Summary In this study, we investigated microbial communities (bacteria and protist) in two coastal areas near the estuaries of Liaohe (LH) River Yalujiang (YLJ) Northwestern Pacific Ocean. Due to existence Liaodong Peninsula different levels urbanization, geographical segregation significant environmental heterogeneity were observed between these areas. There significantly regional species pools biogeographic patterns for both bacterial protistan LH YLJ Species turnover was main mechanism...
Coastal regions support the most threatened ecosystems on Earth, and anthropogenic activities have been significantly affecting both habitat structure ecological quality. Understanding dynamics of response to multiple stresses is a precondition for management restoration largely disturbed coastal ecosystems. Among diverse taxa in regions, benthic organisms are widely recognized as promising targets assessing causes consequences activity-derived stressors, such environmental pollution....
As an important carbon sink, seaweed cultivation plays a vital role in controlling global climate change. However, most studies have been focused on the itself, and knowledge of bacterioplankton dynamics activities is still limited. Here, total 80 water samples were obtained from coastal kelp area adjacent non-culture seedling mature stages. The communities analyzed using high-throughput sequencing bacterial 16S rRNA genes, microbial genes involving biogeochemical cycles measured by...
Phytoplankton and microzooplankton are crucial players in marine ecosystems first responders to environmental changes, but their community structures how they shaped by conditions have rarely been studied simultaneously. In this study, we conducted an eDNA metabarcoding sequencing combined with multiple statistical methods simultaneously analyze the phytoplankton Liaohe (LH) Yalujiang (YLJ) estuaries. The major objective was examine plankton structure assembly mechanism may differ between...
Estuaries are increasingly threatened by pollutants derived from human activities, which severely impair their water quality, biodiversity, and ecological functions. Therefore, within this context, it is essential to conduct comprehensive scientifically rigorous assessments of estuarine quality. Taking the Yellow River estuary as a case study, composite index was here developed evaluate impacts eutrophication heavy metal pollution on The Trix potential risk revealed significant risks...
We observed two ultrabroadband near-infrared (NIR) luminescence bands around 1.2 and 1.5 μm in as-grown bismuth-doped CsI halide crystals, without additional aftertreatment. Dependence of the NIR emission properties on excitation wavelength measurement temperature was studied. Two kinds active centers subvalent bismuth color were demonstrated to coexist Bi:CsI crystal. The eye-safe band with an FWHM 140 nm lifetime 213 μs at room makes crystal promising applications ultrafast laser amplifier.
The absorption, excitation, and ultrabroadband near-infrared luminescence spectra of Bismuth were investigated in H(2)-annealed gamma-irradiated Bi:alpha-BaB(2)O(4)(alpha-BBO) single crystals, respectively. Energy-level diagrams the luminescent centers fixed. electronic transition energies active are basically consistent with multiplets free Bi(+) ions. minor difference energy-level ions Bi:alpha-BaB(2)O(4) crystals can be ascribed to local lattice environments. involved physical chemical...
Rodent pest management traditionally relies on some form of lethal control. Developing effective fertility control for rodent species could be a major breakthrough particularly in the context managing population outbreaks. This laboratory-based study is first to report effects using compounds an outbreaking found throughout sub-Saharan Africa. Mastomys natalensis were fed bait containing synthetic steroid hormones quinestrol and levonorgestrel, both singly combination, at three...
Abstract Aim Revealing the ecological mechanisms driving diversity patterns of microbial communities across space and through time is an essential issue in biogeography. This study links spatial scaling with mechanisms, aiming to provide novel mechanistic insights into biogeographic followed by different types microbes. Location Beibu Gulf, a semi‐enclosed oceanic bay located on southern coast China. Taxon Bacteria, which were further classified as abundant rare taxa. Methods By employing...
Spectroscopic properties of Bi-doped SrB(4)O(7) glasses, sintered compounds, polycrystalline materials, and single crystals were investigated. Broadband near-infrared luminescence was realized in glasses with basicity materials non-bridging oxygens. In Bi:SrB(4)O(7) crystals, only visible Bi(3+) Bi(2+) observed, but no near-infrared. The rigid three-dimensional network crystal is proved to be unfavorable for accommodation Bi(+) ions.
Abstract Mesozooplankton communities in marine ecosystems are mainly influenced by both anthropogenic pollutants (e.g. nutrients and heavy metals) natural variables temperature, salinity geographic distance). To achieve a deeper understanding of the effects on mesozooplankton communities, we analyzed community structure from 91 stations representing five typical estuarine regions Bohai Sea assessed relative importance using multiple statistical approaches. Cd was identified as leading...
Ecological qualities and resources in coasts are threatened by various human activities, such as pollution fishery. Impact evaluation of environmental stressors over a wide coastal stretch has been limited due to lack efficient standardizable biodiversity monitoring assessment tools. Integrating DNA (eDNA) ecological traits, holistic approach was developed assess the impact aquaculture on fish Chinese areas. Taking Yalujiang Estuary (YLJK) from Yellow Sea Nan'ao Island Area (NAO) South China...
The integrated assessment of ecological quality in estuarine ecosystems holds significant importance for environmental management. Previous monitoring programs predominantly focused on data, lacking a comprehensive approach. To address this gap, study aimed to integrate factors with macrofaunal community information evaluate the status Yellow River Estuary. A total 13 stations were routinely monitored August four consecutive years collect and biological data. Candidate indicators screened...
The linkages between phytoplankton and zooplankton are crucial for the stability of complex food webs flow energy within marine ecosystem. Despite body size exhibiting multiple effects on planktonic community assembly dispersal scale, its role in determining phyto-zooplanktonic co-occurrence patterns remains unclear. Here, we focused more than 13,000 kilometers Chinese coast to study diatom-dominated plankton ecosystem report significant negative zooplanktonic sizes topological properties...
Organochlorine pesticides (OCPs) have been used worldwide on an enormous scale over the last century but are banned globally due to environmental persistence and ecotoxicity in recent decades. The long-term effects of OCP ban for agricultural use China since 1983 reproductive health small terrestrial mammals never evaluated field. We examined residue dynamics OCPs performance Chinese striped hamsters (Cricetulus barabensis) North Plain during 1983–2010 concluded that exposure levels...
