Initially, the F deme maintained a population of 7378 until 9778.93 generations ago. From 9778.93 to 3806.774, its size reduced exponentially to population size 4044. A exponential change ensued, culminating in 9363 individuals by 922.5. Starting from 922.5 generations ago, the population has reduced from 9363 to 5194, at a linear rate.
