The phrase "light dispersal" is grammatically correct and can be used in written English.
Example: The use of frosted glass windows in the office helped to facilitate natural light dispersal throughout the space, creating a bright and airy atmosphere.
With the advent of genetic technology, study of DNA from birds throughout the Black Swift range will help clarify subspecies boundaries, gene flow among colonies, estimate population size, migratory connectivity, phylogeography, and shed light on dispersal.
Under street lighting, the dispersal of fry was significantly delayed (mean time 6 38 h after dusk; p < 0.001, r = 0.39, n = 2413) with a significant proportion (32%) dispersing during daylight hours.
However, larvae were on average lighter at dispersal when they developed alongside mites (Table 1).
In wild barley, the three spikelets form a light, arrowhead-like dispersal unit that both facilitates seed dispersal by animals and aids seed burial.
A lens can be used to focus light—"reversing" the dispersal of light that had gone out of focus.
Phylogeographic analyses shed light on the dispersal history of R. cylindraceus, which probably originated on the Isla de la Juventud.
In light of the dispersal limitation of L. lecanii, spatial structure may be an essential axis of management to ensure the persistence of L. lecanii and preserve the ecosystem services provided by this versatile biocontrol agent in this and similar coffee farms.
We conclude that there are many clear differences in genomic architecture between the sexes studied here which can be at least partly understood in the light of higher dispersal rate of females as compared to males and the unusual structure of the Z-chromosome of the species.
So, in 2012, all I see are individual chinks of light, but no general dispersal of the snail-mail fog, which still envelops the NHS in its icy grip.
