Define biodiversity
It is a measure of the variation found in the living world.
What are the levels of diversity
- Habitat
- Species
- Genetic
What is a habitat?
Is where an organism lives
What is habitat biodiversity?
The range of habitats in which different species live is known as the habitat biodiversity
Give an example of habitat biodiversity
Sand dunes, woodland
What is a species?
A group of organisms that can freely interbreed to produce fertile offspring.
They are similar in appearance, anatomy, physiology, biochemistry, and genetics
What is species biodiversity
The range of organisms in a habitat, which contributes to this biodiversity
What is species richness?
The number of different species present in a given habitat
What is a quantitative way of measuring species richness?
- Count the number of different species
- Can use random quadratic technique
- No need to identify the species
What is species evenness?
Takes into account the population size of each species, and it quantifies how equal the community is numerically
What is a quantitative way of measuring species evenness?
- Use random quadrants, count the number of each species or % cover
- Calculate RELATIVE ABUNDANCE
What is genetic biodiversity?
It is the variation between individuals, belonging to the same species.
