Ecology Conservation and Restoration Ecology 2

Question 1

Which concept describes the minimum viable population size needed to ensure a species' long-term survival?

Accepted Answer

Minimum viable population

Answer

Minimum viable population (MVP) is the smallest population size at which a species can persist in the wild given demographic, genetic, and environmental stochasticity.

Question 2

What is the primary goal of ex situ conservation?

Accepted Answer

Preserving species outside their natural habitat

Answer

Ex situ conservation preserves species in controlled environments such as zoos, seed banks, and botanical gardens, away from their natural habitat.

Question 3

The 'debt-for-nature swap' conservation financing mechanism involves:

Accepted Answer

Reducing a country's debt in exchange for conservation commitments

Answer

Debt-for-nature swaps reduce a developing nation's foreign debt in exchange for commitments to fund or protect natural areas domestically.

Question 4

Which restoration technique involves introducing plant species to an area without active site preparation?

Accepted Answer

Passive restoration

Answer

Passive restoration removes stressors and allows natural succession to occur without direct planting or site manipulation.

Question 5

What does the term 'genetic rescue' refer to in conservation biology?

Accepted Answer

Introducing new individuals to increase genetic diversity in inbred populations

Answer

Genetic rescue involves translocating individuals from other populations to increase genetic diversity and reduce inbreeding depression.
