      abstract     = {Whether the fraction of total forest biomass distributed in
                      roots, stems, or leaves varies systematically across
                      geographic gradients remains unknown despite its importance
                      for understanding forest ecology and modeling global carbon
                      cycles. It has been hypothesized that plants should maintain
                      proportionally more biomass in the organ that acquires the
                      most limiting resource. Accordingly, we hypothesize greater
                      biomass distribution in roots and less in stems and foliage
                      in increasingly arid climates and in colder environments at
                      high latitudes. Such a strategy would increase uptake of
                      soil water in dry conditions and of soil nutrients in cold
                      soils, where they are at low supply and are less mobile. We
                      use a large global biomass dataset (>6,200 forests from 61
                      countries, across a 40 °C gradient in mean annual
                      temperature) to address these questions. Climate metrics
                      involving temperature were better predictors of biomass
                      partitioning than those involving moisture availability,
                      because, surprisingly, fractional distribution of biomass to
                      roots or foliage was unrelated to aridity. In contrast, in
                      increasingly cold climates, the proportion of total forest
                      biomass in roots was greater and in foliage was smaller for
                      both angiosperm and gymnosperm forests. These findings
                      support hypotheses about adaptive strategies of forest trees
                      to temperature and provide biogeographically explicit
                      relationships to improve ecosystem and earth system models.
                      They also will allow, for the first time to our knowledge,
                      representations of root carbon pools that consider
                      biogeographic differences, which are useful for quantifying
                      whole-ecosystem carbon stocks and cycles and for assessing
                      the impact of climate change on forest carbon dynamics.},
