大象被称为"生态工程师"，到底指什么？
What does calling elephants "ecosystem engineers" mean?
它们推倒小树、踩出水池、传播种子，把密林"修剪"成更开阔多样的生境，惠及许多其他物种；它们的存在本身就在塑造景观。
They knock down saplings, trample water holes and disperse seeds, opening dense forest into varied habitat that helps many species—their presence literally shapes the landscape.

亚洲象为什么会"北迁"，比如云南那群大象？
Why did Asian elephants "migrate north," like the Yunnan herd?
原因往往是栖息地碎片化、食物季节变化与种群恢复后的扩散需求叠加；象群在寻找更合适的资源和通道，提醒我们生态廊道的重要性。
It's usually habitat fragmentation plus seasonal food shifts and post-recovery dispersal—elephants seeking better resources and corridors, a reminder of how vital ecological corridors are.

人象冲突为什么在亚洲许多地方越来越突出？
Why is human-elephant conflict growing across Asia?
森林被公路、农田切割，象群取食作物与人相遇机会变多；保护成效让象多了，但栖息地没同步扩大，矛盾就浮上来了。
Roads and farms fragment forests, raising encounters as elephants eat crops; conservation raised elephant numbers but habitats didn't expand, so tensions surfaced.
