BLACKSEA_CH11_Specification_5 / Table of Mnemiopsis leidyi alien species abundance and biomass distribution in the Black sea as an indicators for impact on the ecosystem and economy

The table of Mnemiopsis leidyi alien species abundance and biomass includes 24 available datasets with the original values (g/m3; ind/m3) from the Black Sea Database created in framework of the NATO SfP-971818 ODBMS Black Sea Project http://sfp1.ims.metu.edu.tr/ODBMSDB/ and Bulgarian National Monitoring Programme http://bgodc.io-bas.bg/documents/ Being an invasive species but not only alien Mnemiopsis affects the ecosystem even with its presence in the environment. The publications of Vinogradov et al., 2005 and Shiganova et al., 2014 took thresholds for Good Environmental Status (GES) < 4g/m3 (120 g/m2 ) and <5 ind/m3 respectively. In concentration above these thresholds the species affects the ecosystem. The data modifications of Product 1 do not allow correct assessment of this impact on the ecosystem.
