DURHAM, N.C. Younger, smaller trees that comprise much of North America s eastern forests have increased their seed production under climate change, but older, larger trees that dominate forests in much of the West have been less responsive, a new Duke University-led study finds.
Declines in these trees seed production, or fecundity, could limit western forests ability to regenerate following the large-scale diebacks linked to rising temperatures and intensifying droughts that are now occurring in many states and provinces. ....
