1  In water‐limited environments, the availability of water and nutrients to plants depends on environmental conditions, sizes and shapes of their root systems, and root competition. The goal of this study was to predict root system sizes and shapes for different plant growth forms using data on above‐ground plant sizes, climate and soil texture. 2  A new data set of > 1300 records of root system sizes for individual plants was collected from the literature for deserts, scrublands, grasslands…

It is demonstrated that general patterns of root morphology and plasticity are identifiable across diverse species and should enhance understanding of belowground strategy and performance across growth forms, but it will be critical to incorporate plasticity and additional aspects of root function into these efforts.

The main morphological features of the root system of the study species are related to their ability to sprout from their roots and form roots from their shoots, which might only be functionally viable in restricted root system morphologies and ecological strategies.

Overall, the results suggest that rooting depth systematically structures the ecology of savanna trees, and further work examining other anatomical and physiological root traits should be a priority for understanding savanna responses to changing climate and disturbances.
