The rich and special biodiversity in mountain rivers is experiencing a continuous decline due to the influence of climate change anthropogenic factors. To explore alterations distribution aquatic context cascade dam development, environmental DNA (eDNA) metabarcoding technique was used examine Wujiang River, representative river with an 11-stage dam. In this study, comprehensive analysis organisms River mainstem conducted, 17 phyla 38 classes were detected 36 water samples. most abundant group benthic organisms, least amphibians. results diversity showed clear longitudinal pattern along altitudinal gradient, higher richness organism communities further lower reaches. Meanwhile, RDA revealed that altitude, dissolved oxygen, reservoir length, construction time key factors influencing mainstem. findings research also applicability eDNA method detecting biodiversity.

Environmental DNA (eDNA) technology has revolutionized biomonitoring, but challenges remain regarding water sample processing. The passive eDNA sampler (PEDS) represents a viable alternative to active, filtration-based enrichment methods, the effectiveness of PEDS for surveying biodiverse and complex natural bodies is unknown. Here, we collected using filtration glass fiber filter-based (submerged in 1 d) from 27 sites along final reach Yangtze River coast Yellow Sea, followed by metabarcoding analysis fish biodiversity quantitative PCR (qPCR) critically endangered aquatic mammal, finless porpoise. We ultimately detected 98 species via metabarcoding. Both sampling methods captured comparable local richness revealed largely similar spatial variation assemblages community partitions between river sea sites. Notably, porpoise was only at five Also, species-specific qPCR that more (7 vs. 2), greater quantities, with higher detection probability (0.803 0.407) than did filtration. Our results demonstrate capacity biodiversity, support continuous collection can be effective instantaneous capturing low abundance ephemeral waters. Thus, approach facilitate efficient convenient eDNA-based surveillance rare detection.

Alpine lakes play pivotal roles in plateau hydrological processes but are highly sensitive to climate change, yet we lack comprehensive knowledge of their multitrophic biodiversity patterns. Here, compared the characteristics diverse taxonomic groups across water depths and surface sediments from a freshwater lake hypersaline on northwestern Tibetan Plateau. Using multi-marker environmental DNA metabarcoding, detected 134 cyanobacteria, 443 diatom, 1,519 invertebrate, 28 vertebrate taxa. Each group had substantially different community composition two lakes, differences were also found between within each lake. Cooccurrence network analysis revealed higher complexity, lower modularity, fewer negative cohesions lake, suggesting that high salinity may destabilize ecological networks. Our results provide first holistic view under contrasting levels reveal structural networks impact ecosystem resilience.

The escalating environmental changes are imposing multiple pressures on biodiversity conservation, thereby, more attention has been paid to fish diversity and community assembly patterns. Fish in Liaohe River deteriorated significantly due overfishing, pollution other reasons, addition, no survey related research published National Park recent years. In order study the of species area investigate presence any invasive species. This used eDNA metabarcoding explore distribution communities Park. showed that a total 54 from six orders, 14 families, 39 genera were detected, meantime, Lepomis cyanellus was found at two sampling sites. α-diversity results estuarine sites had highest diversity. spatial structure upstream downstream reaches similar as indicated by non-metric multidimensional scaling. our study, is influenced both deterministic stochastic processes, with processes being main factor. potential existence L. might be resulted aquaculture, ornamental pet trade, economic farming, artificial release. relatively low number this may attributed limited events addition these factors, over exploitation resources, water pollution, invasion alien have directly impacted aquatic life. lay foundation for future investigation Parks China, use monitoring crucial prevent, control limit spreading advance.

Abstract In Lar National Park (Caspian Sea basin, Iran), the Caspian trout ( Salmo caspius ) population faces different threats, including introduced fish species. Due to harsh environmental conditions and limited accessibility, monitoring of species via conventional approaches proves difficult. Hence, DNA metabarcoding may prove an appropriate tool for fishes within park. Environmental samples from eight stream sites in were sequenced 12S rRNA gene, identified eDNA compared results electrofishing performed at same localities on day. No significant difference number sequence reads was detected among collection p > 0.05). The highest Dalichay Stream, but density determined Siahpalas Stream. discrepancy between read count density, as well sampling scheme this study, limit our ability provide a robust conclusion about application assessment Park. more than electrofishing, no differences composition local community observed. Introduced all observed or which is characterized by high water temperature, muddy substrate, lower flow rate. A effect rate total dissolved solids presence = 0.02) alone relative abundance 0.03) detected. To standardize biodiversity Park, future studies should characterize parameters that affect persistence detectability system.
