A Virginia Tech scientist has discovered a potentially new form of plant communication, one that allows them to share an extraordinary amount of genetic information with one another. The finding by Jim Westwood, a professor of plant pathology, physiology, and weed science in the College of Agriculture and Life Sciences, throws open the door to a new arena of science that explores how plants communicate with each other on a molecular level. It also gives scientists new insight into ways to fight parasitic weeds that wreak havoc on food crops in some of the poorest parts of the world.

The U.S. Fish and Wildlife Service today proposed to protect more than a half-million acres of critical habitat across the West for the yellow-billed cuckoo, a songbird that lives along rivers and streams. The bird was proposed for Endangered Species Act protection in October 2013 as part of a 2011 agreement with the Center for Biological Diversity to speed protection decisions for 757 imperiled species nationwide. Today’s proposal would protect 546,335 acres of streamside habitat in nine western states including Arizona, California, Colorado, Idaho, Nevada, New Mexico, Texas, Utah and Wyoming.
"This is an important victory not just for yellow-billed cuckoos but for rivers and streams across the West," said Michael Robinson, a conservation advocate at the Center, which first petitioned for the cuckoo’s protection in 1998.
