Abstract

There is a need among botanists to include the costs and benefits of clonal plant growth into their foraging models. The present commentary focuses on some conceptional points of the possible applicability of existing optimality models to plants and points out the differences between traditional non-optimal and initial optimal plant foraging models. The assumptions and predictions of the marginal value theorem are discussed through a comparison of animals and plants. Listing the difficulties of interpreting these assumptions for plants highlights that direct applicability of the model is limited, but by giving a different interpretation to the decision variable and the gain function the model can describe the "foraging behaviour' of the model plant only in a simplistic environment. -Author
