E-PILOT 獻給不完美世界的混亂讚歌-中度擾動假說

from 雷比特生物空中講 · host 雷比特老師

詳細闡述「中度擾動假說」(Intermediate Disturbance Hypothesis, IDH)的核心理念及其生態學意義。首先指出,不同於傳統認為最穩定環境物種最豐富的觀念,IDH主張生態系統的物種多樣性(Species Diversity)在中等程度的擾動下達到頂峰。接著,資料回顧了生態學家約瑟夫·康奈爾(Joseph H. Connell)在1978年提出此假說的歷史背景,挑戰當時盛行的「競爭排除原則」(Competitive Exclusion Principle)。解釋低度擾動會讓競爭強勢的物種(K-策略者)壟斷,高度擾動只允許生命週期短的物種(r-策略者)生存,而中度擾動則創造出一個動態鑲嵌(dynamic mosaic)**景觀,允許強弱物種共存。最後,透過岩岸潮間帶和熱帶雨林林窗等實例驗證此假說,並討論其在當代保育和棲地管理中的應用價值與面臨的挑戰。 聽完後可以自主進行線上測驗,檢視學習成效喔~(需要登入gemini) 測驗網址  https://gemini.google.com/share/dee902df8f5f Powered by Firstory Hosting
