Biologist addresses global diversity in mountain ecosystems
RELEASED: November 21, 2007
DANVILLE, KY—"One of the greatest issues of our time is the massive erosion of the variety of life in our landscapes locally and globally," writes Dr. Kerry Rabenold of Purdue University. Mountain ecosystems are particularly critical, he says, because individual populations often exist in microclimates created by elevation, or "altitudinal zones." Species that adapt to these altitudinal zones are often isolated and limited to a very small range, and as a result are particularly vulnerable to extinction.
