Jason Ali has just sent his recent paper on subsidence and vicariance in
the Galapagos (Astronomy and Geophysics 57). I think this an important
mechanism, but the islands don't need to be joined to start with for
vicariance to occur.
In the Hawaiian Islands, Hawaii and Maui were originally 8 km apart, but
following volcanc loading are now 50 km apart. Organisms that could
disperse 8 km and maintain a metapopulation would not necessarily be
able to disperse 50 km, and vicariance could result. Does anyone know of
any papers suggesting this for Hawaii (or any other islands)?
