Teng-Chiu Lin, J. Aaron Hogan and Chung-Te Chang discuss both the short and long term effects of cyclones on forest structure.     Cyclones damage individual trees, as shown in this image of Green Island (Taiwan) following Typhoon Tembin in 2012. These effects are linked to changes at the community and ecosystem level. Projected increases in cyclone frequency, intensity, and geographic distribution will remove tall trees of old-growth forests, and this removal will result in forest dwarfing.   (Photo: Dr. Si-Min Lin)

Subtropical wet life zone at the El Verde Field Station, Luquillo Experimental Forest, 74 days after Hurricane Maria in 2017. Remaining canopy trees are beginning to leaf out and woody debris and leaf litter still cover the forest floor. In an Overview article in this issue, J. Aaron Hogan and colleagues discuss a novel research framework for characterizing ecosystem responses to tropical cyclones.

利用植被指數進行地表綠度變化的監測是常見的分析，利用高時間解析度的遙測資料解析地表植被與不同時間尺度的氣候變異在國際間越來越受重視。本圖是以光合作用植物(PV, photosynthetic active vegetation)為基礎，利用TIMESAT物候分析軟體得到2001-2010年間生長季開始時間(onset)、生長季結束時間(offset)及生長季長度(length of the growing season)。以2002年為例，因為春季乾旱(2-3月雨量< 40公厘)的影響，明顯造成生長季延後及生長季長度縮短的結果。此分析方法有利於未來氣候變動或干擾的研究。
