They found signs of increased drought stress in the low-elevation forests (1,650 to 4,000 feet), but not at high elevations (4,100 to 6,900 feet). Climate change appeared to affect both logged and unlogged forests at low elevations similarly.
原文章摘要擷取段落：
In lower montane forests, regardless of land-use history, we found multiple herb-community changes consistent with an effectively drier climate, including lower mean specific leaf area, lower relative cover by species of northern biogeographic affinity, and greater compositional resemblance to communities in southerly topographic positions.

[2010.10.31] 我還是把這個報導給留下了。但是因為無法獲取原文，所以暫時....目的是收集因氣候變遷，植物怎麼變？上次"看"成功大學地球科學系 劉正千教授的演講裡他提到日本杉木的因應方式，粗糙，但缺乏更詳實的資料，慢慢收了。
1. 主角是低海拔森林底層的草本植物。
2. 因氣候變遷，平均溫度較六十年前昇高了2度C。這使得低海拔森林有明顯的drought stress，是較低的葉面積、北方樹種較低的相對覆蓋度、與南部樹種有較大的組成相似性。
