Table 3 Network-level bipartite metrics and their definition
From: Plant–pollinator metanetworks in fragmented landscapes: a simulation study
Metric | Definition |
|---|---|
Connectance | The realized proportion of possible links |
Nestedness | Nestedness temperature of the matrix (0 means cold, i.e., high nestedness, 100 means hot, i.e., chaos) |
Interaction strength asymmetry (ISA) | The asymmetry in the interaction strength of two interacting species. Negative values indicate that the plants exert a stronger effect on pollinators |
Specialization asymmetry (SA) | Asymmetry (higher vs. lower trophic level) of specialization. Negative values show a higher specialization of the lower trophic level |
Linkage density | Marginal totals-weighted diversity of interactions per species (quantitative) |
H2 | H2 is a measure of specialization. H2 is between 0 and 1, with 1 indicating maximum specialization |
