-


transport decay curves demonstrate reduction in return rates (cal/hour) experienced central place forager function of round trip travel time. travel threshold field processing models,




z

j




{\displaystyle z_{j}}

represents travel time @ processing next stage provide higher return rates, indicated intersection of decay curves 2 sequential stages of processing. shaded areas represent optimal extent of processing travel time increases.


this model rests on number of assumptions. important listed here.
