Wolf Population Perfect Paragraph

   The authors found that “ Scandinavian wolves are highly differentiated both from the neighbouring eastern population and from historical Scandinavian wolves.” All of the wolf populations were found to be significantly differentiated. The genetic variability was significantly lower in the Scandinavian wolf population than other populations. A sharp decline in heterozygosity was observed. The decrease in heterozygosity was measured at 30 % per generation which matches the estimate. The addition of a new immigrant to the population increased mean heterozygosity from 0.49 to 0.62. The sharp decline in heterozygosity was thought to be due to inbreeding, The expected loss of heterozygosity for a population of two individuals would be 25% per year. The observed value was 30%, which is relatively close. However the formula is likely not accurate in such small populations. As expected, the addition of the new immigrant and new alleles increased heterozygosity.
