eDNA and specific primers for early detection of invasive species – A case study on the bivalve Rangia cuneata, currently spreading in Europe [PDF]

, 2015
Intense human activities facilitate the successful spread and establishment of non-indigenous aquatic organisms in marine and freshwater ecosystems. In some cases such intrusions result in noticeable and adverse changes in the recipient environments.

Disentangling eukaryotic biodiversity patterns from man‐made environments (port and marina) and nearby coral reefs in the Red Sea: A focus on the surveillance of non‐indigenous species

Environmental DNA, Volume 6, Issue 4, July–August 2024.
Our study focuses on the detection of invasive species across man‐made environments and natural habitats in the central Red Sea. Specifically, we conducted comprehensive DNA analyses using samples collected from two artificial sites, a bustling port and a marina, in comparison with two ecologically sensitive natural sites, coral reefs.

Molecular Phylogenetics of Thecata (Hydrozoa, Cnidaria) Reveals Long-Term Maintenance of Life History Traits despite High Frequency of Recent Character Changes [PDF]

, 2017
Two fundamental life cycle types are recognized among hydrozoan cnidarians, the benthic (generally colonial) polyp stage either producing pelagic sexual medusae or directly releasing gametes elaborated from an attached gonophore.

Cryptic diversity in the leptothecate genera Laodicea and Tiaropsis (Cnidaria: Hydrozoa) [PDF]

, 2022
Postponed access: the file will be accessible after 2022-09-01Although they are an ecologically and economically important group of animals, hydrozoans are understudied because of their difficult identification due to their small size and fragility ...

Investigating pelagic biodiversity and gelatinous zooplankton communities in the rapidly changing European Arctic: An eDNA metabarcoding survey

Environmental DNA, Volume 6, Issue 3, May–June 2024.
In this study, we implement eDNA metabarcoding to investigate patterns of pelagic diversity in the European Arctic. We successfully detected a wide range of taxa belonging to the marine metazoan and gelatinous zooplankton communities. We demonstrate vertical patterns of diversity as well as relationships between taxa and water mass indicators such as ...

Phylogenetic placement of the enigmatic parasite, Polypodium hydriforme, within the Phylum Cnidaria

BMC Evolutionary Biology, 2008
Background Polypodium hydriforme is a parasite with an unusual life cycle and peculiar morphology, both of which have made its systematic position uncertain.

Autonomous eDNA collection using an uncrewed surface vessel over a 4200‐km transect of the eastern Pacific Ocean

Environmental DNA, Volume 6, Issue 1, January–February 2024.
An uncrewed surface vessel and an automated eDNA sample collection device were used to obtain eDNA samples over a 4200‐km, 29‐day voyage in the eastern North Pacific Ocean. The results of the study revealed important technical considerations for acquiring samples autonomously and highlight how these platforms can increase the accessibility of obtaining

Phylogenetics of Trachylina (Cnidaria: Hydrozoa) with new insights on the evolution of some problematical taxa [PDF]

, 2017
Some of the most interesting and enigmatic cnidarians are classified within the hydrozoan subclass Trachylina. Despite being relatively depauperate in species richness, the clade contains four taxa typically accorded ordinal status: Actinulida ...
