Pairwise spatial associations
The pairwise spatial associations assessed bygij (r ) indicate that interspecific spatial
independence (-1.96 ≤ z (r ) ≤ 1.96) was the dominant
pattern across the three different spatial scales (accounting for
82.09%, 83.05% and 85.30%, respectively) (Table 1). There were 315,
375 and 346 repulsion cases (z (r ) < -1.96) out
of the 6320 pairs (accounting for 4.98%, 5.93% and 5.47%) at the
spatial scales of 5, 30 and 50 m, respectively. Attraction was more
commonly observed with 817, 696 and 583 cases (z (r )
> 1.96) (accounting for 12.93% 11.01% and 9.22%) than
repulsion cases at the three scales. The same trends were also found in
the spatial association evaluated by the summary statistic ofDij (r ), in which, spatial independence was
also the dominating pattern between species (Table 1).
