Recent dramatic changes in the Black Sea ecosystem: The reason for the sharp decline in Turkish anchovy fisheries
Abstract As a result of eutrophication caused by increased nutrient input via major rivers during the last few decades, the Black Sea ecosystem has been subject to extreme changes in recent years.Expand

Long-term variations of surface chlorophyll a and primary production in the open Black Sea
Extensive data sets on surface chlorophyll a (chl a), depth-integrated primary production (DIPP) and phosphate (PO4, µM) averaged for the upper 25 m layer in 1964, 1973, 1978 and for a period (1980Expand

Invasive ctenophore Mnemiopsis leidyi in the Caspian Sea: feeding, respiration, reproduction and predatory impact on the zooplankton community.
The impact of the invasive ctenophore Mnemiopsis leidyi on the zooplankton commu- nity of the Caspian Sea was quantified according to food consumption and other major physiological activities (i.e.Expand

Effect of starvation on the biochemical compositions and respiration rates of ctenophores Mnemiopsis leidyi and Beroe ovata in the Black Sea
The proximate biochemical composition and metabolic rates of ctenophores Mnemiopsis leidyi and Beroe ovata from the Black Sea were examined with respect to starvation conditions. Although organicExpand
