C) 2.1-2.3 intro to biodiversity, ecosystem services, island biogeography

3) Describe species evenness

Measure of how individual organisms are balanced between different species

4) What can high species richness tell you about an ecosystem?

-indicates a high level of biodiversity and the ecosystem is healthy and stable

-resilience against environmental changes and disturbances.

-variety of habitats and resources

6) What allows genetic diversity to be possible? Or what drives genetic diversity?

-reproduction

-combination of different genes from the parent cells to to offspring leading to new traits

7) Explain what can cause a bottleneck effect. What is the result?

-Storm, flood, any disturbances

-resulting in species becoming endangered due to the disturbances killing off their population becoming smaller and less genetically diverse lead them to be more vulnerable to disturbances

8) Explain ecosystem resilience. Why would one ecosystem be more resilient than the other?

Ecosystem resilience: ability of an ecosystem to return to their original conditions after a disturbance

Why: Ecosystems with high biodiversity tend to be more resilient because they have a greater variety of species that have more niches and roles in the environment

9) what are the 4 categories of ecosystem services we discussed given example for each. (only cultural)

Cultural example: landscapes draw tourists who pay to enter parks which spend money for restaurants, stores, fees

10) what would be the ecological economic impact of deforestation?

Ecological: leads to habitat loss resulting in a decrease in biodiversity

Economic: reduces ecosystem services like impacting agriculture, tourism’s, and fishing
