Global surveys: CMarZ Steering Group members are working together to achieve global sampling from ships of opportunity and dedicated cruises. Biodiversity of the deep sea: CMarZ is providing new views of zooplankton species biodiversity in the very deepest part of the world oceans and discovering new species in many taxonomic groups. Preliminary Synthesis Conclusions DNA Barcoding: Rosetta Stone for Zooplankton Amphipods 310 species (529 individuals) from Sargasso Sea (2006) and eastern Atlantic (2007).

Boltovskoy Distribution and Abundance: Zooplankton Species Discovery in Southeast Asia Shuhei Nishida (Ocean Research Institute, Univ. of Tokyo, Japan) Shuhei Nishida and CMarZ / JSPS colleagues have carried out field sampling, with comprehensive taxonomic analysis, throughout SE Asia. New species counts are growing: - 15 new species of mysids (Murano et al., 2008) - 1 new genus of copepods (Grygier & Ohtsuka, 2008) - 6 new species of calanoid copepods (Nishida et al., in prep)
- 2 new species of talitrid amphipods (Othman & Azman, 2007) - 1 new species of harpactacoid copepod (Shimono et al., 2007) Training workshops complement research collaborations: - JSPS CMarZ-Asia Workshop on Zooplankton Biodiversity, including census of jellyfishes and jellyfish fisheries in Viet Nam, coral reef dynamics. - LIPI-JSPS Workshop on Zooplankton Biodiversity in Southeast Asia, sampling from coral reefs, mangroves, sandy shores, and estuaries. Distribution and Abundance: Zooplankton Diversity of the Eastern Atlantic Ocean Sigrid Schiel (Alfred Wegener Institute, Bremerhaven, Germany) A comprehensive CMarZ biodiversity survey was carried out on a meridional transit of the Atlantic Ocean in 2007 on RV Polarstern. Deep-sea sampling was carried out to a maximum depth of 5,038 m. 65,869 specimens of 473 species have been sorted and identified on board. 2,043 specimens of 389 species were collected for barcoding. At-sea barcoding determined 122 DNA sequences for 66 species. At-sea taxonomic training workshops were organized for students.

Major groups were identified into species: 20 chaetognaths (2 new species), 199 calanoid copepods, 74 larval fish, 70 decapods, 7 mysids, 10 appendicularians, 8 ostracods. Phenomenal changes in chaetognath community: 1963, 1979 and 2005. Population density reduced to half; species diversity doubled. Biogeographical distributions characterized for the region. Biogeography of chaetognaths in the Indian Ocean Vijayalakshmi Nair, National Institute of Oceanography, Kochi, India Tropical zone Maximum diversity Indo-Pacific species Subtropical zone Cosmopolitan species Surfacing of meso and bathyplanktonic species Transitional zone Maximum faunistic contrast, overlapping of cold & warm water species Distribution and Abundance: Zooplankton Species Discovery in the Celebes Sea Larry Madin, Woods Hole Oceanographic Inst., USA Continuing analysis of
samples is yielding a treasuretrove of new, rare, and/or undescribed species: Regions of Exploration - black lobate ctenophore (genus Bathocyroe) - polychaete worm with prehensile tentacles. Blue-water SCUBA dives yielded salps, medusae, siphonophores and ctenophores. Trawl collections captured midwater fishes, crustaceans, coronate medusae, as well as pteropods and pyrosomes. Examples of Societal Impact to Date Monitoring Ballast Water in Argentine Ports: Project involves monitoring the ballast water of transoceanic ships. Salinity is measured and plankton samples are collected and distributed among 10 specialists in various planktonic groups for identification of both freshwater and marine zooplankton. [Demetrio Boltovskoy] Impacts of a Marine Bioinvasion: Sampling from the Caspian Sea showed striking impacts of an alien zooplankton species. Satellitederived chlorophyll-a concentrations was significantly correlated with biomass of the invasive predatory ctenophore Mnemiopsis leidyi. By consuming grazing zooplankton, M. leidyi may have caused levels of Chl a to rise to unprecedented values (9mg /m3) in the southern Caspian Sea. [Ahmet Kideys] Kideys, A.E. et al. (2008) Research Letters in Ecology Current Limits to Knowledge KNOWN: ~7,000 described species of marine metazoan and protozoan holo-zooplankton. UNKNOWN: There are estimated to be many times more plankton species in the world
oceans than are currently described. Taxonomic groups where species discovery is particularly likely include fragile and rare groups, and cosmopolitan species whose ranges span more than one ocean basin. UNKNOWABLE: All regions of the deep-sea and many unexplored regions and biodiversity hotspots are certain to yield many new species; fragile species will require in situ collection by divers, ROVs or submersibles. Developing Technology DNA barcoding: CMarZ is sequencing a selected barcode gene most usually the mitochondrial cytochrome oxidase I (mtCOI) gene for each of the 7,000 described species of zooplankton. Zooplankton metagenomics: CMarZ is pioneering metagenomic analysis (i.e., the study of genomes recovered from environmental samples) of all metazoans collected by plankton nets. DNA microarrays: DNA barcode database will be used to fabricate DNA chips with recognition sequences for known species to be used for routine sample analysis and eventually autonomous and remote analysis of zooplankton species diversity.
