Which information helps scientist determine the survival probability of a population

Answer 1

1. Population size: A larger population size may indicate higher survival probability as there are more individuals to reproduce and maintain genetic diversity.

2. Genetic diversity: A more genetically diverse population is more likely to survive environmental changes or diseases due to a wider range of traits and adaptations within the population.

3. Age structure: A population with a balanced age structure, including a mix of juveniles, adults, and elderly individuals, is more likely to survive compared to populations with skewed age distributions.

4. Reproductive rate: Populations with high reproductive rates, such as frequent and early reproduction, are more likely to survive and bounce back from declines in numbers.

5. Habitat quality: The availability of suitable habitat, food sources, and resources can impact the survival probability of a population. Habitats with high quality resources will support healthy populations.

6. Migration patterns: Populations that can migrate to find new resources or escape unfavorable conditions have a higher survival probability compared to those that are stationary.

7. Predation and competition: The presence of predators and competitors can impact the survival probability of a population, as they can reduce the number of individuals and limit access to resources.

8. Environmental variables: Factors like climate change, pollution, habitat destruction, and natural disasters can impact the survival probability of a population by altering food availability, habitats, and overall environmental conditions.

9. Disease prevalence: The presence of diseases within a population can impact survival probability, especially if the disease is widespread and causing mass mortality. Immune responses and resistance to diseases can help increase survival probability.

10. Human impacts: Human activities such as hunting, habitat destruction, pollution, and climate change can significantly impact the survival probability of a population, often leading to declines in numbers. Conservation efforts and management strategies can help improve the survival probability of populations facing human impacts.
