| evidence for a peak-shift in predator generalization among aposematic prey. | a previous theoretical model involving learning psychology and game theory has suggested how warning coloration in unprofitable prey could evolve and become stable. the model shows that in a dimension of increasing prey conspicuousness a displacement of the minimum in a predators' generalization gradient (peak-shift), can produce a strong enough selection pressure towards a more conspicuous coloration that would balance the increased risk of discovery and thus stabilize an aposematic strategy. u ... | 1996 | 8914330 |
