Q

Define Habitat Diversity

A

The number of different habitats in an area

2
Q

Define species diversity

A

Number of different species and abundance of each species (species eveness) in an area

3
Q

Define genetic diversity

A

Number of different alleles within a species population

4
Q

Define species richness

A

Number of different species within an area

5
Q

Define species eveness

A

Relative abundance of each species in an area

6
Q

Factors affecting biodiversity

Habitat loss 
Over exploitation (greater demand for reseources)
Urbanisation 
Pollution 
Climate change
7
Q

In situ protection methods

▪▪▪▪

A

Protected areas

Ex situ protection

▪▪▪▪

A

Relocating
Breeding in captivity
Botanic gardens

9
Q

In situ 2 pros and 1 cons

A

Larger population conserved
Less disruptive

Difficult to control poaching and predators

10
Q

Ex situ 2 pro 2 cons

A

Protect individual animals
Used to reintroduce species

Costly and hard to recreate habitat
Less successful
Only small number conserved
