This study provides the first basin-scale assessment of polychlorinated biphenyls (PCBs) and dichlorodiphenyltrichloroethane (DDT) in zooplankton collected from the central-southern Mediterranean Sea....
The European Flat Oyster Ostrea edulis, once widespread across European coastal waters, has experienced severe population declines due to overexploitation, habitat degradation and disease, and is now ...
A new species of Calicotyle (Monogenea: Monocotylidae) is described from three deepwater catshark species (Elasmobranchii: Pentanchidae) collected off Iceland. Calicotyle carmenae n. sp. is diagnosed ...
Microbacterium sp. HM-570 (16S rDNA sequence similarity 99.03% with the closest species Microbacterium lacus A5E-52T) is a sponge-associated bacterium isolated from deep-sea sponge, collected at the H...
A facultatively anaerobic, thermophilic, Gram-negative bacterium, strain sy37T, isolated from a deep-sea hydrothermal field and belonging to the candidate phylum WOR-3, was characterized in detail. Th...
The genus Gnathophis differs from other genera of Congridae in having a moderately blunt and rounded tail tip and a slightly hardened tail extremity. The fleshy tip of the snout extends distinctly for...
Codlets (Bregmacerotidae) play a major role in marine ecology, acting as trophic links between primary consumers and higher predators in mesopelagic communities; however, little information has been a...
Bacterial symbiosis is well-documented in chemosynthesis-based ecosystems, but associations with microeukaryotes remain overlooked. In this study, using scanning electron microscopy and 18S rDNA barco...
Spermatozoa represent one of the most sensitive stages of the life cycle in broadcast spawners, as they are directly released into the water column and immediately exposed to environmental contaminant...
Bacteria are a major component of deep-sea communities. Mesoscale changes were observed in the deep western Mediterranean by analysing deposited DNA in four sediment cores from SE Barcelona, at 1050 m...
A novel Gram-stain-negative, non-flagellated, non-motile, rod-shaped bacterial strain, designated 502str34T, was isolated from deep-sea sediment. The strain was positive for oxidase, catalase and urea...
Environmental DNA (eDNA) metabarcoding provides a non-invasive tool for monitoring marine biodiversity in complex ecosystems. In this study, we applied eDNA techniques to investigate the spatiotempora...
Secondary adaptation of amphibians to marine environments is exceptionally rare. The crab-eating frog, Fejervarya cancrivora, is the only known amphibian capable of completing its life cycle in intert...
Coral reef ecosystems in the South China Sea (SCS) represent globally significant biodiversity hotspots but are increasingly threatened by environmental change and anthropogenic pressures. In this stu...
Reports of cryptic species have increased in recent decades, driven by advances in molecular studies and accessibility of DNA sequencing, resulting in integrative taxonomy as the standard for species ...
Princaxelia Dahl, 1959, is a genus containing predatory pardaliscid amphipods, typically captured in small numbers from hadal trenches (> 6,000 m ocean depth). Here, two new species, Princaxelia maloh...
Environmental DNA (eDNA) offers a non-invasive approach for monitoring cetaceans, yet its widespread application from operational platforms requires standardized and feasible sampling workflows. This ...
The Indo-Pacific humpback dolphin (Sousa chinensis) and the Indo-Pacific finless porpoise (Neophocaena phocaenoides) are increasingly threatened by anthropogenic activity, however the relative influen...
Target capture is widely used to enrich endogenous DNA from calcium phosphate skeletal material in vertebrates, but its performance on calcium carbonate hard parts widely produced by invertebrates rem...
Boundary controllers have been recently proposed in the literature, via modal decomposition, to achieve $H^1$ stabilization of linear parabolic equations in two and three dimensions. In one dimension ...
