Global interest in microplastics is increasing, with numerous organisations collecting data on microplastics in the environment. However, disparate sampling, analysis, and reporting methods limit our ability to integrate data, hindering a global understanding of microplastic occurrence, effects and dynamics. Drawing on international directives and collaborations, we present a comprehensive guideline of harmonised and standardi...
First Record of Five Species of Sea Urchins (Class Echinoidea, Five Orders) From the Gulf of AdenNARA Subscribed
The Gulf of Aden (GA) experiences seasonal upwelling phenomena, fostering favorable conditions for diverse marine life. Despite this richness, the known sea urchin species in the Gulf of Aden has been limited to the common long‐spined ( Diadema paucispinum ). Our study aimed to explore and document sea urchin diversity in this region. Through scuba diving and low tide collections from coral reefs and sandbanks, we obtained sam...
This study reveals the diet of pike-perch from two habitats within the Tersko-Caspian region. The feeding habits of pike-perch in the Sulak and Terek rivers and Tersko-Caspian region were investigated based on 354 specimens sampled monthly from a commercial catch in 2019. Their diet consisted of different prey, with fish representing the most important prey group (up to 90%). Rutilus caspicus dominated with a frequency of occu...
Summary Recently, a microbial consortium was shown to couple the anaerobic oxidation of methane to denitrification, predominantly in the form of nitrite reduction to dinitrogen gas. This consortium was dominated by bacteria of an as yet uncharacterized division and archaea of the order Methanosarcinales. The present manuscript reports on the upscaling of the enrichment culture, and addresses the role of the archaea in methane...
Phylogenetic relationships of bitterlings based on mitochondrial 12S ribosomal DNA sequencesNARA Subscribed
Analysis of the nucleotide sequence of the mitochondrial 12S ribosomal RNA gene of 27 species or sub‐species of bitterlings showed that bitterlings comprise an Acheilognathus clade and a Tanakia‐Rhodeus clade, partially supporting an earlier classification based on morphology and karyology. The monophyly of Acheilognathus is confirmed, but that of Tanakia and Rhodeus remains poorly resolved. Within the Tanakia–Rhodeus clade, a...
