The playful elephants tended to be younger but were more curious and active. Eudora, a 40-year-old female in the herd, seemed to be the most playful, consistently showing this trait through out her life while playfulness in some of the other elephants declined with age.
Gentle elephants, which included two 27-year-old females Eleanor and Eliot, caressed and rubbed against others more than the others.
Those that were reliable tended to be those that were most consistent at making good decisions, helped to care for infants in the herd and were calm when faced with threats. Echo and her youngest daughter Ebony seemed to be the most reliable.
Professor Lee said that elephants with these traits tended to be the most socially integrated in the group while those who tended to be less reliable and pushy were more likely to split from the herd.
科学家发现,大象有四种性格,帮助它们的群落在非洲丛林中生存下来。
很多人误以为,有着灰色皮肤、悲伤眼神、迈着缓慢沉重步履的大象性格都是忧郁的。但是科学家现在发现,这种现存最大陆生动物身材不同,性格也不同。
在一项对非洲象的新研究中,研究人员发现大象群落中最常见的四种截然不同的性格——领袖性格、温和性格、顽皮性格和可靠耐劳性格。
科学家称,每种性格都能帮助这种巨型哺乳动物在严酷环境中生存,这在动物王国中几乎是独一无二的。
