expectation that surviving trees have weathered severe drought, the
hydraulic deterioration demonstrated here reveals that surviving
regions of these forests are actually more vulnerable to future
droughts due to accumulated xylem [vascular] damage."<br>

young age and favorable competitive status in these forests, these

"The last few decades have brought warmer and wetter conditions
to the Adirondacks, which are typically good for plant growth,"
said Dr. Colin Beier, an associate professor of ecology at ESF who
supervised Bishop's thesis research. "Meanwhile, there have been
big strides in reducing acid rain, which is especially damaging to
sugar maple. Given these changes, we would expect these trees to be
thriving, but they are not."<br>
