R co-occurrence network
WebIt has also been suggested that co-occurrence may be a result of dispersal limitation ( Ulrich, 2004 ), or common selection due to specific environmental factors, without any actual direct or indirect interaction ( Peres-Neto et al., 2001; Freilich et al., 2024 ). We believe that this latter explanation is in many cases driving the topology of ...
