Holling's disc equation
NettetBecause Holling used an empirical approach he did not actually derive the equation; rather, he fit an equation to his data. derive the disk equation by starting with a simpler formulation: RATE = Energy gained in foraing/(time searching + time handling) put into symbols, this equation reads: R = Ef/(Ts + Th) Nettet6. apr. 2024 · Holling's disc equation Quick Reference A method for calculating the functional response of predators to increased prey density.

Nettet10. jul. 2013 · Holling's disc equation assumes that at high food densities, the feeding rate is limited by the handling time of the individual rather than the time taken to locate food (Baker et al. 2010). Whilst this appeared true in the roach of this study, other studies have shown this is not always apparent.
