About the connection of Mnemiopsis leidyi size structure in the Black Sea with dynamics of its growth and reproduction

open access: yes, 2005
It has been shown that Mnemiopsis leidyi like the other ctenophora has very fast linear growth close to exponential one. It is important these animals are "capable under deficiency of food to "reverse growth" (size diminishing) and morphology of ...

The impacts of Mnemiopsis leidyi on Kilka resources in the southern Caspian Sea

open access: yes‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2001
There are 3 species of kilka in the Caspian Sea consist Of: Clupeonella engrauliformis, C. grimmi and C. cultriventris. These species are caught by fishing method of tunnel net with underwater light in the inshore waters (depths of 40-100m).

Effect of food conditions on ingestion rate and digestion time in lobate ctenophore Mnemiopsis leidyi

open access: yes, 2005
Effect of food conditions (food concentration, volume of the experimental bottles) on ingestion and clearance rates as well as digestion time has been studied in lobate ctenophore Mnemiopsis leidyi, the invader to the Black Sea.

COÖRDINATION AND MOVEMENT OF THE SWIMMING-PLATES OF MNEMIOPSIS LEIDYI, AGASSIZ

open access: yesThe Biological Bulletin, 1934
1. The apical organ in the aboral zone is the center from which impulses travel out into the plate rows.2. The aboral impulses synchronize the plate movements in all eight rows except during slow movements.3. At low rates of plate beating each row becomes independent.4.

Digestion time and feeding intensity of the larval ctenophore Mnemiopsis leidyi A. Agassiz (Ctenophora, Lobata)

open access: yes, 2008
Effect of nutrition conditions (food species and concentration, prey and predator sizes, prey number in stomach) on digestion time and ingestion rate in lobate ctenophore Mnemiopsis leidyi larvae have been studied Digestion time of the larvae in length ...

Haplotype distribution and frequency map for Mnemiopsis leidyi.

open access: yes, 2013
Allele (inner circle for ITS) and haplotype (outer donut for COI) distribution map of Mnemiopsis leidyi. Each color indicates a different allele/haplotype. Private alleles/haplotypes are highlighted in grey. Population codes are described in Table 1.

Lethal and sublethal effects of oil, chemical dispersant, and dispersed oil on the ctenophore Mnemiopsis leidyi

open access: yesAquatic Biology, 2015
We established the lethal levels for water-accommodated fractions of Corexit® 9500A chemical dispersant, crude oil (WAF), and dispersed crude oil (CEWAF) for the ctenophore Mnemiopsis leidyi at both 15 and 23°C.

An investigation on abundance and distribution of Mnemiopsis leidyi in Guilan waters, southwest Caspian Sea

open access: yes‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2005
The alien ctenophore Mnemiopsis leidyi which was transported from the Black Sea into the Caspian Sea by the end 1990s has since affected this new ecosystem. We studied the spatial and temporal distribution of the ctenophore from July 2001 to July 2002 in
