Nitric oxide signaling in ctenophores

open access: yesFrontiers in Neuroscience, 2023
Nitric oxide (NO) is one of the most ancient and versatile signal molecules across all domains of life. NO signaling might also play an essential role in the origin of animal organization.

Invasive ctenophore Mnemiopsis leidyi widely distributed in Danish waters

open access: yesAquatic Invasions, 2007
Blooms of Mnemiopsis leidyi observed along the coast of The Netherlands in late 2006 have made the spreading of this invasive ctenophore to neighboring waters a topic of major concern. Here we report on recent occurrences of M. leidyi in Danish waters, observed partly by ourselves and other biologists, partly by beach guests, boat owners and amateur ...

Connectivity and Population Structure in a Marginal Sea—A Review

open access: yesDiversity and Distributions, Volume 31, Issue 7, July 2025.
ABSTRACT Aim The current biodiversity crisis calls for conservation measures that limit or reduce the negative human impact on key habitats and vulnerable wild populations. To effectively protect biodiversity at all levels, including intra‐specific diversity, conservation measures should, ideally, be aligned with the connectivity and genetic structure ...

Microbiota Differences of the Comb Jelly Mnemiopsis leidyi in Native and Invasive Sub-Populations

open access: yesFrontiers in Marine Science, 2019
The translocation of non-indigenous species around the world, especially in marine systems, is a matter of concern for biodiversity conservation and ecosystem functioning.

Zooplankton community structure before and after Mnemiopsis leidyi arrival [PDF]

open access: yesJournal of Plankton Research, 2019
Abstract In the present study, the temporal dynamics of zooplankton community of the North West Adriatic Sea (coastal area of Emilia-Romagna region, Italy) was monitored over 12 years. The distribution and abundance of zooplankton species were investigated in relation to physical and biological parameters (temperature, salinity ...

A Spectacular Northeast Pacific Invasion by a Low Genetic Diversity Parasite, Orthione Griffenis

open access: yesEcology and Evolution, Volume 15, Issue 3, March 2025.
This study examined the genetic structure of the invasive isopod parasite, Orthione griffenis, between Morro Bay, California, and Ketchikan, Alaska, using ddRAD sequencing and estimated its larval dispersal range from laboratory‐based survival tests. There was a lack of genetic diversity, structure, and isolation by distance across O.

eDNA Metabarcoding Applications Across Italian Marine Coastal Ecosystems: An Overview

open access: yesEnvironmental DNA, Volume 7, Issue 2, March/April 2025.
Environmental DNA (eDNA) metabarcoding enhances our ability to protect marine habitats through an integrative assessment of the environmental health status. Here, we provide a time‐based overview of the applications of the eDNA metabarcoding methodology in the Italian marine and coastal ecosystems.

Roaming the Seas—Assessing Marine Invertebrate Biodiversity Along Salinity Gradients With Zooplankton and eDNA Metabarcoding

open access: yesEnvironmental 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 ...

Distribution and abundance of Cladocera, Copepoda and impacts of alien species in the southwestern Caspian Sea during 1996-2014 [PDF]

open access: yesبوم‌شناسی آبزیان, 2019
The Caspian Sea ecosystem has been suffered from many problems since 1980s. Owing to the significance of zooplankton communities in marine ecosystems, the state of the fluctuations of Copepoda and Cladocera species and their relationship with Ctenophora ...

Evolutionary origin of the nervous system from Ctenophora prospective

open access: yesEvolution &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)
