A population bottleneck is a significant reduction in the size of a population that causes the extinction of many genetic lineages within that population, thus decreasing genetic diversity. Population bottlenecks have occurred in the evolutionary...

A population bottleneck (or genetic bottleneck) is an evolutionary event in which a significant percentage of a population or species is killed or otherwise prevented from reproducing, and the population is reduced by 50% or more, often by several...

The structural complexity of a habitat dictates the availability of shelter, and shelter may affect population and community structure in many systems. I tested predictions from the shelter bottleneck hypothesis, which proposes that shelter (or refuge) limitation can control population size structure and density...

ABSTRACT Domestication and breeding share a common feature of population bottlenecks followed by significant genetic gain. To date, no crop models for investigating the evolution of genetic variance, selection response, and population diversity following bottlenecks have been developed. We developed a model artificial...
