Table 4 Hit rates in similarity-based graphs

Graph	Avg. hit rate	Edges	Relative density	Norm. hit rate
	R	\|E\|	\|E\|/n	(R·n)/\|E\|
Land use (Jaccard)	0.41607	210	0.29745	1.39878
Habitats (Jaccard)	0.44616	174	0.24646	1.81027
Species set (Jaccard)	0.47376	122	0.17280	2.74159
Land use (occurrences)	0.55524	277	0.39235	1.41517
Habitats (occurrences)	0.58591	278	0.39377	1.48795
Land use (areas)	0.40881	242	0.34278	1.19263
Habitats (areas)	0.50503	185	0.26204	1.92730

Since each graph has a different number of edges, a ratio of hit rates to relative density is also provided, where relative density is the ratio of edges in the similarity-based graph to edges in the raw-distance graph (n)
