Q

The need for a stud book?

A
  • identifies suitable mating partners
  • prevents inbreeding which reduces the gene pool
  • this can lead to genetic problems

Q

Advantages of captive breeding areas (zoos, parks etc.)

A
  • place of safety compared to natural habitat

- generates revenue from visitors which can be used for conservation

Q

What do keystone species do?

A

Their survival is important for the survival of many other species as they maintain ecological structure of communities

  • seed dispersal
  • provision of food
  • creation of structural habitat features
