New keys to keeping a diverse planet
Date:9/26/2007

Variation in plants and animals gives us a rich and robust assemblage of foods, medicines, industrial materials and recreation activities. But human activities are eliminating biological diversity at an unprecedented rate.

A new UC Davis study offers clues to how these losses relate to one another -- information that is essential as scientists and land managers strive to protect the remaining natural variation.

Sharon Strauss, a professor of evolution and ecology, and former doctoral student Richard Lankau (now a post-doctoral researcher at the University of Missouri-St. Louis and the University of Illinois), studied competition among genetically varied plants of one species (black mustard, Brassica nigra), and among black mustard and plants of other species.

"This is one of the first studies to show that genetic diversity and species diversity depend on each other," Lankau said. "Diversity within a species is necessary to maintain diversity among species, and at the same time, diversity among species is necessary to maintain diversity within a species.

"And if any one type is removed from the system, the cycle can break down, and the community becomes dominated by a single species."
