    Notes: Abstract A generalized descriptive equation for the effect of prey density on the instantaneous rate of attack was proposed; $$A(N_0 ) = \frac{{T_t }}{{t_h + 1/\left[ {a'N_0 \exp (cN_0 )} \right]}}$$ whereA(N o ) is the number of attacks per predator during timeT t ,N o is the prey density,T t is the total time the prey was exposed,T h is the handling time per prey,a′ is the rate of successful search, andc is the facilitation coefficient. The proposed equation can describe all types of the functional response curves; withc=a′ t h (pseudo Type I), withc=0 (Type II), withc〉a′ t h (Type III), and withc〈0 (Type IV). The applicability of the equation was tested against the results of a simulation model and available laboratory and field data on predation. The equation described these data very well and in many cases yielded biologically interesting insights, although the equation was proposed primarily for descriptive purposes.
