Conservation approaches

Question 1

For effective conservation, need to know nature of threat:

Answer 1

• habitat loss
• introduced species
• overharvesting
• global change

Question 2

How can we protect species threatened by human activities?

Answer 2

• restore or preserve habitat of threatened species
• combat climate change and other global environmental change
• establish regional networks or protected areas
• protect ‘hot spots’ of high biodiversity
• end over harvesting of species in decline

Question 3

IUCn red list

Answer 3

threatened species

Question 4

Main threats =

Answer 4

habitat loss - deforestation
overharvesting - hunting for meat

Question 5

Extinction vortex =

Answer 5

genetic problems for small populations
evidence for this is the effect of introduction of genetic variation

Question 6

How much of the current genetic variation in the population is carried over to the next generation?

Answer 6

Equal to adult population size if all individuals contribute equality to next generation

Question 7

Important factors for population-level conservation

Answer 7

Mating systems and overlap between generations

Question 8

habitat and landscape level conservation

Answer 8

• connecting patches of habitat
• maximise habitat types in landscape
• flagship species concept

Question 9

Zoned reserves =

Answer 9

a landscape approach to conservation
protected areas to cover diversity of habitat types
