Invasion of Danish and Adjacent Waters by the Comb Jelly Mnemiopsis leidyi—10 Years After [PDF]

Open Journal of Marine Science, 2017
The invasive ctenophore Mnemiopsis leidyi, which comes from North America’s east coast, was observed in Danish waters for the first time in 2007. Since then, the new invader has every summer spread in Danish and adjacent waters (i.e. North Sea, Limfjorden, Skagerrak, Kattegat, Belt Sea, Baltic Sea).

Cambrian Sessile, Suspension Feeding Stem-Group Ctenophores and Evolution of the Comb Jelly Body Plan [PDF]

Current Biology, 2019
The origin of ctenophores (comb jellies) is obscured by their controversial phylogenetic position, with recent phylogenomic analyses resolving either sponges or ctenophores as the sister group of all other animals. Fossil taxa can provide morphological evidence that may elucidate the origins of derived characters and shared ancestries among divergent ...

The nascent RNA labelling compound 5-ethynyl uridine (EU) integrates into DNA in some animals [PDF]

BMC Molecular and Cell Biology
Background The detection of de novo synthesized mRNA transcripts is crucial for understanding the regulation of eukaryotic transcription. Using nucleoside or nucleotide analogues to label nascent RNA is potentially jeopardized by the ubiquitous presence ...

Diversity and Physiological Tolerance of Native and Invasive Jellyfish/Ctenophores along the Extreme Salinity Gradient of the Baltic Sea

Diversity, 2021
Global change has led to manifold changes of marine ecosystems and biodiversity world-wide. While it has been shown that certain jellyfish and comb jelly species have increased regionally, it remains to be investigated if this is a general trend or ...

Speciation of pelagic zooplankton: Invisible boundaries can drive isolation of oceanic ctenophores

Frontiers in Genetics, 2022
The study of evolution and speciation in non-model systems provides us with an opportunity to expand our understanding of biodiversity in nature. Connectivity studies generally focus on species with obvious boundaries to gene flow, but in open-ocean ...

Ecological indicators reveal historical regime shifts in the Black Sea ecosystem [PDF]

PeerJ, 2023
Background The Black Sea is one of the most anthropogenically disturbed marine ecosystems in the world because of introduced species, fisheries overexploitation, nutrient enrichment via pollution through river discharge, and the impacts of climate change.
