Daniel Laughlin, an associate professor in the UW Department of Botany and director of the Global Vegetation Project, led the study, which included researchers from the German Centre for Integrative Biodiversity Research in Leipzig, Germany; Leipzig University; and Wageningen University & Research in Wageningen, Netherlands.

Instead, a diversity of root traits occurred in warm or wet climates.
