Bottleneck is a sudden decrease of the population in size, usually due to adverse environmental factors. During bottlenecks, a population shrinks temporarily and therefore loses genetic variation. Bottlenecks also result from alterations in gene flow such as decreased migration, expansions into new habitats, or population subdivision.[1]
