Summary of different network types, describing the type of information flowing along edges and the consequences for weight transformation.

Network type	Edge weight	Proportionality to information flow	Requires transformation	Example references
Landscape	Cost-distance	Inverse	No	11,20
	Dispersal probability	Direct	Yes	10,44
	Dispersal time	Inverse	No	12
	Exchange of individuals	Direct	Yes	45
	Genetic similarity	Direct	Yes	46,47
Interaction	Frequencies	Direct	Yes	48,49
	Shared traits, affinity	Direct	Yes	50,51
	Trophic (or energy) flow	Direct	Yes	52,53

Landscape networks are spatially-explicit, while interaction networks depict relationships among entities. Social networks are here included as interaction networks, where shared traits include shared interacting organisms, foraging time, etc. depicting social relationships or common characteristics.
