Siberia interlayer edges

Description

Host-parasite temporal multilayer network. This data set contains the matrices of a temporal multilayer network representing the infection of 22 small mammalian host species by 56 ectoparasite species during 6 consecutive summers in Siberia (1982–1987).

Usage

data(siberia_interlayer)

Format

Edge list format (layer_from node_from layer_to node_to weight).

Details

The data set is in an matrix format.Each layer is a host-parasite bipartite network. Intralayer edges between a parasite species and a host species are the number of parasite individuals divided by the number of host individuals. Interlayer coupling edges connect each physical node to itself in the next layer (e.g., host A in layer 1 to host A in layer 2), and are calculated as the number of individuals in layer l+1 divided by the number of individuals in layer l. They therefore represent population dynamics. Interlayer edges only go one way (_l–>l+1_) because time flow one way.

See siberia_nodes for information about the nodes.
