Assumptions Central place foraging

-


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.



individuals attempt maximize rate of delivery per round trip * packages have @ least 2 components different utilities
the optimal load size less or equal resources available
time spent away camp comes opportunity cost, time spent in camp not. there no cost processing in camp.
