Considering the inherent limits related to the notion of CI (peak height, population size and structure) and the possible uncertainties in the locus order and distances in genetic maps, we also tested an alternative, formula-based method for CI calculation [ 40].
We analyzed the association between the dates of pandemic onset and peak timing with population size, latitude of population centres, climatic factors averaged during the exponential growth phase by geographic region and international inflow of air traffic and arrivals at seaports in May 2009 using univariate Spearman correlations.
The number of aphids at the population peak equates the maximum population size a plant can sustain.
Because of the stationary behaviors in the relations between the peak shift and the population size or airport traffic of the geographical census areas, the results observed with respect to latitude appear to indicate a genuine difference between the two frameworks.
This programme takes as input the peak position, the R2 value, the population size and the left and right position of the 1 LOD interval.
A linear relationship between peak numbers of bison exiting the park, population size, and snow pack development has been suggested [6], [7].
The prevalence of identical isolates during the epidemic peak, especially considering the high mutation rate and large population size of influenza, could be an indication that selection limited sequence diversity during these epidemic peaks.
We also explored the association between province-level estimates of peak timing, excess death rate, and relative risk with latitude, population size, population density, proportion of children in population, urbanization index, and infant mortality rates.
The population size was at its lowest level at the peak of the ice age [48], and increased quickly when agriculture started.
Moreover, posterior probability distributions of the population size and migration rate parameters showed one clear peak with fairly narrow ranges (see Additional file 7).
