Abstract Molecular tools are an indispensable part of ecology and biodiversity sciences implemented across all biomes. About a decade ago, the use implementation environmental DNA (eDNA) to detect signals extracted from samples opened new avenues research. Initial eDNA research focused on understanding population dynamics target species. Its scope thereafter broadened, uncovering previously unrecorded via metabarcoding in both well‐studied understudied ecosystems taxonomic groups. The...

As the largest semi-closed marine ecosystem in world, Black Sea has been heavily affected by human activities for a long time. Describing biodiversity of multi-trophic biota pelagic zone and identifying dominant environmental factors are prerequisites protecting sustainability ecosystems. However, up to now, taxonomic distributional information about is not clear. Here, we employed Tree-of-Life metabarcoding analyze eight communities Sea, investigated their biogeographical distribution,...

Environmental DNA (eDNA) metabarcoding is at forefront technological advances monitoring, last few years have seen major progress solutions to technical challenges from laboratory bioinformatics. Water eDNA has been shown allow fast efficient recovery signals, but rapid pace...

Human-driven environmental stressors are increasingly threatening species survival and diversity of river systems worldwide. However, it remains unclear how the affect stability changes across aquatic multiple communities. Here, we used DNA (eDNA) data sets from a human-dominated in China over 3 years analyzed communities under persistent anthropogenic stressors, including land use pollutants. First, found that significantly reduced multifaceted (e.g., richness, Shannon's diversity,...

Abstract Freshwater wetlands have experienced disproportionate biodiversity loss due to environmental change. The lack of long-term biological data limits our understanding wetland dynamics and principal drivers. Here, we combine aquatic biomonitoring with satellite-derived imagery spatial-explicit analysis assess the changes in macroinvertebrate diversity driving factors from 1988 2017 Dongting Lake, China. results revealed declining alpha (species richness functional redundancy) but...

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...

The continuous, intense exploitation of resources under rapid industrialization has made the ecological environment resource-based cities increasingly vulnerability. Negative impacts over-exploitation include soil erosion, declines in fertility, water pollution, and ground collapse—seriously threatening survival development cities. We used Huaibei City, one representative coal cities, as a case study for measuring considered interference effects human mining activities, based on typical...

Biological quality elements have been developed worldwide to assess whether a water body is in good status or not. However, current studies mainly focus on single taxonomic group small set of species, often limited by methods morphological identification, and lack further aspects biodiversity (e.g., across taxa multiple attributes) ecosystem functions. Here, we advance framework for assessing the river's ecological based complete data measured environmental DNA (eDNA) metabarcoding...

ABSTRACT Mountain river ecosystems, globally recognized biodiversity hotspots shaped by pronounced landscape heterogeneity, are facing intensifying anthropogenic pressures. However, interactions between and activity on montane fish remain poorly quantified. Taking the Yuan River (Yunnan, China) as a model system, environmental DNA (eDNA) partial least squares structural equation modeling (PLS‐SEM) were coupled to disentangle responses of facets (taxonomic, functional genetic diversity)...

Anti-icing asphalt pavement (AIAP) with salt-storage additive (SSA) has been developed and researched for decades the aim to provide support winter road maintenance in cold regions. This paper presents a comprehensive review of literature synthesizes state art research technological developments SSA incorporated into AIAP. The focus is placed on recent advances anti-icing fundamentals SSA, classification characterization effects performance engineering properties pavement. apparently...

The PM2.5 samples at an urban site (JN) and a suburban (QXT) were simultaneously collected in heavily polluted city North China Plain (Jinan) from March to December 2016, eighteen polycyclic aromatic hydrocarbons (PAHs) analyzed. annual average ∑PAHs concentrations 39.8 ± 36.6 23.6 14.0 ng m–3 JN QXT, respectively, with the highest observed during winter. PHE CHY two most abundant PAHs, accounting for 31.1% 34.2% QXT. Source apportionment analyses results of Principal Component Analysis...

The world's largest rivers are home to diverse, endemic, and threatened fish species. However, their sheer sizes make large-scale biomonitoring challenging. While environmental DNA (eDNA) metabarcoding has become an established monitoring approach in smaller freshwater ecosystems, its suitability for large may be challenged by the extent of cross sections (>1 km wide tens meters deep). Here, we sampled eDNA from multiple vertical layers horizontal locations two lower reach Yangtze River...

The impact of intensive land-based fish culture in Qingdao, China, on the bacterial communities surrounding marine environment was analyzed. Culture-based studies showed that highest counts heterotrophic, ammonium-oxidizing, nitrifying, and nitrate-reducing bacteria were found ponds effluent channel, with lower adjacent area lowest samples taken from 500 m off channel. Denaturing gradient gel electrophoresis (DGGE) analysis used to assess total diversity. Fewer bands observed near channel...

ABSTRACT Introduction: Plant communities and soil factors might interact with each other in different temporal spatial scales, which can influence the patterns processes of wetland ecosystem. To get a better understanding distribution plants wetlands analyze their associations environmental factors, structure types plant eastern shore area Lake Taihu were analyzed by two-way indicator species analysis canonical correspondence (CCA) ordination. The vegetation main affecting distributions...

Maintaining or increasing water retention in ecosystems (WRE) can reduce floods and increase resource provision. However, few studies have taken the effect of spatial information vegetation structure into consideration when assessing effects land use/land cover (LULC) change on WRE. In this study, we integrated remotely sensed leaf area index (LAI) ecosystem process-based Biome-BGC model to analyse impact LULC WRE Beijing between 2000 2015. Our results show that volume increased by...
