The wild animals that remain here require vast and various dispersal areas to survive drought, predators and human pressure.
Combined with the lingual salt glands [19], this attribute imbues this crocodilian with a great capacity for dispersal over vast distances, easily explaining its extensive geographic distribution from India to the Solomon Islands.
This study aims to understand this fundamental issue in the evolutionary ecology of populations, the apparently contradicting evidence for large scale dispersal mediating vast (re colonisations concurrently with persistent, fine scale genetic discontinuities in older refugial regions.
"The vast majority of seed-dispersal strategies involve wind, water, hitchhiking, or luring animals with an honest reward," Thor Hanson, the author of The Triumph of Seeds, told me.
Distributions of microbial algae can be examined in the context of " Everything is everywhere, but, the environment selects" [ 25], which predicts that microorganisms are globally distributed as a result of their vast population sizes and unlimited dispersal, and whether or not a species becomes established is determined solely by local conditions [ 26],[ 27].
Microbial cosmopolitanism is thought to be driven primarily by the random dispersal pressure generated by vast population sizes of cells below a body-size of approximately 1 mm [ 9].
While Gates leads a prominent public life, managing the dispersal of his foundation's vast riches, Ballmer lives an almost ordinary existence.
Secondly, the frequency distribution of dispersal distances is highly skewed with the vast majority dispersing extremely low distances (Harrington et al. 2005).
edwardsianus overlap over vast areas, but that a barrier may hinder dispersal and genetic mixing of populations of both lineages.
Colonization studies [ 11, 13], the massive production of resting propagules, and the evidence for rapid postglacial colonization of vast areas of the northern hemisphere indicate that dispersal limitation may also be weak.
