2025 biology talkshow:身不由己的生存之舞-動物趨性 (Animal Taxis)

from 雷比特生物空中講 · host 雷比特老師

深入分析動物趨性(Animal Taxis),這是一種動物對單一刺激源做出定向反應的運動,並將其與植物的向性(Tropism)和無方向性的動性(Kinesis)進行了區分。首先引用飛蛾撲火的現象作為引言,接著介紹了雅克·洛布(Jacques Loeb)提出的「強制運動論」,該理論將動物行為視為物理化學反應。隨後,詳細闡述實現趨性的三種導航策略:需要比較「上一秒與這一秒」的訊號的斜趨性(Klinotaxis)、依靠成對受器比較兩側訊號的轉趨性(Tropotaxis),以及能夠直接「鎖定目標」的端趨性(Telotaxis)。最後,列舉多個台灣本土生物案例,如台灣家白蟻的趨光性、櫻花鉤吻鮭的趨流性,以及綠蠵龜的趨磁性,用來解釋不同趨性的機制與表現。 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/8fd387a4b8c8 Powered by Firstory Hosting
