Table 1 Topological properties of the abundant (relative abundance > 0.05%) and frequent ASVs (occurred in > 50% samples) co-occurrence networks and their identically sized Erdős-Rényi random networks in different habitats (river vs. lake)

From: Contrast diversity patterns and processes of microbial community assembly in a river-lake continuum across a catchment scale in northwestern China

  1. N: No. of nodes; E: No. of edges; avgCC: Average clustering coefficient; APL: Average path length; ND: network diameter; AD: Average degree; GD: Graph density; σ: small-word coefficient
  2. σ = (avgCC/avgCCr)/(APL/APLr) and σ > 1 indicates “small-world” properties, i.e., high interconnectivity and high efficiency [39]. Subscript r indicates the properties of the random network
