Sentence examples for population size down from inspiring English sources

Inversely, for a population above the Allee threshold, stochastic effects can decrease population size down to a level where it is highly vulnerable to Allee effects (Grevstad 1999b; Liebhold and Bascompte 2003).

However, environmental stochasticity can interact with demographic stochasticity to increase the extinction rate in small populations, where a random reduction in population growth rate can drive population size down to where the effects of demographic stochasticity come into play (Grevstad 1999b; Drake 2004).

This is supported by the observation that the proportion of noncoding genomic sequences broadly correlates with developmental complexity, reaching over 98% in mammals (Liu et al., 2013), although others have argued that the increase in genome size is due to the inefficiency of selection against non-functional elements as body size goes up and population size goes down (Lynch, 2007).

Control-X chromosomes were expressed hemizygously and the opportunity for sexual selection existed in these populations; while this, along with a larger population size, will slow down the rate of MA, we cannot eliminate the possibility that some deleterious mutations have fixed in these lines.

The likelihood of this happening goes up as effective population size goes down.

We consider the limit as the population size (Nrightarrowinfty) and write down ordinary differential equations (ODEs) for the proportion of the population in phase a and with k social contacts at time t, (p_{a,k}(t)).

While this may seem trivial, in fact many conservation management schemes are designed precisely to protect vulnerable populations from the forces that are driving down population size.

In particular, it is not clear whether increasing the number of loci will help in situations where large effective population size keeps genetic structure down, even with restricted migration.

Finlay says athletics in the UK faces a unique problem that comes down to population size.

One of the most interesting things about the HDI report is its home value analysis of the 50 largest U.S. real estate markets (as broken down by population size of Metropolitan Statistical Area).
