insular
常考释义
Falls in sea level often exposed a number of important land bridges, such as those linking Alaska to northeast Asia and Britain to northwest Europe, a phenomenon with far-reaching effects not only on human colonization of the globe but also on the environment as a whole - the flora and fauna of isolated or insular areas were radically and often irreversibly affected.
当海平面下降时，一些重要的陆桥会暴露出来，比如连接阿拉斯加与亚洲东北部的陆桥，以及连接英国和西北部欧洲的陆桥，这一现象不仅对人类的殖民，而且对整个环境都有着深远的影响——对于孤立或隔绝区域的植物群或动物群有着彻底的不可逆的影响。
