Results of testing for functional signal in the flea-mammal interaction networks of four biogeographic realms (whether functionally similar species interact with similar partners). N number of flea species, number of host species, M the Mantel correlation between the functional distances and distances in the composition of either host spectra for fleas or flea assemblages for hosts
