The total branch length of sample genealogies in populations of variable size
Artikel i vetenskaplig tidskrift, 2010
We consider neutral evolution of a large population subject to changes in its population size. For
a population with a time-variable carrying capacity we study the distribution of the total branch lengths of
its sample genealogies. Within the coalescent approximation we have obtained a general expression—
Equation 20—for the moments of this distribution with a given arbitrary dependence of the population
size on time. We investigate how the frequency of population-size variations alters the total branch length.
