Nutrients transport behavior in inlet river in the Yellow River Delta in winter

open access: yesMarine Pollution Bulletin, 2023
The nutrients such as dissolved inorganic nitrogen (DIN, NH4+-N, NO2--N, and NO3--N), dissolved inorganic phosphorus (DIP, PO43-) and dissolved SiO2 (DSi) funneled by the inlet river are the dominant factors to coastal eutrophication. This study investigated nutrient transport process in typical inlet rivers in the Yellow River Delta.

Salinity Effects on Microbial Derived-C of Coastal Wetland Soils in the Yellow River Delta

open access: yesFrontiers in Ecology and Evolution, 2022
Microorganisms play a crucial role in regulating the turnover and transformation of soil organic carbon (SOC), whereas microbial contribution to SOC formation and storage is still unclear in coastal wetlands. In this study, we collected topsoil (0–20 cm)

Research progress of near-infrared fluorescence probes based on indole heptamethine cyanine dyes in vivo and in vitro

open access: yesBMC Chemistry, 2020
Near-infrared (NIR) fluorescence imaging is a noninvasive technique that provides numerous advantages for the real-time in vivo monitoring of biological information in living subjects without the use of ionizing radiation. Near-infrared fluorescent (NIRF)

An overview of ecohydrology of the Yellow River delta wetland [PDF]

open access: yesEcohydrology & Hydrobiology, 2016
The combined effects of geophysical and ecological processes, such as water and sediment load, land use change, eustatic sea level rise, land subsidence, and wetland loss, have produced a dynamic eco-hydrologic environment of the Yellow River delta (YRD) in northern China.

Response of soil carbon fractions and enzyme activities to mowing management on in a coastal wetland of the yellow river delta

open access: yesFrontiers in Marine Science, 2022
Coastal wetlands are considered as important “blue carbon” sink, and mowing management induced by anthropogenic activities is anticipated to profoundly affect soil carbon stocks in coastal wetlands.

Variation in Bacterial Community Structure in Rhizosphere and Bulk Soils of Different Halophytes in the Yellow River Delta

open access: yesFrontiers in Ecology and Evolution, 2022
Soil microorganisms play the important role in driving biogeochemical cycles. However, it is still unclear on soil microbial community characteristics and microbial driving mechanism in rhizosphere and bulk soils of different halophyte species.

Influence of the River Ceasing on Wetland Environment in the Yellow River Delta

open access: yesJournal of Environmental Science International, 2003
The Yellow River began ceasing affected by natural factors and the unreasonable human activities. The flow broke in the Yellow River and water and sediment flowing into the sea decreased, which lowered the speed of newly formed wetland extending to the sea.

Impact of river discharge on hydrodynamics and sedimentary processes at Yellow River Delta [PDF]

open access: yesMarine Geology, 2020
During the Anthropocene, regulating river discharge by high dams may have met the need for water demands in river basins, but resulted in carrying less freshwater and sediment to the sea, inducing land degradation and shoreline retreat in worldwide mega-river deltas. In land-ocean interaction, tide response to water discharge changes plays an important

Deciphering evolutionary dynamics of WRKY genes in Arachis species

open access: yesBMC Genomics, 2023
Background Cultivated peanut (Arachis hypogaea), a progeny of the cross between A. duranensis and A. ipaensis, is an important oil and protein crop from South America. To date, at least six Arachis genomes have been sequenced. WRKY transcription factors (
