The Hox-TALE has been wagging for a long time [PDF]

open access: yes, 2014
Hox and TALE proteins interact in a sea anemone, just as they do in flies and mice, indicating that the Hox-TALE system originated very early in animal evolution.Peer ...

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.

Invasion dynamics of the alien ctenophore Mnemiopsis leidyi and its impact on anchovy collapse in the Black Sea [PDF]

open access: yes, 2008
The mechanisms governing the unprecedented 1989-90 anchovy-Mnemiopsis shift event in the Black Sea were evaluated with a coupled model of bioenergetic-based anchovy population dynamics and lower trophic food web structure.

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 ...

The Comb Jelly Mnemiopsis Leidyi in the Black Sea

open access: yes, 2002
Following its transportation in ballast waters, the western Atlantic ctenophore Mnemiopsis leidyi caused a striking damage to the ecosystem of the Black Sea in the early 1990s.

The ctenophore Mnemiopsis leidyi regulates egg production via conspecific communication

open access: yesBMC Ecology, 2018
Background Communication between individuals of the same species is an important aspect of mating and reproduction in most animals. In simultaneously hermaphroditic species with the ability to self-fertilize, communication with conspecifics can be ...

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)

Invasion genomics of lionfish in the Mediterranean Sea

open access: yesEcology 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 ...
