Pedogenesis and plant diversity

posted Feb 20, 2013, 8:10 PM by Etienne Laliberté
We wrote a review that presents different hypotheses to explain why older, more strongly-weathered soils generally show greater plant diversity. This review has just been accepted in Trends in Ecology and Evolution. In our paper, we propose that long-term soil chronosequences will be excellent 'natural experiments' to further advance our understanding of belowground controls over plant diversity, and suggesting a methodological approaches that should allow us to evaluate the relative importance of different factors.
