美國的一項(xiàng)研究顯示,蟻群也有個性,而這種個性的形成是由環(huán)境所致。這項(xiàng)刊登在《皇家學(xué)會學(xué)報(bào)B輯》(Proceedings of the Royal Society B )上的研究報(bào)告說,許多由數(shù)以千百計(jì)螞蟻組成的螞蟻群顯示了不同的行為表現(xiàn),這點(diǎn)與人類非常相似。以下是BBC記者 Jonathan Webb的報(bào)道:
According to ecologists, having a personality means showing a consistent pattern of behaviour over time. Researchers from the University of Arizona studied colonies of rock ants across the western US, both by following them in the wild and by taking whole colonies back to the lab.
They found that certain risky behaviours, like foraging widely for food and responding aggressively to a threat, went together and colonies further north tended to take more of these risks.
The study suggests those more adventurous personalities could be an adaptation to the limited window of activity left by the long, snowy northern winter.
