Simulation of the evolution of root water foraging strategies in dry and shallow soils.

ABSTRACT:

Background and aims

The dynamic structural development of plants can be seen as a strategy for exploiting the limited resources available within their environment, and we would expect that evolution would lead to efficient strategies that reduce costs while maximizing resource acquisition. In particular, perennial species endemic to habitats with shallow soils in seasonally dry environments have been shown to have a specialized root system morphology that may enhance access to water resources in the underlying rock. This study aimed to explore these hypotheses by applying evolutionary algorithms to a functional-structural root growth model.

Methods

A simulation model of a plant's root system was developed, which represents the dynamics of water uptake and structural growth.
