The survival of a salamander population when facing a new predator depends on genetic diversity within the population.
The most important factor to the survival of a salamander population if a new predator is introduced to its environment is a diverse population whose members have various traits. This diversity increases the likelihood that some individuals will possess traits that allow them to survive the new predator's introduction, ensuring the population's overall resilience.
For example, if a new predator targets small salamanders, having larger salamanders in the population may increase survival chances. Conversely, being well adapted to current predators or having little diversity can be risky when facing a new predator.
Overall, genetic diversity within a population promotes adaptability, making it better equipped to respond to environmental changes and threats, such as the introduction of a new predator.
