2026 biology talkshow:自然界的生存遊戲-生物的競爭關係 (國中生物單元十)

探討自然界中競爭機制對生態系統的深遠影響，並以台灣本土案例詳盡說明種內與種間競爭的運作方式。引用達爾文與高斯的理論基礎，指出當生物的生態棲位重疊時，資源爭奪將導致族群消長或行為策略的改變。透過台灣二葉松的自疏作用與台灣獼猴的社會階序，讀者能理解同種個體如何因密度依賴效應產生競爭。此外，特別強調外來入侵種如小花蔓澤蘭、銀合歡及斑腿樹蛙，如何憑藉生長優勢、化學排他或資源利用率，對原生種生存空間造成劇烈壓迫。最後總結競爭不僅驅動物種的性狀替換與資源分配，亦是形塑台灣生物多樣性動態平衡的關鍵力量。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/b134a0ad5dc6 Powered by Firstory Hosting
