Gene flow and genetic diversity in naturally fragmented metapopulations of deep-sea hydrothermal vent animals.

Abstract excerpt

The ephemeral nature of deep-sea hydrothermal vents is expected to favor species with good colonization abilities, high dispersal rates, and rapid individual growth rates. Studies of gene flow in vent-endemic species provide glimpses into modes and patterns of dispersal. For some species, gene flow occurs without geographical bias (i.e., island model); their dispersal capabilities probably exceed the sampled...
