Which of the following strategies would most rapidly increase the genetic diversity of a population in an extinction vortex? a. Establish a reserve that protects the population's habitat. b. Introduce new individuals transported from other populations of the same species. c. Sterilize the least fit individuals in the population. d. Control populations of the endangered population's predators and competitors.

Verified step by step guidance

1. Understand the concept of an extinction vortex: An extinction vortex is a process where small populations continue to decline in size, leading to reduced genetic diversity and increased risk of extinction.
2. Analyze the options: Consider how each strategy affects the genetic diversity of the population. Genetic diversity is crucial for the survival and adaptability of a species.
3. Evaluate option b: Introducing new individuals from other populations can introduce new genetic material into the population, thereby increasing genetic diversity more rapidly than other methods.
4. Compare with other options: Options a, c, and d may help the population's survival but do not directly or immediately increase genetic diversity as effectively as introducing new genetic material does.
5. Conclude that option b, introducing new individuals transported from other populations of the same species, would most rapidly increase the genetic diversity of a population in an extinction vortex.

Key Concepts

Genetic Diversity

Genetic diversity refers to the total number of genetic characteristics in the genetic makeup of a species. It is crucial for the adaptability and survival of populations, as higher genetic variation increases the chances of individuals possessing traits that can withstand environmental changes and diseases. In conservation biology, maintaining or increasing genetic diversity is essential for the long-term viability of endangered species.

Extinction Vortex

An extinction vortex is a downward spiral in which a population's size decreases, leading to reduced genetic diversity, which in turn makes the population more vulnerable to environmental changes and further declines. This phenomenon can be exacerbated by factors such as habitat loss, inbreeding, and demographic fluctuations. Understanding this concept is vital for implementing effective conservation strategies to prevent species from becoming extinct.

Population Management Strategies

Population management strategies are techniques used to maintain or increase the size and genetic diversity of endangered populations. These strategies can include habitat protection, introduction of new individuals from other populations, and controlling predators or competitors. Each strategy has different implications for genetic diversity, with the introduction of new individuals often being the most effective for rapidly increasing genetic variation in a population facing an extinction vortex.
