Changes in biodiversity of phytoplankton, zooplankton, fishes and macrobenthos in the Southern Caspian Sea after the invasion of the ctenophore Mnemiopsis Leidyi
Aboulghasem Roohi,Ahmet E. Kideys,Ameneh Sajjadi,Abdolla Hashemian,Reza Pourgholam,Hasan Fazli,Ali Ganjian Khanari,Elif Eker-Develi +7 more
TL;DR: Monitoring for 6 years showed that the population explosion of the alien ctenophore Mnemiopsis leidyi in the southern Caspian Sea coincided with a decline in the abundance and species number of mesozooplankton, and some changes in the macrobenthic fauna were also conspicuous after the increase of this ctenophile.
Journal ArticleDOI
Long-term changes in fecundity of the Kutum, Rutilus frisii kutum Kamensky, 1901, in the Caspian Sea (Osteichthyes: Cyprinidae)
TL;DR: Size and fecundity of the Caspian Kutum has therefore sharply declined during the last six decades and is apparently the consequence of the shift towards smaller fish size.

Mnemiopsis leidyi Invasion and Biodiversity Changes in the Caspian Sea
Aboulghasem Roohi,Ameneh Sajjadi +1 more
TL;DR: The Caspian Sea is the largest enclosed body of water on Earth as mentioned in this paper, having an even larger area than that of the American Great Lakes or that of Lake Victoria in East Africa.
The Effect of the Ctenophore Mnemiopsis leidyi (Ctenophora: Lobata) on the Population Density and Species Composition of Mesoplankton in Inshore Waters of the Caspian Sea
TL;DR: The ctenophore Mnemiopsis leidyi defines the qualitative and quantitative composition of zooplankton community through the control of abundance of copepod and cladoceran nauplii, which, in turn, results in changes in the trophic structure of the whole food chain.
Factors Influencing the Invasion of the Alien Ctenophore Mnemiopsis leidyi Development in the Southern Caspian Sea
Aboulghasem Roohi,Reza Pourgholam,Ali Ganjian Khenari,Ahmet E. Kideys,Ameneh Sajjadi,Ramin Abdollahzade Kalantari +5 more
TL;DR: It seems the sharp decreased of Mnemiopsis abundance could be related the decreasing of ova reproduction; and food ability is the main reasons of M. leidyi sustained in the southern Caspian Sea.
