Experimental manipulation of predation risk distribution at three different treatments in a 60 foraging experiment with 20 voles, Treatments: SRU safe, risk-uniform; RH risk-heterogeneity, RRU risky, risk-uniformity.

Assumptions, predictions and results, in fat print the treatment differing from the two others. GUD: giving-up-density of food left in the patch (mean +− standart deviation). Different small letters indicate significant difference among treatments in paired post-hoc comparisons, difference between b and (b): p
