Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Bottlenecks and rescue effects in a fluctuating population of golden-mantled ground squirrels (<i>Spermophilus lateralis</i>) (2011), Conservation Genetics. Implementations in other papers (listed below) may differ.

1. Bottleneck simulation modeling
   Used BOTTLESIM to create simulated datasets based on founder population using number of alleles, allele frequencies, and population size from year of highest abundance prior to demographic bottleneck (1997). Ran model for 1,000 iterations assuming random mating, age of reproductive maturity = 1 year, expected longevity = 2 years, and 10% generation overlap
   Quantities: 1,000 simulation iterations, founder population based on 1997 data (62 genes)Duration: Computational simulation period covering 8 years (1997-2005)Conditions: Closed population simulation with no immigration
   Equipment: BOTTLESIM software
