The monitoring and management of aquatic ecosystems depend on precise estimates biodiversity. Metabarcoding analyses environmental nucleic acids (eNAs), including DNA (eDNA) RNA (eRNA), have garnered attention for their cost-effective non-invasive biomonitoring capabilities. However, the accuracy biodiversity obtained through eNAs can vary among different organismal groups. Here we evaluate performance eDNA eRNA metabarcoding across nine groups, ranging from bacteria to terrestrial vertebrates, in three cross-sections Yangtze River, China. We observe robust complementarity between data. relative detectability was notably influenced by major taxonomic groups sizes, with providing more signals larger organisms. Both exhibited similar cross-sectional longitudinal patterns. organisms declined metabarcoding, possibly due differential release decay or sizes. While underscoring potential large river biomonitoring, emphasize need interpretation versus This highlights importance careful method selection studies.

Distinct multitrophic biodiversity composition and community organization in a freshwater lake and a hypersaline lake on the Tibetan Plateau

iScience, Год журнала: 2024, Номер 27(6), С. 110124 - 110124

Опубликована: Май 27, 2024

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.

Environmental DNA Reveals Multitrophic Insight into the Mechanism of Community Stability Changes in Shallow Eutrophic Lakes

ACS ES&T Water, Год журнала: 2025, Номер unknown

Опубликована: Янв. 16, 2025

Current management of eutrophic lakes primarily targets nutrient reduction and algal bloom control, often overlooking the organismal mechanisms that drive changes in community stability across multitrophic levels. This study employed environmental DNA (eDNA) to examine seasonal dynamics communities typical shallow Dianchi (plateau) Taihu (plain), exploring how eutrophication stress influences composition, networks, stability. We found plateau plain had their respective dominant taxa diversity seasons. The structure networks composed varied significantly seasons, among which Lake exhibited 17.9% higher connectivity 8.2% greater robustness compared Lake. Dominant played a critical role determining through different pathways; 30% variation was attributed bottom-up effects, with algae as core pathway, while 40% mainly explained by top-down fish pathway. These findings underscore lake-specific changes, providing insights into tailored strategies for based on unique ecological processes.
