α-diversity along the glacier forefield chronosequence (GFC). A similar pattern emerged in streams, except for an increasing α-diversity trend in Urumqi Glaci
