Abstract excerpt
Phenotypic trade-offs, predicted to occur due to resource limitation, are not commonly detected. For this, the Y-model provides a powerful heuristic by showing that greater variation in resource acquisition than variation in allocation, masks trade-offs. However, the Y-model contains several other parameters beyond variation in acquisition and allocation, whose independent and interactive influences remain...
