Motion, Commotion, and Biophysical Connections at Deep Ocean Seamounts

An application of the theory of island ­biogeography to fish speciation on seamounts

“…The main flow of water across the Hawaiian portion of the chain is from southwest to northeast (Uchida & Uchiyama 1986), and this could mean that connectivity is not as good as might be expected. However, eddies are caused by the seamounts as the current flows through them, and this may retain larvae in the area and facilitate transfer from one seamount to the next (Lavelle & Mohn 2010, Shank 2010. The evidence we reviewed on the wider distribution of the 49 species recorded from only one seamount showed that if they are to be found elsewhere in the Pacific it is usually to the west towards the Indonesian archipelago and the northeast coast of Australia (as shown on the Encyclopaedia of Life; www.eol.org).…”

A biological survey method applied to seafloor massive sulphides (SMS) with contagiously distributed hydrothermal-vent fauna

“…Assuming that larvae can be modelled as passive particles, simply modelling current flow provides an initial estimate of gene flow. More developed modelling at carbonate seamounts (Lavelle & Mohn 2010) using a larval transport Lagrangian model has demonstrated the role of active and passive larval dispersal modes in determining species connectivity and distribution in relation to hydrography. Similar models at hydrothermal vent communities would improve our understanding of the effectiveness of reference plots.…”
