Question

How do invasive species change the diversity index?

Answer 1

Invasive species can have a negative impact on the diversity index of an ecosystem by outcompeting native species for resources, decreasing the population sizes of native species, and altering the overall structure and composition of the community. This can lead to a decrease in species richness and evenness within the ecosystem, resulting in a lower diversity index. Additionally, invasive species may also disrupt the interactions between species and contribute to a decline in ecosystem stability and resilience.
