Figure 1. Spatial and social assortment . a , Palmyra
Atoll Marine Reserve (red diamond) in the Central Pacific Ocean.b , Space use measured as the 50% utilisation distribution (UD)
of sharks assigned to their respective colonies which were defined using
community detection of individual movement networks (colours reflect
colony groups in c ). c , Social networks and the
distribution of weighted assortativity coefficients (\(r_{d}^{w}\)) for
10,000 random networks (boxes) and observed networks (red circles)
across four years of shark telemetry data. Each node in the network
represents an individual shark, with clusters showing closely associated
dyadic pairs. Networks were all significantly, positively assorted by
colonies, represented as different coloured nodes. No assortment is
illustrated by blue dashed line. (p < 0.05*, p< 0.01** and p < 0.001***).
