Biodiversity

Front

How is resiliency related to ecosystem diversity?

Back

Ecosystem diversity increases the ability to recover from disturbances.

Front

How can a population bottleneck affect genetic diversity of a population?

Back

It decreases genetic diversity.

Front

How does habitat loss affect specialist species and generalist species?

Back

Specialist species are more affected than generalist species due to their specific habitat requirements.

Front

Is it better to protect habitats or to try to save individual species?

Back

Both are equally important
