A population bottleneck is an event corresponding to the fact that a substantial proportion of the population of a species disappears or is prevented from reproducing. There is a significantly different type of demographic bottleneck called the founder effect, which occurs when a subset of a population is, at least as far as reproduction is concerned, isolated from the main group (it does not disappear The two groups will be independent of each other).
