為了解決Tundra ecosystem 的問題，作者Lee, Yoo Kyung 這樣論述：
The Arctic is a special world. The Arctic Ocean is covered by white sea ice, and its margins are surrounded by bare terrestrial regions, known as tundra. Tundra is a cold and dry environment without trees, but even in the absence of trees, tundra plants such as dwarf shrubs, grasses, herbs and moss
support the harsh environment by providing sustenance and shelter. This book introduces representative arctic plants and their function in Svalbard, revealing the unique tundra ecosystem, and discussing the direct and indirect effects of climate change in the Arctic. Yoo Kyung Lee is a polar scien
tist. She majored in botany and completed her Ph.D. at Seoul National University. She is currently investigating the ecological succession on the land exposed by the disappearance of glaciers disappear in Svalbard. Wanting to share the wonder of Arctic plants with a wider audience, she published ＂Be
autiful Arctic Tundra Plants＂ with colleagues, and ＂Handbook of Svalbard Plants＂ with Arve Elvebakk. Yoo Kyung Lee is a Principal Research Scientist at the Korea Polar Research Institute. She is also a member of the Arctic Monitoring and Assessment Programme of Arctic Council and Sustaining Arctic O

探討生態系環境因素與生物特徵連結策略對學生生態系概念學習之影響
為了解決Tundra ecosystem 的問題，作者楊誠晅 這樣論述：
本研究探討連結生態系環境因素與生物特徵對大學以上學生學習生態系相 關內容之影響。研究過程中，受試者需進行先備知識檢測、連結任務、引導教學與分類任務，並在過程中不斷思考生物特徵與生態系環境因素之間的連結。30 位受試者在先備知識檢測與特徵紀錄筆記中推理生物特徵與生態系環境因素之間的連結並發想沙漠、雨林、凍原生態系的生物特徵;在分類任務中，提供受試 者一對生物的特徵，希望受試者以特徵與生態系環境因素連結作為分類依據，將生物分類至適合生存的生態系。資料分析中以受試者「對生物特徵與生態系環境 因素連結的掌握程度」作為主軸，對先備知識檢測、分類任務與特徵紀錄筆記進行評分，將受試者的回答先依照有無推理做
區分，再依照推理是否合理給予 3 分或 2 分;若受試者僅能依照印象或先備知識說出生物特徵而無推理則得 1 分; 無回答或回答錯誤則得 0 分。研究結果顯示，整體受試者在先備知識檢測時的回答多集中於無推理的 1 分，而經過連結任務與引導教學後，分類任務回答與統整筆記得分分佈則集中於 3 分。顯示經過本研究設計的教學後，多數受試者都能從只能說出生物特徵無法 推理連結，進步到不僅能說出特徵也能成功推理出特徵與生態系環境因素間的連 結。另外分析分類任務中，錯誤分類生態系的受試者，這些受試者雖然能夠推理出合理的特徵與生態系環境因素連結，但因為生物相關知識不足以及無法考慮整 體生態系對同一生物不同特徵的
影響，因此造成受試者即使推理出合理連結，依舊錯誤分類生態系。
Extreme Conservation: Life at the Edges of the World
為了解決Tundra ecosystem 的問題，作者Berger, Joel 這樣論述：
"Extraordinary. . . . Berger is a hero of biology who deserves the highest honors that science can bestow."--Tim Flannery, New York Review of Books On the Tibetan Plateau, there are wild yaks with blood cells thinner than those of horses' by half, enabling the endangered yaks to survive at 40 bel
ow zero and in the lowest oxygen levels of the mountaintops. But climate change is causing the snow patterns here to shift, and with the snows, the entire ecosystem. Food and water are vaporizing in this warming environment, and these beasts of ice and thin air are extraordinarily ill-equipped for t
he change. A journey into some of the most forbidding landscapes on earth, Joel Berger's Extreme Conservation is an eye-opening, steely look at what it takes for animals like these to live at the edges of existence. But more than this, it is a revealing exploration of how climate change and people a
re affecting even the most far-flung niches of our planet. Berger's quest to understand these creatures' struggles takes him to some of the most remote corners and peaks of the globe: across Arctic tundra and the frozen Chukchi Sea to study muskoxen, into the Bhutanese Himalayas to follow the rarely
sighted takin, and through the Gobi Desert to track the proboscis-swinging saiga. Known as much for his rigorous, scientific methods of developing solutions to conservation challenges as for his penchant for donning moose and polar bear costumes to understand the mindsets of his subjects more close
ly, Berger is a guide par excellence. He is a scientist and storyteller who has made his life working with desert nomads, in zones that typically require Sherpas and oxygen canisters. Recounting animals as charismatic as their landscapes are extreme, Berger's unforgettable tale carries us with humor
and expertise to the ends of the earth and back. But as his adventures show, the more adapted a species has become to its particular ecological niche, the more devastating climate change can be. Life at the extremes is more challenging than ever, and the need for action, for solutions, has never be
en greater.
循環統計應用於開花物候分析：以雪山圈谷為例
為了解決Tundra ecosystem 的問題，作者林亞頎 這樣論述：
高山生態系在全球暖化之下面臨較高風險，尤其開花物候受到影響產生明顯波動。雪山地區作為臺灣高山生態系研究熱點，雪東線步道累積10年開花物候資料，本研究延續前人調查，並透過循環統計分析雪山圈谷開花物候 (2012.03-2021.12)，繪製物候輪並進行貝葉斯迴歸分析，探討植物類群對於溫度與降雨量的敏感性。結果顯示，雪山圈谷共調查34科80屬128種開花植物，以菊科與禾本科為優勢科別；植物生活型譜分析顯示，以半地中植物為優勢生活型。研究區域開花物種特有率為60.16％，依《2017臺灣維管束植物紅皮書名錄》分析評估類別，開花物種共有15種為受脅類別者，包含易危者12種與瀕危者3種：葉芽筷子芥、臺
灣山薺、雪山翻白草。整體看來，開花物候起始於4、5月，6-9月為開花物候高峰期，終止在10月之後。本研究因2012年最接近長期氣象資料而作為基準年進行分析，2012年開花物候始於5月，最高峰為7月，結束於10月。結果顯示部分年度始花提前，推測此主要受全球暖化，冬末初春的相對高溫使物種提早打破休眠而開花；而花期延後結束推測主要受到夏秋維持相對高溫，使物種生長季延後結束。檢視科屬層級開花物候輪，科別早花類群包含柏科、菫菜科、報春花科、小檗科及燈心草科，屬別早花類群則有山芥菜屬、杜鵑花屬、貓兒眼睛草屬、八寶屬；科別晚花類群包含續斷科與桔梗科，屬別晚花類群則有毛蓮菜屬與佛甲草屬。檢視生活型開花物候輪，
挺空∕地上植物偏向較早開花且年際變化較大，地中植物則相反。此外，溫度對於雪山圈谷開花物候影響明顯大過降雨量，每月開花物種數跟當月均溫顯著正相關，物種開花日移動則受到前月均溫較顯著影響。物候輪結合貝葉斯迴歸模型，驗證雪山圈谷早花物種 (玉山圓柏、雙黃花菫菜、玉山杜鵑) 對於溫度與降雨量較敏感。循環統計應用於雪山圈谷開花物候分析的成效良好，可以處理過去無法妥善解釋雪山圈谷開花物候時間層面，關於年際變化與開花日移動的問題，且彌補線性譜帶未能呈現開花物候月分循環週期的缺點。
