Invasion genomics of lionfish in the Mediterranean Sea
Lionfish are well‐known for having invaded the Caribbean with devastating ecological effects. Here we study the genomics of a recent invasion of lionfish in the Mediterranean, coming from the Red Sea via the Suez Canal. We found that genetic diversity has not declined during the invasion phase, and some genes potentially under selection may have ...

Formation of the Statolith in the Ctenophore Mnemiopsis leidyi [PDF]
The aboral sensory organ (apical organ) of ctenophores contains a statocyst with a single large statolith. The statolith comprises living cells (lithocytes), each containing a large membrane-bound concretion. The statolith is supported on the distal ends of four compound motile mechanoresponsive cilia (balancers) which control the beat frequencies of ...

Environmental constraints of the invasive Mnemiopsis leidyi in Scandinavian waters [PDF]
We studied the seasonal dynamics of the invasive ctenophore Mnemiopsis leidyi over its distribution range from Skagerrak into the Baltic Proper during 1 yr and related this to ambient physical and biological variables. The appearance of M. leidyi was sporadic in the Baltic Proper, with 60‐fold lower abundance than in the Skagerrak and Kattegat (mean 0 ...

Mnemiopsis leidyi in the northern Adriatic: here to stay?
Mnemiopsis leidyi has successfully made the transition from its native spatial range along the Atlantic coast of North and South America to many areas of the Eurasian seas. In summer 2016, we observed M. leidyi at several sites within the northern Adriatic (Mediterranean Sea).

Extracellular DNA traps in a ctenophore demonstrate immune cell behaviors in a non-bilaterian
The formation of extracellular DNA traps (ETosis) is a first response mechanism by specific immune cells following exposure to microbes. Initially characterized in vertebrate neutrophils, cells capable of ETosis have been discovered recently in diverse ...

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

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.

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

In this study population genetic structure of Mnemiopsis leidyi were examined by 200 samples from the Caspian Sea. Samples were collected from Guilan province (Astara region), Mazandaran province (Amir Abad region), Golestan province (Gomishan region) and north part of the Caspian Sea. 50 samples were collected from each region.
