Host specificity in phylogenetic and geographic space by Poulin, Robert, Krasnov, Boris R, Mouillot, David

“…The measurement of host specificity goes well beyond counting how many host species can successfully be used by a parasite. In particular, specificity can be…”

Parasitism alters three power laws of scaling in a metazoan community: Taylor’s law, density-mass allometry, and variance-mass allometry by Lagrue, Clément, Poulin, Robert, Cohen, Joel E.

“…Significance Power laws of scaling are major achievements of ecology. Such empirical laws say that one quantity varies as some power of another quantity. For…”
