The reason that this effect has been missed is that theoretical studies have treated w ¯ as a fixed parameter (or, equivalently, they hold population size fixed, as in Robertson's theory of selection limits [ 28]).
The idea of holding populations hostage to annihilation is worse than immoral, they say; it is irrelevant.
Several clubs lease fishing rights for different parts of the river from British Waterways, as it holds populations of bream, three types of carp, chub, dace, eels, perch, pike, roach, rudd and tench.
The state holds populations of white-tailed deer, mule deer, antelope, coyotes, mountain lions, bobcats, elk, and birds such as quail, doves, cardinals, bald eagles, red-tailed hawks, and pheasants.
We may restrict some of our analyses to concession card-holding populations only, as not all opioid medicines of interest are above the general beneficiary copayment amount.
These results are important, since they have implications when using the generalized Zelterman regression approach as discussed in (2.5) for estimating the size of the scrapie affected holding population in Great Britain (observed and hidden number of scrapie-affected holdings).
First, holding population constant is important for measuring how concentrated the hospital industry is – there is a large difference between 500 beds for a population of 5,000 and 500 beds for a population of 50,000.
Dividing the 20 49 sample into six, 5-year age groups and holding population age shares at their 1981 level gives a -.018 decline in the interprovincial share for women vs. -.023 actually seen.
Our intentions with this simple artificial population were to isolate and identify the effects of being an edge city by holding population size and distance to core city constant and equal between edge and non-edge patches.
The form of this relationship influences the estimates of the scrapie-affected holding population and requires further analyses.
