Still Enigmatic: Innate Immunity in the Ctenophore Mnemiopsis leidyi [PDF]

Integrative and Comparative Biology, 2019
Abstract Innate immunity is an ancient physiological response critical for protecting metazoans from invading pathogens. It is the primary pathogen defense mechanism among invertebrates. While innate immunity has been studied extensively in diverse invertebrate taxa, including mollusks, crustaceans, and cnidarians, this system has not ...

KEY ELEMENTS OF A SIMULATION MODEL OF HYDROLOGICAL FACTORSOF THE NORTHERN CASPIAN AS ENVIRONMENT HABITAT OF THE СTENOPHORA POPULATION MNEMIOPSIS LEIDY

Юг России: экология, развитие, 2014
Analysis of environmental situation in the Caspian and other basins (the Azov and Black Sea ones) showed that the development of an adequate simulation model of hydrological factors in the Northern Caspian as Mnemiopsis leidyi habitat was impossible ...

Recolonization of germ-free Mnemiopsis leidyi considering different microbial diversity [PDF]

, 2022
The comb jelly Mnemiopsis leidyi counts as one of the most invasive marine species in the world due to its rapid adaptation to new habitats. Since different populations of Mnemiopsis all contain a specific core microbiome, it is assumed that their ...

MicroRNAs and essential components of the microRNA processing machinery are not encoded in the genome of the ctenophore Mnemiopsis leidyi

BMC Genomics, 2012
Background MicroRNAs play a vital role in the regulation of gene expression and have been identified in every animal with a sequenced genome examined thus far, except for the placozoan Trichoplax. The genomic repertoires of metazoan microRNAs have become

Causes of plankton diminishing in the Middle and South Caspian nowadays

Юг России: экология, развитие, 2015
There is shown that degradation of plankton is a result of influence of both biotic (mnemiopsis) and abiotic (concentration of mineral nitrogen) factors in the ecosystem of the Middle and South Caspian.

The homeodomain complement of the ctenophore Mnemiopsis leidyi suggests that Ctenophora and Porifera diverged prior to the ParaHoxozoa

EvoDevo, 2010
Background The much-debated phylogenetic relationships of the five early branching metazoan lineages (Bilateria, Cnidaria, Ctenophora, Placozoa and Porifera) are of fundamental importance in piecing together events that occurred early in animal evolution.

The invasive ctenophore Mnemiopsis leidyi poses no direct threat to Baltic cod eggs and larvae [PDF]

, 2011
Since its invasion in to the Baltic Sea in 2006, the ctenophore Mnemiopsis leidyi has been suspected of seriouspredation on the early life stages of Baltic cod (Gadus morhua callarias L.) due to a temporal and spatial overlap inthe most important cod ...

Ground communities of the Dagestan coast of Caspian Sea in conditions of transgression of the sea and invasy of the Ctenophora Mnemiopsis Leidyi (A. Agassiz)

Юг России: экология, развитие, 2015
Benthic biocenoses of the Dagestan area of the Caspian Sea were studied. Considered distribution, composition and structure benthic in connection with observed change in environmental conditions. Special attention is given influence Mnemiopsis leidyi (A.
