This study evaluates the Black Sea anchovy population infected by parasitic Ascaridoid Nematode larva in the Southern Black Sea. It assesses the larva’s effect on fish body condition, energy stored in the body, and anchovy growth. For this, anchovies sampled on July 10–31, 2018, from 30 different stations were examined, and 11.8% of the 825 anchovies ...

Abstract The Ascaridoidea are parasites with heteroxenous life cycles. The study shows that fish can be paratenic, intermediate, or final hosts for parasites, and parasitic fauna reflects the feeding behavior of the hosts. Each species of parasites has also different environmental preferences and host specificity.

Molecular phylogeny of Chromadorea supports genus reclassification of Desmodorida and Microlaimida with the description of two new species from the Yellow Sea, China [PDF]
Phylogenetic relationships within the marine Chromadorea are complex, and the taxonomic positions at the family and genus levels remain flexible due to discrepancies between morphological and molecular evidence.

Gnathostoma spinigerum Mitochondrial Genome Sequence: a Novel Gene Arrangement and its Phylogenetic Position within the Class Chromadorea [PDF]
AbstractHuman gnathostomiasis is an emerging food-borne parasitic disease caused by nematodes in the genus Gnathostoma. In spite of their significance as pathogens, these parasites remain poorly understood at the molecular level. In the present study, we sequenced the mitochondrial (mt) genome of G. spinigerum, which infects a range of definitive hosts

Ocean acidification has a strong effect on communities living on plastic in mesocosms
Abstract We conducted a mesocosm experiment to examine how ocean acidification (OA) affects communities of prokaryotes and eukaryotes growing on single‐use drinking bottles in subtropical eutrophic waters of the East China Sea. Based on 16S rDNA gene sequencing, simulated high CO2 significantly altered the prokaryotic community, with the relative ...

Phylogenetic relationships of some spirurine nematodes (Nematoda: Chromadorea: Rhabditida: Spirurina) parasitic in fishes inferred from SSU rRNA gene sequences [PDF]
Abstract: Small subunit rRNA sequences were obtained from 38 representatives mainly of the nematode orders Spirurida (Camallanidae, Cystidicolidae, Daniconematidae, Philometridae, Physalopteridae, Rhabdochonidae, Skrjabillanidae) and, in part, Ascaridida (Anisakidae, Cucullanidae, Quimperiidae).

Abstract Despite being the most important source of liquid freshwater on the planet, groundwater is severely threatened by climate change, agriculture, or industrial mining. It is thus extensively monitored for pollutants and declines in quantity. The organisms living in groundwater, however, are rarely the target of surveillance programmes and little ...
