Study Notes
Biodiversity
- The variety of life in all its forms and levels of organization
- There are four levels of biodiversity: species, ecosystem, genetic, and functional.
Species Diversity
- A group of actually or potentially interbreeding natural populations
-
Measures of species diversity:
- Species richness: the number of species
- Species evenness: the relative abundance of species
- Endemicity: the geographic restrictions of species
- Mora et al. (2011) estimated that there are over 8.7 million species on Earth.
- Conservationists classify species by their population and distribution.
-
Why conserve species?
- Economic Value
- Ecological Value
- Scientific/Educational Value
