1st working group meeting
Hydrothermal vent communities differ dramatically in their taxonomic composition on a global scale, forming distinct ‘biogeographic provinces’ without shared species. We will use a functional trait approach, which offers a common currency to compare vents across these provinces. Our working group aims to build and test a global functional trait database for ephemeral, species poor, high biomass hydrothermal vent ecosystems, using species and community data collected since hydrothermal vents were first discovered nearly forty years ago. We will quantitatively assess spatiotemporal patterns in functional diversity and identify environmental and evolutionary drivers, conservation hotspots and indicators of resilience. Deep-sea mining at hydrothermal vents is expected to begin in 2017 and we expect our findings will inform the guidelines for environmental impact assessment, conservation, and management of deep-sea ecosystems at a time when guidelines are being written and discussed by industry and policymakers. We will: (i) compile, collate, curate and make freely available a database integrating species identities and abundance data for global hydrothermal vent systems; (ii) populate functional trait information for our global database; (iii) test for large-scale biogeographic patterns to identify functional diversity and productivity hotspots and areas of rapid turnover; and (iv) develop indicators of resilience (and associated R code), based on a synthesis of data following natural disturbance events like volcanic eruptions. We will use the results of this work to inform our understanding of which hydrothermal vent communities may be exceptional.
