One advantage of preserving more than one population of an endangered species at more than one location is                   . a. a lower risk of extinction of the entire species if a catastrophe strikes one location; b. higher levels of inbreeding in each population; c. higher rates of genetic drift in each population; d. lower numbers of heterozygotes in each population; e. higher rates of habitat fragmentation in the different locations

Verified step by step guidance

1. Identify the key concept: The question is asking about the advantages of preserving multiple populations of an endangered species in different locations.
2. Analyze each option in relation to conservation biology principles: Consider how each option impacts the genetic diversity, survival, and adaptability of the species.
3. Consider the effects of a catastrophe: Evaluate how having populations in multiple locations might protect a species if one location is affected by a catastrophic event.
4. Assess genetic implications: Think about how each option affects genetic diversity, inbreeding, and genetic drift, which are crucial for the long-term viability of a species.
5. Choose the best option: Select the answer that provides a clear conservation benefit by enhancing the species' chances of survival and maintaining genetic health.

Key Concepts

Population Viability

Population viability refers to the ability of a species' population to survive and reproduce over time. Maintaining multiple populations across different locations reduces the risk of extinction due to localized catastrophes, such as natural disasters or disease outbreaks, ensuring that at least some populations can persist.

Genetic Diversity

Genetic diversity is the total number of genetic characteristics in the genetic makeup of a species. By preserving multiple populations, the overall genetic diversity is enhanced, which helps reduce inbreeding and increases the resilience of the species to environmental changes and diseases.

Metapopulation Dynamics

Metapopulation dynamics involve the interactions between multiple populations of a species that are separated by space but interact through migration. This concept highlights the importance of maintaining several populations, as it allows for gene flow between them, which can help mitigate the effects of genetic drift and enhance overall population stability.
