Topic 3: Biodiversity and conservation
3.1 An introduction to biodiversity
BIODIVERSITY: the variety of all life on earth. It includes genetic diversity, species diversity
and habitat diversity.
- Not constant; changes over time and location
- Looks at different kinds of diversities (species, habitat, and genetic)
- 3 measurements
- Encompasses the total diversity in living systems
Diversity is good for a healthy ecosystem
SPECIES DIVERSITY:
- Component made of 2 variables:
- Species richness: amount of species
- Species evenness: proportions of species
GENETIC DIVERSITY:
- Refers to the range of genetic material present in a population or species (eg: dif cats)
HABITAT DIVERSITY:
- Refers to the range of different habitats, in an ecosystem or biome
*all of these give you a quantification of how healthy an ecosystem is*
