Independent evolution of leaf and root traits within and among temperate grassland plant communities
Download2011-01-01
In this study, we used data from temperate grassland plant communities in Alberta, Canada to test two longstanding hypotheses in ecology: 1) that there has been correlated evolution of the leaves and roots of plants due to selection for an integrated whole-plant resource uptake strategy, and 2)...

Plant Phenotypic Plasticity Belowground: A Phylogenetic Perspective on Root Foraging Trade‐Offs
Download2005
Cahill Jr, J. F., Kembel, S. W.
Many plants proliferate roots in nutrient patches, presumably increasing nutrient uptake and plant fitness. Nutrient heterogeneity has been hypothesized to maintain community diversity because of a trade‐off between the spatial extent over which plants forage (foraging scale) and their ability to...
