11. The harmonic mean tends to be dominated by the smallest bottleneck that the population goes through. 12. It's the harmonic mean . 13. The arithmetic harmonic mean can be similarly defined, but takes the same value as the geometric mean. 14. However one may avoid use of the harmonic mean for the case of " weighting by distance ". 15. The geometric harmonic mean can be calculated by an analogous method, using sequences of geometric and harmonic means. 16. The geometric harmonic mean can be calculated by an analogous method, using sequences of geometric and harmonic means . 17. The solution can also be written as a weighted harmonic mean of the initial condition and the carrying capacity, 18. It is more apparent that the harmonic mean is related to the dual of the arithmetic mean for positive inputs: 19. The harmonic mean is related to the other Pythagorean means, as seen in the third formula in the above equation. 20. Interestingly, this is one-half of the harmonic mean of 6 and 4 : 4.8 } }.
