Future of Many North American Crops May Depend on Ground Beetles Response to Climate Change

A new study by researchers at Penn State University, Duke University, and the University of Saskatchewan suggests not all of the nearly 2,000 species of ground beetles found in North America will thrive under climate change. Some could decline. And that could have far-reaching implications for agriculture, forestry, and conservation.

Climate impacts drive east-west divide in forest seed production

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.
