Mardi Gras-a carnival held in some countries on Shrove Tuesday (the last day before Lent) but especially in New Orleans.
Bottleneck effect is when there's something that either kills the majority of the population or just prevents it from reproducing. This creates genetic drift because the likelihood of gene prominence changing is much higher in a small population. The Founder Effect is a type of Bottleneck effect. It is when a small amount of individuals starts a population usually due to migration.
In the case of hiking, a bottleneck means the slowest member in walking. An interval between the bottleneck member and the one before spreads, and narrows with the one after. An important thing about bottlenecks is that bottlenecks determine the throughput of a supply chain.If a bottleneck person in hiking can walk faster, the speed of the whole group will increase.Similarly, if the capacity of a bottleneck in a supply chain improves, the throughput will increase. From the definition of bottlenecks, the operating rate of non-bottlenecks is below 100%. bottleneck (or constraint) in a supply chain means the resource that requires the longest time in operations of the supply chain for certain demand. Usually, phenomena such as increase of inventory before a bottleneck and insufficiency of parts after a bottleneck are often seen.
