Appendix A. Sample size and network size for each year from 1998 to 2011.

Table A1. Annual parameters for a network of cavity-nesting birds and mammals, from 1998 to 2011, and for all years combined. Richness of cavity producers is the number of excavator species + natural decay that contributed to the network in a given year (i.e., they produced the cavities that were used by secondary cavity-nesters that year). Richness of secondary cavity-nesters is the number of secondary cavity-nesting species that nested (in cavities with a known producer) that year. Each interaction is one nest of a secondary cavity-nesting species in a cavity with known producer. Each link is one unique interaction between a cavity producing species (or natural decay) and a secondary cavity-nesting species.
