How to quantify the complexity of a biological community
In short: Measuring biodiversity requires more than just counting species. This video explains how Simpson's index of diversity allows ecologists to compare the health and variety of different ecosystems.
The lesson explores how species number and relative abundance work together to define community diversity. By using Simpson's index of diversity, researchers can move beyond simple observations to mathematically quantify and compare the ecological variety found in different environments.
