High gene flow

Katz, L.A., McManus, G.B., Snoeyenbos-West, L.O. et al. (2005). Reframing the "everything is everywhere" debate evidence for high gene flow and diversity in ciliate morphospecies. Aquatic Microbial Ecology 41, 55-65. 

UTHICKE s and benzie j a h (2000) AUozyme electrophoresis indicates high gene flow between populations of Holothuria (Microthele) nobilis (Holothuroidea Aspidochirotida) on the Great Barrier Reef. Marine Biology, 137,819-825. 

At any event, microorganisms remain far less known than conspicuous species. Microorganisms are subject to high dispersal, as in the recently discovered gene flow for planktonic foraminifers of Arctic and Antarctic waters (Darling 2000). The composition ofthe soil may be also relevant (Yaalon 2000). This is why making an estimate of the diversity of natural products is difflcult. 

As a result of water availability, variety of soils and microhabitats, physical gradients, rough terrain and relative isolation, mountains create altitudinally segregated life zones at short distances and physical barriers to gene flow, which are conditions favoring the development of high species diversity.
