The study shows that species that often occur together now are projected to shift in very different ways, resulting in new ecological communities. These novel (or "no-analog") communities may disrupt complex webs of plant and animal interactions, with unanticipated consequences for species and ecosystems.

"Some species, such as warblers, which can weigh less than an ounce but fly 2,500 miles without resting, double their body weights in preparation for the voyage.To put it in a human perspective, if you were going to put on a lot of fat and try to live off it while doing a cross-country run, you would die," said Russell Greenberg, head of the National Zoo's Migratory Bird Center.

The Environmental Literacy Council has been dedicated to helping teachers, students, policymakers, and the public find cross-disciplinary resources on the environment. An independent, 501(c)3 organization, the Council offers free background information on common environmental science concepts; vetted resources to broaden understanding; and curricular materials that don't tell teachers how to teach, but give them the tools to augment their own backgrounds - no matter what their current knowledge.
