FLAGSTAFF, Arizona, June 25 (TNSJou) -- Northern Arizona University issued the following news:
Drought--even in a single year--can leave aspen more vulnerable to insect infestation and other stressors decades later, a new study by NAU researchers found. Aspen trees that were not resilient to drought stayed smaller than others, growing more slowly and succumbing to an outbreak of insects known as aspen leaf miners that have plagued interior Alaska for more than two decades.
