Exploring fish communities in the mud volcano polluted river using environmental DNA metabarcoding

Environmental Advances, Journal Year: 2024, Volume and Issue: 16, P. 100534 - 100534

Published: April 14, 2024

In ecosystems subjected to environmental disturbances such as mud volcanoes, understanding the dynamics of fish communities is essential for ecological assessment and conservation. This study employs DNA (eDNA) metabarcoding first time explore within a challenging unique environment—a volcano-polluted river. High-throughput sequencing was utilized assess alpha beta diversity, revealing distinct patterns in community composition response discharge activity. The results indicate that affected sites exhibit remarkably different during active inactive discharge, with impact extending downstream river mouth. Notably, application eDNA identified vulnerable species, Rasbora lateristriata, emphasizing its utility detecting high-risk species. Despite challenges species identification reference databases, use longer 16S rRNA fragments offered enhanced taxonomic resolution interspecific sequence variation. approach showcases potential assessing diversity polluted aquatic ecosystems, significance biodiversity surveys monitoring. underscores value an efficient comprehensive tool studying freshwater highlights need expanding databases address genetic coverage gaps, particularly less-studied environments.

Direct Metal Deposition (DMD) is one of the underwater marine additive manufacturing (MAM) technologies known for its capability to build up on semi-finished products. This allows creation complex structures and repair damaged or worn-out areas. Employing this technology needs a lot consideration regarding harsh environment ocean. research endeavours identify nickel-aluminium bronze’s structural characteristics printed underwater. Simulation studies can help analyse grain phase evolution, defects, melt pool behaviour, enabling optimization printing parameters high-quality alloy components. To achieve that control systems machine learning algorithms need developed enhance precision in 3D process moving platform, addressing challenges six distinct vessel movements at sea. integration aims improve accuracy, contributing optimal performance dynamic maritime environments.

Complete mitochondrial genomes and phylogenetic analysis of native and non-native fishes in a national key wetland of China

Frontiers in Environmental Science, Journal Year: 2024, Volume and Issue: 12

Published: Sept. 25, 2024

Fish are considered objective indicators of environmental health and ecosystem stability. Establishing regional reference databases mitochondrial genome sequences from local fish communities can significantly enhance monitoring using DNA (eDNA) analysis. For non-native species, the eDNA technique provides early detection rapid monitoring. It is also crucial to include fundamental genetic information for both native species in databases. This study presents complete genomes 17 inhabiting Baiyangdian Basin, a national key wetland China. The these was analyzed investigate their characteristics, phylogeny determined maximum likelihood (ML) methods. Various analyses were performed, including examination nucleotide composition, evaluation AT-skew GC-skew, analysis codon frequency, determination relative synonymous usage (RSCU) values, assessment selection pressure on protein-coding genes (PCGs). showed that all PCGs underwent purifying selection. Using Xenocyprididae as representative, this investigated tendencies Basin. Significant differences found five 13 PCGs: COI, COII, COIII, Cytb, ATP8. Except ATP8, findings indicated stronger during evolution compared species. Additionally, comparing population ω values those Cytb COIII exhibited greater differential purification than COI COII. These may be result migrate adapt thereby affecting related genes.
