The dispersions considered are of low dispersed phase fraction in which coalescence processes may be assumed to be negligible.
A relationship is expected to exist between the amount of genetic differentiation of allopatric marine populations and their dispersal abilities [ 23], with low dispersing taxa showing higher genetic structuring and a significant correlation between genetic and geographic distance (isolation-by-distance, IBD) compared to those capable of wide dispersal [ 24].
It is this kind of pollution problem -- with low, dispersed, but harmful levels of contamination -- that has proved least amenable to conventional technologies and is likely to be the most valuable niche for plants, Mr. Rock and other experts said.
Finally, they are compatible with the idea of host adaptation to local strains of a parasite with presumably small population size and low dispersing capacity.
The Palierne model succeeded well in describing PP/PA6 uncompatibilized blends with relatively low dispersed phase contents (10 wt%) and failed doing so for those of which the dispersed contents were high (30 wt%).
Further, though cumulative volume size distributions indicate self-similarity, as suggested previously, the number probability density distributions show strong bi-modality at low speed and low dispersed-phase concentration which lessens with increasing concentration and becomes uni-modal at high speeds.
Urban settings, which provide plentiful food sources, are well-suited to sustain high population densities of foxes (34 ), who tend to have small home ranges and low dispersing distances (35, 36 ).
They suggested that the minimum spacing between reserves should be approximately the mean dispersal for the lowest dispersing species, assuming that larvae dispersing longer distances can settle into several reserves along the coast.
For the DLS measurements reported here, the polydispersity index (PDI) indicates the level of polydispersity and ranges from 0 (low dispersity) to 1 (completely disperse).
The number of dispersing FAD individuals is randomly drawn from a binomial distribution, but their identity is determined by fitness, so that individuals with low fitness disperse first.
