The ratio between the effective and the census population size, Ne/N, is
an important measure of the long-term viability and sustainability of a
population. Understanding which demographic processes that affect Ne/N
most will improve our understanding of how genetic drift and the
probability of fixation of alleles is affected by demography. This
knowledge may also be of vital importance in management of endangered
populations and species. Here, we use data from 13 natural populations of
house sparrow (Passer domesticus) in Norway to calculate the demographic
parameters that determine Ne/N. By using the global variance-based Sobol’
method for the sensitivity analyses, we found that Ne/N was most sensitive
to demographic variance, especially among older individuals. Furthermore,
the individual reproductive values (that determine the demographic
variance) were most sensitive to variation in fecundity. Our results draw
attention to the applicability of sensitivity analyses in population
management and conservation. For population management aiming to reduce
the loss of genetic variation, a sensitivity analysis may indicate the
demographic parameters towards which resources should be focused. The
result of such an analysis may depend on the life history and mating
system of the population or species under consideration, since the vital
rates and sex-age classes that Ne/N is most sensitive to may change
accordingly.
StubberudEtA_Datafile_MolEcol2017The data file contains the individual
information needed to estimate Ne and carry out the sensitivity analyses.
There is one row per year an individual was recorded as adult in the
indicated population. The variables included are: Population (see
information in Table 1); ID (unique individual identity number); Sex
(1=male, 2=female); Year (the year for which the data on the row relates
to); OwnSurvival (0=the individual did not survive to the next year, 1=the
individual survived to the next year); NRecruits (the number of recruits
produced by the individual in the given year). See the paper for further
details on the data.StubberudEtAl_Datafile_MolEcol2017.csv
