生态系统动力学,功能和弹性


In this video Paul Andersen explains how ecosystems respond to disruptions. Disruptions can cause changes in the number and variety of organisms. It can also lead to migration, extinction or even speciation. Ecosystems that have a higher biodiversity are able to respond to large disruptions over time.

下一代科学标准生命科学学科核心理念2C:生态系统动力学,功能和弹性

在这段视频中,保罗·安徒生解释了生态系统是如何应对破坏的。破坏会导致生物体数量和种类的变化。它还会导致迁徙、灭绝甚至物种形成。具有较高生物多样性的生态系统能够对长期的大规模破坏作出反应。
