5.4 Utilization distribution overlap index

UDOI − an UD overlap index similar to Hurlbert index of niche overlap that assumes they use space independently of one another (Hurlbert 1978). Values range from zero (no overlap) to 1 (uniformly distributed and have 100% overlap) but can be >1 if both UDs are nonuniformly distributed and have a high degree of overlap.
