Tree Diversity in Relation to Tree Height: Alternative Perspectives
Givnish TJ. 2017. Tree Diversity in Relation to Tree Height: Alternative Perspectives. Ecology Letters. 20:395-397
ABSTRACT: Marks et al. (Ecol. Lett., 19, 2016, 743–751) show that tree diversity increases with tree height in North America and argue it reflects habitat ‘suitability’. This finding conflicts with classical results, lacks controls for covariates of tree height, and can be explained alternatively using the modified Janzen–Connell effect and regional variance in habitats.
