保护未来。蜜蜂不会在任何时候只专注于最多产的花区,这是有充分理由的。对蜜蜂来说,环境变化很快,它们无法承受花粉和花蜜摄入量的大幅波动....When a lucrative vein of nectar is discovered, the entire colony doesn’t rush off to mine it no matter how enriching the short-term benefits. The colony has internalized a very important natural rule: someday the nectar in that location will stop flowing and they need to be prepared to rapidly reallocate resources to other productive sites. The best way to ensure that there will be a short run is to focus on the long run….As the bees clearly advise through their behavior, overexploiting a rich patch just because it is there is a death trap.
