1998年6月,美国华盛顿大学生物研究中心的诺顿教授在网上“冲浪”时,发现了一则令他极感兴趣的消息,在哥伦比亚境内亚马逊河的支流库巴扎河流域,一种被称之为“塞西利亚”的本地水蛇突然出人意料地销声匿迹了,当地居民则惶恐地解释说是因为那一片水域出现了凶残的“水鬼”……作为一名资源生态学家,诺顿教授当然知道这是一例典型的物种整体迁徙现象,而不是什么“水鬼”在作祟。同时,教授也敏锐地意识到这将是他进行生态研究的一次绝好考察机会,他决定前往库巴扎河流域追踪“塞西利亚水蛇”的迁徙路径。
In June 1998, Professor Norton, from the Center for Biological Research at the University of Washington in the United States, surfed the Internet and found a source of great interest to him. In the Kuzha River basin, a tributary of the Amazon River in Colombia, Suddenly, the local water snake, “Cecilia,” suddenly disappeared, and locals were panicked to explain the cruel “water ghost” in that waters ... As a resource ecologist, of course, Professor Norton knew This is a typical example of the overall phenomenon of species migration, rather than what “water ghost” at work. At the same time, the professor was keenly aware that it would be an excellent expedition for his ecological research and decided to follow the migration path of the “Cecilia Water Snake” in the Kubicaz Valley.
