We find that these distributions are mostly set by Population II yields, but exhibit a tail that depends on the Population III IMF for z > 5. Thus, a sample of DLA abundance measurements holds the promise to constrain Population III IMF.
Without enough economic growth to keep a politically *ahem* constrained population happy, China's elite risks losing their grip on power.
However, pneumonia epizootics appear to be driven by density-dependence, and thus disease may constrain population growth and size [ 5].
Pneumonia epizootics appear to be driven by density-dependence, serving to constrain population size [ 5], and presumably selecting for the most fit genotypes.
For conservation of highly threatened species to be effective, it is crucial to differentiate natural population parameters from atypical behavioural, ecological and demographic characteristics associated with human disturbance and habitat degradation, which can constrain population growth and recovery.
For Manus, North Fiji, and Lau Basin samples of Ifremeria nautilei, estimates of effective population size using either microsatellite linkage disequilibrium or coalescent analysis could not constrain population sizes among basins, suggesting that within each basin, effective population size is functionally infinite.
I will discuss recent work on using future radio astronomy observations to constrain populations of early universe relics.
ESTs are issued from a wide variety of tissues usually collected from a limited number of individuals and genetically constrained populations and may represent a bias in true allelic variations.
In summary, the results presented here suggest that fitness costs of immunological maintenance and deployment may constrain populations from achieving high levels of resistance, especially in food-limited environments.
