Initially, the R deme maintained a population of 6868 until 8491.85 generations ago. From 8491.85 to 5498.4, its size increased exponentially to population size 8466. A linear change ensued, culminating in 1786 individuals by 2073.0. Starting from 2073.0 generations ago, the population has reduced from 1786 to 1395, at a exponential rate.
