The 20 questions
-
What is the main goal of captive breeding programmes in zoos?

- Culling excess animals
-
How do seed banks primarily contribute to plant species conservation?
- Selling rare seeds
- Growing commercial crops
- Preventing soil erosion
- Preserving genetic diversity
-
Why do seed banks conduct research into seed germination requirements?
- To induce mutations
- To optimise storage
- To increase value
- To eliminate genes
-
What is the primary conservation benefit of zoo education programmes?
- Increasing gene pools
- Controlling pest species
- Preventing inbreeding
- Raising public awareness
-
Which resource do zoos use to track lineage and prevent inbreeding in captive populations?
- Gene guns
- Studbooks
- Karyotypes
- Pedigree charts
-
Why might reintroduced captive-bred animals struggle to survive in the wild?
- High fertility rates
- Excessive genetic diversity
- Poor survival skills
- Immunity to disease
-
Which ethical issue must zoos weigh against the conservation benefit of captive breeding?
- Species naming rights
- Ecotourism revenue
- Animal welfare
- International trade tax
-
What is the primary measure of success for a zoo reintroduction programme?
- Wild breeding survival
- Captive birth rate
- Enclosure size
- Visitor numbers
-
Why do seed banks store seeds from plants that are not yet extinct?
- Stop herbivore grazing
- Increase soil fertility
- Preserve genetic diversity
- Prevent seed germination
-
What is a major limitation of captive breeding as a conservation method?
- Habitat loss remains
- Genetic diversity increases
- No breeding occurs
- Seeds become dormant
-
Which method assesses whether a reintroduced population is establishing successfully in the wild?
- Post-release monitoring
- Public surveys
- Enclosure expansion
- Pedigree analysis
-
Which term describes conservation of species carried out outside their natural habitat?
- Endemic
- In situ
- Abiotic
- Ex situ
-
How can a zoo increase genetic diversity in a small captive population?
- Enlarge enclosures
- Increase feeding frequency
- Reduce population size
- Exchange breeding stock
-
What factor determines whether in situ or ex situ conservation should be prioritised?
- Main threat type
- Organism body size
- Age of species
- Zoo visitor demand
-
What record is used by zoos to track relationships and prevent inbreeding?
- Herbarium
- Studbook
- Quadrat log
- Seed bank
-
What causes stored seeds in a seed bank to fail to germinate over time?
- Loss of viability
- Over-hydration
- Increased respiration
- High mutation rate
-
Why are seeds kept in cold, dry conditions within a seed bank?
- Increase water potential
- Reduce seed respiration
- Promote germination
- Increase enzyme activity
-
Where does in situ conservation of a species take place?
- In seed banks
- In botanical gardens
- In captivity
- In natural habitat
-
Why do seed banks collect samples from many different wild populations?
- Create hybrid crops
- Prevent pest attacks
- Compare genetic variation
- Increase soil nitrates
