Figure 8.4
Functional (top) and numerical (bottom) responses for wolves preying on moose.
Messier (1994) fit Michaelis-Menton equations (type II) to these data from 27 wolf/moose studies.
Sparsity of data make distinction between a type II and a type III (logistic) response impossible to
assess. The product of the functional and numerical responses yields the total moose killed, which
when divided by moose density gives the predation rate. From Messier (1995).
