SCOR Working Group 157

Toward a new global view of marine zooplankton biodiversity based on DNA metabarcoding and reference DNA sequence databases (MetaZooGene)

Hauling in the MOCNESS (P.H. Wiebe, WHOI)

Zooplankton are small animals (many are microscopic) that spend their lives drifting with ocean currents.  They play an essential role in ocean ecosystems, transferring energy and elements (carbon, nitrogen, phosphorus) in marine food webs. Zooplankton eat tiny single-celled organisms, including the phytoplankton that capture the sun’s energy for ocean life. In turn, they are food for larger organisms, including fish, birds, and whales. Zooplankton are ‘rapid responders’ to biological and physical conditions, and are thus useful indicators of environmental variation and climate change. They are a complex assemblage, including more than 6,000 known species spanning most major groups (phyla) of animals.  Many more species are unseen and unknown, with estimates of the unknown ranging widely.  One promising approach to understanding the many questions surrounding biodiversity of zooplankton is through DNA-based analysis. Recent advances in molecular genetics have opened doors to rapid DNA sequencing of complex environmental samples.  Researchers throughout the world are studying marine zooplankton using these novel DNA-based approaches using a variety of techniques, including different target genes and different ways of analyzing the millions of DNA sequences produced.  This working group will facilitate global cooperation, ensure open access to data and direct comparison of results from different studies, encourage standardization of methods for applied uses in ocean assessment, and accelerate progress using novel DNA-based approaches to understand biodiversity and roles of zooplankton in ocean ecosystems.
