Figure 3 . a) Distribution of in- and out-degree for all premises. b) Distribution of the number of animals moved per premises. Both axes are on a base10 logarithmic scale in both panels.
Edge-loyalty ( \(\theta\)) and node-loyalty ( \(\varphi\)) of the network
The union and intersection of the edges and nodes were calculated between consecutive years. Loyalty was far lower from 2016-17 than from 2015-16, even though more than 79% of nodes remained active across the years (Table 4).
