Environmental DNA, Volume 6, Issue 6, November–December 2024.We assessed eDNA metabarcoding from surface water, bottom water, and sediment as well as zooplankton metabarcoding for their applicability to identify the known decline in invertebrate diversity along salinity gradients. All approaches identified regional communities, but with varying explanatory power, with none of these methods being able to ...

Bacterial communities associated with the ctenophores Mnemiopsis leidyi and Beroe ovata [PDF]
FEMS Microbiology Ecology, 2012 Residing in a phylum of their own, ctenophores are gelatinous zooplankton that drift through the ocean's water column. Although ctenophores are known to be parasitized by a variety of eukaryotes, no studies have examined their bacterial associates. This study describes the bacterial communities associated with the lobate ctenophore Mnemiopsis leidyi ...

Evolutionary origin of the nervous system from Ctenophora prospective
Evolution &Development, Volume 26, Issue 4, July 2024.This review discusses the evolutionary origin of the nervous system in light of the latest findings in the neuroscience of Ctenophora, one of the most enigmatic and earliest diverging animal lineages. Abstract Nervous system is one of the key adaptations underlying the evolutionary success of the majority of animal groups. Ctenophores (or comb jellies)

Biochemical composition of Mnemiopsis leidyi in the southern Caspian Sea
, 2003 The biochemical composition of the invasive ctenophore, Mnemiopsis leidyi from the southern Caspian Sea was analysed in terms of total fractions of protein, lipid, ninhydrin-positive substances (NPS), polysaccharides ( PS) and low molecular-weight ...

Invasion genomics of lionfish in the Mediterranean Sea
Ecology and Evolution, Volume 14, Issue 3, March 2024.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 ...

OBSERVATIONS OF THE FEEDING MECHANISM OF A CTENOPHORE,MNEMIOPSIS LEIDYI
The Biological Bulletin, 1928 The mode of feeding was studied in young tentacled forms and in the adult Mnemiopsis leidyi. The young capture food with their branched tentacles, and deposit it in the mouth. The adults entangle the food with the small tentacles along the tentacular ridge, and deposit it in the labial trough, whence it is carried to the mouth.Food enters the ...

Extracellular DNA traps in a ctenophore demonstrate immune cell behaviors in a non-bilaterian
Nature CommunicationsThe 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 ...
