Seasonal blooms of the invasive ctenophore Mnemiopsis leidyi have been recorded throughout Adriatic Sea, affecting ecosystem and its pelagic resources. Gelatinous organisms such as M. release significant quantities excreta labile surface active dissolved organic carbon (DOC) that supports microbial activity. The effects leidyi's presence on heterotrophic prokaryotes (HP), cyanobacteria (CB) nan...

this study evaluates changes in species composition, catch, and cpue of three species of kilkas in the caspian sea from 1961 to 2009. the effects of fluctuations in sea level rise and fall on the catch of kilka as well as the impacts of a recent invasion by mnemiopsis leidyi (ctenophora) were assessed in terms of species composition and cpue of kilkas in the iranian coastal region of the caspia...

Gelatinous zooplankton (GZ) populations are sensitive to climate change such as environmental perturbations, and spatial changes in their abundance biomass may be associated with degraded biota conditions. Big data time series of GZ abundances were used analyze the annual population dynamics gelatinous well mesozooplankton southern Caspian Sea, Iran from 1996, 2001-2006, 2008-2013 2018-2019. Th...
