What is the primary difference between Ex situ and In situ preservation?
What is the primary difference between Ex situ and In situ preservation?
- In situ preservation only applies to plants, while Ex situ applies to animals.
- In situ preservation involves maintaining species in their natural habitats, while Ex situ preservation involves conservation efforts outside those habitats. (correct)
- Ex situ preservation is more effective than In situ preservation in all cases.
- Ex situ preservation occurs in natural habitats, while In situ preservation occurs in controlled environments.

Ex situ vs. In situ preservation
Ex situ vs. In situ preservation
Ex situ: preserving species outside their natural habitat; In situ: preserving them within their natural habitat.
Endangered vs. Threatened vs. Vulnerable
Endangered vs. Threatened vs. Vulnerable
Endangered: at high risk of extinction; Threatened: likely to become endangered; Vulnerable: at risk of endangerment

Key Terms
- Biosphere reserves: Designated areas to protect biodiversity.

- Ecologically extinct: Species no longer able to sustain populations in the wild.
- Ex situ conservation: Preservation of species outside their natural habitats.
- Extrinsic values: Values derived from the benefits a species provides to humans.
- Fragmentation: Division of habitats leading to reduced species populations.
- In situ preservation: Conservation of species within their natural habitats.
- Intrinsic value: Value inherent in a species, regardless of its usefulness to humans.
- Minimum viable population (MVP): Smallest population size that can persist over time.
- Population viability analysis (PVA): Modeling tool to predict the likelihood of species survival.
