America itself has only one precedent for such a political lineage -- the Adamses -- but that was at the dawn of the Republic, when a tiny clique of landed white males held power, and when the population was a fraction of what it is today.
And when the population dwindled — as after the First Crusade, which like a neutron bomb eliminated the infidels but preserved the holy places — you could always dash across the Jordan, like Baldwin the crusader king in 1115, and bring back "poverty-stricken Syrian and Armenian Christians, whom he invited to settle in Jerusalem, ancestors of today's Palestinian Christians".
When the population is growing, more of the dependents are children, and when the population is shrinking, more are older adults, the model indicates.
Apparently, the quadratic (with respect to r) term in (3) causes the method to produce strong overestimates of the life expectancy in cases with strong population growth or decline and when the population stability assumption is violated.
We found that increasing the spatial scale of disturbances (while keeping the overall disturbance rate fixed) can increase population density, but generally only when landscape turnover is slow relative to population dynamics and when the population is somewhat close to its extinction threshold.
Historically, this Census data is critical in allocating the number of Congressional representatives to each state (when a state's population increases, it can mean more representatives in the House of Representatives, and when the population does not grown or shrinks, it can mean fewer).
In theory, N e is an adequate representation of genetic drift in large populations and when the population size has been consistent for a long enough time [ 52].
As a result, female O. taurus could in theory be capable of perceiving population density and when the population density is high, responding adaptively by producing more minor males in their offspring and/or producing major offspring with longer horns.
Simply comparing autosomes to X chromosomes is misleading when individual genes differ in dosage responses and when the population of genes residing on the X is highly biased due to the evolution of sex chromosomes (Vicoso and Charlesworth 2006; Gurbich and Bachtrog 2008).
And when the two populations meet, the results aren't always pretty.
