2026 biology talkshow:蘭嶼生態連鎖反應-氣候變遷與爬蟲類浩劫

探討氣候變遷與過度的人工保育如何意外破壞蘭嶼的生態平衡。由於海岸線侵蝕與海龜棲地萎縮，當地的赤背松柏根失去主要食源海龜蛋，被迫轉向大規模獵食原生蜥蜴蛋以維持生存熱量。這種食物來源的轉移對蜥蜴族群造成災難性的打擊，特別是高溫環境讓長尾南蜥被迫放棄護蛋行為，使其族群陷入滅絕危機。透過與綠島相對穩定的生態數據對照，研究強調氣候暖化如何透過食物網的連鎖效應摧毀生物多樣性。最後呼籲保育政策不應僅限於單一物種，應從整體的生態網絡出發，才能有效修復脆弱的島嶼環境。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/5c4eb94374a1 Powered by Firstory Hosting
