Hydrothermal Vent Metacommunity Networks of the North-West Pacific

*Otis Davey BRUNNER, Yuka SUZUKI, Satoshi MITARAI, Evan ECONOMO(OIST)

Hydrothermal vent fields are discrete ‘oases’ of high biological productivity in the deep sea. Local communities of vent-endemic species are spatially isolated but demographically linked forming multi-vent metacommunities. This isolation makes local vent communities particularly vulnerable to anthropogenic disturbances such as deep-sea mining but also makes them an ideal model system to test metacommunity theory. Here, quantitative estimates of dispersal from hydrodynamic models have been combined with graph theory to create spatially explicit metacommunity networks of hydrothermal vents (nodes) in the North West Pacific connected through oceanographic dispersal (edges).
