Dispersal and mating patterns determine the fate of naturally dispersed populations: evidence from Bombina orientalis.

ABSTRACT:

Background

In contrast to the explosive increase of a population following biological invasion, natural dispersal, i.e., when a population disperses from its original range into a new range, is a passive process that is affected by resources, the environment, and other factors. Natural dispersal is also negatively impacted by genetic drift and the founder effect. Although the fates of naturally dispersed populations are unknown, they can adapt evolutionarily over time to the new environment. Can naturally dispersed populations evolve beneficial adaptive strategies to offset these negative effects to maintain their population in a stable state?

Results

The current study addressed this question by focusing on the toad Bombina orientalis, the population of which underwent natur
