Overview

Analysis reveals hydrological connectivity significantly influences microbial community structure and diversity.

Key Points

  • Higher bacterial alpha diversity is observed under increased hydrological connectivity, indicating changing microbial dynamics.
  • As hydrological connectivity increases, the community assembly becomes more stochastic, accounting for approximately 80% of patterns.
  • Bacterial communities exhibit greater environmental heterogeneity under low hydrological connectivity levels and robust network interactions.
  • Stochastic processes dominate assembly mechanisms over environmental factors and biotic interactions, highlighting ecological influences.
